最近,我将我的静态html文件之一切换到了使用JSP呈现其视图的Spring控制器。我使用码头进行本地测试,本地测试显示页面渲染良好。部署到使用Tomcat 6.0.26的测试服务器后,出现以下异常:
javax.servlet.ServletException: Could not get RequestDispatcher for [/WEB-INF/jsp/index.jsp]: check that this file exists within your WAR org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:219) org.springframework.web.servlet.view.AbstractView.render(AbstractView.java:250) org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1060) org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:798) org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:716) org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:644) org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:549) javax.servlet.http.HttpServlet.service(HttpServlet.java:617) javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
我已经确认JSP存在于我部署的战争以及tomcat部署时创建的分解目录中。以下是我的web.xml和front-controller- servlet.xml文件的外观(web.xml略有缩短):
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- Initialize the Spring DispatcherServlet --> <servlet> <servlet-name>gwtrpc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- Map the DispatcherServlet to only intercept RPC requests --> <servlet-mapping> <servlet-name>gwtrpc</servlet-name> <url-pattern>*.gwtrpc</url-pattern> </servlet-mapping> <servlet> <servlet-name>front-controller</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>front-controller</servlet-name> <url-pattern>/search.html</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>front-controller</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
front-controller-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:security="http://www.springframework.org/schema/security" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/search.html">indexController</prop> </props> </property> </bean> <bean id="indexController" class="com.company.search.web.server.controller.IndexController" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp"/> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> </bean> </beans>
开发实例和测试实例之间的区别在于,开发实例部署到了根目录(localhost / search.html),而测试实例则部署到了server.com/appname/search.html。Appname是我部署的* .war文件的名称。我尝试将完整路径作为前缀添加到jps文件(/ appname / WEB-INF / jsp /)和许多其他没有运气的组合中。我已经验证了jsp-api jar位于tomcat lib目录中。我的tomcat安装是基本/默认安装。
该问题是由于从tomcat安装的默认web.xml中删除了默认的jsp servlet引起的。这是由一位前同事完成的,而据我所知。将测试服务器的web.xml替换为默认的web.xml(包括用于处理jsp文件的url- patterns / servlet)可以解决此问题。
