spring mvc 项目 相关配置文件小结

web.xml文件主要配置如下:

需要加载的配置文件: 类路径下,可以使用通配符配置  类似:classpath:conf/spring/*/*.xml,

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
             classpath:conf/spring/spring-da.xml,
             classpath:conf/spring/spring-res.xml,
        </param-value>
    </context-param>

上下文加载过滤:

<!-- 上下文加载器 加载 context-param -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

excel模板下载,防止出现压缩包的情况.

<!-- excel模板下载 -->
    <mime-mapping>
        <extension>xlsx</extension>
        <mime-type>application/vnd.openxmlformats</mime-type>
    </mime-mapping>

字符过滤器:防止前后台的中文乱码,当然,最好还是保证 前台页面utf-8 后台的编码也是utf-8

<!-- 字符过滤器 -->
    <filter>
        <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
        <url-pattern>*</url-pattern>
    </filter-mapping>

SPring mvc的总控制分发配置:

<!-- Spring MVC 总控制器 DispatcherServlet -->
    <servlet>
        <servlet-name>pmp</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:conf/spring/spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>pmp</servlet-name>
        <url-pattern>*.htm</url-pattern>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>

容器校验登录控制,以及请求的拦截:

<!-- security start -->
    <security-constraint>
        <web-resource-collection>
            <web-resource-name>pmp-web-in</web-resource-name>
            <url-pattern>/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
            <role-name>*</role-name>
        </auth-constraint>
    </security-constraint>
    <security-constraint>
        <web-resource-collection>
            <web-resource-name>pmp-web-in</web-resource-name>
            <url-pattern>/RES/*</url-pattern>
            <url-pattern>/login.jsp</url-pattern>
            <url-pattern>/home/error.htm</url-pattern>       
        </web-resource-collection>
    </security-constraint>
    <login-config>
        <auth-method>FORM</auth-method>
        <form-login-config>
            <form-login-page>/login.jsp</form-login-page>
            <form-error-page>/login.jsp</form-error-page>
        </form-login-config>
    </login-config>
    <security-role>
        <description>framework user role</description>
        <role-name>*</role-name>
    </security-role>
    <!-- security end -->

欢迎页面以及错误跳转配置:

<welcome-file-list>
        <welcome-file>redirect.jsp</welcome-file>
    </welcome-file-list>
    <error-page>
        <exception-type>java.lang.Throwable</exception-type>
        <location>/home/error.htm?errorCode=500</location>
    </error-page>
    <error-page>
        <error-code>500</error-code>
        <location>/home/error.htm?errorCode=500</location>
    </error-page>
    <error-page>
        <error-code>404</error-code>
        <location>/home/error.htm?errorCode=404</location>
    </error-page>
    <error-page>
        <error-code>403</error-code>
        <location>/home/error.htm?errorCode=403</location>
    </error-page>

以上是项目中web.xml的基本的配置信息,可以根据自身的项目信息增加和删除相关的配置项.
