Question

当我使用顾问程序api来实现这样的aop日志时，但它不起作用。它的顾问配置类。

@Configuration
public class AspectAutoConfig {

    @Bean
    public DefaultPointcutAdvisor myLogAnnotation() {
        DefaultPointcutAdvisor myLogAdvisor = new DefaultPointcutAdvisor();
        myLogAdvisor.setOrder(Ordered.HIGHEST_PRECEDENCE + 500);
        AnnotationMatchingPointcut myLogAnnotationPointCut =
                new AnnotationMatchingPointcut(MyLog.class, true);
        MethodLogInterceptor logInterceptor = new MethodLogInterceptor();
        myLogAdvisor.setPointcut(myLogAnnotationPointCut);
        myLogAdvisor.setAdvice(logInterceptor);
        return myLogAdvisor;
    }
}

它是拦截器类。

public class MethodLogInterceptor implements MethodInterceptor {

    @Override
    public Object invoke(MethodInvocation invocation) throws Throwable {
        System.out.println("methodName = " + invocation.getMethod().getName()
                + " , arg[] = " + Arrays.toString(invocation.getArguments()));
        try {
            return invocation.proceed();
        } catch (Exception e) {
            throw e;
        } finally {
            System.out.println("finish invoke " + invocation.getMethod().getName());
        }
    }
}

它是应用程序类。

@EnableAspectJAutoProxy(proxyTargetClass = true)
@SpringBootApplication
public class AspectApiApplication {

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

pom。

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>
    </dependencies>

但它不起作用，可以帮助我。谢谢。 github样本是https://github.com/luolibing/coding-life/tree/master/spring-boot-sample/spring-boot-aspect-api

Answer 1

使用带注释的spring aop flavor轻松实现

1：您已启用@EnableAspectJAutoProxy

 @SpringBootApplication
    @EnableAspectJAutoProxy
    class Application {
    //main class
    }

您只需创建自定义方面逻辑

@Aspect
@Component
public class CustomAspect  {

    @Pointcut("@annotation(cn.tim.aspect.api.annotation.MyLog)")
    public void target() {};

@Before("target()")
public void before() {
//do what you want
}
}

你可以@Around，@ Before @After以及更多你的要求这是doc

此处还有一些example of it in github

Answer 2

AnnotationMatchingPointcut myLogAnnotationPointCut = new AnnotationMatchingPointcut(MyLog.class, true);

第一个参数应该是类注解或者为空喜欢

new AnnotationMatchingPointcut(Service.class,MyLog.class, true);

spring boot DefaultPointcutAdvisor不起作用
