spring_mvc中的问题

在看到第三讲的时候碰到java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config错误!
代码如下:
StartController :

复制代码

1. package com.nilpower.test;
   
   import javax.servlet.http.HttpServletRequest;
   import javax.servlet.http.HttpServletResponse;
   
   import org.springframework.web.servlet.ModelAndView;
   import org.springframework.web.servlet.mvc.Controller;
   
   
   
   
   public class StartController implements Controller {
   
   public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
   System.out.println("controller is working!");
   return new ModelAndView("start"); //返回一个逻辑视图
   }
   
   }
   

test-servlet.xml

复制代码

1. <?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"

   <!-- 定义映射处理器 -->
   <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
   <property name="mappings">
   <props>
   <!-- 定义请求的名字为start.test,然后去调用startController处理器 -->
   <prop key="start.test">startController</prop>
   </props>
   </property>
   </bean>
   
   <!-- 控制器 -->
   <bean id="startController" class="com.nilpower.test.StartController"></bean>
   
   <!-- 视图解析器 -->
   <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
   <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>
   <property name="prefix" value="/WEB-INF/jsp/" />
   <property name="suffix" value=".jsp" />
   </bean>
   </beans>

通过http://localhost:8080/SpringMVCTest01/start.test访问时报错.. 具体是因为添加了viewClass.以及org.springframework.web.servlet.view.JstlView

解决办法：

在WEB-INF的lib下面添加：jstl.jar 和 standard.jar就可以了
