Spring MVC-HTTP状态404-原始服务器未找到目标资源的当前表示形式

Question

尝试创建Spring MVC Hello World Web应用程序。它当前正在返回HTTP状态404。404表示找不到文件，但是我不确定为什么。我认为我的servlet.xml指向适当的文件夹（component-scan）。我认为所有文件都正确命名（没有错别字）。看到图片中的错误。

servlet.xml

$(document.body).on("click", ".checkbox", function() {
  $(this).remove();
});

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>

hello-world.jsp

package helloworld;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloWorldController {

    @RequestMapping("/")
    public String showPage() {
        return "hello-world";
    }
}

Answer 1

servlet.xml和web.xml不在WEB-INF下。

Answer 2

RequestMapping在控制器中指向“ /”。尝试拨打http://localhost:8080/
