項(xiàng)目地址:傳送門(mén)

一祝懂、搭建開(kāi)發(fā)環(huán)境

1.1、使用IDEA新建一個(gè)項(xiàng)目奶浦，項(xiàng)目結(jié)構(gòu)如下：

pox.xml主要分兩大部分藻烤，上面的10行-111行主要是為了添加項(xiàng)目jar包依賴(lài)，下面的114行-124行主要是為了集成generator插件(可以通過(guò)映射數(shù)據(jù)庫(kù)表字段生成實(shí)體類(lèi))爽雄；
添加pox.xml文件只有蝠检，在IDEA的右側(cè)打開(kāi)Maven Projects模塊，點(diǎn)擊左上方的刷新控件挚瘟，刷新整個(gè)項(xiàng)目叹谁。

1.2饲梭、右鍵項(xiàng)目，選擇open module setting本慕，點(diǎn)擊左上角的+符號(hào)排拷，選擇maven，添加generator插件

添加generator插件

二锅尘、創(chuàng)建數(shù)據(jù)庫(kù)和表(針對(duì)MySQL)

2.1 在MySQL數(shù)據(jù)庫(kù)中執(zhí)行如下SQL語(yǔ)句：

Create DATABASE spring4_mybatis3;
USE spring4_mybatis3;

DROP TABLE IF EXISTS user;
CREATE TABLE user (
  user_id char(32) NOT NULL,
  user_name varchar(30) DEFAULT NULL,
  user_birthday date DEFAULT NULL,
  user_salary double DEFAULT NULL,
  PRIMARY KEY (user_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

表結(jié)構(gòu)

三监氢、使用generator生成數(shù)據(jù)庫(kù)映射代碼

2.2 手動(dòng)創(chuàng)建【src/main/resources】、【src/main/java】藤违、【src/test/resources】浪腐、【src/test/java】這幾個(gè)source folder，如下圖所示：

目錄結(jié)構(gòu)

2.3 在main/resources中添加generatorConfig.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

    <context id="DB2Tables" targetRuntime="MyBatis3">

        </commentGenerator>
        <!-- 數(shù)據(jù)庫(kù)鏈接URL顿乒、用戶名议街、密碼 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/spring4_mybatis3" userId="root" password="123456">
            <!--<jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@localhost:1521:orcl" userId="msa" password="msa">-->
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- 生成實(shí)體類(lèi)的包名和位置，這里配置將生成的實(shí)體類(lèi)放在com.shi.domain這個(gè)包下 -->
        <javaModelGenerator targetPackage="com.shi.domain" targetProject="D:\Java\IdeaProjects\MyBatis\MyBatis_08\src\main\java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- 生成的SQL映射文件包名和位置璧榄，這里配置將生成的SQL映射文件放在com.shi.mapping這個(gè)包下 -->
        <sqlMapGenerator targetPackage="com.shi.mapping" targetProject="D:\Java\IdeaProjects\MyBatis\MyBatis_08\src\main\java">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置特漩，這里配置將生成的dao類(lèi)放在com.shi.dao這個(gè)包下 -->
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.shi.dao" targetProject="D:\Java\IdeaProjects\MyBatis\MyBatis_08\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        <!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
        <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
    </context>
</generatorConfiguration>

運(yùn)行之前配置好的generator_08插件，會(huì)在項(xiàng)目的java目錄中根據(jù)創(chuàng)建好的數(shù)據(jù)庫(kù)表生成MyBatis的表對(duì)應(yīng)的實(shí)體類(lèi):

實(shí)體類(lèi)

生成的代碼和映射文件一般都不用改骨杂，可以直接應(yīng)用到項(xiàng)目當(dāng)中涂身。下面我們看一眼由generator插件生成的代碼和映射文件：

• 生成的dao類(lèi)

生成的UserMapper是一個(gè)接口，里面定義了一些操作user表的增刪改查方法搓蚪。

package com.shi.dao;

import com.shi.domain.User;

public interface UserMapper {
    int deleteByPrimaryKey(String userId);

    int insert(User record);

    int insertSelective(User record);

