JavaSpringAOP：将CustomizableTraceInterceptor与JavaConfig@enableSpectJautoproxy一起使用，而不是使用XML<；aop:advisor>；

SpringAOP有一个方法级跟踪程序，名为

CustomizelTraceInterceptor

。使用Spring的XML配置方法，可以这样设置跟踪程序：

<bean id="customizableTraceInterceptor" class="
  org.springframework.aop.interceptor.CustomizableTraceInterceptor">
  <property name="enterMessage" value="Entering $[methodName]($[arguments])"/>
  <property name="exitMessage" value="Leaving $[methodName](): $[returnValue]"/>
</bean>

<aop:config>
  <aop:advisor advice-ref="customizableTraceInterceptor"
    pointcut="execution(public * org.springframework.data.jpa.repository.JpaRepository+.*(..))"/>
</aop:config>

的

@EnableAspectJAutoProxy

-样式等价物是什么？

不幸的是，您不能这样做，因为Java语言不支持Spring JavaConfig中支持此功能所需的方法文本。为此打开了一个bug，但标记为“无法修复”：

错误报告中提到的两个选项是：

继续使用

，方法是使用

@ImportResource

将任何现有的

元素转换为使用

@Aspect

样式。[这在

CustomizableTraceInterceptor中是不可能的]

我是这样做的：

@Configuration
@EnableAspectJAutoProxy(proxyTargetClass=true)
public class TraceLoggerConfig {

    @Bean
    public CustomizableTraceInterceptor customizableTraceInterceptor() {
        CustomizableTraceInterceptor customizableTraceInterceptor = new CustomizableTraceInterceptor();
        customizableTraceInterceptor.setUseDynamicLogger(true);
        customizableTraceInterceptor.setEnterMessage("Entering $[methodName]($[arguments])");
        customizableTraceInterceptor.setExitMessage("Leaving  $[methodName](), returned $[returnValue]");
        return customizableTraceInterceptor;
    }

    @Bean
    public Advisor jpaRepositoryAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression("execution(public * org.springframework.data.jpa.repository.JpaRepository+.*(..))");
        return new DefaultPointcutAdvisor(pointcut, customizableTraceInterceptor());
    }

}

只是想增加Adrence的反应。 我将使用点表达式引用聚合点，更清晰的分隔，imho

package org.example;

@Configuration
@EnableAspectJAutoProxy
@Aspect
public class AopConfiguration {
    /** Pointcut for execution of methods on {@link Service} annotation */
    @Pointcut("execution(public * (@org.springframework.stereotype.Service org.example..*).*(..))")
    public void serviceAnnotation() { }

    /** Pointcut for execution of methods on {@link Repository} annotation */
    @Pointcut("execution(public * (@org.springframework.stereotype.Repository org.example..*).*(..))")
    public void repositoryAnnotation() {}

    /** Pointcut for execution of methods on {@link JpaRepository} interfaces */
    @Pointcut("execution(public * org.springframework.data.jpa.repository.JpaRepository+.*(..))")
    public void jpaRepository() {}

    @Pointcut("serviceAnnotation() || repositoryAnnotation() || jpaRepository()")
    public void performanceMonitor() {}

    @Bean
    public PerformanceMonitorInterceptor performanceMonitorInterceptor() {
        return new PerformanceMonitorInterceptor(true);
    }

    @Bean
    public Advisor performanceMonitorAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression("org.example.AopConfiguration.performanceMonitor()");
        return new DefaultPointcutAdvisor(pointcut, performanceMonitorInterceptor());
    }
}

谢谢这应该被认为是正确答案。我使用上面的代码，但是

customabletraceinterceptor

似乎没有触发。我的拙见是，这应该被标记为正确答案，只是用Spring 4验证了一下。：）谢谢你们！我从早上开始就一直在寻找这个解决方案！））

package org.example;

@Configuration
@EnableAspectJAutoProxy
@Aspect
public class AopConfiguration {
    /** Pointcut for execution of methods on {@link Service} annotation */
    @Pointcut("execution(public * (@org.springframework.stereotype.Service org.example..*).*(..))")
    public void serviceAnnotation() { }

    /** Pointcut for execution of methods on {@link Repository} annotation */
    @Pointcut("execution(public * (@org.springframework.stereotype.Repository org.example..*).*(..))")
    public void repositoryAnnotation() {}

    /** Pointcut for execution of methods on {@link JpaRepository} interfaces */
    @Pointcut("execution(public * org.springframework.data.jpa.repository.JpaRepository+.*(..))")
    public void jpaRepository() {}

    @Pointcut("serviceAnnotation() || repositoryAnnotation() || jpaRepository()")
    public void performanceMonitor() {}

    @Bean
    public PerformanceMonitorInterceptor performanceMonitorInterceptor() {
        return new PerformanceMonitorInterceptor(true);
    }

    @Bean
    public Advisor performanceMonitorAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression("org.example.AopConfiguration.performanceMonitor()");
        return new DefaultPointcutAdvisor(pointcut, performanceMonitorInterceptor());
    }
}
