一.mybatis-config.xml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>
    <!--匯入properties-->
    <properties resource="db.properties"/>

    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="${driver}"/>
                <property name="url" value="${url}"/>
                <property name="username" value="${username}"/>
                <property name="password" value="${password}"/>
            </dataSource>
        </environment>
    </environments>
    <mappers>
        <!--dao的xml配置-->
        <mapper resource="com/lh/mapper/UserMapper.xml"/>
    </mappers>

    <!--使用class繫結介面,也就是使用註解開發-->
    <!--<mappers>
        <mapper class="com.lh.dao.UserDao"/>
    </mappers>-->

</configuration>
二.db.properties配置

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/mybatis?serverTimezone=UTC
username=root
password=123456
三.UserDao配置

//分頁查詢rowbounds分頁
List<User> getUserByRowBounds(Map<String,Object> map, RowBounds rowBounds);
四.UserMapper.xml配置

<?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">
<!--namespace寫的是dao的xml的地址-->
<mapper namespace="com.lh.dao.UserDao">
   
    <select id="getUserByRowBounds" resultType="com.lh.pojo.User">
        select  * from user
    </select>
</mapper>

五.測試方法

//分頁查詢rowbounds分頁
@Test
public void testUserRowBounds(){
    SqlSession session = MybatisUtils.getSession();
    UserDao mapper = session.getMapper(UserDao.class);
    HashMap<String, Object> map = new HashMap<String, Object>();
    map.put("username","");
    map.put("sex","");
    List<User> list = mapper.getUserByRowBounds(map, new RowBounds(0, 2));
    for (User user : list) {
        System.out.println(user);
    }
    session.close();
}
