我是网络开发的初学者,并尝试创建一个简单的spring mvc应用程序。
的web.xml
<?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">
<display-name>Spring Web MVC Application</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
</context-param>
<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>
MVC-调度-servlet.xml中
<?xml version="1.0" encoding="UTF-8" ?>
<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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="

控制器
@Controller
@Scope(value = "singleton")
public class T1Controller {
@RequestMapping(value = "/hello.do")
public ModelAndView helloWorld() {
System.out.print("Hi");
String message = "Hello World, Spring 3.0!";
return new ModelAndView("hello", "message", message);
}
}
我写的一切都像我的教程一样正确,但仍然出现404 tomcat 8.5RC
错误。我没有调用控制器方法。
我添加了spring 4 libs
,我认为一切都很好,但我没有在Intellij IDEA中看到Hi
输出。
的hello.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>one</title>
</head>
<body>
Hello World
${message}
</body>
</html>
我在运行tomcat时看到index.jsp
页面...但是当试图http://localhost:8000/hello.do
出现404
错误时:(
答案 0 :(得分:0)
首先,我将首先扫描一个基本包而不是两个。从路径aswel中删除控制器地图,如下所示:
<context:component-scan base-package="org.test.test"/>
摆脱以下因为只有一个就足够了。你不需要两个。
<context:component-scan base-package="org.test.test.model"/>
并修改您的属性值,如下所示:
<property name="prefix">
<value>/WEB-INF/</value>
</property>
