我正在尝试制作一个简单的表单并使用 Spring MVC 提交它。我尝试了多种方法来实现它，所有页面都映射到 web.xml 上，并且我检查它是否使用简单页面进行导航。但是当单击按钮时，我收到以下错误:
HTTP Status 404 – Not found
Type Status Report
Message /addEmployee
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Apache Tomcat/9.0.20
employeeHome.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<title>Cadastro</title>
</head>
<body>
<h1>Cadastro</h1>
<form:form method="POST" action="/addEmployee" modelAttribute="employee">
<table>
<tr>
<td><form:label path="name">Name</form:label></td>
<td><form:input path="name"/></td>
</tr>
<tr>
<td><form:label path="id">ID</form:label></td>
<td><form:input path="id"/></td>
</tr>
<tr>
<td><form:label path="contactNumber">Contact Number</form:label></td>
<td><form:input path="contactNumber"/></td>
</tr>
<tr>
<td><input type="submit" value="Submit"/></td>
</tr>
</table>
</form:form>
</body>
</html>
Controller :SpringMVCHelloWorld
@Controller
public class SpringMVCHelloWorld {
// Employee
@GetMapping("/employeeHome")
public ModelAndView showForm() {
return new ModelAndView("employeeHome", "employee", new Employee());
}
@RequestMapping(value = "/addEmployee", method = RequestMethod.POST)
public String addEmployee(@ModelAttribute("employee") Employee employee, BindingResult result, ModelMap model) {
if(result.hasErrors()) {
return "error";
}
model.addAttribute("name",employee.getName());
model.addAttribute("contactNumber",employee.getContactNumber());
model.addAttribute("id", employee.getId());
return "employeeView";
}
}
我认为问题是在 .jsp 页面和 @RequestMapping(value = "/addEmployee", method = RequestMethod.POST) 方法上设置 action ，但我不知道出了什么问题。
编辑:问题已解决
改变
<form:form method="post" action="/addEmployee" modelAttribute="employee">
到
<form:form method="post" action="addEmployee" modelAttribute="employee">
最佳答案
我认为问题可能出在操作 URL
你可以这样尝试
<form:form method="POST" action="${pageContext.request.contextPath}/addEmployee" modelAttribute="employee">
或者硬编码baseUrl(如果有的话)
<form:form method="POST" action="baseContextPath/addEmployee" modelAttribute="employee">
