Spring：創建名爲'controller.HelloController＃0'的bean時出錯設置屬性值時出錯

試圖弄清楚這一點，我確定我的setter和getters是可以的。這是一個從here Spring：創建名爲'controller.HelloController＃0'的bean時出錯設置屬性值時出錯

一個嘖嘖這是我的錯誤

這是我dispathcer-的servlet

<?xml version="1.0" encoding="UTF-8"?>

<bean class="controller.HelloController" p:helloService-ref="helloService"/> 
    <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/> 

    <!-- 
    Most controllers will use the ControllerClassNameHandlerMapping above, but 
    for the index controller we are using ParameterizableViewController, so we must 
    define an explicit mapping for it. 
    --> 
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> 
     <property name="mappings"> 
      <props> 
       <prop key="index.htm">indexController</prop> 
      </props> 
     </property> 
    </bean> 

    <bean id="viewResolver" 
      class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
      p:prefix="/WEB-INF/jsp/" 
      p:suffix=".jsp" /> 

    <!-- 
    The index controller. 
    --> 
    <bean name="indexController" 
      class="org.springframework.web.servlet.mvc.ParameterizableViewController" 
      p:viewName="index" /> 




</beans>

這是HelloController中

/* 
* To change this template, choose Tools | Templates 
* and open the template in the editor. 
*/ 
package controller; 

import java.net.BindException; 
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; 

/** 
* 
* @author ahmed 
*/ 
public class HelloController extends SimpleFormController { 

    public HelloController() { 
     //Initialize controller properties here or 
     //in the Web Application Context 

     setCommandClass(Name.class); 
     setCommandName("Name"); 
     setSuccessView("helloView"); 
     setFormView("nameView"); 
    } 

    //Use onSubmit instead of doSubmitAction 
    //when you need access to the Request, Response, or BindException objects 

    //@Override 
protected ModelAndView onSubmit(
      HttpServletRequest request, 
      HttpServletResponse response, 
      Object command, 
      BindException errors) throws Exception { 

     Name name = (Name) command; 
     ModelAndView mv = new ModelAndView(getSuccessView()); 
     mv.addObject("helloMessage", HelloService.sayHello(name.getValue())); 
     return mv; 
    } 

}

最後Name.java

/* 
* To change this template, choose Tools | Templates 
* and open the template in the editor. 
*/ 
package controller; 

/** 
* 
* @author ahmed 
*/ 
public class Name { 
    private String value; 

    public String getValue() { 
     return value; 
    } 

    public void setValue(String value) { 
     this.value = value; 
    } 


}

請讓我知道如果我需要顯示任何其他代碼的部分，我看了幾天，現在找不到解決方案。

感謝

根據dispatcher-servlet.xml錯誤，你不應該在你的HelloController類setHelloService方法？

哦，是的，我認爲這是，我對你有鏈接的教程只是檢查的問題，請看一看點15

我想這是更復雜的比，所以我不會覺得自己像一個工具....哦，太晚了。感謝百萬人花時間弄清楚。 – 2013-03-19 18:09:37