    User selectByPrimaryKey(String userId);

    int updateByPrimaryKeySelective(User record);

    int updateByPrimaryKey(User record);
}

• 生成的實(shí)體類(lèi)

User類(lèi)是user表的對(duì)應(yīng)的實(shí)體類(lèi)蛤售，User類(lèi)中定義的屬性和user表中的字段一一對(duì)應(yīng)。

package com.shi.domain;

import java.util.Date;

public class User {
    private String userId;

    private String userName;

    private Date userBirthday;

    private Double userSalary;

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId == null ? null : userId.trim();
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName == null ? null : userName.trim();
    }

    public Date getUserBirthday() {
        return userBirthday;
    }

    public void setUserBirthday(Date userBirthday) {
        this.userBirthday = userBirthday;
    }

    public Double getUserSalary() {
        return userSalary;
    }

    public void setUserSalary(Double userSalary) {
        this.userSalary = userSalary;
    }
}

• 生成的SQL映射文件

<?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.shi.dao.UserMapper" >
  <resultMap id="BaseResultMap" type="com.shi.domain.User" >
    <id column="user_id" property="userId" jdbcType="CHAR" />
    <result column="user_name" property="userName" jdbcType="VARCHAR" />
    <result column="user_birthday" property="userBirthday" jdbcType="DATE" />
    <result column="user_salary" property="userSalary" jdbcType="DOUBLE" />
  </resultMap>
  <sql id="Base_Column_List" >
    user_id, user_name, user_birthday, user_salary
  </sql>
  <select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.String" >
    select 
    <include refid="Base_Column_List" />
    from user
    where user_id = #{userId,jdbcType=CHAR}
  </select>
  <delete id="deleteByPrimaryKey" parameterType="java.lang.String" >
    delete from user
    where user_id = #{userId,jdbcType=CHAR}
  </delete>
  <insert id="insert" parameterType="com.shi.domain.User" >
    insert into user (user_id, user_name, user_birthday, 
      user_salary)
    values (#{userId,jdbcType=CHAR}, #{userName,jdbcType=VARCHAR}, #{userBirthday,jdbcType=DATE}, 
      #{userSalary,jdbcType=DOUBLE})
  </insert>
  <insert id="insertSelective" parameterType="com.shi.domain.User" >
    insert into user
    <trim prefix="(" suffix=")" suffixOverrides="," >
      <if test="userId != null" >
        user_id,
      </if>
      <if test="userName != null" >
        user_name,
      </if>
      <if test="userBirthday != null" >
        user_birthday,
      </if>
      <if test="userSalary != null" >
        user_salary,
      </if>
    </trim>
    <trim prefix="values (" suffix=")" suffixOverrides="," >
      <if test="userId != null" >
        #{userId,jdbcType=CHAR},
      </if>
      <if test="userName != null" >
        #{userName,jdbcType=VARCHAR},
      </if>
      <if test="userBirthday != null" >
        #{userBirthday,jdbcType=DATE},
      </if>
      <if test="userSalary != null" >
        #{userSalary,jdbcType=DOUBLE},
      </if>
    </trim>
  </insert>
  <update id="updateByPrimaryKeySelective" parameterType="com.shi.domain.User" >
    update user
    <set >
      <if test="userName != null" >
        user_name = #{userName,jdbcType=VARCHAR},
      </if>
      <if test="userBirthday != null" >
        user_birthday = #{userBirthday,jdbcType=DATE},
      </if>
      <if test="userSalary != null" >
        user_salary = #{userSalary,jdbcType=DOUBLE},
      </if>
    </set>
    where user_id = #{userId,jdbcType=CHAR}
  </update>
  <update id="updateByPrimaryKey" parameterType="com.shi.domain.User" >
    update user
    set user_name = #{userName,jdbcType=VARCHAR},
      user_birthday = #{userBirthday,jdbcType=DATE},
      user_salary = #{userSalary,jdbcType=DOUBLE}
    where user_id = #{userId,jdbcType=CHAR}
  </update>
</mapper>

