SpringBoot敏捷开发 使用动软代码生成器 搞定三层架构代码

前言

首先介绍一下 我是一个写过很多年.net 代码的程序员

2010年才转的JAVA开发 

所以一直对@李天平 .net大神级人物 心生崇拜 

此人博客地址为 https://blog.csdn.net/litp/

提到这个人 就不得不提起 动软代码生成器 真乃神器也

但是JAVA web开发中 一直没有一款顺手的 代码生成器

后来公司胡总写了一个 但是修改起来 非得有很强的技术实力不可

于是想到用这个动软代码生成器来逆向生成SpringBoot 代码

具体模板使用方法请参考官方解释

https://blog.csdn.net/litp/article/details/6445672

Entity模板 

所有表名为 t_ 开头 用户表就是 t_user

<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
	TableHost host = (TableHost)(Host);
	host.Fieldlist.Sort(CodeCommon.CompareByintOrder);

    boolean hasDefaultValue = true;
#>

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.persistence.Lob;
import org.springframework.data.rest.core.annotation.RestResource;
import com.fasterxml.jackson.annotation.JsonIgnore;

@Entity
@Table(name="<#= host.GetModelClass(host.TableName) #>")
public class <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>{
<# foreach (ColumnInfo c in host.Fieldlist)
{ #>
	<# if(c.IsPrimaryKey ){#>@Id
    @GeneratedValue(strategy = GenerationType.AUTO)<#}#><#= c.TypeName=="longtext" ? @"@Lob //不建议在主表放置大型文本字段 如果有 推荐使用 一对一关联表存放" : "" #>
	private <#= typeConvert(c.TypeName)#> <#= c.ColumnName.ToString()#><#=hasDefaultValue?getDefaultValueByType(c.TypeName):""#>;
<#}#>
<# foreach (ColumnInfo c in host.Fieldlist)
{ #>
	public <#= typeConvert(c.TypeName)#> get<#= c.ColumnName.ToString().Substring(0,1).ToUpper()#><#= c.ColumnName.ToString().Substring(1)#>() {
		return <#= c.ColumnName.ToString()#>;
	}
	public void set<#= c.ColumnName.ToString().Substring(0,1).ToUpper()#><#= c.ColumnName.ToString().Substring(1)#>(<#= typeConvert(c.TypeName)#> <#= c.ColumnName.ToString()#>) {
		this.<#= c.ColumnName.ToString()#> = <#= c.ColumnName.ToString()#>;
	}
<#}#>
}


<#+
//
private string getClassNameByTableName(string tname){
	string str2 = "";
    tname = tname.Replace("t_","");
	for (int i = 0; i < tname.Length; i++) {
        string temp =  tname.Substring(i, 1);
        if (temp == "_") {
            temp = tname.Substring(i+1, 1).ToUpper();
            i++;
        }
        if(i==0){
        	temp = temp.ToUpper();
        }
        str2 += temp;
   	}
   	return str2;
}

//mysql to java
//include varchar char longtext int bigint float double bit date real
//default type String
private string typeConvert(string type){
	string str2 = "String";
	if(type=="int"||type=="mediumint"||type=="integer"||type=="smallint"||type=="tinyint"){
		str2 = "Integer";
	}else if(type=="float"){
		str2 = "Float";
	}else if(type=="double"||type=="real"){
		str2 = "Double";
	}else if(type=="bigint"){
		str2 = "Long";
	}else if(type=="bit"){
		str2 = "Boolean";
	}else if(type=="date"||type=="datetime"||type=="timestamp"){
		str2 = "Date";
	}
   	return str2;
}

private string getDefaultValueByType(string type){
	string str2 = " = \"\"";
	if(type=="int"||type=="mediumint"||type=="integer"||type=="smallint"||type=="tinyint"){
		str2 = " = 0";
	}else if(type=="float"){
		str2 = " = 0f";
	}else if(type=="double"||type=="real"){
		str2 = " = 0d";
	}else if(type=="bigint"){
		str2 = " = 0l";
	}else if(type=="bit"){
		str2 = " = false";
	}else if(type=="date"||type=="datetime"||type=="timestamp"){
		str2 = " = new Date()";
	}
   	return str2;
}

Repository 

生成 几行代码而已啦 包含的Entity包名需要更改

<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
	TableHost host = (TableHost)(Host);
#>
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import com.avicsafety.webapp.entity.<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>; //请自行修改

@Repository
public interface <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>Repository extends JpaRepository<<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>, Long> {
	
}


<#+

private string getClassNameByTableName(string tname){
	string str2 = "";
    tname = tname.Replace("t_","");
	for (int i = 0; i < tname.Length; i++) {
        string temp =  tname.Substring(i, 1);
        if (temp == "_") {
            temp = tname.Substring(i+1, 1).ToUpper();
            i++;
        }
        if(i==0){
        	temp = temp.ToUpper();
        }
        str2 += temp;
   	}
   	return str2;
}

Service 层代码

 我写了个接口和类 来对应JPA常用方法

import java.io.Serializable;
import java.util.List;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;

/**
 * 基础的Service 接口 继承次接口 就有了 JPA了大部分方法
 * @author shili
 *
 */
public interface IService<T,ID extends Serializable> {
	/**
     * <p>
     * 插入一条记录 返回这个对象的实体
     * </p>
     *
     * @param entity 实体对象
     * @return T
     */
    T insert(T entity);

