[在此处输入图像描述][1][在此处输入图像描述][1]我正在尝试创建 Maven + Spring Web 演示项目。为此,我创建了一个 index.jsp,我试图用值作为我的名字来点击控制器。但是在运行应用程序之后,即使我得到了索引页面,如果我点击超链接来点击我的控制器,我会立即得到请求的资源不可用。我是 Maven 和 Spring 的新手。请帮助解决这个问题。

我的 POM.xml 是,

import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {
String message = "Welcome to Spring MVC!";

@RequestMapping(value="/hello", method = RequestMethod.GET)
public ModelAndView showMessage(
        @RequestParam(value = "name", required = false, defaultValue = "World") String name) {
    System.out.println("in controller");

    ModelAndView mv = new ModelAndView("helloworld");
    mv.addObject("message", message);
    mv.addObject("name", name);

尝试将您的 dispatcher-servlet 配置更新为如下内容:

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

use-default-filtersxsd 中的文档说:

指示是否应启用对使用 @Component、@Repository、@Service 或 @Controller 注释的类的自动检测。默认为“真”。
