springBoot 整合log4j2

因为项目中之前没有引入日志插件，所以我就加了一下。
我是看着这篇博客装的，其中也进行了一些修改。十分感谢

1. 取出springBoot自带的默认日志控件，添加log4j2日志控件
   pom文件中添加一下代码

    <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>1.4.2.RELEASE</version>
    <exclusions><!--   去掉默认配置   -->
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </exclusion>
    </exclusions>
    </dependency>
    <dependency> <!-- 引入log4j2依赖 &ndash;&gt;-->
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-log4j2</artifactId>
        <version>1.4.2.RELEASE</version>
    </dependency>
   

2.在application.properties文件夹下，添加日志配置

logging.config=classpath:log4j2.xml

3.在src/main/resource下新建log4j2.xml，加入对应的配置。（这个参照其他的就OK了） 具体的配置项恐怕得自己去看

4.程序里面直接引入

	private static final Logger logger = LoggerFactory.getLogger(ScheduleJob.class);
	 方法里面用这个就ok了。
	logger.info("this is info ");
