目标1：理解和运用angularJS的service
目标2：理解和运用控制器继承
目标3：掌握代码生成器的使用
目标4：实现规格管理
目标5：实现模板管理

一、自定义服务:就是将之前的所有与后台请求相关代码抽取出

1.在brand.html中拆分service和controller

    app.service('brandService',function($http){
            this.findAll = function(){
                return $http.get('../brand/findAll.do');
            }
            
            this.add = function(entity){
                return $http.post('../brand/add.do',entity)
            }
            
            this.update = function(entity){
                return $http.post('../brand/update.do',entity)
            }
            
            this.findOne = function(id){
                return $http.get('../brand/findOne.do?id='+id);
            }
            
            this.dele = function(ids){
                return $http.get('../brand/delete.do?ids='+ids);
            }
            
            this.findPage = function(pageNum,pageSize,searchEntity){
                return $http.post('../brand/findPage.do?pageNum='+pageNum+"&pageSize="+pageSize,searchEntity);
            }
        })
    app.controller('brandController',function($scope,brandService){
        $scope.save = function(){      //其他方法都参照修改进行重新调用
                var object = null;
                if($scope.entity.id != null){
                    object = brandService.update($scope.entity);
                }else{
                    object = brandService.add($scope.entity);
                }
                
                object.success(
                    function(response){
                        if(response.success){
                            $scope.reloadList();
                        }else{
                            alert(response.message);
                        }
                    }
                )
            }
        .......
    }

二、代码分离：分离出base，base_pagination，brandService.js，brandController.js

1.pinyougou-manager-web的js目录中增加base_pagination.js和base.js文件

//base_pagination.js内容
var app = angular.module('pinyougou',['pagination']);
//base.js内容
var app = angular.module('pinyougou',[]);

2.pinyougou-manager-web的js目录中增加service文件夹，新增文件brandService.js并拷贝之前service代码

3.pinyougou-manager-web的js目录中增加controller文件夹，新增文件brandController.js并拷贝控制代码

4.在brand.html中进行导入注意导入顺序，注意script必须写全

    <script type="text/javascript" src="../js/base_pagination.js" ></script>
    <script type="text/javascript" src="../js/service/brandService.js" ></script>
    <script type="text/javascript" src="../js/controller/brandController.js" ></script>

三、控制器继承

1.在controller目录中创建baseController.js文件，抽取出如下方法从brandController.js

app.controller('baseController',function($scope){
    //分页控件配置currentPage:当前页   totalItems :总记录数  itemsPerPage:每页记录数  perPageOptions :分页选项  onChange:当页码变更后自动触发的方法 
    $scope.paginationConf = {
        currentPage: 1,
        totalItems: 10,
        itemsPerPage: 10,
        perPageOptions: [10, 20, 30, 40, 50],
        onChange: function(){
            $scope.findPage();
        }
    };
    
    $scope.selectIds=[];//用户勾选的ID集合 
    //用户勾选复选框 
    $scope.updateSelection=function($event,id){
        if($event.target.checked){
            $scope.selectIds.push(id);//push向集合添加元素                     
        }else{
            var index= $scope.selectIds.indexOf(id);//查找值的 位置
            $scope.selectIds.splice(index,1);//参数1：移除的位置 参数2：移除的个数  
        }
    }
    
    $scope.hasCheck = function(id){
        if($scope.selectIds.indexOf(id) != -1){
            return true;
        }else{
            return false;
        }
    }
})

brandController.js优化后的代码为

扫描二维码关注公众号，回复： 5381309 查看本文章 
app.controller('brandController', function($scope,$controller, brandService) {
    //继承,并在方法中参数增加$controller
    $controller('baseController',{$scope:$scope})
    
