ssh整合log4j（控制台，本地文件，数据库）

1.web.xml中添加：

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>WEB-INF/classes/log4j.properties</param-value>
</context-param>
<context-param>
    <param-name>log4jRefreshInterval</param-name>
    <param-value>6000</param-value>
</context-param>
<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>webApp.root</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
