25 -SpringBoot學習（6）-整合 log4j

1 整合 log4j

log4j.rootLogger=INFO,Console,File
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c - %L]%m%n
log4j.appender.File = org.apache.log4j.RollingFileAppender
log4j.appender.File.File = D:/info.log
log4j.appender.File.MaxFileSize = 10MB
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c - %L]%m%n

1.1 修改 pom

• 去除springboot的logging，添加log4j，因爲自帶的logging不啓效果
• springboot下的Log4j的版本最新1.3.8，如果你的springboot的parent版本過高，那在在添加log4j自己版本

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>sping-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-log4j</artifactId>
        </dependency>

1.2 測試

2 使用AOP統一處理Web請求日誌

2.1 導入依賴

<!-- AOP -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

2.2 切面類

package com.tzb.springboot.aspect;

import org.apache.log4j.Logger;
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.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.util.Enumeration;

@Aspect
@Component
public class WebLogAspect {
    private Logger logger = Logger.getLogger(getClass());

    @Pointcut("execution(public * com.tzb.springboot.web.controller..*.*(..))")
    public void webLog() {

    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 接收到請求，記錄請求內容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        // 記錄下請求內容
        logger.info("---------------request----------------");
        logger.info("URL : " + request.getRequestURL().toString());
        logger.info("HTTP_METHOD : " + request.getMethod());
        logger.info("IP : " + request.getRemoteAddr());
        Enumeration<String> enu = request.getParameterNames();
        while (enu.hasMoreElements()) {
            String name = (String) enu.nextElement();
            logger.info("name:" + name + "value" + request.getParameter(name));
        }
    }
    @AfterReturning(returning = "ret", pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        logger.info("---------------response----------------");
        // 處理完請求，返回內容
        logger.info("RESPONSE : " + ret);
    }
}