    $scope.findAll = function() {
        brandService.findAll.success(function(response) {
            $scope.list = response;
        });
    }
​
    $scope.save = function() {
        var object = null;
        if ($scope.entity.id != null) {
            object = brandService.update($scope.entity);
        } else {
            object = brandService.add($scope.entity);
        }
​
        object.success(function(response) {
            if (response.success) {
                $scope.reloadList();
            } else {
                alert(response.message);
            }
        })
    }
​
    $scope.findOne = function(id) {
        brandService.findOne(id).success(function(response) {
            $scope.entity = response;
        })
    }
​
    $scope.dele = function() {
        if (confirm('确定要删除吗')) {
            brandService.dele($scope.selectIds).success(function(response) {
                if (response.success) {
                    $scope.reloadList();
                }
                alert(response.message);
            })
        }
    }
​
    $scope.searchEntity = {};
    $scope.findPage = function(){
            brandService.findPage(
                $scope.paginationConf.currentPage,
                $scope.paginationConf.itemsPerPage,
                $scope.searchEntity).success(
                    function(response){
                        $scope.list = response.rows;
                        $scope.paginationConf.totalItems = response.total; 
                    }       
                )
            }
    })

2.在brand.html中在引入brandController.js文件前导入

<script type="text/javascript" src="../js/controller/baseController.js" ></script>

四、代码生成器生成规格及模版相关文件（之前的品牌也替换掉）

1.没有中文和空格的目录下运行heima_code_util.exe，

生成的包名为com.pinyougou.sellergoods，拷贝文件列表

//sellergoods-interface模块需要拷贝接口文件
BrandService.java,SpecificationService.java,TypeTemplateService.java
​
//sellergoods-service模块需要拷贝实现类
BrandServiceImpl.java,SpecificationServiceImpl.java,TypeTemplateServiceImpl.java
​
//manager-web模块拷贝
BrandController.java,SpecificationController.java,TypeTemplateController.java(修改下包名)
​
//manager-web模块的前端js/controller目录下要拷贝的三个文件
baseController.js,brandController.js,
specificationController.js,typeTemplateController.js
​
//manager-web模块的前端js/service目录下要替换的两个文件
brandService.js,specificationService.js,typeTemplateService.
​
//manager-web模块的前端js目录
base.js,base_pagination.js

五、规格列表

1.在specification.html页面中引入js文件

    <script src="../plugins/angularjs/angular.min.js"></script>
    <script src="../plugins/angularjs/pagination.js"></script>
    <script src="../js/base_pagination.js" ></script>
    <script src="../js/service/specificationService.js" ></script>
    <script src="../js/controller/baseController.js"></script>
    <script src="../js/controller/specificationController.js" ></script>

2.body中增加ng-app="pinyougou" ng-controller="specificationController"

3.td中增加{{entity.属性名取值}},tr中增加ng-repeat="entity in list"

4.增加分页控件 <tm-pagination conf="paginationConf"></tm-pagination>

六、为规格页面的新增弹出框新增行

实现思路：就是通过对entity中定义得sepcOptionList数组增加空对象来完成列表得新增（依赖数据绑定）

1.页面顶部的新建按钮添加点击事件ng-click="entity = {specOptionList:[],specification:{}}" //进行初始化

2.specificationController.js中增加

    //点击增加行的效果
    $scope.addTableRow = function(){
        $scope.entity.specOptionList.push({}); //注意这里是大括弧，大括弧是对象，代表加新对象
    }

3.规格新增按钮增加 ng-click="addTableRow()点击事件

//specification.html
//113行
<tr ng-repeat="pojo in entity.specOptionList">
//115行
<input ng-model="pojo.optionName" class="form-control"  placeholder="规格选项"> 
//118行
<input ng-model="pojo.orders" class="form-control" placeholder="排序">

七、删除规格选项行

1.在删除按钮上调用ng-click="deleTableRow($index)"方法

2.在specificationController.js中增加

    $scope.deleTableRow = function(index){
        $scope.entity.specOptionList.splice(index,1);
    }

