mybatis

    String resource = "mybatis-config.xml";
        InputStream inputStream  = getResourceAsStream(resource);

        SqlSessionFactory sqlSessionFactory =   new SqlSessionFactoryBuilder().build(inputStream);
        SqlSession sqlSession = sqlSessionFactory.openSession();
        Map<String,String> map = new HashMap<String,String>();
        map.put("id", "029c987e4a9745b38aa65e46d8c77a01");
        User user = sqlSession.selectOne("com.mytest.UserMapper.UserMapper.selectUser", map);


  User userinsert = new User("11101", "222", "333");
  int a = sqlSession.insert("com.mytest.UserMapper.UserMapper.insertUser", userinsert);

 sqlSession.commit();
 sqlSession.close();

　　把mybatis 的配置文件放到  src/main/resources 下，文件内容如下：

<?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://192.168.1.193:3306/test?characterEncoding=utf8"/>
                <property name="username" value="root"/>
                <property name="password" value="111"/>
            </dataSource>
        </environment>
    </environments>
    <mappers>
        <mapper resource="com/mytest/UserMapper/UserMapper.xml"/>
    </mappers>
</configuration>

　　

test 是数据库名，
