Enums QueryDSL，将枚举从JPASQLQuery投影到DTO时参数类型非法
我们必须使用JPASQLQueries处理在任意列和子查询上具有连接的复杂查询。一个这样的查询从数据库返回一个字符串，并应将其投影到DTO的枚举中。当试图为该特定值调用DTO上的setter时，此映射因“非法参数类型”而失败。Enums QueryDSL，将枚举从JPASQLQuery投影到DTO时参数类型非法,enums,querydsl,native-sql,Enums,Querydsl,Native Sql,我们必须使用JPASQLQueries处理在任意列和子查询上具有连接的复杂查询。一个这样的查询从数据库返回一个字符串，并应将其投影到DTO的枚举中。当试图为该特定值调用DTO上的setter时，此映射因“非法参数类型”而失败。 映射到与DTO工作的结构相同的实体 这是我使用的查询： final QOrderHeader orderHeader = QOrderHeader.orderHeader; QOrderHeader orderGroup = new QOrderHeade