八、规格新增

1.在pojo子模块建立com.pinyougou.pojogroup包新增文件Specification

package com.pinyougou.pojogroup;
​
public class Specification implements Serializable{
​
    private TbSpecification specification;
    private List<TbSpecificationOption> specOptionList;
    
    public TbSpecification getSpecification() {
        return specification;
    }
    public void setSpecification(TbSpecification specification) {
        this.specification = specification;
    }
    public List<TbSpecificationOption> getSpecOptionList() {
        return specOptionList;
    }
    public void setSpecOptionList(List<TbSpecificationOption> specOptionList) {
        this.specOptionList = specOptionList;
    }
}

2.在TbSpecificationMapper.xml中的insert部分增加如下代码，目的是插入后将last_insert_id赋值给id属性

	<selectKey resultType="java.lang.Long" order="AFTER" keyProperty="id">
    	select last_insert_id() as id
    </selectKey>

3.SpecificationService接口层修改为

public void add(Specification specification);

4.SpecificationServiceImpl服务层修改为

    @Override
    public void add(Specification specification) {
        
        specificationMapper.insert(specification.getSpecification());
        
        // 设置规格ID
        for (TbSpecificationOption so : specification.getSpecOptionList()) {
            so.setSpecId(specification.getSpecification().getId());
            specificationOptionMapper.insert(so);
        }
    }

5.SpecificationController修改为

public Result add(@RequestBody Specification specification)  //参数去掉tb

6.specification.html，规格名称的输入框中增加ng-model="entity.specification.specName"，保存按钮增加ng-click="save()"方法的调用

7.在specificationController.js文件中对save方法中的判断增加

//if($scope.entity.id != null) 改为
if($scope.entity.specification.id != null) //因为entity对象已经是自己封装的Specification

九、规格修改

1.返回类型改成组合实体类，之前是TbSpecification

public Specification findOne(Long id);

2.修改SpecificationServiceImpl.java

public Specification findOne(Long id){
        //初始化
        Specification specification = new Specification();
        //设置规格对象
        specification.setSpecification(specificationMapper.selectByPrimaryKey(id));
        //查询所有规格选项列表
        TbSpecificationOptionExample example = new TbSpecificationOptionExample();
        com.pinyougou.pojo.TbSpecificationOptionExample.Criteria createCriteria = example.createCriteria();
        createCriteria.andSpecIdEqualTo(id);
        List<TbSpecificationOption> specificationOptionList = specificationOptionMapper.selectByExample(example);
        //设置规格选项
        specification.setSpecificationOptionList(specificationOptionList);
        return specification;
    }

3.修改SpecificationController.java去掉TbSpecification改为Specification

4.页面点击修改按钮调用 ng-click="findOne(entity.id)",

重点修改js中if($scope.entity.specification.id!=null)否则新增跟修改无法正常判断

5.sellergoods-interface的update方法类型改成组合实体类TbSpecification改成Specification

6.sellergoods-service的update方法修改为

public void update(Specification specification){
        //获取规格实体
        TbSpecification tbspecification = specification.getSpecification();
        specificationMapper.updateByPrimaryKey(tbspecification);
        
        //清除原来规格对应的规格选项
        TbSpecificationOptionExample example = new TbSpecificationOptionExample();
        com.pinyougou.pojo.TbSpecificationOptionExample.Criteria criteria = example.createCriteria();
        criteria.andSpecIdEqualTo(tbspecification.getId());
        specificationOptionMapper.deleteByExample(example);
        
        //获取规格选项集合
        List<TbSpecificationOption> specificationOptionList = specification.getSpecificationOptionList();
        for (TbSpecificationOption option : specificationOptionList) {
            option.setSpecId(tbspecification.getId());//设置规格id
            specificationOptionMapper.insert(option);//新增规格
        }
    }

7.manager-web的SpecificationController.java修改update(@RequestBody Specification specification)去掉Tb

十、规格删除

1.在SpecificationServiceImpl.java的dele方法中

    public void delete(Long[] ids) {
        for(Long id:ids){
            //删除规格表数据
            specificationMapper.deleteByPrimaryKey(id);
            
