您好我正在开发我的第一个春季mvc应用程序。我正在尝试向db添加表单。为此我使用@ModelAttribute并且它无法正常工作。
我的控制器：
@Controller
public class AddKPI {
@RequestMapping("/getAddKPIForm")
public ModelAndView addKPI(){
ModelAndView modelAndView = new ModelAndView("getAddKPIForm","kpi", new KPI());
String auditInfo = "User : "+getCurrentDateInStringFormat_YYYYMMDD_HHSSMM();
modelAndView.addObject("auditInfo",auditInfo);
return modelAndView;
}
@RequestMapping(value="/addKPITODB")
public ModelAndView add2DB(@ModelAttribute("kpi") KPI kpi){
System.out.println("In controller Method");
System.out.println("kpi.getKpi_name() = "+kpi.getKpi_name());
return new ModelAndView("adding_Success");
}
public static String getCurrentDateInStringFormat_YYYYMMDD_HHSSMM() {
String date_Str = null;
try {
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
date_Str = sdf.format(date);
} catch (Exception pe) {
// TODO: Add catch code
pe.printStackTrace();
}
return date_Str;
}
}
我的表格代码：
<div align="center">

当我点击提交按钮时，它不会转到控制器方法＆＃34; / addKPITODB＆＃34;我收到404错误（网址为http://localhost:6006/EasyRUN/addKPITODB）。如果我删除@ModelAttribute，它将转到控制器方法。我在做什么错。请纠正我。
非常感谢您的帮助。谢谢。

我使用您的代码创建了一个示例项目，该工作正常：
