Spring自动装配失败，因为proxy-target et-class="true"和

提问者：小点点

Spring自动装配失败，因为proxy-target et-class="true"和<aop： aspectj-autoproxy/>

我有以下Spring配置：

<context:annotation-config />
<security:global-method-security jsr250-annotations="enabled"  pre-post-annotations="enabled" proxy-target-class="true" />

<tx:annotation-driven  />

<aop:aspectj-autoproxy />

<context:component-scan base-package="com.web,com.security" />

我在global-method-security中启用了proxy-target-class，因为我想在控制器中使用@PreAuthorize注释（我知道Spring team不鼓励这样做），并在保存对象时使用aop aspectJ作为服务中的“拦截器”。

似乎是因为全局方法安全中的代理配置已启用并且默认的aop aspectj正在使用代理实现。它未能在所有控制器中自动装配bean。代理代理？

控制器

@RequestMapping(value = "add")
@PreAuthorize("@securityPermission.validatePermission()")
public String add(Model model) {
   //codes
}

我的带有@Aspect注释的服务类

@SuppressWarnings("serial")
@Aspect
@Service
public class InterceptorServiceImpl extends BaseServiceImplementation implements InterceptorService {
@Autowired
    private LogRepository logRepository;

@Around("execution(* com.repository.CardRequestRepository.save(..))")
@Transactional(readOnly = false, propagation = Propagation.REQUIRED, rollbackFor = Exception.class,timeout = 30)
   public Object checkProcess(ProceedingJoinPoint joinPoint) throws Throwable{
   LOGGER.info("SERVICE : START Process checking Interceptor");

}

是否可以同时使用aop： aspectj-autoproxy并启用proxy-target et-class？或者有人有其他建议吗？：）

自动配线失败问题已解决

根据@M. Deina的建议，我解决了我的自动装配问题，在以下位置添加了proxy-target et-class="true"属性：

<tx:annotation-driven /> 
<cache:annotation-driven />
<aop:aspectj-autoproxy />

我用@Aspect注释删除了类中的@Service。

注意：在InterceptorServiceImpl中，我使用@Service是因为我希望@Autowing调用存储库/服务bean

发生的方面类问题：

似乎是因为我在我的方面类中删除了@Service注释，aop aspectj不知何故没有执行，并且我的日志中没有错误。

我解决了我的问题，似乎是因为在我的存储库类中使用了数据jpa（JpaRepository）。这是我的xml配置：

<security:global-method-security jsr250-annotations="enabled" pre-post-annotations="enabled" proxy-target-class="true"/> //enabled proxy to use @preAuthorize in controller
<tx:annotation-driven />
<cache:annotation-driven />
<aop:aspectj-autoproxy />
<context:component-scan base-package="com.xxx.xxx.service.serviceimplementasi" />  
<jpa:repositories  base-package="com.csl.cms.repository" entity-manager-factory-ref="entityManagerFactory" transaction-manager-ref="transactionManager"  />

数据jpa配置：

<!--Spring Data JPA Configuration-->
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" >
        <property name="dataSource" ref="c3p0DataSource-1" />
        <property name="packagesToScan" value="com.xxx.xxx.entity"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="databasePlatform" value="${database.dialect}" /> 
                <property name="showSql" value="true" />
                <property name="generateDdl" value="true" />
            </bean>
        </property>
    </bean>
    <bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />        
        <property name="jpaDialect">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
        </property>
    </bean>

存储库类：

public interface CardRequestRepository extends JpaRepository<CardRequest, Long>, CardRequestRepositoryCustom {
    public List<CardRequest> findByCardholderId(Long cardholderId);

在CardRequest estRepositoryCustom类中，使用entityManager创建自定义保存方法，因此它不会依赖于JpaRepository类。

public class CardRequestRepositoryImpl implements CardRequestRepositoryCustom {

    @PersistenceContext
    private EntityManager em;

 @Override
    public CardRequest customSave(CardRequest cardRequest) {
       em.persist(cardRequest);
       return cardRequest;
    }

我还在我的方面类中更改了我的切点类，使用存储库自定义类：

@SuppressWarnings("serial")
@Aspect
@Component
public class ApprovalInterceptorServiceImpl extends BaseServiceImplementasi implements ApprovalInterceptorService {

    @Autowired
    private LifecycleLogRepository lifecycleLogRepository;
    @Autowired
    private ApprovalDefinitionRepository approvalDefinitionRepository;
    @Around("execution(* com.xxx.xxx.repository.repositoryimplementasi.CardRequestRepositoryImpl.customSave(..))")
    @Transactional(readOnly = false, propagation = Propagation.REQUIRED, rollbackFor = Exception.class,timeout = 30)
    public CardRequest checkApprovalProcess(ProceedingJoinPoint joinPoint) throws Throwable{
    LOGGER.info("SERVICE : START Approval Process checking Interceptor");
                System.out.println("SERVICE : START Approval Process checking Interceptor");

                Object messageParam[] = new Object[1];
        Object[] objs = joinPoint.getArgs();
        CardRequest cardRequest = (CardRequest) objs[0];

....

在aop方面类中，使用@Component来自动安装服务bean，并且不使用jpaRepository扩展存储库类，而是使用/create自定义存储库类和entityManager来保存对象。

如果我在我的方面类中应用了@Component、@Autowed并使用jpaRepository，则存储库bean类无法自动编辑。仍然不知道为什么会发生这种情况。
