【MyBatis】学习笔记09：动态设置表名

/**
     * 获取表所有数据
     * @param tableName 表名
     * @return List<User>
     */
    List<User> getAll(@Param("tableName") String tableName);

<!--    List<User> getAll(@Param("tableName") String tableName);-->
    <select id="getAll" resultType="User">
        select * from ${tableName}
    </select>

@Test
    public void testGetAll(){
        SqlSession sqlSession = SqlSessionUtils.getSqlSession();
        SQLMapper mapper = sqlSession.getMapper(SQLMapper.class);
        List<User> list = mapper.getAll("t_users");
        System.out.println(list);
    }
