MyBatis學習

 初次接觸

MyBatis是一種輕量級的ORM框架，相對於Hibernate來說比較簡單易用，對於較小的系統或者對於SQL語句有獨特愛好的朋友可以使用MyBatis進行開發。網上大多是直接照抄MyBatis官網提供的docs例子進行粘貼，具體能不能用還不得而知。下面以一個例子來介紹MyBatis的基本使用。

一、建立數據庫表

創建用戶表：

DROP TABLE IF EXISTS user;
CREATE TABLE user (
  username varchar(50) NOT NULL,
  password varchar(50) DEFAULT NULL,
  address varchar(50) DEFAULT NULL,
  age varchar(5) DEFAULT NULL,
  sex varchar(2) DEFAULT NULL,
  PRIMARY KEY (username)
)

二、建立對應的DTO對象

public class UserDto implements java.io.Serializable {
    private static final long serialVersionUID = 1L;
    private String username;
    private String password;
    private String address;
    private String age;
    private String sex;

    public UserDto() {
    }

    public UserDto(String username, String password, String address, String age, String sex) {
        this.username = username;
        this.password = password;
        this.address = address;
        this.age = age;
        this.sex = sex;
    }

    public String getUsername() {
        return this.username;
    }

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

    public String getPassword() {
        return this.password;
    }

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

    public String getAddress() {
        return this.address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getAge() {
        return this.age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public String getSex() {
        return this.sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }
}

三、建立MyBatis系統配置文件[mybatis-config.xml]

<?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>
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC" />
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver" />
                <property name="url" value="jdbc:mysql://127.0.0.1:3306/test" />
                <property name="username" value="test" />
                <property name="password" value="test" />
            </dataSource>
        </environment>
    </environments>
    <mappers>
        <mapper resource="UserMapper.xml" />
    </mappers>
</configuration>

四、建立user表的映射文件(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">
<mapper namespace="com.mapper.UserMapper">
  <select id="selectUser" parameterType="String" resultType="com.dto.UserDto">
    select * from user where username = #{username}
  </select>
</mapper>

五、建立映射接口類（如果sql語句寫在映射的配置XML文件，這一步可以不用）

package com.mapper;

import org.apache.ibatis.annotations.Select;

import com.dto.UserDto;

public interface UserMapper {
    @Select("select * from user where username = #{username}")
    public UserDto seleteUser(String username);

}

六、建立測試類

package com.test;


import java.io.InputStream;

import org.apache.ibatis.binding.MapperRegistry;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.Configuration;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Before;
import org.junit.Test;

import com.dto.UserDto;
import com.mapper.UserMapper;

public class UserTest {
    SqlSessionFactory sqlSessionFactory = null;
    @Before
    public void setUp() throws Exception {
        String resource = "mybatis-config.xml";
        InputStream inputStream = Resources.getResourceAsStream(resource);
        sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        Configuration configuration = sqlSessionFactory.getConfiguration();
        MapperRegistry mapperRegistry = configuration.getMapperRegistry();
        System.out.println(mapperRegistry.getMappers());

    }
    @Test
    public void seleteXMLTest(){
        SqlSession session = sqlSessionFactory.openSession();
        try {
          UserDto userDto = (UserDto) session.selectOne("com.mapper.UserMapper.selectUser", "xyz");
          System.out.println(userDto.getUsername());
          System.out.println(userDto.getPassword());
          System.out.println(userDto.getAddress());
          System.out.println(userDto.getAge());
          System.out.println(userDto.getSex());
        } finally {
          session.close();
        }
    }
    @Test
    public void seleteAnnotaionTest(){
        SqlSession session = sqlSessionFactory.openSession();
        try {
            UserMapper userMapper = session.getMapper(UserMapper.class);
            UserDto userDto = userMapper.seleteUser("xyz");
            System.out.println(userDto.getUsername());
            System.out.println(userDto.getPassword());
            System.out.println(userDto.getAddress());
            System.out.println(userDto.getAge());
            System.out.println(userDto.getSex());
        } finally {
            session.close();
        }
    }

