Spring Jpa 存储过程中有多个输出参数 - 异常 "No property found for type"

Question

我调用 oracle 存储过程使用 spring-data-jpa:2.1.9.RELEASE (Spring boot 2.1.6 RELEASE)

程序：

procedure proc(data in varchar2, res1 out number, res2 out number)
begin
  insert into table (id, data) values (abc.hibernate_sequence.nextval, data)
  returning id into res1;
  res2 := id*5;
end proc;

实体

@Entity
@Table(name = "table", schema = "abc')
@NamedStoredProcedureQuery(name = "testName", procedureName = "proc", parameters = {
    @StoredProcedureParameter(mode = ParameterMode.IN, name = "data", type = String.class),
    @StoredProcedureParameter(mode = ParameterMode.OUT, name = "res1", type = Long.class),
    @StoredProcedureParameter(mode = ParameterMode.OUT, name = "res2", type = Long.class) 
})
public class testEntity { ... }

存储库

@Repository
public interface TestEntityRepository extends JpaRepository<TestEntity, Long> {

  @Transactional
  @Procedure(name = "testName")
  Map<String, Long> procedure(@Param("data") String data);
}

当我开始申请时：

IllegalArgumentException: Failed to create query for method public abstract java.util.Map TestEntityRepository.procedure(java.lang.String)! 
No property procedure found for type TestEntity

如果我使用只有 1 个输出参数的存储过程，一切都很好。

在spring-data-jpa:2.2.0.RELEASE.[之前使用@Procedure注解只能获取一个out参数。 =12=]

如果您不能更改依赖版本，那么您将不得不使用以下代码使其工作：

StoredProcedureQuery query = this.em.createNamedStoredProcedureQuery("testName");
query.setParameter("data", "data_value");
query.execute();
Long sum = (Long) query.getOutputParameterValue("res1");
Long sum = (Long) query.getOutputParameterValue("res2");
