GET/springmvc/form.jsp没有映射

Question

我正在尝试使用spring MVC。我的问题是，在我的控制器中没有请求映射工作，只有我的主页链接：“/”工作。

@Controller
public class HelloWoldController {

     @RequestMapping("/")
    public String showPage() {
        return "main";
    }


    @RequestMapping("/showForm")
    public String showForm() {
        return "form";
    }

}

我的web.xml文件是：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    id="WebApp_ID" version="3.1">

    <servlet-mapping>

我也遇到了同样的问题，我做了以下工作：清理您的项目：在eclipse中，转到Project-->clean，右键单击project并刷新它。
