java - Spring MVC 与 Maven

Question

我创建了一个 Maven Web 项目

通过porm.xml添加maven依赖使用Spring Bean配置Xml文件在文件夹WEB-INF/config中创建了servelet-config.xml创建了一个文件夹 src\main\java 并在该文件夹中创建了一个 HelloController 类。现在，当我在 HelloController 类中使用 @Controller 注释时，无法解析。我不知道当我在 serverlet-config.xml 中使用时，它显示:

Configures the annotation-driven Spring MVC Controller programming model. Note that this tag works in Web MVC only, not in Portlet MVC!

我正在关注.... https://www.youtube.com/watch?v=9MdnvleI6-8

我创建的 web.xml 是:

`<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
     
  
  <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
	<servlet>
		<servlet-name>springDispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/config/servlet-config.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>*jsp</url-pattern>
	</servlet-mapping>
	
</web-app>
`

我的 porm.xml 是

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

我的 servlet 配置是:

<mvc:annotation-driven/>
<context:component-scan base-package="com.sat.controllers"></context:component-scan>



</beans>

我的 Controller 类是:

package com.sat.controllers;

import javax.annotation.Resource;

import org.springframework.web.servlet.config.annotation.EnableWebMvc;



@EnableWebMvc
@Controller

public class HelloController {
	
	

}

我做错了什么？请帮忙...

Answer 1

您的 pom.xml 指定了 Spring 1.2.x - 这是一个非常旧的版本，并且肯定不支持任何类型的注释 - 您从哪里获得该 POM 片段？

Spring 已经到了 4.1.x，如果你想学习，你应该使用它。
