英文:
Spring JPA data, multiple methods with same functionality
问题
我正在使用Spring Data JPA与数据库交互，但是我遇到了一个问题：我不能用不同的命名实体多次定义相同的方法。
考虑以下代码：
class Repository {
@EntityGraph(value = UserEo.FULL, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findUserEoByEmail/*Full*/(String email);
@EntityGraph(value = UserEo.BRIEF, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findUserEoByEmail/*Brief*/(String email);
}
我希望能够拥有不同命名图的单独方法，但是在方法名称后添加附加信息会导致Spring出错。如何解决这个问题？
英文:
I am using spring data jpa to interact with a database, however I've come across a problem: I can't define the same method multiple times with different named entities.
Consider:
class Repository {
@EntityGraph(value = UserEo.FULL, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findUserEoByEmail/*Full*/(String email);
@EntityGraph(value = UserEo.BRIEF, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findUserEoByEmail/*Brief*/(String email);
}
I'd like to have separate methods with different named graphs, but adding additional information to the name of the methods breaks spring. How can this be solved?

正如注释所示，正确命名方法将不会“破坏Spring”。你可以这样做：
public interface Repository extends JpaRepository<UserEo, Long> {
@EntityGraph(value = UserEo.FULL, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findFullByEmail(String email);
@EntityGraph(value = UserEo.BRIEF, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findBriefByEmail(String email);
}
或者你可能想要将内容分割到两个不同的仓库中，如下所示：
public interface RepositoryFull extends JpaRepository<UserEo, Long> {
@EntityGraph(value = UserEo.FULL, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findByEmail(String email);
}
以及
public interface RepositoryBrief extends JpaRepository<UserEo, Long> {
@EntityGraph(value = UserEo.BRIEF, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findByEmail(String email);
}
英文:
As comment suggests naming the methods correctly will not "break Spring". You can have:
public interface Repository extends JpaRepository<UserEo, Long> {
@EntityGraph(value = UserEo.FULL, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findFullByEmail(String email);
@EntityGraph(value = UserEo.BRIEF, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findBriefByEmail(String email);
}
Or maybe you want to break stuff in two repositories, like:
public interface RepositoryFull extends JpaRepository<UserEo, Long> {
@EntityGraph(value = UserEo.FULL, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findByEmail(String email);
}
and
public interface RepositoryBrief extends JpaRepository<UserEo, Long> {
@EntityGraph(value = UserEo.BRIEF, type = EntityGraph.EntityGraphType.LOAD)
public Optional<UserEo> findByEmail(String email);
}
