Spring AOP 有一个名为 CustomizableTraceInterceptor 的方法级跟踪器。 .使用 Spring 的 XML 配置方法，可以像这样设置这个跟踪器:

<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>

我想使用 Spring 的 JavaConfig 样式设置上述配置(即利用 Java 注释，尤其是 @EnableAspectJAutoProxy 用于在 JavaConfig 中激活 AspectJ)。

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = { "some.package" })
@ComponentScan(basePackages = { "some.package2", "some.package3" })
@EnableAspectJAutoProxy
public class FacebookDomainConfiguration {

    @Bean someBean() {
    ...
    }
...
}

什么是@EnableAspectJAutoProxy - 等效于 <aop:advisor advice-ref="customizableTraceInterceptor" ...> 的样式?

最佳答案

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());
    }

}
