java - spring data jpa @query 支持投影吗？

Question

spring boot版本:1.5.10，spring data jpa 1.11.10

在我的 MyEntityRespostory 中:

 Page<MyEntityPro> findByName(String name,Pageable pageable ) // working

 @("select e from MyEntity e")
 Page<MyEntity> search1(Pageable pageable) // working

 @("select e from MyEntity e")
 Page<MyEntityPro> search2(Pageable pageable) //error-No aliases found in result tuple! Make sure your query defines aliase

我搜索错误并发现: https://jira.spring.io/browse/DATAJPA-885

Answer 1

如果使用上层查询关键字，就会导致问题。

....
@query("SELECT e FROM MyEntity") // bug
......
@query("select e from MyEntity") // working
...
