Spring Boot Logger方面 [英] Spring Boot Logger Aspects

问题描述

当访问特定包的类中的方法时，我在记录日志信息时遇到问题。换句话说，发生不记录。我甚至绝望并添加了System.out.println语句，没有运气。

I'm having problems getting my logging aspect to log information when methods from classes of a particular package are accessed. In other words, "no" logging occurs. I even got desperate and added System.out.println statements, with no luck.

我的所有课程都位于 org.my.package package，即 org.my.package.controller ， org.my.package.model 等。

All of my classes are located under the org.my.package package, i.e. org.my.package.controller, org.my.package.model, etc.

这是我的Application类：

Here is my Application class:

package org.my.package;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;

@Configuration
@ComponentScan(basePackages = {"org.my.package.config"})
@EnableAutoConfiguration
@EnableAspectJAutoProxy
public class FirstWebAppApplication {

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

这是我的配置类：

package org.my.package.config;

import org.deloitte.javatraining.daythree.utilities.MyLogger;
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
@EnableAspectJAutoProxy
@ComponentScan(basePackages = {"org.my.package.utilities"})
public class AssetConfig {

    //-----------------------------------------------------------------------------------------------------------------------
    @Bean   
    public MyLogger myLogger(){
       return new MyLogger();
    }
}

这是我的Aspect类：

This is my Aspect class:

package org.my.package.utilities;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class MyLogger {

    /** Handle to the log file */
    private final Log log = LogFactory.getLog(getClass());

    public MyLogger () {}

    @AfterReturning("execution(* org.my.package.*.*(..))")
    public void logMethodAccessAfter(JoinPoint joinPoint) {
        log.info("***** Completed: " + joinPoint.getSignature().getName() + " *****");
        System.out.println("***** Completed: " + joinPoint.getSignature().getName() + " *****");
    }

    @Before("execution(* org.my.package.*.*(..))")
    public void logMethodAccessBefore(JoinPoint joinPoint) {
        log.info("***** Starting: " + joinPoint.getSignature().getName() + " *****");
        System.out.println("***** Starting: " + joinPoint.getSignature().getName() + " *****");
    }
}

这些是我的Gradle构建依赖项：

These are my Gradle build dependencies:

dependencies {
    compile("org.springframework.boot:spring-boot-starter-data-jpa")
    compile("org.springframework.boot:spring-boot-starter-web")
    compile('com.h2database:h2:1.3.156')
    compile('javax.servlet:jstl:1.2')
    compile('org.springframework.boot:spring-boot-starter-aop')
    providedRuntime("org.apache.tomcat.embed:tomcat-embed-jasper")
    testCompile("org.springframework.boot:spring-boot-starter-test") 
}

<我错过了什么或者错误配置我的Aspect类吗？在使用其他类似的Stack Overflow问题和在线教程进行验证后，我找不到任何错误。

Am I missing something or otherwise mis-configuring my Aspect class? I can't find anything wrong, after verifying with other, similar Stack Overflow questions and online tutorials.

请提供建议。

推荐答案

你的切入点，执行（* org.my.package。*。*（..）），是仅匹配 org.my.package 包中的类的方法执行而不是子包。

Your point cut, execution( * org.my.package.*.*(..)), is only matching the execution of methods on classes in the org.my.packagepackage not sub packages.

你可能想要的是执行（* org.my.package .. *。*（..））注意 .. 而不是。。

What you probably want is execution( * org.my.package..*.*(..)) notice the .. instead of ..
