整合log4j

1.导入jar包

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

2.创建log4j.properties

log4j.rootLogger=info,error,CONSOLE,DEBUG
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender     
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout     
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n     
log4j.logger.info=info
log4j.appender.info=org.apache.log4j.DailyRollingFileAppender
log4j.appender.info.layout=org.apache.log4j.PatternLayout     
log4j.appender.info.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  
log4j.appender.info.datePattern='.'yyyy-MM-dd
log4j.appender.info.Threshold = info   
log4j.appender.info.append=true   
#log4j.appender.info.File=/home/admin/pms-api-services/logs/info/api_services_info
log4j.appender.info.File=/Users/dddd/Documents/testspace/pms-api-services/logs/info/api_services_info
log4j.logger.error=error  
log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
log4j.appender.error.layout=org.apache.log4j.PatternLayout     
log4j.appender.error.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  
log4j.appender.error.datePattern='.'yyyy-MM-dd
log4j.appender.error.Threshold = error   
log4j.appender.error.append=true   
#log4j.appender.error.File=/home/admin/pms-api-services/logs/error/api_services_error
log4j.appender.error.File=/Users/dddd/Documents/testspace/pms-api-services/logs/error/api_services_error
log4j.logger.DEBUG=DEBUG
log4j.appender.DEBUG=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DEBUG.layout=org.apache.log4j.PatternLayout     
log4j.appender.DEBUG.layout.ConversionPattern=%d{yyyy-MM-dd-HH-mm} [%t] [%c] [%p] - %m%n  
log4j.appender.DEBUG.datePattern='.'yyyy-MM-dd
log4j.appender.DEBUG.Threshold = DEBUG   
log4j.appender.DEBUG.append=true   
#log4j.appender.DEBUG.File=/home/admin/pms-api-services/logs/debug/api_services_debug
log4j.appender.DEBUG.File=/Users/dddd/Documents/testspace/pms-api-services/logs/debug/api_services_debug

3. 引用

   private static Logger log = Logger.getLogger(UserController.class);

aop方式管理日志

1.导入依赖

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

2.创建配置类

package com.wwg.aop;

import java.util.Enumeration;

import javax.servlet.http.HttpServletRequest;

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;

@Aspect
@Component
public class WebLogAspect {

    private static Logger logger = Logger.getLogger(WebLogAspect.class);

    @Pointcut("execution(public * com.wwg.controller..*.*(..))")
    public void webLog() {
    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 接收到请求，记录请求内容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        logger.info("#####################请求开始####################");
        // 记录下请求内容
        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 {
        // 处理完请求，返回内容
        logger.info("RESPONSE : " + ret);
        logger.info("#####################请求结束####################");
    }
}

3.成功

定时任务

package com.wwg.scheduled;
/*
 * @author wwg
 * @create 2019-07-24 23:11
 * 功能：
 */

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class ScheduledTasks {
        @Scheduled(fixedRate = 1000)
        public void test(){
                //执行任务调度的方法
                System.out.println("-----每秒执行一次-----");
        }

}

记得加上注解
//启动任务调度
@EnableScheduling

异步调用

1.在方法上加

@Async

2.记得加上注解
//开启异步调用
@EnableAsync

读取配置文件

    @Value("配置文件内的名称，如：wwg")
    String wwg;

修改端口号

server.port =8888
server.servlet.contextPath=/wwg

使用yml方式进行配置

好处：简化配置

打包与发布

打包命令：mvn clean package -Dmaven.test.skip=true

发布：在targar目录下打开cmd
输入： java -jar 打包好的jar运行