}

完成簡單的增、刪、改、查操作

使用MyBatis進行數據庫增刪改查的操作是很簡單的，主要在配置文件中寫好相應的SQL語句，然後在程序中進行調用即可。具體代碼如下：

一、映射配置文件

<?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.mapper.UserMapper">
  <select id="selectUser" parameterType="String" resultType="com.dto.UserDto">
    select * from user where username = #{username}
  </select>
  <select id="selectAllUser" resultType="com.dto.UserDto">
    select * from user
  </select>
  <insert id="insertUser" parameterType="com.dto.UserDto">
    insert into user(username,password,address,age,sex)
    values (#{username},#{password},#{address},#{age},#{sex})
  </insert>
  <update id="updateUser" parameterType="com.dto.UserDto">
    update user set password=#{password},address=#{address},age=#{age},sex=#{sex}
    where username=#{username}
  </update>
  <delete id="deleteUser" parameterType="String">
    delete from user where username=#{username}
  </delete>
  <delete id="deleteAllUser">
    delete from user
  </delete>
</mapper>

二、測試類

package com.test;

import java.io.InputStream;
import java.util.List;

import org.apache.ibatis.binding.MapperRegistry;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.Configuration;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Before;
import org.junit.Test;

import com.dto.UserDto;
import com.mapper.UserMapper;

public class UserTest{
    SqlSessionFactory sqlSessionFactory = null;

    @Before
    public void setUp() throws Exception {
        String resource = "mybatis-config.xml";
        InputStream inputStream = Resources.getResourceAsStream(resource);
        sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
    }

    @Test
    public void seleteXMLTest() {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            UserDto userDto = (UserDto) session.selectOne("com.mapper.UserMapper.selectUser", "test");
            System.out.println(userDto.getUsername()+"\t"+userDto.getPassword()+"\t"+userDto.getAddress()+"\t"+userDto.getAge()+"\t"+userDto.getSex());
        } finally {
            session.close();
        }
    }
    @Test
    public void seleteAllXMLTest() {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            List<UserDto> list = session.selectList("com.mapper.UserMapper.selectAllUser");
            for(UserDto userDto : list){
                System.out.println(userDto.getUsername()+"\t"+userDto.getPassword()+"\t"+userDto.getAddress()+"\t"+userDto.getAge()+"\t"+userDto.getSex());
            }
        } finally {
            session.close();
        }
    }

    @Test
    public void seleteAnnotaionTest() {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            UserMapper userMapper = session.getMapper(UserMapper.class);
            UserDto userDto = userMapper.seleteUser("test");
            System.out.println(userDto.getUsername()+"\t"+userDto.getPassword()+"\t"+userDto.getAddress()+"\t"+userDto.getAge()+"\t"+userDto.getSex());
        } finally {
            session.close();
        }
    }

    @Test
    public void insertXMLTest() {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            UserDto userDto = new UserDto();
            userDto.setUsername("test");
            userDto.setPassword("test");
            userDto.setAddress("測試地址......");
            userDto.setAge("30");
            userDto.setSex("男");
            int res = session.insert("com.mapper.UserMapper.insertUser", userDto);
            session.commit();
            System.out.println("res = " + res);
        } finally {
            session.close();
        }
    }
    @Test
    public void updateXMLTest() {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            UserDto userDto = new UserDto();
            userDto.setUsername("test");
            userDto.setPassword("111111");
            userDto.setAddress("地址");
            userDto.setAge("33");
            userDto.setSex("女");
            int res = session.update("com.mapper.UserMapper.updateUser", userDto);
            session.commit();
            System.out.println("res = " + res);
        } finally {
            session.close();
        }
    }
    @Test
    public void deleteXMLTest() {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            int res = session.delete("com.mapper.UserMapper.deleteUser", "test");
            session.commit();
            System.out.println("res = " + res);
        } finally {
            session.close();
        }
    }
    @Test
    public void deleteAllXMLTest() {
        SqlSession session = sqlSessionFactory.openSession();
        try {
            int res = session.delete("com.mapper.UserMapper.deleteAllUser");
            session.commit();
            System.out.println("res = " + res);
        } finally {
            session.close();
        }
    }
}

注意：在更新操作完成之後需要調用session.commit()方法，不然數據不會更新到數據庫中。

使用SqlBuilder生成SQL語句

在MyBatis的映射配置文件中寫sql語句有時候很方便，但是對於有大量字段的表結構卻不太簡單，幸好MyBatis提供的有SqlBuilder工具類，可以生成相應的SQL語句，如下例程：

package com.utils;

import org.apache.ibatis.jdbc.SqlBuilder;

public class MyBatisUtils extends SqlBuilder {
    public String selectUserSql() {
        BEGIN();
        SELECT("*");
        FROM("UserDto");
        return SQL();
    }

    public String deleteUserSql() {
        BEGIN();
        DELETE_FROM("UserDto");
        WHERE("username = #{username}");
        return SQL();
    }