            //清除原来规格对应的规格选项
            TbSpecificationOptionExample example = new TbSpecificationOptionExample();
            com.pinyougou.pojo.TbSpecificationOptionExample.Criteria criteria = example.createCriteria();
            criteria.andSpecIdEqualTo(id);
            specificationOptionMapper.deleteByExample(example);
        }       
    }

2.在页面中的checkbox中增加ng-click="updateSelection($event,entity.id)"，删除按钮增加ng-click="dele()"

十一、模版列表得显示，调整好界面，即后端及前端文件都已拷贝到项目中

1.type_template.html导入步骤一:js相关文件，步骤二:body中增加，步骤三:table下面加分页控件

    <script type="text/javascript" src="../plugins/angularjs/angular.min.js"></script>
    <script type="text/javascript" src="../plugins/angularjs/pagination.js"></script>
    <link rel="stylesheet" href="../plugins/angularjs/pagination.css">
    <script type="text/javascript" src="../js/base_pagination.js" ></script>
    <script type="text/javascript" src="../js/service/typeTemplateService.js" ></script>
    <script type="text/javascript" src="../js/controller/baseController.js" ></script>
    <script type="text/javascript" src="../js/controller/typeTemplateController.js" ></script>
    ...
    <body class="hold-transition skin-red sidebar-mini" ng-app="pinyougou" ng-controller="typeTemplateController">
    ...
    <tr ng-repeat="entity in list">
            <td><input  type="checkbox"></td>                                         
            <td>{{entity.id}}</td>
            <td>{{entity.name}}</td>
            <td>{{entity.brandIds}}</td>
            <td>{{entity.specIds}}</td>                                  
            <td>{{entity.customAttributeItems}}</td>                                                     <td class="text-center">                                           
            <button type="button" class="btn bg-olive btn-xs" data-toggle="modal" data-target="#editModal" >修改</button></td>
    </tr>
    ...
    </table>
    <!--数据列表/-->    
    <tm-pagination conf="paginationConf"></tm-pagination>  

十二、模版新增的品牌下拉列表

1.type_template.html页面引入angular-select2.js文件，编辑框改为select2

    <script type="text/javascript" src="../plugins/angularjs/angular.min.js"></script>
    <script type="text/javascript" src="../plugins/angularjs/pagination.js"></script>
    <link rel="stylesheet" href="../plugins/angularjs/pagination.css">
    
    <script type="text/javascript" src="../js/base_pagination.js"></script>
    //跟多选框相关的引用务必放在base_pagination.js下面
    <script src="../plugins/select2/select2.min.js" type="text/javascript"></script>
    <script type="text/javascript" src="../plugins/select2/angular-select2.js">  </script>
    
    <script type="text/javascript" src="../js/service/typeTemplateService.js"></script>
    <script type="text/javascript" src="../js/controller/baseController.js"></script>
    <script type="text/javascript" src="../js/controller/typeTemplateController.js"></script>
    //关联品牌的增加编辑框
    <td>关联品牌</td>
        <td>
          <input select2  select2-model="entity.brandIds" config="brandList" multiple placeholder="选择品牌（可多选）" class="form-control" type="text"/>
        </td>

2.typeTemplateController.js增加测试数据，为了让页面有下拉选项注意JSON数据格式！！！！！

$scope.brandList = {data:[{id:1,text:'联想'},{id:2,text:'华为'},{id:3,text:'中兴'}]};

3.准备好下拉框后，准备从数据库获取brandList中得内容，在TbBrandMapper.xml文件最后增加

 <select id="selectOptionList" resultType="java.util.Map">
    select id,name as text from tb_brand
  </select>

4.TbBrandMapper.java增加查询规格方法

List<Map> selectOptionList();

5.BrandService.java增加

public List<Map> selectOptionList();

6.BrandServiceImpl.java增加方法

        public List<Map> selectOptionList() {

            return brandMapper.selectOptionList();
        }

7.BrandController.java增加方法

    @RequestMapping("/selectOptionList")
    public List<Map> selectOptionList(){
        return brandService.selectOptionList();
    }

7.brandService.js增加

	//下拉列表
	this.selectOptionList = function(){
		return $http.get('../brand/selectOptionList.do');
	}

