      <servlet>
        <servlet-name>springMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <!– 配置SpringMVC前端控制器初始化参数(SprinfMVC配置文件的路径) –>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:springMVC.xml</param-value>
        </init-param>
        <!– 配置SpringMVC前端控制器的优先级 让它在项目启动的时候加载 –>
        <load-on-startup>1</load-on-startup>
      </servlet>

      <servlet-mapping>
        <servlet-name>springMVC</servlet-name>
        <url-pattern>*.action</url-pattern>
      </servlet-mapping>
    </web-app>

5.日志文件配置
  log4j.properties日志文件配置内容如下:

  ### direct log messages to stdout ###
  log4j.appender.stdout=org.apache.log4j.ConsoleAppender
  log4j.appender.stdout.Target=System.err
  log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
  log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L – %m%n

  ### direct messages to file mylog.log ###
  log4j.appender.file=org.apache.log4j.FileAppender
  log4j.appender.file.File=c\:mylog.log
  log4j.appender.file.layout=org.apache.log4j.PatternLayout
  log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L – %m%n

  ### set log levels – for more verbose logging change ‘info’ to ‘debug’ ###

  log4j.rootLogger=info, stdout

注意:最好在项目路径下建立一个config文件夹,将出web.xml以外的其他配置文件放入此文件夹(目的:方便管理)
