未调用Spring MVC Controller [英] Spring MVC Controller not called
问题描述
我是Web开发的初学者，并尝试创建一个简单的spring mvc应用程序.
I'm beginner in web development and try to create a simple spring mvc application.
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

version="3.1">

<context-param>
<param-name>contextConfigLocation</param-name>

</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-dispatcher-servlet.xml
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"

<mvc:annotation-driven/>

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);
}
}
我编写的所有内容都与我的教程一样正确，但仍然出现 404 tomcat 8.5RC 错误.我没有调用控制器方法.
I have written everything correct like my tutorial but still get 404 tomcat 8.5RC error. I thing controller method is not called.
我添加了 spring 4 libs ，我觉得一切都很好，但是在Intellij IDEA中看不到 Hi 输出.
I have add spring 4 libs and I thing everything was fine but I don't see Hi output in Intellij IDEA.
hello.jsp
hello.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>one</title>
</head>
<body>
Hello World
${message}
</body>
</html>
运行tomcat时，我看到我的 index.jsp 页...但是当尝试进入 http://localhost:8000/hello.do 时，得到> 404 错误:(
I see my index.jsp page when tomcat is run ... but when try to go http://localhost:8000/hello.do getting 404 error :(
推荐答案
首先，我将首先扫描一个基本软件包，而不是两个.像这样从路径中删除 controller 映射:
First I would start by scanning only one base package instead of two. Remove the controller map from the path aswel Like this:
<context:component-scan base-package="org.test.test"/>
除去以下内容，因为只有一个就足够了.您不需要两个.
Get rid of the following because only one will suffice. You dont need two.
<context:component-scan base-package="org.test.test.model"/>
并按如下所示修改您的属性值:
And modify your property value as follows:
<property name="prefix">
<value>/WEB-INF/</value>
</property>
