Spring Boot AOP加载时间的编织 [英] Spring Boot AOP load time weaving

问题描述

不知道出了什么问题，但是AOP在我的Spring Boot(v1.1.6)安装程序中似乎不起作用.

Not sure what is going wrong, but AOP just doesn't seem to be working in my setup with spring boot (v1.1.6).

@Configuration
@ComponentScan
@EnableJpaRepositories
@EnableTransactionManagement
@EnableAutoConfiguration
@EnableCaching
@EnableLoadTimeWeaving
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

在方面类中

@Aspect
public class MyAspect {
  @AfterReturning(pointcut = "execution(private * com.myapp.service.MyService.test(..)) && args(str1,str2)", argNames = "str1,str2")
    public void advice(String str1, String str2) throws IOException {
        System.out.println("Advising after returning");
    }
}

在需要建议的服务类别中

In the service class that needs the advice

@Service
public class MyService {
  public void test(String str1, String str2) throws IOException {
    System.out.println("Test method in service");
    //rest of the implementation
  }
}

我也有像这样的META-INF/aop.xml

I also have a META-INF/aop.xml like so

<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
    <weaver>
        <!-- only weave classes in our application-specific packages -->
        <include within="com.myapp.*"/>
    </weaver>

    <aspects>
        <!-- weave in just this aspect -->
        <aspect name="com.myapp.aspect.MyAspect"/>
    </aspects>

</aspectj>

当我使用-javaagent:path/to/spring-instrument-4.1.0.RELEASE.jar运行应用程序时

When I run the application with -javaagent:path/to/spring-instrument-4.1.0.RELEASE.jar

我在控制台上收到此消息

I get this message on the console

尽管该建议什么都没有发生.它不会开火.

Nothing happens with the advice though. It won't fire.

我做错什么了吗?

推荐答案

在代码中添加以下更改，它应该可以工作.不需要创建aop.xml.这些更改会将外观添加到容器中并进行编织.

Add below changes to your code and it should work. Do not need to create aop.xml. These changes will add the aspect to container and also weave it.

阅读-启用Spring AOP或AspectJ

@Configuration
@ComponentScan
@EnableJpaRepositories
@EnableTransactionManagement
@EnableAutoConfiguration
@EnableCaching
@EnableAspectJAutoProxy -- Use this instead of @EnableLoadTimeWeaving

public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

@Aspect
 @Component/@Configurable -- Both of them work
 public class MyAspect {
     ...
 }
