javajavax。埃尔。SpringWeb应用中jsp中的PropertyNotFoundException，即使存在属性
我是SpringMVC新手，对javax的错误有点迷茫。埃尔。PropertyNotFoundException是我当前在第一个测试应用程序中获取的。 我试图显示一个人员列表，然后按下一个按钮进入一个新页面，要求输入新的人员详细信息
所以我选了个人模特
public class Person {
private String firstName;
private String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
每当用户请求新的人员条目时，就会调用addPersonInitial方法。此后，当用户填写表单时，提交由函数addPersonFinal处理。该函数应添加新条目并重定向回显示已有人员列表的页面
@Controller
@RequestMapping(value="person")
public class PersonController{
@Autowired
private PersonService personservice;
@RequestMapping(value="viewAll", method=RequestMethod.GET)
public ModelAndView viewAll() {
ModelAndView mav = new ModelAndView();
mav.setViewName("viewAll");
mav.addObject("persons", personservice.getAllPersons());
return mav;
}
@RequestMapping(value="addPersonInitial", method = RequestMethod.GET)
public ModelAndView addPersonInitial() {
ModelAndView mav = new ModelAndView();
mav.setViewName("addPersonInitial");
mav.addObject("person", new Person());
return mav;
}
@RequestMapping(value="addPersonFinal", method = RequestMethod.POST)
public ModelAndView addPersonFinal(@ModelAttribute(value="person") Person person) {
this.personservice.addPerson(person);
return this.viewAll();
}
}
jsp中的代码是
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Add Person Initial</title>
</head>
<body>
<table>
<tbody>
<form:form method="POST" action="addPersonFinal" commandName="person">
<tr>
<td><label for="firstName">First Name: </label><form:input path= "firstName" /> </td>
<td><label for="lastName">Last Name: </label><form:input path="lastName" /></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="Add" /></td>
</tr>
</form:form>
</tbody>
</table>
</body>
</html>
当用户为新用户提交表单数据时，我得到以下错误
