獲取HTTP狀態500 - servlet.init（）爲servlet調度器拋出異常

我試着寫一個spring mvc的演示，我想要做的就是在index.jsp中輸入一些內容，然後提交它。當控制器收到時，它會轉到showResult.jsp來顯示我在index.jsp中提交的內容。但是當我點擊提交按鈕時，我總是出錯。該頁面顯示HTTP狀態500獲取HTTP狀態500 - servlet.init（）爲servlet調度器拋出異常

下面是web.xml中：

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

    <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>*.do</url-pattern> 
    </servlet-mapping> 


</web-app>

這裏是小服務程序的xml：

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


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

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

</beans>

這裏是JSP，我輸入的東西在裏面，並提交它：

<%@ page contentType="text/html;charset=UTF-8" language="java" %> 
<html> 
    <head> 
    <title>sublit</title> 
    </head> 
    <body> 
    <h1>input and sublit</h1> 
    <form action="test/one.do"> 
     <input type="text" name="userName"> 
     <input type="submit" value="submit"> 
    </form> 
    </body> 
</html>

這裏是控制器：

package com.work.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.Model; 
import org.springframework.web.bind.annotation.RequestMapping; 

@Controller 
@RequestMapping(value = "test") 
public class TestController { 

    @RequestMapping("one") 
    public String getUserName(String userName, Model model){ 
     System.out.println(userName); 
     model.addAttribute("msg", userName); 
     return "showResult"; 
    } 
}

這裏是爲了展示我的提交頁面：

<%@ page contentType="text/html;charset=UTF-8" language="java" %> 
<html> 
<head> 
    <title>show result</title> 
</head> 
<body> 
    ${msg} 
</body> 
</html>

錯誤：

最後我解決這個問題。點是servlet xml的前端：

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

它由IntelliJ自動構建。但它不是完整版本。我修改爲：

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

它的工作原理！
