spring boot之mybatis

  spring boot不再累述。简单说一下就spring boot与mybatis的整合过程。
  环境：java8
  IDE：idea
  demo git地址：https://github.com/yhan219/shop，由于demo一直在更新，请自行回退。

依赖：

<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter</artifactId>
	<version>1.1.1</version>
</dependency>

gradle请自行替换。

yml中数据源配置：

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8
    username: root
    password: 

yml中mybatis配置文件：

mybatis:
  typeAliasesPackage: com.thunisoft.domain
  mapper-locations: classpath:mapper/*.xml

添加事务：在@SpringBootApplication下添加@EnableTransactionManagement

简单的整合到此结束。

以demo为例简单说一下使用：

实体类：

package com.yhan219.domain;

import java.io.Serializable;

/**
 * Created by yhan219 on 2017/1/6.
 */
public class User implements Serializable {

    private String id;

    private String username;

    private String password;

    private String tel;

    private Integer role;

    public void setPassword(String password) {
        this.password = password;
    }

    public String getPassword() {
        return password;
    }

    public void setTel(String tel) {
        this.tel = tel;
    }

    public String getTel() {
        return tel;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getUsername() {
        return username;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getId() {
        return id;
    }

    public void setRole(Integer role) {
        this.role = role;
    }

    public Integer getRole() {
        return role;
    }

}

mapper：

package com.yhan219.repository;

import com.yhan219.domain.User;
import org.apache.ibatis.annotations.Mapper;

import java.util.List;

/**
 * Created by yhan219 on 2017/1/7.
 */
@Mapper
public interface UserMapper {

    int save(User user);

    User selectById(String id);

    int updateById(User user);

    int deleteById(String id);

    List<User> queryAll();

}

<?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="com.yhan219.repository.UserMapper" >
    <insert id="save" parameterType="com.yhan219.domain.User">
        insert into t_user(id,username,password,tel) values(#{id,jdbcType=VARCHAR},#{username,jdbcType=VARCHAR},#{password,jdbcType=VARCHAR},#{tel,jdbcType=VARCHAR})
    </insert>
    <select id="selectById" resultType="com.yhan219.domain.User">
        select * from t_user where id = #{id,jdbcType=VARCHAR}
    </select>
    <update id="updateById" parameterType="com.yhan219.domain.User">
        update t_user set
        username = #{username,jdbcType=VARCHAR} ,
        password = #{password,jdbcType=VARCHAR} ,
        tel = #{tel,jdbcType=VARCHAR},
        role = #{role,jdbcType=INTEGER}
        where id = #{id,jdbcType=VARCHAR}
    </update>
    <delete id="deleteById">
        delete from t_user where id = #{id,jdbcType=VARCHAR}
    </delete>
    <select id="queryAll" resultType="com.yhan219.domain.User">
        select * from t_user
    </select>
</mapper>

  使用方法同一般mybatis通常来说。spring boot是简化配置，并不简化代码。service和controller请看demo源码。
