Spring - 在DispatcherServlet中找不到映射，請求URI包含應用程序名稱

Question

我試圖從頭構建一個Spring應用程序，並且使用以下目錄結構和文件製作了一個簡單的應用程序。

的web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> 

    <display-name>LearningSpring</display-name> 
    <welcome-file-list> 
    <welcome-file>index.html</welcome-file> 
    </welcome-file-list> 

    <servlet> 
    <servlet-name>dispatcher</servlet-name> 
    <servlet-class> 
     org.springframework.web.servlet.DispatcherServlet 
    </servlet-class> 
    <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/*</url-pattern> 
    </servlet-mapping> 

</web-app> 

調度-servlet.xml中

<mvc:annotation-driven/> 
<context:component-scan base-package="com.learn.spring.app.web" /> 

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <property name="prefix" value="/WEB-INF/jsp/"/> 
    <property name="suffix" value=".jsp"/> 
</bean> 

CentralController.java

@Controller 
public class CentralController { 

    @RequestMapping("/profile.html") 
    public ModelAndView showProfile(HttpServletRequest request, HttpServletResponse response){ 
     return new ModelAndView("profile"); 
    } 
} 

我不明白髮生了什麼事錯在上面的代碼，但我總是得到一個404錯誤。將tomcat日誌顯示，我注意到以下

一件事是，所有的請求的URI有/LearningSpring/（應用程序名稱）作爲前綴（我想應該不會有）。

我無法通過網址localhost:8080/LearningSpring/profile.html訪問profile.jsp頁面，也沒有顯示index.html作爲歡迎頁面。它只是拋出404當我訪問localhost:8080/LearningSpring/

我已經通讀了很多答案和谷歌搜索幾個小時，但沒有運氣。請幫助指出什麼是錯的。

謝謝

夫婦的事情... ...調度的servlet爲 「/」 的

1. 更改URL模式;

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

即成所有靜態資源通過調度器的servlet;

<mvc:resources location="/**" mapping="/"></mvc:resources>

檢查該樣品的例子 - https://github.com/code-4-fun/spring-mvc-demo/blob/master/src/main/webapp/WEB-INF/dispatcher-servlet.xml
