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>
<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>
