问题描述
这是我的表格:
<form action="${pageContext.request.contextPath}/admin/editc" method="POST" id="editForm">
<input type="text" name="username" class="form-control" />
<input type="text" name="password" class="form-control" />
<input type="submit" value="submit" >
</form>
这是我的控制器方法:
@RequestMapping(value = "/admin/edit", method = RequestMethod.GET)
public ModelAndView editPage() {
ModelAndView model = new ModelAndView();
model.addObject("title", "User edit Form - Database Interaction");
model.addObject("message", "This page is for ROLE_ADMIN only!");
model.setViewName("editpage");
System.out.println("getting edit page");
return model;
}
@RequestMapping(value = "/admin/editc", method = RequestMethod.POST)
public ModelAndView updateCredentials() {
// System.out.println("Username= "+username+" password= "+password);
ModelAndView model = new ModelAndView();
model.addObject("title", "Credential Edit Operation");
model.addObject("message", "You are successfully updated your credentials");
model.addObject("edited", "TRUE");
model.setViewName("editpage");
System.out.println("executed updateCredentials POST method");
return model;
}
现在的问题是,我在控制台中收到405错误,如下所示:
Now the issue is I am getting 405 error in console like below:
org.springframework.web.servlet.PageNotFound handleHttpRequestMethodNotSupported
WARNING: Request method 'POST' not supported
任何人都可以帮助我解决此错误吗?
Can any one please help me resolving this error ?
推荐答案
您首先需要使用GET方法显示表单,并需要使用POST提交表单.
You first need a GET method to display the form and a POST to submit it.
@RequestMapping(value = "/admin/editc", method = RequestMethod.GET)
public ModelAndView updateCredentials() {
return new ModelAndView("editPage");
}
@RequestMapping(value = "/admin/editc", method = RequestMethod.POST)
public ModelAndView updateCredentials(@ModelAttribute UserCredentials credentials) {
someService.save(credentials);
...
}
