[SPRING] Spring JPA 트랜잭션 진행 중
SPRINGSpring JPA 트랜잭션 진행 중
나는 봄과 JPA에 익숙하지 않아 5 일을 낭비했고 인터넷 검색으로는 아무런 결과도 얻지 못했습니다. SQL SERVER에 개체를 저장하고 싶습니다. 연결은 정확하지만 .flush ()를 쓸 때 예외가 발생합니다.
이것은 내 jpaContext.xml입니다.

이것은 내 persistence.xml 파일입니다.
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="test" >
<class>com.misha.model.Table1</class>
</persistence-unit>
</persistence>
이것은 내 서비스 구현입니다.
@Service("manService")
public class SaveManImpl implements SaveMan {
//
@Autowired
private ManRepositoryImpl manRepo;
@Transactional
public Table1 save(Table1 table) {
manRepo.save(table);
return null;
}
}
마지막으로 저장소 구현 :
@Repository("manRepository")
public class ManRepositoryImpl implements ManRepository {
@PersistenceContext
private EntityManager em;
public Table1 save(Table1 table){
em.persist(table);
em.flush();
return table;
}
}
예외적으로 Spring Cant는 @Transactional annotation을 볼 수 있습니다. 주석 저장을 위의 저장 메소드 위에 올려 놓으려고했는데 아무런 결과도 없었습니다. 미리 감사드립니다.
내 컨트롤러에서 save 메서드를 호출합니다.
package com.misha.controllers;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.bind.annotation.RequestMapping;
import com.misha.model.Table1;
import com.misha.service.SaveMan;
@Controller
public class ManController {
@Autowired
SaveMan saveMan; // this is service interface
@RequestMapping(value="/test1")
public String saveMan(){
Table1 tab = new Table1();
tab.setName("name");
saveMan.save(tab);
return "saveMan";
}
}

해결법
-
==============================
1.두 개의 Spring 컨텍스트가 있습니다.
두 개의 Spring 컨텍스트가 있습니다.
문제는이 하위 컨텍스트에서 서비스 및 저장소 패키지도 검사한다는 것입니다. 따라서 각 서비스와 저장소의 두 인스턴스로 끝납니다.
따라서 컨트롤러에는 컨트롤러와 동일한 컨텍스트 (트랜잭션이 아닌 컨텍스트)에서 오는 서비스가 주입됩니다.
이를 확인하기 위해 빈의 생성자에 흔적을 추가하고 인스턴스화 된 횟수를 확인할 수 있습니다.
그리고이 문제를 피하기 위해 두 가지 해결책이 있습니다.

==============================
2.엔티티 관리자를 트랜잭션 관리자에 소개해야하므로 @Transactionalit을 사용하여 함수에 주석을 추가하면 풀에서 인스턴스가로드됩니다.

3.이야기를 짧게 만들려면 메서드 시작 부분에 @Transactional을 추가하십시오. 제 경우에는 그게 문제였습니다.