UserMapper.xml這個(gè)文件的內(nèi)容是編寫(xiě)操作user表的SQL語(yǔ)句妒潭，重點(diǎn)說(shuō)一下UserMapper.xml配置中需要注意的幾個(gè)小細(xì)節(jié)問(wèn)題：

1悴能、UserMapper.xml的<mapper>標(biāo)簽的namespace必須是UserMapper接口的全類(lèi)名，<mapper namespace="com.shi.dao.UserMapper" >

2雳灾、UserMapper.xml的定義操作數(shù)據(jù)庫(kù)的<select><delete><update><insert>這些標(biāo)簽的id屬性的值必須和UserMapper接口定義的方法名一致漠酿，如下圖所示：

對(duì)應(yīng)關(guān)系

四、Spring與MyBatis整合

4.1佑女、添加Service對(duì)象

1记靡、在src/main/java目錄下創(chuàng)建一個(gè)com.shi.service包，然后在com.shi.service包創(chuàng)建一個(gè)UserServiceI接口团驱，如下所示：

package com.shi.service;


import com.shi.domain.User;

public interface UserServiceI {

    /**
     * 添加用戶
     * @param user
     */
    void addUser(User user);
    
    /**
     * 根據(jù)用戶id獲取用戶
     * @param userId
     * @return
     */
    User getUserById(String userId);
}

2摸吠、在src/main/java目錄下創(chuàng)建一個(gè)com.shi.service.impl包，然后在com.shi.service.impl包創(chuàng)建一個(gè)針對(duì)UserServiceI接口的實(shí)現(xiàn)類(lèi)：UserServiceImpl嚎花，如下所示：

package com.shi.service.impl;

import com.shi.dao.UserMapper;
import com.shi.domain.User;
import com.shi.service.UserServiceI;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @author AFinalStone
 * 使用@Service注解將UserServiceImpl類(lèi)標(biāo)注為一個(gè)service
 * service的id是userService
 */
@Service("userService")
public class UserServiceImpl implements UserServiceI {

    /**
     * 使用@Autowired注解標(biāo)注userMapper變量寸痢，
     * 當(dāng)需要使用UserMapper時(shí)，Spring就會(huì)自動(dòng)注入U(xiǎn)serMapper
     */
    @Autowired
    private UserMapper userMapper;//注入dao

    public void addUser(User user) {
        userMapper.insert(user);
    }

    public User getUserById(String userId) {
        return userMapper.selectByPrimaryKey(userId);
    }
}

4.2紊选、編寫(xiě)相關(guān)配置文件

1啼止、dbconfig.properties

在src/main/resources目錄下創(chuàng)建一個(gè)dbconfig.properties文件道逗，用于編寫(xiě)連接MySQL數(shù)據(jù)庫(kù)的相關(guān)信息，dbconfig.properties的內(nèi)容如下：

driverClassName=com.mysql.jdbc.Driver
validationQuery=SELECT 1
jdbc_url=jdbc:mysql://localhost:3306/spring4_mybatis3?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc_username=root
jdbc_password=123456

2献烦、spring.xml(spring框架的配置文件)

在src/main/resources目錄下創(chuàng)建一個(gè)spring.xml文件滓窍，spring.xml文件就是針對(duì)Spring框架編寫(xiě)的核心配置文件，我們的spring.xml文件的配置非常簡(jiǎn)單巩那，就兩個(gè)配置吏夯。
spring.xml的內(nèi)容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- 引入dbconfig.properties屬性文件 -->
    <context:property-placeholder location="classpath:dbconfig.properties" />
    <!-- 自動(dòng)掃描(自動(dòng)注入)，com.shi.service這個(gè)包以及它的子包的所有使用@Service注解標(biāo)注的類(lèi) -->
    <context:component-scan base-package="com.shi.service" />
</beans>

3即横、spring-mybatis.xml(spring與mybatis整合的配置文件)

在src/main/resources目錄下創(chuàng)建一個(gè)spring-mybatis.xml文件噪生，spring-mybatis.xml文件就是針對(duì)Spring框架與Mybatis框架整合編寫(xiě)的配置文件，spring-mybatis.xml的內(nèi)容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="
