启用 Spring MVC 处理请求

Question

大家好我一直在处理这个问题，我找不到解决方案浏览希望你能帮助我。无论我对控制器 web.xml 或 search-customer-context.xml 做了多少更改，我都会收到 "HTTP Status 404 - /SearchCustomerID/search.jsp"。希望你能帮助解决这个问题。这是我的文件。 web.xml

SearchController.java

@控制器 public class 搜索控制器 {

@RequestMapping("/SearchCustomerID/search")
public String searchInformation(@Valid @ModelAttribute("userInfo") UserInfo userInfo){
    System.out.println("Controller reached");
    System.out.println("Name: "+userInfo.getName());
    return "search";
}

}

对不起大家我的错。问题是我已经将 web.xml 配置为 <url-pattern> 设置为 *html 但我的请求始终是 *.jsp 所以显然我不匹配。现在我更改了 URL 并且我能够通过注释为 Controller 的 class。
