使用Spring@Procedure调用StoredProcedure而不绑定到表
我想知道是否可以调用存储过程而不必将其绑定到表/模型 在我的例子中,数据库中有一个发送邮件的存储过程。我想从春季开始称之为:使用Spring@Procedure调用StoredProcedure而不绑定到表,spring,stored-procedures,spring-data-jpa,spring-repositories,Spring,Stored Procedures,Spring Data Jpa,Spring Repositories,我想知道是否可以调用存储过程而不必将其绑定到表/模型 在我的例子中,数据库中有一个发送邮件的存储过程。我想从春季开始称之为: public interface SendEmail extends org.springframework.data.repository.Repository<Email, Long> { @Procedure(procedureName = "send_email") void sendEmail(String sender, Strin
public interface SendEmail extends org.springframework.data.repository.Repository<Email, Long> {
@Procedure(procedureName = "send_email")
void sendEmail(String sender, String recipient, String ccRecipient, String subject, String message);
}
然后我得到以下错误:

作为结论,我需要有一个名为Email
的模型,该模型映射到数据库中的一个表,以便上面的工作。为什么会这样
(我试图用
@Repositories
和@Component
对接口进行注释)
基于存储库的域驱动设计概念:一个行为类似于聚合根集合但内容存储在某个持久存储中的对象。因此,存储库
需要知道它负责的聚合根以及它的id类型,以便在存储中找到它
对于JPA存储库,这意味着聚合必须是JPA映射的实体。当然,基于POJO实体并由存储过程支持实现存储库是可能的。这个想法没有什么错,只是它不是一个常见的用例,而且对于您的用例来说,可能有点过头了
如果只想调用存储过程,最好使用一个简单的Springbean和一个
JdbcTemplate
,您可以这样使用用户:
@Repository
public class RepositoryClass implements DataRepository {
@PersistenceContext
private EntityManager em;
}
谢谢你的回答。我确实提出了一个解决方案,我@Autowire一个EntityManager,然后生成一个StoredProcedure对象:StoredProcedureStoredProcedure=EntityManager.CreateStoreProcedureQuery(“发送电子邮件”);这也很好…我知道这已经很晚了,但是你能分享一下你是如何在github上完成的吗,这会有帮助,或者是材料吗?是的。。。这个答案的一些代码会很有帮助。事实上,这充其量只是间接的帮助。
