Spring MVC Web.xml配置

本文主要是介绍Spring MVC Web.xml配置，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

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>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>charsetfilter</filter-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>
    </listener>

proxool连接池

    <!-- 数据库连接池 -->
    <servlet>
        <servlet-name>proxoolServletConfigurator</servlet-name>
        <servlet-class>
            org.logicalcobwebs.proxool.configuration.ServletConfigurator
        </servlet-class>
        <init-param>
            <param-name>xmlFile</param-name>
            <param-value>WEB-INF/classes/jdbcproxool.xml</param-value>
        </init-param>
        <load-on-startup>2</load-on-startup>
    </servlet>

webAppRootKey

<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>webapp.root</param-value>
</context-param>

"webapp.root"这个字符串可以随便写任何字符串。如果不配置默认值是"webapp.root"。
可以用System.getProperty("webapp.root")来动态获项目的运行路径。一般返回结果例如：/usr/local/tomcat6/webapps/项目名。

log4j

    <!-- log4j 配置文件路径及监听器 -->
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>
    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.util.Log4jConfigListener
        </listener-class>
    </listener>

资源文件

spring里面有替代标签resource

    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.jpg</url-pattern>
    </servlet-mapping>
