web 项目的一些常用配置

在动态网站的在web.xml中的一些常用配置

1.过滤字符集：

<filter>
        <description>字符集过滤器</description>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <description>字符集编码</description>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

 2.启动Web容器时，自动装配ApplicationContext的配置信息

<listener>
        <description>spring监听器</description>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

 3. 防止spring内存溢出监听器

<listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>

 4.配置session超时时间，单位分钟

<session-config>
        <session-timeout>15</session-timeout>
    </session-config>