    /**
     * <p>
     * 插入多个实体
     * </p>
     *
     * @param entityList 实体对象列表
     * @return List
     */
    List<T> insert(List<T> entityList);



    /**
     * <p>
     * 更新操作 通过id
     * </p>
     * @param entity 实体对象列表
     * @param id
     * @return 这个对象
     */
    T update(T entity, ID id);
    
    /**
     * <p>
     * 更新操作 通过条件批量更新
     * </p>
     * @param 需要更新成啥样 这个里面是update 语句中 set部分
     * @param 给定的条件是一个实体 实体中的字段就是条件 这个是条件 不要弄反了 这个就是update 语句中 where部分
     * @return 影响的条目数
     */
    Integer update(T entity,T where);

    /**
     * <p>
     * 根据 ID 删除
     * </p>
     *
     * @param id 主键ID
     * @return boolean
     */
    void delete(ID id);
    
    /**
     * <p>
     * 根据 实体 删除 符合这个实体中字段条件的 都删除 
     * </p>
     *
     * @param 给定的条件是一个实体 实体中的字段就是条件
     * @return 删除的条目数
     */
    Integer deleteByBody(T where);

    /**
     * <p>
     *  通过条件批量删除
     * </p>
     *
     * @param id 主键ID
     * @return T
     */
    T findOne(ID id);

    /**
     * <p>
     * 查询（根据ID 批量查询）
     * </p>
     *
     * @param idList 主键ID列表
     * @return List<T>
     */
    List<T> findByIds(Iterable<ID> ids);
        
    /**
     * <p>
     * 列出所有
     * </p>
     *
     * @return List<T>
     */
    List<T> findAll();
    
    /**
     * <p>
     * 列出所有
     * </p>
     *
     * @return Page<T>
     */
    Page<T> findAll(Pageable pageable);

    /**
     * <p>
     * 查询（根据 Body 条件）
     * </p>
     *
     * @param Body 对象实体
     * @return List<T>
     */
    List<T> findByBody(T t);
    
    /**
     * <p>
     * 查询（根据 Body）
     * </p>
     *
     * @param Body 对象实体
     * @return Page<T>
     */
    Page<T> findByBody(T t,Pageable pageable);
    
    /**
     * <p>
     * 查询总记录数
     * </p>
     *
     * @param wrapper 实体对象
     * @return Long
     */
    Long count();


    /**
     * <p>
     * 根据 Body 条件，查询总记录数
     * </p>
     *
     * @param wrapper 实体对象
     * @return Long
     */
    Long count(T t);

}

实现

import java.io.Serializable;
import java.util.List;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Example;
import org.springframework.data.domain.Page;

/**

public class ServiceImpl<M extends JpaRepository<T,ID>,T,ID extends Serializable> implements IService<T,ID> {
	
    @Autowired
    protected M dao;

	@Override
	public T insert(T entity) {
		return dao.save(entity);
	}

	@Override
	public List<T> insert(List<T> entities) {

	}

	@Override

		T t= dao.findOne(id);
		BeanUtils.copyProperties(entity, t);

	}

	@Override

		dao.delete(id);;
	}

	@Override

	}

	@Override
	public Page<T> findAll(Pageable pageable) {
		return dao.findAll(pageable);
	}

	@Override
	public Long count() {
		return dao.count();
	}

	@Override
	public Long count(T t) {
		return dao.count(Example.of(t));
	}

	}

	@Override

	}

}

生成代码模板 就超级简单了 首先是接口

<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
	TableHost host = (TableHost)(Host);
#>

public interface <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>Service extends IService<<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>,Long> {

}

<#+

private string getClassNameByTableName(string tname){
	string str2 = "";
    tname = tname.Replace("t_","");
	for (int i = 0; i < tname.Length; i++) {
        string temp =  tname.Substring(i, 1);
        if (temp == "_") {
            temp = tname.Substring(i+1, 1).ToUpper();
            i++;
        }
        if(i==0){
        	temp = temp.ToUpper();
        }
        str2 += temp;
   	}
   	return str2;
}

#>

然后是实现

<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
	TableHost host = (TableHost)(Host);
#>

import org.springframework.stereotype.Service;


public class <#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>ServiceImpl extends ServiceImpl<<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>Repository,<#= getClassNameByTableName(host.GetModelClass(host.TableName)) #>,Long> implements IStockService{

}

<#+

private string getClassNameByTableName(string tname){
	string str2 = "";
    tname = tname.Replace("t_","");
	for (int i = 0; i < tname.Length; i++) {
        string temp =  tname.Substring(i, 1);
        if (temp == "_") {
            temp = tname.Substring(i+1, 1).ToUpper();
            i++;
        }
        if(i==0){
        	temp = temp.ToUpper();
        }
        str2 += temp;
   	}
   	return str2;
}

Controller 层

这里是 resful 风格 好吧 对付着用吧

<#@ template language="c#" HostSpecific="True" #>
<#@ output extension= ".java" #>
<#
	TableHost host = (TableHost)(Host);
#>

	public void delete(@PathVariable("id") Long id) {
		<#= getNameByTableName(host.GetModelClass(host.TableName)) #>Service.delete(id);
	}
	
}

<#+

private string getClassNameByTableName(string tname){
	string str2 = "";
    tname = tname.Replace("t_","");
	for (int i = 0; i < tname.Length; i++) {

前台使用Bootstrap + Vue  具体点应该说是AdminLET

html部分
