There is no getter for property named 'siteAssociationMenus' in 'class com.czy.dto.accociation.response.SiteAssociationMenus'

1.检查实体类是否有get和set方法

2.字段名是否写错

3.加上@Param注解

4.如果用的springboot整合mybatis 注意@Param注解的包

springboot的是

org.springframework.data.repository.query.Param;

mybatis的是

org.apache.ibatis.annotations.Param;
