[SPRING] @Autowired와 함께 @Transaction 주석 사용 - 봄

@Autowired와 함께 @Transaction 주석 사용 - 봄

글쎄, 난 클래스 @Service 주석 및 일부 이상한 occurrs : 일부 메서드는 내가 Tomcat 서버를 시작할 수 없습니다 @ 주석을 넣어 @ 트랜잭션, 나는 오류가 : "autowired 수 없습니다 ..."다른 클래스에서 때 내 @Autowired를 사용하십시오. 그러나 @Transaction을 제거하면 정상적으로 작동합니다.

내 수업 헤더 :

@Service(value = "caixaBO")
public class CaixaBOImpl extends BasicBOImpl {

그리고 내 메서드 서명은 다음과 같습니다.

@Transactional(propagation = Propagation.REQUIRED)
public void movimentarCaixaPaciente(String descricao, double valor,
        Paciente paciente) {

@Autowired CaixaBOImpl caixaBO를 사용할 때 주석이 @Transaction이므로 초기화 된 tomcat에서 오류가 발생합니다.

편집 1 :

1 - 나는 applicationContext.xml에 transactionManager를 가지고있다.

<!-- Configuracao do gerente de transacoes do Spring -->
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>

2 - pom.xml에 CGLIB가 있습니다.

<dependency>
            <groupId>cglib</groupId>
            <artifactId>cglib-nodep</artifactId>
            <version>2.2.2</version>
        </dependency>

해결법

1. ==============================

   1.내가 생각할 수있는 두 가지 상황이 있습니다.

   내가 생각할 수있는 두 가지 상황이 있습니다.

   어쨌든 CGLIB 프록시가 있더라도 Spring은 JDK 프록시를 사용하고있는 것 같습니다. tx : 특수 효과 기반 선언을로 변경하십시오.

   <tx:annotation-driven proxy-target-class="true" /> 
   

2. ==============================

   2.비슷한 문제가 발생하여 작동하는 것처럼 보이는 "해킹"을 사용했습니다. 클래스가 일부 인터페이스를 구현하게하십시오. 그것은 우리를 위해 일했습니다 - 그것이 당신에게도 효과가 있는지 알려주세요.
