我的文档结构

前面的实体类和dao和mapper可以看我前面的文章逆向工程实现，废话少说先上代码

实体类

package cn.com.demo.entity;public class Demo {    private Integer demoId;    private String demoName;    private String demoPassword;    public Integer getDemoId() {        return demoId;    }    public void setDemoId(Integer demoId) {        this.demoId = demoId;    }    public String getDemoName() {        return demoName;    }    public void setDemoName(String demoName) {        this.demoName = demoName == null ? null : demoName.trim();    }    public String getDemoPassword() {        return demoPassword;    }    public void setDemoPassword(String demoPassword) {        this.demoPassword = demoPassword == null ? null : demoPassword.trim();    }}

DAO

package cn.com.demo.dao;import cn.com.demo.entity.Demo;public interface DemoMapper {    int deleteByPrimaryKey(Integer demoId);    int insert(Demo record);    int insertSelective(Demo record);    Demo selectByPrimaryKey(Integer demoId);    int updateByPrimaryKeySelective(Demo record);    int updateByPrimaryKey(Demo record);}

mapper.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" ><mapper namespace="cn.com.demo.dao.DemoMapper" >  <resultMap id="BaseResultMap" type="cn.com.demo.entity.Demo" >    <id column="demo_id" property="demoId" jdbcType="INTEGER" />    <result column="demo_name" property="demoName" jdbcType="VARCHAR" />    <result column="demo_password" property="demoPassword" jdbcType="VARCHAR" />  </resultMap>  <sql id="Base_Column_List" >    demo_id, demo_name, demo_password  </sql>  <select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Integer" >    select     <include refid="Base_Column_List" />    from demo    where demo_id = #{demoId,jdbcType=INTEGER}  </select>  <delete id="deleteByPrimaryKey" parameterType="java.lang.Integer" >    delete from demo    where demo_id = #{demoId,jdbcType=INTEGER}  </delete>  <insert id="insert" parameterType="cn.com.demo.entity.Demo" >    insert into demo (demo_id, demo_name, demo_password      )    values (#{demoId,jdbcType=INTEGER}, #{demoName,jdbcType=VARCHAR}, #{demoPassword,jdbcType=VARCHAR}      )  </insert>  <insert id="insertSelective" parameterType="cn.com.demo.entity.Demo" keyProperty="demoId" useGeneratedKeys="true">    insert into demo    <trim prefix="(" suffix=")" suffixOverrides="," >      <if test="demoId != null" >        demo_id,      </if>      <if test="demoName != null" >        demo_name,      </if>      <if test="demoPassword != null" >        demo_password,      </if>    </trim>    <trim prefix="values (" suffix=")" suffixOverrides="," >      <if test="demoId != null" >        #{demoId,jdbcType=INTEGER},      </if>      <if test="demoName != null" >        #{demoName,jdbcType=VARCHAR},      </if>      <if test="demoPassword != null" >        #{demoPassword,jdbcType=VARCHAR},      </if>    </trim>  </insert>  <update id="updateByPrimaryKeySelective" parameterType="cn.com.demo.entity.Demo" >    update demo    <set >      <if test="demoName != null" >        demo_name = #{demoName,jdbcType=VARCHAR},      </if>      <if test="demoPassword != null" >        demo_password = #{demoPassword,jdbcType=VARCHAR},      </if>    </set>    where demo_id = #{demoId,jdbcType=INTEGER}  </update>  <update id="updateByPrimaryKey" parameterType="cn.com.demo.entity.Demo" >    update demo    set demo_name = #{demoName,jdbcType=VARCHAR},      demo_password = #{demoPassword,jdbcType=VARCHAR}    where demo_id = #{demoId,jdbcType=INTEGER}  </update></mapper>

service类

package cn.com.demo.service;import cn.com.demo.entity.Demo;public interface IDemoService{    int deleteByPrimaryKey(Integer demoId);    int insert(Demo record);    int insertSelective(Demo record);    Demo selectByPrimaryKey(Integer demoId);    int updateByPrimaryKeySelective(Demo record);    int updateByPrimaryKey(Demo record);}

service实现类

package cn.com.demo.service.impl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import cn.com.demo.dao.DemoMapper;import cn.com.demo.entity.Demo;import cn.com.demo.service.IDemoService;@Servicepublic class DemoServiceImpl implements IDemoService{@Autowiredprivate DemoMapper demoMapper;@Overridepublic int deleteByPrimaryKey(Integer demoId){// TODO Auto-generated method stubreturn demoMapper.deleteByPrimaryKey(demoId);}@Overridepublic int insert(Demo record){// TODO Auto-generated method stubreturn demoMapper.insert(record);}@Overridepublic int insertSelective(Demo record){// TODO Auto-generated method stubreturn demoMapper.insertSelective(record);}@Overridepublic Demo selectByPrimaryKey(Integer demoId){// TODO Auto-generated method stubreturn demoMapper.selectByPrimaryKey(demoId);}@Overridepublic int updateByPrimaryKeySelective(Demo record){// TODO Auto-generated method stubreturn demoMapper.updateByPrimaryKeySelective(record);}@Overridepublic int updateByPrimaryKey(Demo record){// TODO Auto-generated method stubreturn demoMapper.updateByPrimaryKey(record);}}

control类

package cn.com.demo.control;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import cn.com.demo.entity.Demo;import cn.com.demo.service.IDemoService;@Controller@RequestMapping("/test")public class DemoControl{@Autowiredprivate IDemoService demoService;@RequestMapping("/demo.html")public String demoTest(){Demo demo=new Demo();demo.setDemoName("username");demo.setDemoPassword("password");int id=demoService.insertSelective(demo);System.out.println(demo.getDemoId()+"qqqqqqqqqqqqqqqqq");return "demo";}}
