我的Spring MVC配置有什麼問題？

Question

我試圖設置和學習如何使用Spring MVC開發Web應用程序。我一直在試圖遵循一些教程，但我的應用程序似乎並不想工作。

ENVIRO：Eclipse中，M2E-WTP，彈簧，整個事情

上下文根是BidApp。

我有一個控制器：

@Controller 
public class AuctionController {  
    @RequestMapping("/hello") 
    public ModelAndView helloWorld() { 
     String message = "Hello World, Spring 3.0!"; 
     return new ModelAndView("hello", "message", message); 
    } 
} 

我在WEB-INF的web.xml：

<!DOCTYPE web-app PUBLIC 
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 
"http://java.sun.com/dtd/web-app_2_3.dtd" > 

<web-app> 
    <display-name>BidApp</display-name> 
    <servlet> 
     <servlet-name>dispatcher</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet 
     </servlet-class> 
     <load-on-startup>1</load-on-startup> 
     <init-param> 
      <param-name>contextConfigLocation</param-name> 
      <param-value>/WEB-INF/spring-servlet.xml</param-value> 
     </init-param> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>dispatcher</servlet-name> 
     <url-pattern>*.*</url-pattern> 
    </servlet-mapping> 
</web-app> 

而且我爲spring-servlet.xml也在WEB-INF

<?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:mvc="http://www.springframework.org/schema/mvc" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 

    <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure --> 

    <!-- Scans within the base package of the application for @Components to configure as beans --> 
    <!-- @Controller, @Service, @Configuration, etc. --> 
    <context:component-scan base-package="com.bidapp.controllers" /> 

    <!-- Enables the Spring MVC @Controller programming model --> 
    <mvc:annotation-driven /> 
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/jsp/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 
</beans> 

我的我啓動應用程序並導航到http://localhost:8080/BidApp/hello，它給了我一個404。是我的xml文件在錯誤的地方，或者我錯過了一些配置參數？有沒有一個好的地方可以查看所有可用的參數來配置Spring應用程序。春季框架的參考，除非我讀錯了，沒有幫助。

Answer 1

當您添加<mvc:annotation-driven />到您的配置，您必須使用類似這樣的

<url-pattern>/</url-pattern> 

URL模式，它取代處理器映射和處理程序適配器的默認設置，而這些違約是該處理的OLD-的那些樣式控制器。

我認爲你應該理解component-scan和annotation-config之間的區別。如果你使用掃描，那麼你不需要使用配置。 Difference between <context:annotation-config> vs <context:component-scan>

請不要用你的舊代碼執行與拆卸<mvc:annotation-driven />

（一般）將不mvcdefault servlethandler

Answer 2

調度器具有一個無效的映射。只接受1個通配符。

因此改變調度匹配網址爲類似/*

所以/*.do或/*.htm*.html但不/*.jsp比如Tomcat如果你想休息一下網址已有映射.jsps

，我可能會建議使用UrlRewriteFilter？它的使用非常簡單，可以像使用Apache重寫過濾器一樣使用。

Answer 3

更改URL的模式<url-pattern>/</url-pattern>甚至工作是/不是足夠。在我的春天-servlet.xml文件我是缺少一些元素：

<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure --> 
<!-- This tag allows for mapping the DispatcherServlet to "/" (all extensions etc)--> 
<mvc:default-servlet-handler/> 


<!-- Enables many annotations and searches for @Controller annotated methods etc.. --> 
<context:annotation-config /> 

一旦這些添加，相應的控制器被發現（基於註解），並在適當的URI開始/執行。
