豆被初始化爲@Controller但@RequestMapping不會被調用

Question

下面是我對新的Spring 3基於註解的控制器設置：

//調度-servlet.xml中

    </bean> 

<!-- Entity Property binding for webBindingInitializer --> 
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 
     <property name="webBindingInitializer"> 
       <bean class="org.opevel.web.BindingInitializer" /> 
     </property> 
    </bean> 

<context:component-scan base-package="org.opevel.web"/> 

</beans> 

//的web.xml

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

//彈簧控制器

package org.opevel.web; 

@Controller 
public class LoginGoogleController { 

private static final Logger log = Logger.getLogger(LoginGoogleController.class.getName()); 

public LoginGoogleController() { 
    log.info("constructing LoginGoogleController"); 
} 

@RequestMapping(value="/auth", method=RequestMethod.GET) 
public String doGet(HttpServletRequest request, HttpServletResponse response) throws Exception { 

     return "redirect:index"; 

     } 

    } 

當我瀏覽到/ AUTH，我收到了404當我嘗試豆在applicationContext這樣註冊：

<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> 
     <property name="mappings"> 
      <props> 
      <prop key="/auth">GoogleLoginService</prop> 
      </props> 
     </property> 

<bean id="GoogleLoginService" class="org.opevel.web.LoginGoogleController" /> 

我得到一個BeanException，說明該豆通過ControllerClassNamehandlerMapping已經登記在/logingoogle。我在Google App Engine上使用Spring 3.0.2。

會感謝一些幫助。

Answer 1

我能夠解決這個問題，我從應用程序上下文文件中刪除了ControllerClassNameHandlerMapping和SimpleUrlHandlerMapping豆。

關於你們的問候

Answer 2

該錯誤告訴你，你的applicationContext中不需要<bean id="GoogleLoginService" class="org.opevel.web.LoginGoogleController" />。你也不需要<bean id="urlMapping">

@Controller爲你創建一個bean，@RequestMapping創建URL映射。
