springmvc 加入log4j2日志

这次记录下springmvc加入log4j2的日志。

1.在pom文件中加入log4j2相关的依赖

<!-- log4j2   -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.1</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.1</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-web</artifactId>
<version>2.1</version>
</dependency>

2.在web.xml文件中添加Log4j2的相关配置信息

<!--    log4j2   -->
<context-param>
<param-name>isLog4jAutoInitializationDisabled</param-name>
<param-value>false</param-value>
</context-param>
<!-- 默认就会找这个文件，不需要额外配置引用
<context-param>
<param-name>log4jConfiguration</param-name>
<param-value>classpath:/log4j2.xml</param-value>
</context-param>
-->
<listener>
<listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
</listener>

<filter>
<filter-name>log4jServletFilter</filter-name>
<filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>log4jServletFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>

3.在resources下加入log4j2.xml.给出我的仅供参考

<?xml version="1.0" encoding="UTF-8"?>

<!--
status : 这个用于设置log4j2自身内部的信息输出,可以不设置,当设置成trace时,会看到log4j2内部各种详细输出
monitorInterval : Log4j能够自动检测修改配置文件和重新配置本身, 设置间隔秒数。
-->
<Configuration status="WARN" monitorInterval="30">
<!--
日志级别
共有8个级别，按照从低到高为：All < Trace < Debug < Info < Warn < Error < Fatal < OFF.
-->
<!-- 配置日志文件输出目录 -->

append 决定是否在原日志末尾追加日志。调试的时候可以设置为false,很方便

4.用LogManager.getLogger(）获取到log对象，然后打印日志就ok了

@Controller
@RequestMapping("test")
public class TestController {
private  static final  Logger logger = LogManager.getLogger(TestController.class);
@RequestMapping("index")
@ResponseBody
public String test(){
logger.info("a info data");
logger.debug("a debug data");
logger.error("a error data");
return "index";
}
}
