其中,经过我的测试,@Results注解内的代码不要也可以正常运行,但个人推荐加上,使之能够与po层一一对应
@Select({
""
})
@Results({
@Result(column = "id",property = "id",jdbcType = JdbcType.BIGINT),
@Result(column = "appreciation",property = "appreciation",jdbcType = JdbcType.BOOLEAN),
@Result(column = "commentabled",property = "commentabled",jdbcType = JdbcType.BOOLEAN),
