介面類

List<User> selectByParameter(String value);

實現方式一

• 介面類的實現

  <select id="selectByParameter" resultType="User">
     select * from mybatistest where name like #{value};
  </select>

• 測試

  public static void selectByParameter(){
    SqlSession sqlSession = MybatisUtils.getSqlSession();
  ​
    UserMapper userMapper = sqlSession.getMapper(UserMapper.class);
   
    List<User> userList = userMapper.selectByParameter("%小%");
    for (User user : userList) {
      System.out.println(user);
     }
  ​
    sqlSession.close();
  }
