spring mvc 使用@InitBinder接收表单多对象

 

用Spring MVC 接收表单多对象的时候用@InitBinder

@Controller
public class HelloController extends BaseController{
    @InitBinder("teacher")
    public void initBinder1(WebDataBinder binder){
        binder.setFieldDefaultPrefix("teacher.");
    }
    @InitBinder("student")
    public void initBinder2(WebDataBinder binder){
        binder.setFieldDefaultPrefix("student.");
    }    
    
    //URL映射
    @RequestMapping(value="/save", method = RequestMethod.POST)
    public ModelAndView save(Teacher teacher,Student student) {
        System.out.println(teacher.getName()+" "+student.getName());
        return null;
    }
