PageNotFound：在DispatcherServlet中找不到具有URI的HTTP請求的映射

與DispatcherServlet有問題，我認爲問題出現在xml中的一個，但在Spring中是新的，我無法識別它。PageNotFound：在DispatcherServlet中找不到具有URI的HTTP請求的映射

HotelController.java（SRC \主\的java \大全\控制器）

@Transactional 
@Controller 
public class HotelController { 

    @Autowired 
    HotelService hotels; 

    @RequestMapping(value="/hotels", method=RequestMethod.GET) 
    public String index(Model model) { 
     System.out.println("test"); 
     model.addAttribute("hotels", hotels.findAllHotels()); 
     return "allhotels"; 
    } 
}

我曾經在的觀點：「\ SRC \主\ web應用\ WEB-INF \ views「，我有一個名爲」allhotels.jsp「的文件，我試圖用」http://localhost:8080/hotels「打開頁面（儘管我不確定這是否正確）。

上面的文件名前面是它們的相對路徑。

我使用Maven的Spring引導。如果您需要我發佈其他內容，請告訴我。

如果https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-web-jsp/src/main/webapp/WEB-INF/jsp是對的，也許把它放在'\ jsp'而不是'\ views'中？ – zapl

@zapl對不起，我忘了包含mvc-dispatcher-servlet.xml。我嘗試將文件夾名稱和xmp更改爲jsp，但它不起作用。 – Aterin

我可以看到你已經使用了兩個不同的名字，而DispatcherServlet的web.xml中配置它

<servlet> 
    <servlet-name>mvc-dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <init-param> 
      <param-name>contextConfigLocation</param-name> 
      <param-value>/WEB-INF/spring/appServlet/mvc-dispatcher-servlet.xml</param-value> 
     </init-param> 
     <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
     <servlet-name>mvc-dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
</servlet-mapping>

不要在你的MVC-調度-servlet.xml中

<?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" 
    xmlns:jee="http://www.springframework.org/schema/jee" xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:tx="http://www.springframework.org/schema/tx" 
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd  http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd 
    http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"> 

<context:component-scan base-package="hotelbooking.controller"/> 
<mvc:annotation-driven /> 

</beans>

我下面的變化覺得它更多關於web.xml和spring配置文件問題，請嘗試使用上面修改過的並嘗試一次。

URL模式應該像下面

http://hostname:port/<webapplication-name>/<controller-path> http://localhost:8080/hotelbookings/hotels（在你的情況下，嘗試這種假設 'hotelbookings' 爲Web應用程序的名稱。）

感謝您的回答，但仍然一樣。爲了確保，Web應用程序名稱是pom.xml上的artifactid /名稱？ – Aterin

啊對，那的確是酒店預訂。 – Aterin

的確，我確實是這樣，錯誤是：'沒有爲名爲'dispatcherServlet'的DispatcherServlet中帶有URI [/ hotelbookings/hotels]的HTTP請求找到映射。「 – Aterin

你可能會丟失這部分在mvc-dispatcher-servlet.xml文件

<context:component-scan base-package="hotelbooking.controller" />

我想我看到了這個問題。你已經使用了值而不是路徑。嘗試使用這樣的：

@RequestMapping(path="/hotels", method=RequestMethod.GET)

感謝您的回答，但我添加了該行，但沒有幫助，我認爲如果這是由於依賴性問題導致應用程序無法啓動的問題。我確實決定離開''以供將來打樣。 – Aterin

只是注意到你的編輯。我發現所有的例子都使用'value'，不管我用'path'嘗試過，但它仍然不起作用。 – Aterin
