spring-boot - findAll() 上的 @NamedEntityGraphs

Question

我在我的应用程序中使用 @NamedEntityGraph

@NamedEntityGraphs({
    @NamedEntityGraph(name = "graph.Employee.assignments", attributeNodes = @NamedAttributeNode("assignmentProjectEmployeeSet")),
    @NamedEntityGraph(name = "graph.Employee.absences", attributeNodes = @NamedAttributeNode("absences"))
})enter code here`public class Employee {

当我通过在存储库上使用它时

@EntityGraph(value = "graph.Employee.assignments", type = EntityGraph.EntityGraphType.FETCH)
List<Employee> findAll();

我得到了预期的所有结果。但是对于不同的情况，我需要多个版本的 findAll()。就像是

@EntityGraph(value = "graph.Employee.assignments", type = EntityGraph.EntityGraphType.FETCH)
List<Employee> findAllWithAssignments();

@EntityGraph(value = "graph.Employee.absences", type = EntityGraph.EntityGraphType.FETCH)
List<Employee> findAllWithAbsences();

但是，如果我尝试在存储库中定义新方法名称，则会收到应用程序上下文错误，因为 Spring 无法解析该方法名称。

有没有可能得到这样的方法？

谢谢

添加 @Query 您的方法将选择所有 Employee s:

@Query("select e from Employee e")
@EntityGraph(value = "graph.Employee.assignments", type = EntityGraph.EntityGraphType.FETCH)
List<Employee> findAllWithAssignments();

@Query("select e from Employee e")
@EntityGraph(value = "graph.Employee.absences", type = EntityGraph.EntityGraphType.FETCH)
List<Employee> findAllWithAbsences();

或者使用方法名称 findAllWithAssignmentsBy findAllWithAbsencesBy也应该工作
