## 环境搭建 ##

*  [log4j2链接][log4j2]

在pom.xml文件中引入log4j2依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency> 
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>

## log4j2.xml配置 ##

将log4j2.xml文件放在项目的resources下，配置中都有基本注释，对于特殊需求，只需简单更改一下配置即可。  
注意：

*  对于需要过滤掉的配置，修改Logger，设置为info