8.在typeTemplateController.js中加上brandService的引入

    //读取品牌列表
    $scope.brandList={data:[]}; //可以避免页面的一些初始值错误
    $scope.findBrandList = function(){
        brandService.selectOptionList().success(
                function(response){
                    $scope.brandList = {data:response};
                }
        );
    }

9.在type_template.html中引入brandService.js文件

    <script type="text/javascript" src="../js/service/brandService.js" ></script>
..//body中增加方法的调用
    <body ng-init="findBrandList()>

十三、模版新增的规格下拉列表

1.TbSpecificationMapper.xml增加查询

  <select id="selectOptionList" resultType="java.util.Map">
    select id,spec_name as text from tb_specification
  </select>

2.TbSpecificationMapper.java增加List<Map> selectOptionList();

3.SpecificationService.java增加public List<Map> selectOptionList();

4.SpecificationServiceImpl.java

    }

5.SpecificationController.java增加

    @RequestMapping("/selectOptionList")
    public List<Map> selectOptionList(){
        return specificationService.selectOptionList();
    }

6.specificationService.js增加

    //下拉列表
    this.selectOptionList = function(){
        return $http.get('../specification/selectOptionList.do');
    }

7.在typeTemplateController.js中加上specificationService的引入

    $scope.specList={data:[]}; //可以避免页面的一些初始值错误
    //读取规格列表
    $scope.findSpecList = function(){
        specificationService.selectOptionList().success(
                function(response){
                    $scope.specList = {data:response};
                }
        );
    }

8.在type_template.html页面中引入

    <script type="text/javascript" src="../js/service/specificationService.js" ></script>
    ...
    <body中ng-init="findBrandList();findSpecList()">
    ...
    <td>关联规格</td>
        <td>
          <input select2  select2-model="entity.specIds" config="specList" multiple placeholder="选择规格（可多选）" class="form-control" type="text"/>
        </td>

十四、增加删除扩展属性行

1.在 typeTemplateController.js

    $scope.addTableRow = function(){
        $scope.entity.customAttributeItems.push({});
    }
    
    $scope.deleTableRow = function(index){
        $scope.entity.customAttributeItems.splice(index,1);
    }

2.在type_template.html页面，

新建按钮增加ng-click="entity = {customAttributeItems:[]}"对值进行初始化，

新增扩展属性按钮增加ng-click="addTableRow()"，

删除按钮增加ng-click="deleTableRow($index)"

//扩展属性删除多余的tr，修改tr为动态
<tr ng-repeat="pojo in entity.customAttributeItems">
    <td><input type="checkbox" class="icheckbox_square-blue" ></td>
    <td><input class="form-control" placeholder="属性名称" ng-model="pojo.text"></td>

十六、修改模板

1.type_template.html修改按钮增加ng-click="findOne(entity.id)";

2.typeTemplateController.js中的查询实体方法，增加三处需要将字符串转json对象的地方

    //查询实体 
    $scope.findOne=function(id){                
        typeTemplateService.findOne(id).success(
            function(response){
                $scope.entity= response;    
                $scope.entity.brandIds = JSON.parse($scope.entity.brandIds);
                $scope.entity.specIds = JSON.parse($scope.entity.specIds);
                $scope.entity.customAttributeItems = JSON.parse($scope.entity.customAttributeItems);
            }
        );              
    }

十七、删除模版

1.type_template.html的checkbox部分增加<input type="checkbox" ng-click="updateSelection($event,entity.id)">

2.删除按钮增加ng-click="dele()"

十八、优化模版列表显示，将列表数据转成只有text的内容

1.baseController.js增加

    $scope.jsonToString=function(jsonString,key){
        var json= JSON.parse(jsonString);
        var value="";
        for(var i=0;i<json.length;i++){
            if(i>0){
                value+=",";
            }           
            value +=json[i][key];           
        }
        return value;
    }

2.页面中的属性部分加上{{jsonToString(entity.brandIds,'text')}}
