Spring Boot Logger 方面 [英] Spring Boot Logger Aspects
问题描述
当访问来自特定包的类的方法时,我在获取日志方面以记录信息时遇到问题.换句话说,发生无"日志记录.我什至绝望并添加了 System.out.println 语句,但没有运气.
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.
我的所有类都位于org.my.package 包下,即org.my.package.controller、org.my.package.模型等
All of my classes are located under the org.my.package package, i.e. org.my.package.controller, org.my.package.model, etc.
这是我的应用程序类:
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")
}
我是否遗漏了什么或以其他方式错误地配置了我的 Aspect 类?在与其他类似的 Stack Overflow 问题和在线教程验证后,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.
请指教.
推荐答案
你的切入点,execution( * org.my.package.*.*(..))
,只匹配在 org.my.package
包而不是子包中的类上执行方法.
Your point cut, execution( * org.my.package.*.*(..))
, is only matching the execution of methods on classes in the org.my.package
package not sub packages.
您可能想要的是 execution( * org.my.package..*.*(..))
注意 ..
而不是 .代码>.
What you probably want is execution( * org.my.package..*.*(..))
notice the ..
instead of .
.
