SpringBoot-业务中优雅的打印日志

概述

如何在业务中打印日志，通常做法是使用log.info(...)输出日志。 今天使用aop拦截器打印日志

实现

package com.open4play.center.infrastructure.aop;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.aop.Advisor;
import org.springframework.aop.aspectj.AspectJExpressionPointcut;
import org.springframework.aop.interceptor.CustomizableTraceInterceptor;
import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;

@EnableAspectJAutoProxy(proxyTargetClass = true)
@Aspect
@Configuration
public class TraceAopConfig {

  @Pointcut("execution(* com.open4play.center.controller..*.*(..))")
  public void monitor() {}

  /**
   * 监控追踪
   * @return Advisor
   */
  @Bean
  public Advisor traceAdvisor() {
    CustomizableTraceInterceptor customizableTraceInterceptor = new CustomizableTraceInterceptor();
    customizableTraceInterceptor.setEnterMessage("Enter ClassName=$[targetClassName]: $[methodName]($[arguments])");
    customizableTraceInterceptor.setExitMessage("Exit $[methodName]: $[returnValue]");
    customizableTraceInterceptor.setUseDynamicLogger(true);
    AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
    pointcut.setExpression("com.open4play.center.infrastructure.aop.TraceAopConfig.monitor()");
    return new DefaultPointcutAdvisor(pointcut, customizableTraceInterceptor);
  }

}
