aop：aspectj-autoproxy和tx：春天的注释驱动冲突

问题描述 投票：0回答：3

这是我使用spring AOP的第一个项目。添加时出现问题

<aop:aspectj-autoproxy proxy-target-class="true" />

在我的spring-servlet.xml中。如果我从上下文文件应用程序注释这一行运行正常，没有错误。

如果我添加此行，则抛出异常。

这是我的方面课。

@Aspect
@Component
public class MyItemDaoLoggingAspect {

    //this is wher we add all aspect logic 

    //@Before advice

    @Before("execution(public List getAllItems())")
    public void beforeVaalidateMyItem() {
        System.out.println(" ========> In MyItemDaoLoggingAspect");
        System.out.println(" ========> Executing beforeAscpect for validateMyItem");
    }
}

这是我的道法。

public List getAllItems() {
    Session session = sessionFactory.getCurrentSession();
    return session.createCriteria(MyItem.class).list();
}

这是我的应用程序配置文件。

这对我有帮助。我将返回类型List更改为java.util.List。

How to intercept the return type List using the spring AOP pointcut expression

@Aspect
@Component
public class MyItemDaoLoggingAspect {

    //this is wher we add all aspect logic 

    //@Before advice

    @Before("execution(public java.util.List getAllItems())")
    public void beforeVaalidateMyItem() {
        System.out.println(" ========> In MyItemDaoLoggingAspect");
        System.out.println(" ========> Executing beforeAscpect for validateMyItem");
    }
}

这一行导致问题：@Before（“execution（public List getAllItems（））”）

您需要删除访问修饰符并返回执行中使用的方法的类型，并在该方法存在时添加完全限定的类名。见下文

@Before（“执行（把完全限定的类名称放在here.getAllItems（））”）

有两件事可能会导致代码出现问题。

1.您尚未定义完全限定的方法名称。需要最少的通配符。

2.你已经在你的切入点中指定了访问修饰符作为公共和代理机制你使用proxy-target-class="true"强制spring使用CGLIB代理机制。但是根据“https://tenmilesquare.com/using-gclib-with-proxy-target-class-true/”CGLIB不会代理任何公共方法。

因此我建议将切入点更改为以下内容。

"execution(* packageName.*.getAllItems(..))"

或者使用proxy-target-class="false"在切入点中尝试使用完全限定的方法名称

有关切入点签名的更多详细信息，请参阅https://docs.spring.io/spring/docs/3.0.0.M4/reference/html/ch07s02.html上的第7.2.3.4节
