你好我是MVC Spring的新手。我使用Spring创建了简单的应用程序。我使用etbeans 7.3.1 Ide,我使用Spring版本2.5.6。当我尝试运行我的应用程序时,它给我一个错误,如调度程序抛出异常。我为我的应用程序创建了以下类。  HelloController.java和Name1.java,如下所示。

package controller;
import java.net.BindException;
import java.util.jar.Attributes.Name;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import service.HelloService;
import controller.Name1;

public class HelloController extends SimpleFormController {
private HelloService helloService;
public HelloController()
 {
    setCommandClass(Name.class);
    setCommandName("name");
    setSuccessView("helloView");
    setFormView("nameView");
    }
    protected ModelAndView onSubmit(HttpServletRequest  
            request,HttpServletResponse response,Object 
            command,BindException errors) throws Exception {
    Name1 name = (Name1) command;
    ModelAndView mv = new ModelAndView(getSuccessView());
    mv.addObject("helloMessage", helloService.sayHello(name.getValue()));
    return mv;
        }
}

现在我正在展示Name1.java

    package controller;

public class Name1
{
 private String value;
     public String getValue()
     {
        return value;
     }
      public void setValue(String value)
     { 
      this.value = value;
 }
   }

HelloService.java

 package service;

 import controller.Name1;
 public class HelloService 
 {
    public static String sayHello(String name)
    {
     return "Hello " + name + "!";
     }
  }

现在我是Show dispatcher-servlet.xml文件。

   <?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:p="http://www.springframework.org/schema/p"

   /aop/spring-aop-2.5.xsd
   http://www.springframework.org/schema/tx http://www.springframework.org/schema
   /tx/spring-tx-2.5.xsd">
   <bean  
 class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>
   <bean class="controller.HelloController" p:helloService-ref="helloService"/>
   <bean id="urlMapping" 
  class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <props>
            <prop key="hello.htm">indexController</prop>
        </props>
    </property>
  </bean>
  <bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/jsp/"
      p:suffix=".jsp" />

<bean name="indexController"
      class="org.springframework.web.servlet.mvc.ParameterizableViewController"
      p:viewName="hello" />
  </beans>

现在我向您展示我的2个jsp文件,该文件在下面给出

Helloview.jsp

    <%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Hello</title>
</head>
<body>
    <h1>${helloMessage}</h1>
</body>

</html>

nameView.JSP中

     <%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib uri="http://www.springframework.org/tags" prefix="spring" %>
<!DOCTYPE html>
<html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Name View</title>
    </head>
    <body>
    <spring:nestedPath path="name">
    <form action="" method="post">
    Name:
    <spring:bind path="value">
        <input type="text" name="${status.expression}" value="${status.value}">
    </spring:bind>
    <input type="submit" value="OK">
    </form>
</spring:nestedPath>

    </body>
</html>

我的踪迹在下面给出。     类型异常报告

我也改变了项目的属性。从右键单击项目然后属性 - >运行 - &gt; RelaticURL = hello.htm然后我运行我的项目我得到了我在标题中提到的错误。所以请帮助我......我犯了错误。 谢谢。
