idea+mybatis+springboot之log4j2配置

log4j2配置，首先在pom文件中排除依赖，并添加log4j2依赖：

<dependency>
   <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-webartifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-loggingartifactId>
        exclusion>
    exclusions>
dependency>

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-log4j2artifactId>
dependency>

在src/main/resource下添加spring-log4j2.xml文件，可免去在application.yml中配置
