Idea的maven工程的ssm整合

Idea的maven工程的ssm框架简单整合

1 数据库表格创建

CREATE TABLE `user` (   `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户ID',   `email` varchar(255) NOT NULL COMMENT '用户邮箱',   `password` varchar(255) NOT NULL COMMENT '用户密码',   `username` varchar(255) NOT NULL COMMENT '用户昵称',   `role` varchar(255) NOT NULL COMMENT '用户身份',   `status` int(1) NOT NULL COMMENT '用户状态',   `regTime` datetime NOT NULL COMMENT '注册时间',   `regIp` varchar(255) NOT NULL COMMENT '注册IP',   PRIMARY KEY (`id`),   UNIQUE KEY `email` (`email`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; INSERT INTO `user` VALUES ('1', '[email protected]', '123456', 'ruige', 'root', '0', '2017-03-28 09:40:31', '127.0.0.1'); SET FOREIGN_KEY_CHECKS=1;

2 环境配置

系统环境：ideaIU.2017.3编辑器、win7 X64系统、1.8版本的jdk、maven3.2.3。

Idea环境配置如下：

如图所示创建maven工程：   如下图所示，填写相应的项目名：   指定本地的maven项目，如下图所示：   确定项目名及文件目录无误之后，点击“Finish”按钮完成配置。

3 等待项目加载完成之后，将项目目录修改成如下图所示：

4 pom.xml文件的配置

7 mybatis配置

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"         "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration>     <!--别名配置-->     <typeAliases>         <!--指定义com.qhr.bean.User类的别名为user -->         <typeAlias type="com.qhr.entity.User" alias="user" />     </typeAliases>     <plugins>         <!-- com.github.pagehelper为PageHelper类所在包名 -->         <plugin interceptor="com.github.pagehelper.PageHelper">             <property name="dialect" value="mysql" />             <!-- 该参数默认为false -->             <!-- 设置为true时，会将RowBounds第一个参数offset当成pageNum页码使用 -->             <!-- 和startPage中的pageNum效果一样 -->             <property name="offsetAsPageNum" value="true" />             <!-- 该参数默认为false -->             <!-- 设置为true时，使用RowBounds分页会进行count查询 -->             <property name="rowBoundsWithCount" value="true" />             <!-- 设置为true时，如果pageSize=0或者RowBounds.limit = 0就会查询出全部的结果 -->             <!-- （相当于没有执行分页查询，但是返回结果仍然是Page类型） -->             <property name="pageSizeZero" value="true" />             <!-- 3.3.0版本可用 - 分页参数合理化，默认false禁用 -->             <!-- 启用合理化时，如果pageNum<1会查询第一页，如果pageNum>pages会查询最后一页 -->             <!-- 禁用合理化时，如果pageNum<1或pageNum>pages会返回空数据 -->             <property name="reasonable" value="true" />         </plugin>     </plugins>     <!--映射userModel.xml配置文件-->     <mappers>         <mapper resource="mapper/UserMapper.xml" />     </mappers> </configuration>

8 数据库配置

jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ruige jdbc.username=root jdbc.password=123456

9 创建User实体类

package com.qhr.entity; import java.util.Date; public class User {     private long id;     private String email;     private String password;     private String username;     private String role;     private int status;     private Date regTime;     private String regIp;

10 创建UserMapper.xml和UserDao类

UserMapper.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!-- 设置为IUserDao接口方法提供sql语句配置 --> <mapper namespace="com.qhr.dao.UserDao">     <select id="selectUser" resultType="user" parameterType="long">         SELECT * FROM user WHERE id = #{id}     </select> </mapper>

UserDao类

package com.qhr.dao; import com.qhr.entity.User; /**  * 持久化接口  */ public interface UserDao {     /**      * 根据id查询用户信息      * @param id      * @return      */     public User selectUser(long id); }

11 业务层接口UserService创建和UserServiceImpl实现类的创建：

UserService接口

package com.qhr.service; import com.qhr.entity.User; import org.springframework.stereotype.Service; /**  * 用户测试业务接口  */ @Service public interface UserService {     /**      * 根据id查询用户信息      * @param userId      * @return      */     public User getUserById(long userId); }

UserServiceImpl实现类：

package com.qhr.service.impl; import com.qhr.dao.UserDao; import com.qhr.entity.User; import com.qhr.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @Service public class UserServiceImpl implements UserService {     @Autowired     private UserDao userDao;     @Override     public User getUserById(long userId) {         return this.userDao.selectUser(userId);     } }

12 UserController创建

package com.qhr.controller; import com.qhr.entity.User; import com.qhr.service.UserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.HttpStatus; import org.springframework.http.ResponseEntity; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; /**  * 用户信息测试Controller  */ @Controller @RequestMapping("user") public class UserController {     @Autowired     private UserService userService;     /**      * 根据id获取用户信息      * @param id      * @return      */     @RequestMapping(value = "getUserInfoById",method = RequestMethod.POST)     @ResponseBody     public ResponseEntity<User> getUserInfoById(long id){         try {             User response = this.userService.getUserById(id);             return ResponseEntity.status(HttpStatus.CREATED).body(response);         } catch (Exception e){             e.printStackTrace();         }         return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body(null);     } }

13 测试环境配置

配置本地的tomcat7运行环境

 

14 开始测试

测试使用Postman的测试工具进行测试,当然也可以自己在前端写个form表单进行测试
