mybatisPlus实现倒序拼接字符串

倒序拼接字符串

@ApiOperation("分页查询")
   @GetMapping(value = "/list")
   public ActionResult<Map<String, Object>> list(@RequestParam Map<String, Object> params) {
       List<String> list = Arrays.asList(new String[]{"create_time"});
       return new ActionResult(StatusCode.SUCCESS, iUmsMemberService.selectPage(new Query<>(params),
               new EntityWrapper<UmsMember>().eq("deleted", 0).orderDesc(list)));
   }

等同于

SELECT id AS id,member_level_id AS memberLevelId,username, FROM ums_member WHERE (deleted = 0) ORDER BY create_time DESC LIMIT 0,5

把sql用字符串拼接好后直接取出使用

/**
     * 查询sql
     * @param sql
     * @return
     */
    Object aa(@Param(value = "sql") String sql);

 <select id="aa" resultType="Object">
        ${sql}
    </select>