    public String insertUserSql() {
        BEGIN();
        INSERT_INTO("UserDto");
        VALUES("username", "#{username}");
        VALUES("password", "#{password}");
        VALUES("address", "#{address}");
        VALUES("age", "#{age}");
        VALUES("sex", "#{sex}");
        return SQL();
    }

    public String updateUserSql() {
        BEGIN();
        UPDATE("UserDto");
        SET("password = #{password}");
        WHERE("username = #{username}");
        return SQL();
    }

    public static void main(String[] args) {
        MyBatisUtils myBatisUtils = new MyBatisUtils();
        System.out.println("查詢 = " + myBatisUtils.selectUserSql());
        System.out.println("刪除 = " + myBatisUtils.deleteUserSql());
        System.out.println("插入 = " + myBatisUtils.insertUserSql());
        System.out.println("更新 = " + myBatisUtils.updateUserSql());
    }
}

使用MyBatis_Generator生成Dto、Dao、Mapping

由於MyBatis屬於一種半自動的ORM框架，所以主要的工作將是書寫Mapping映射文件，但是由於手寫映射文件很容易出錯，所以查資料發現有現成的工具可以自動生成底層模型類、Dao接口類甚至Mapping映射文件。

一、建立表結構

CREATE TABLE `user` (
  `id` varchar(50) NOT NULL,
  `username` varchar(18) CHARACTER SET utf8 COLLATE utf8_bin DEFAULT NULL,
  `password` varchar(18) DEFAULT NULL,
  `email` varchar(50) DEFAULT NULL,
  `name` varchar(18) DEFAULT NULL,
  `sex` varchar(2) DEFAULT NULL,
  `birthday` varchar(50) DEFAULT NULL,
  `address` varchar(500) DEFAULT NULL,
  `tel` varchar(18) DEFAULT NULL,
  `qq` varchar(18) DEFAULT NULL,
  `image` varchar(50) DEFAULT NULL,
  `sfjh` varchar(1) DEFAULT NULL,
  `sfzx` varchar(1) DEFAULT NULL,
  `sfhf` varchar(1) DEFAULT NULL,
  `sfpl` varchar(1) DEFAULT NULL,
  `sffx` varchar(1) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf-8;

二、下載mybatis-generator-core

進入：http://code.google.com/p/mybatis/

選擇Downloads，再選擇MyBatis Generator Tool下載即可。

三、生成配置文件

新建一個空的XML配置文件，名稱可以隨便取，這裏以generatorConfig.xml爲名。最好將這個文件放在下載後的lib目錄中，如圖：

其中mysql的驅動可以隨便放在非中文路徑的地方，這裏爲了方便就放在lib目錄下。

自動生成最重要的就是配置文件的書寫，現在就開始介紹generatorConfig.xml這個文件的具體內容：

<?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">
<generatorConfiguration>
<!-- 數據庫驅動-->
    <classPathEntry  location="mysql-connector-java-5.0.6-bin.jar"/>
    <context id="DB2Tables"  targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自動生成的註釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>
        <!--數據庫鏈接URL，用戶名、密碼 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost/test" userId="test" password="test">
        </jdbcConnection>
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>
        <!-- 生成模型的包名和位置-->
        <javaModelGenerator targetPackage="test.model" targetProject="src">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>
        <!-- 生成映射文件的包名和位置-->
        <sqlMapGenerator targetPackage="test.mapping" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置-->
        <javaClientGenerator type="XMLMAPPER" targetPackage="test.dao" targetProject="src">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>
        <!-- 要生成哪些表-->
        <table tableName="about" domainObjectName="AboutDto" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="user" domainObjectName="UserDto" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
        <table tableName="syslogs" domainObjectName="SyslogsDto" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

1、其中需要注意的有數據庫驅動、數據庫URL、用戶名、密碼、生成模型的包名和位置、生成映射文件的包名和位置、生成DAO的包名和位置以及最後需要生成的表名和對應的類名。

四、運行

需要通過CMD命令行方式來運行，首先可以先準備一個運行的腳本，這裏使用的腳本是：java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

需要注意的是：mybatis-generator-core-1.3.2.jar爲下載的對應版本的jar，generatorConfig.xml 爲配置文件名，如果不爲這個可以在這裏進行修改。

啓動cmd進入到“F:\soft\mybatis-generator-core-1.3.2\lib”這個目錄下，如圖：

生成成功後進到src目錄下，可以看到已經生成了對應的model、dao、mapping，如圖：

下面可以看看生成後的UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
