我在Eclipse中创建了一个动态项目,但是当我打开时,它抛出了ClassNotFound异常,即#34; Web应用程序[/ HelloWorld]中的Servlet [HelloWorld]抛出了load()异常java.lang.ClassNotFoundException:org .springframework.web.servlet.DispatcherServlet"从服务器。这是一个简单的项目 - HelloWorld。 这是我的web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID" version="3.1">
<display-name>HelloWorld</display-name>
<welcome-file-list>
<welcome-file>redirect.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
</web-app>
这是HelloWorld-servlet.xml:

<property name="prefix" value="/WEB-INF/jsp/">
<property name="suffix" value=".jsp">
</property>
</property>
</property>
</bean>
</context:component-scan>
</beans>
这是redirect.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<% response.sendRedirect("hello.html");%>
这是helloworldcontroller.java
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class helloworldcontroller {
@RequestMapping(value="/hello")
public ModelAndView index(ModelMap m)
{
String mss = "Hello World";
return new ModelAndView("hello", "ms", mss);
}
}
当我导入其他人的某些项目时,它运行时没有异常。但我按照一步一步创建新项目,它总是抛出异常。这让我发疯了。我需要帮忙。谢谢!
