Spring Boot2.0之整合log4j

传统方式打印日志比较复杂，每次打印需要定义全局变量

private static final Logger logger = LoggerFactory.getLogger(SjpController.class)

这里我将介绍的是用lombok去简化的方式，只需要加个注解~~~~

1、首先pom文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <modelVersion>4.0.0</modelVersion>

  <groupId>ErrorCatch</groupId>

  <artifactId>com.toov5.ErrorCatch</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <parent>

		<groupId>org.springframework.boot</groupId>

		<artifactId>spring-boot-starter-parent</artifactId>

		<version>2.0.0.RELEASE</version>

	</parent>

	<dependencies>

		<dependency>

			<groupId>org.springframework.boot</groupId>

			<artifactId>spring-boot-starter-web</artifactId>

		</dependency>

		<!-- springboot-log4j -->

		<dependency>

			<groupId>org.springframework.boot</groupId>

			<artifactId>spring-boot-starter-log4j</artifactId>

			<version>1.3.8.RELEASE</version>

		</dependency>

		<dependency>

	<groupId>org.projectlombok</groupId>

	<artifactId>lombok</artifactId>

</dependency>

	</dependencies> 

</project>

2、添加相关依赖到logj.properties文件

#log4j.rootLogger=CONSOLE,info,error,DEBUG

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

log4j\u4EE3\u7801

private static final Logger logger = LoggerFactory.getLogger(IndexController.class);

　后端Java类代码：

　传统型：

package com.toov5.ErrorCatch;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

@RestController //以后经常做微服务异常捕获，要经常用到这个注解

public class ErrorCatch {

    private static final Logger logger = LoggerFactory.getLogger(ErrorCatch.class);

    @RequestMapping("/getUser")

    public String getUser(int i ){

        int j = 1/i;

        logger.info("日志打印记录成功");

        return "返回"+j;

    }

}

访问：

控制台：

lombok+log4j型

很简单~
