嗨,我有一个没有触发的Aspect的问题,我不知道为什么。以下是我的项目:

注释:

import java.lang.annotation.*;


@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
public @interface Profiled {
}

方面:

import org.apache.log4j.Logger;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;



@Aspect
public class ProfiledAspect {
final static Logger logger = Logger.getLogger(ProfiledAspect.class);
private final String TIME_UNIT = "ms";

@Around("@annotation(annotation)")
public Object profile(ProceedingJoinPoint pjp, Profiled annotation) throws Throwable {
    long start = System.nanoTime();
    Object result = pjp.proceed();
    long end= System.nanoTime();

    long duration = end - start;

    System.out.println("Duration: " + duration + "nano secs.");
    return result;
}
}

这是我的配置类:

import com.myexample.aop.ProfiledAspect;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;


@Configuration
@ComponentScan(basePackages = {"com.myexample"})
@EnableAspectJAutoProxy
public class AppConfig {

@Bean
public ProfiledAspect profiledAspect(){
    return new ProfiledAspect();
}

}

这是我的班级,我使用注释触发方面:

import com.myexample.aop.Profiled;
import org.springframework.stereotype.Service;

@Service
public class TestAnnotationClass {

@Profiled
public void testAnnotationClass()  {
 System.out.println("test profile annotation");
}


}

以下是我用于AOP事物的maven依赖

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>4.3.7.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.8.10</version>
        </dependency>

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.8.10</version>
        </dependency>

知道为什么没有触发方面?

2 个答案:

@Around

中是否缺少Profiled Annotation
@Around("@annotation(com.example.Profiled)")
public Object profile(ProceedingJoinPoint pjp, Profiled annotation) throws Throwable {
    ...
}

您可以将方面设为@Component并通过组件扫描获取它,而不是手动实例化。

另一个想法是使用@EnableAspectJAutoProxy(proxyTargetClass=true)因为你的目标类没有实现可以由JDK代理代理的接口,而是一个简单的类。为此,您需要一个CGLIB代理。
