mybatis-plus中Constants.WRAPPER的作用

Posted 2021-12-28 可小辉

List<DeptVo> list = deptMapper.queryList(page,queryWrapper);

@Select("SELECT\\n" +
           "\\tarticle.*, category. NAME category_name\\n" +
           "FROM\\n" +
           "\\tarticle\\n" +
           "LEFT JOIN category ON article.category_id = category.category_id\\n" +
           "$ew.customSqlSegment ")
List<DeptVo> queryList(Page<DeptVo> page,@Param(Constants.WRAPPER) QueryWrapper wrapper);

进行条件查询，减少了手动传参的复杂度和冗余度。
