Question

我创建了一个非常小的弹簧网络应用程序但是无法使用eclipse在tomcat上部署它。我可以在日志中看到Web应用程序被初始化。但是tomcat实际上并没有部署它，如果我尝试去URL，我会得到404错误资源不可用。我在这里错过了什么吗？

Web xml

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
        http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

       <servlet>
          <servlet-name>MNPUI</servlet-name>
          <servlet-class>
             org.springframework.web.servlet.DispatcherServlet
          </servlet-class>
          <load-on-startup>1</load-on-startup>
       </servlet>

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

       <welcome-file-list>
            <welcome-file>
                home.jsp
            </welcome-file>
       </welcome-file-list>
</web-app>

MNPUI-servlet.xml中

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

        <context:component-scan base-package="com.doyleisgod.mnpui.controllers"/>

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

    </beans>

的HomeController

package com.doyleisgod.mnpui.controllers;

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

@Controller
public class HomeController {
    @RequestMapping("/home.jsp")
    public String home (ModelMap model){
        model.addAttribute("message", "Welcome");
        return "home";
    }
}

针对home.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Home</title>
</head>
<body>
${message}
</body>
</html>

Answer 1

您需要将以下行添加到web.xml文件

<servlet-mapping>
        <servlet-name>jsp</servlet-name>
        <url-pattern>/WEB-INF/jsp/*</url-pattern>
</servlet-mapping>

大多数servlet容器都有一个从*.jsp到它们自己的JSP处理器的默认映射。
