Spring MVC Web.xml配置

Web.xml

spring&spring mvc

在web.xml中定义contextConfigLocation参数，Spring会使用这个参数去加载所有逗号分隔的xml文件，如果没有这个参数，Spring默认加载web-inf/applicationContext.xml文件。

    <!-- spring配置 -->
    <!-- Spring加载的xml文件,不配置默认为applicationContext.xml -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/springConfig.xml</param-value>
    </context-param>

    <!--spring mvc配置-->
    <!-- 配置Sping MVC的DispatcherServlet,也可以配置为继承了DispatcherServlet的自定义类,这里配置spring mvc的配置(扫描controller) -->
    <servlet>
        <servlet-name>springmvcservlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- spring MVC的配置文件 -->
        <init-param>
             <param-name>contextConfigLocation</param-name>
             <param-value>/WEB-INF/springmvc.xml</param-value>
        </init-param>
        <!--其他参数-->
        <init-param>
             <param-name>appName</param-name>
             <param-value>authplatform</param-value>
        </init-param>
        <!-- 下面值小一点比较合适，会优先加载 -->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvcservlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!-- 配置请求过滤器，编码格式设为UTF-8，避免中文乱码 -->
    <filter>
        <filter-name>charsetfilter</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>

        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 该类作为spring的listener使用，它会在创建时自动查找web.xml配置的applicationContext.xml文件 -->
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

    <!-- 此监听器主要用于解决java.beans.Introspector导致的内存泄漏的问题 -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
