确保你的Spring表单提及@H_704_1@modelattribute="<Model Name"。
例：
@Controller
@RequestMapping("/greeting.html")
public class GreetingController {
@modelattribute("greeting")
public Greeting getGreetingObject() {
return new Greeting();
}
/**
* GET
*
*
*/
@RequestMapping(method = RequestMethod.GET)
public String handleRequest() {
return "greeting";
}
/**
* POST
*
*
*/
@RequestMapping(method = RequestMethod.POST)
public ModelAndView processSubmit(@modelattribute("greeting") Greeting greeting, BindingResult result){
ModelAndView mv = new ModelAndView();
mv.addObject("greeting", greeting);
return mv;
}
}
在你的JSP中：
<form:form modelattribute="greeting" method="POST" action="greeting.html">
