Myeclipse2014提示：ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j

报错关键信息如下：

ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
log4j:ERROR Could not find value for key log4j.appender.D
log4j:ERROR Could not instantiate appender named "D".

1.在启动Tomcat服务器时报错，在网上查找资料发现原来是少了一个配置文件导致，需要新建一个log4j2.xml文件。

2.可以在F:\MJWWorkspaces\SpringMVC_Spring_mybatis\WebRoot\WEB-INF\classes下添加一个log4j2.xml文件（路径参考自己项目的workspaces路径,具体操作可参考myeclipse→windows→preferences→general→startup and shutdown→workspaces→就可以找到项目路径）;

添加log4j2.xml也可以在myeclipse上进行，右键项目名称→buildpath→configure build path→add folder，然后在XXX/webroot/web-inf/class 下添加log4j2.xml.

也可以在workspace路径下直接添加如下图操作：

log4j2.xml内容如下：

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

<Configuration status="warn">  
            <Appenders>  
                        <Console name="Console" target="SYSTEM_OUT">  
                                    <PatternLayout pattern="[%-5p] %d %c - %m%n" />  
                        </Console>  
                        <File name="File" fileName="dist/my.log">  
                                    <PatternLayout pattern="%m%n" />  
                        </File>  
            </Appenders>  
  
            <Loggers>  
                        <Logger name="mh.sample2.Log4jTest2" level="INFO">  
                                    <AppenderRef ref="File" />  
                        </Logger>  
                        <Root level="INFO">  
                                    <AppenderRef ref="Console" />  
                        </Root>  
            </Loggers>  
</Configuration>  

3.然后重新启动服务。
