Spring : ClassNotFound异常
Spring : ClassNotFound异常
提问于 2016-06-28 06:57:47
我正在用spring启动一个新项目，当我试图运行hello时，它正在抛出错误：
这是我的dispatcher-servlet.xml映射：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<bean name="/welcome.html"
class="com.shaurya.FirstController" />
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix">
<value>/WEB-INF/jsp/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
</beans>这是web.xml：
<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>Spring Web MVC Application</display-name>
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
</web-app>控制器代码在这里：
package com.shaurya;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController
public class FirstController extends AbstractController{
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
String message="welcome to Spring";
ModelAndView model= new ModelAndView("welcome");
model.addObject("message", message);
return model;
}
}这是控制器呈现welcome.jsp的视图页：
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<a href="welcome.html">sdsd</a>
</body>
</html>为什么会出现错误，似乎如下所示：
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.shaurya.FirstController] for bean with name'/welcome.html' enter code heredefined in ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml]; nested exception is java.lang.ClassNotFoundException: com.shaurya.FirstController.有什么建议吗？

你能试着改变这段代码吗？
<bean name="/welcome.html"
class="com.shaurya.FirstController" />到这个
<bean name="/welcome"
class="com.shaurya.FirstController" />由于.html的映射已经在web.xml中完成了，所以您可能不需要在bean映射中再次提及它
