我有形式person.jsp：

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%> 
<html> 
<head> 
<title>Person form</title> 
</head> 
<body> 
    <form method="POST" action="addPerson.html"> 

     <form:label path="name"></form:label> 

     <form:label path="lastName"></form:label> 

     <form:label path="age"></form:label> 

     <input type="submit" value="Add Contact" /> 

    </form> 


</body> 
</html>

而且CONTROLER：

@Controller 
public class FormControler { 

    @RequestMapping(value="/addPerson", method = RequestMethod.POST) 
    private void contrler(@ModelAttribute("person")Person person, BindingResult result) { 

     System.out.println("Name "+person.getName()); 

    } 
    @RequestMapping(value="/person", method = RequestMethod.GET) 
    public ModelAndView showContscts() { 

     return new ModelAndView("person", "command", new Person()); 
    } 

}

而且Person.java：

public class Person { 

    private String name; 
    private String lastName; 
    private String age; 

    public String getName() { 
     return name; 
    } 
    public void setName(String name) { 
     this.name = name; 
    } 
    public String getLastName() { 
     return lastName; 
    } 
    public void setLastName(String lastName) { 
     this.lastName = lastName; 
    } 
    public String getAge() { 
     return age; 
    } 
    public void setAge(String age) { 
     this.age = age; 
    } 


}

而且index网站王氏<a href：

<!DOCTYPE html> 
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%> 
<html> 
<body> 

    <a href="person">Person</a> 

</body>

我这个主题中使用建议解决我的问题，但我我也将ModelAndView("person", "command", new Person())中的名字从command更改为person。

你有你的窗体绑定到模型中，这种方式：

<form:form method="POST" action="addPerson.html" modelAttribute="person"> 
    <form:label path="name"></form:label> 
    <form:label path="lastName"></form:label> 
    <form:label path="age"></form:label> 
    <input type="submit" value="Add Contact" /> 
</form: form>

我编辑窗体，但我仍然看到这个相同的exeption。 – user902691

只是为了确认你使用'form：form'标签而不是'form'直接对吗？ –

是的，我改成'form：form'并添加'modelAttribute'。 – user902691

你有你的JSP文件构成：假设JSP名称是person.jsp

<form:form method="POST" action="addPerson" modelAttribute="person"> 
    <form:label path="name"></form:label> 
    <form:label path="lastName"></form:label> 
    <form:label path="age"></form:label> 
    <input type="submit" value="Add Contact" /> 
</form: form>

现在从您的person.jsp是加载应该是这样的操作方法：

@Controller 
public class FormControler { 

    @RequestMapping(value="/addPerson", method = RequestMethod.POST) 
    private void contrler(@ModelAttribute("person")Person person, BindingResult result) { 
     System.out.println("Name "+person.getName()); 
    } 

    // Your this method is going to show pseron jsp page 
    // dont return model and view, instead try this 

    @RequestMapping(value="/person", method = RequestMethod.GET) 
    public String showContacts(Model model) { 
     // your jsp demands Person.java as modelAttribute 
     // add that POJO in model and send along with your jsp 

     model.addAttribute("person", new Pseron()); // this attribute name should be same as it is in modelAttribute of jsp form 
     return "person"; 
    } 
}

试试看。
