QueryWrapper 关联查询

QueryWrapper关联查询可以通过使用LambdaQueryWrapper或自定义SQL语句来实现。使用LambdaQueryWrapper可以使用.inSql()方法指定关联查询的条件，并将查询结果存储到缓存中，并将角色信息设置到用户对象中。另外，自定义SQL语句中也可以使用${ew.customSqlSegment}来指定关联查询的条件，并使用@Param("ew")注解将Wrapper对象传入。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
