试图从这个链接学习弹簧：

http://viralpatel.net/blogs/spring-3-mvc-create-hello-world-application-spring-3-mvc/

但是收到以下错误：

    type Exception report

    message Servlet execution threw an exception

    description The server encountered an internal error that prevented it from fulfilling this request.

    exception

   javax.servlet.ServletException: Servlet execution threw an exception
    org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java:238)

    javax.servlet.http.HttpServlet.service(HttpServlet.java:617)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:723)

在浏览器和eclipse控制台上重复多次重复错误。

The dir structure is

文件内容如下： 的web.xml 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

    <welcome-file-list>

    </welcome-file-list>

 <servlet>
 <servlet-name>spring</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 </servlet>
 <servlet-mapping>
 <servlet-name>spring</servlet-name>
 <url-pattern>/</url-pattern>
 </servlet-mapping>

</web-app>

弹簧servlet.xml中

   <beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="

        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">


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

        <bean id="viewResolver"
            class="org.springframework.web.servlet.view.UrlBasedViewResolver">
            <property name="viewClass"
                value="org.springframework.web.servlet.view.JstlView" />
            <property name="prefix" value="/" />
            <property name="suffix" value=".html" />
        </bean>
    </beans>

控制器是：

@Controller
public class HomeController {

    @RequestMapping("/StartPage")
    public ModelAndView springContoller(){
        String message = "Hey welcome to Spring 3.0!! ";
        System.out.println("in controller");
        return new ModelAndView("StartPage","message",message);
    }
}

的index.jsp 

</head>
<body>
<a href="StartPage.html">Click here </a>
</body>
</html>

这个问题是由于混合了弹簧罐。我遇到了同样的问题。从pom.xml中删除了一些罐子并且它有效。 这是我原来的pom.xml。使用Spring 4 Hibernate 4的基础项目

        <org.springframework-version>4.0.3.RELEASE</org.springframework-version>

</dependencies>

删除了以下依赖项，它运行良好

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>

更新的答案： -

添加网址映射：

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

这应该可以胜任。

答案 1 :(得分：0)

浪费了5个小时:(

任何人都可以告诉我为什么以下代码不起作用：

 <property name="prefix" value="/WEB-INF/html/" />
        <property name="suffix" value=".html" />

但如果我将其更改为：

   <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />

它工作正常。修改后的目录结构为：

enter image description here

为什么它没有拿起html文件并抛出 在DispatcherServlet 中找不到带有URI的HTTP请求和使用JSP的工作文件的映射。

答案 2 :(得分：0)

尝试更新该部分代码并尝试

 <servlet-mapping>
 <servlet-name>spring</servlet-name>

 //Use this 
 <url-pattern>/*</url-pattern>

That is not correct
<url-pattern>/</url-pattern>

 </servlet-mapping>

更新

尝试添加此

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.html</url-pattern>
  </servlet-mapping>
  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.jsp</url-pattern>
  </servlet-mapping>
