我用的版本     spring5+log4j

网上说spring5把web.xml 里配置的log监听Log4jConfigListener废弃了

spring建议用log4j2 来替换这个类

原来的配置：

web.xml

<context-param>
            <param-name>log4jConfigLocation</param-name>
            <param-value>classpath:config/log4j.properties</param-value>
        </context-param>
    
        
        <context-param>
            <param-name>log4jRefreshInterval</param-name>
            <param-value>10000</param-value>
        </context-param>
    
        
        <listener>
            <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
        </listener>

pom.xml

现在修改为log4j2   pom.xml

<dependency>

    			<artifactId>slf4j-api</artifactId>
    			<version>1.7.21</version>

    			<artifactId>log4j-web</artifactId>
    			<version>2.8.2</version>
    		</dependency>

web.xml

<context-param>
    		<param-name>log4jConfiguration</param-name>
    		<param-value>classpath:config/log4j2.xml</param-value>
    	</context-param>
    	<listener>

    		<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>

设置拦截类

package com.fast.ssm.mybatis.log4j2;
     
    import java.sql.Statement;
    import java.util.Properties;
     
    import org.apache.ibatis.executor.statement.StatementHandler;
    import org.apache.ibatis.plugin.Interceptor;
    import org.apache.ibatis.plugin.Intercepts;
    import org.apache.ibatis.plugin.Invocation;
    import org.apache.ibatis.plugin.Plugin;
    import org.apache.ibatis.plugin.Signature;
    import org.apache.ibatis.session.ResultHandler;
     
    /**
     * Sql执行时间记录拦截器 
     */
    @Intercepts({@Signature(type = StatementHandler.class, method = "query", args = {Statement.class, ResultHandler.class}),
     @Signature(type = StatementHandler.class, method = "update", args = {Statement.class}),
     @Signature(type = StatementHandler.class, method = "batch", args = { Statement.class })})
    public class SqlCostInterceptor implements Interceptor {
     
     @Override
     public Object intercept(Invocation invocation) throws Throwable {
       
      long startTime = System.currentTimeMillis();
      try {
       return invocation.proceed();
      } finally {
       long endTime = System.currentTimeMillis();
       long sqlCost = endTime - startTime;
       System.out.println("执行耗时 : [" + sqlCost + "ms ] ");
      }
     }
     
     @Override
     public Object plugin(Object target) {
      return Plugin.wrap(target, this);
     }
     
     @Override
     public void setProperties(Properties properties) {
       
     }
      
    }

在spring和mybatis的配置文件中加上 拦截器 （我的文件名叫SqlMapConfig.xml）

注意下面的<settings><settings>这个标签的顺序,把它放到<configuration><configuration>里面的最上面，否则启动的时候会报错。

<settings>
            <setting name="logImpl" value="LOG4J2" />
        </settings>
    <plugins>
    		
    		<plugin interceptor="com.fast.ssm.mybatis.log4j2.SqlCostInterceptor"/>
    	</plugins>

如果出现这个报错

修改web.xml头文件  增加红色部分代码

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://java.sun.com/xml/ns/javaee"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    	id="WebApp_ID" version="2.5" metadata-complete="true">

修改pom.xml  log4j jar的版本   如果你选择的最高版本比如  <version>2.11.0</version>  就会出现这个问题

这里建议使用： <version>2.8.2</version> 版本，一般就可以解决这个问题了。
