SpringBoot项目使用log4j2

pom.xml添加依赖：

		<!-- springboot默认是用logback的日志框架的，所以需要排除logback，不然会出现jar依赖冲突的报错 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
			<exclusions>
				<exclusion> <!-- exclude掉spring-boot的默认log配置 -->
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-starter-logging</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
		<!-- log4j日志 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-log4j2</artifactId>
		</dependency>
		<!-- 有其他jar依赖log4j -->
		<dependency>
			<groupId>org.apache.logging.log4j</groupId>
			<artifactId>log4j-1.2-api</artifactId>
		</dependency>
		<dependency>
			<groupId>com.lmax</groupId>
			<artifactId>disruptor</artifactId>
			<version>3.3.6</version>
		</dependency>

application.properties添加配置：

#Log4j2
logging.config=classpath:log4j2.xml

src/main/resources添加XML文件：log4j2.xml
