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.
@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 {
...
}
