如何设置相关类的属性Spring MVC中

我有两个实体类：用户和地址用户等级：它具有许多其他特性加上相关类地址如何设置相关类的属性Spring MVC中

Entity 
@Table(name = "T_USER_DETAILS") 
public class User { 


//@GenericGenerator(name = "generator",strategy = "sequence-identity",parameters = { @Parameter(name = "sequence",value = "USER_ID_SEQ")}) 

@GenericGenerator(name = "generator",strategy = "increment")  
@Id 
@GeneratedValue(generator = "generator") 
@Column(name = "USER_ID") 
private int userid; 

@Column(name = "USER_FIRSTNAME") 
private String firstname; 
@Column(name = "USER_AGE") 
private int age; 


//creating many to one relationship between address class and student class 
@ManyToOne(cascade = CascadeType.ALL) 
@JoinColumn(name = "ADDRESS_ID") 
private Address address;

这里的地址类也是一个enity

@Entity 
@Table(name = "T_ADDRESS_DETAILS") 
public class Address { 



    @GenericGenerator(name = "idgenerator", strategy = "increment") 
    @Id 
    @GeneratedValue(generator = "idgenerator") 
    @Column(name = "ADDRESS_ID") 
    private int addressId; 

    @Column(name = "ADDRESS_LINE1") 
    private String address_line1; 

    @Column(name = "ADDRESS_LINE2") 
    private String address_line2;

在我的形式，我创建的用户类的命令豆，在我的控制器类绑定它：

<form:form method = "post" action = "register.html" commandName = "newUser"> 

<br> 
<h2><i>Create new account</i></h2> 
<br> 
Enter the firstname<br> 
<input type = "text" size = "30" name = "firstname"> 
<font color = "red"> <form:errors path = "firstname" cssClass = "error"/></font><br> 
Enter the lastname<br> 
<input type = "text" size = "30" name = "lastname"> 
<font color = "red"> <form:errors path = "lastname" cssClass = "error"/></font><br> 
Enter the password<br> 
<input type = "password" size = "30" name = "password"> 
<font color = "red"> <form:errors path = "password" cssClass = "error"/></font><br> 
Enter the Email Id<br> 
<input type = "text" size = "30" name = "emailId"> 
<font color = "red"><form:errors path = "emailId" cssClass = "error"/><br></font> 
Enter the phone number<br> 
<input type = "text" size = "30" name = "phonenumber"> 
<font color = "red"><form:errors path = "phonenumber" cssClass = "error"/></font><br> 
Enter the age<br> 
<input type = "text" size = "30" name = "age"/> 
<font color = "red"><form:errors path = "age" cssClass = "error"/></font><br><br> 

Enter the Address<br> 
<input type = "textbox" name = "address" size = "30"> 
<font color = "red"><form:errors path = "address" cssClass = "error"/></font><br> 

<div align = "center"> 



<input type = "submit" name = "submit" value = "submit">

控制器：

@RequestMapping(method = RequestMethod.POST) 
public String register(@ModelAttribute("newUser") User user,BindingResult result,Model model,HttpSession session,HttpServletRequest request) //retrieve the backing bean with in the user attribute 
{ 
.. 
}

这里我的问题是我如何分配，我想从像城市，州，国家... 形式发送地址类的属性，我需要做什么样的变化我的jsp页面和我的控制器类。请帮忙。

你也可以用加盟类的属性的关联使用<form:input标签如下所示：

<form:form commandName="person" method="post" action="${formAction}"> 
    <div class="form"> 
     <p>User</p> 
      <form:input path="firstname" /> 
      <form:input path="address.address_line1" /> 

      <input type="submit" class="btn btn-primary" /> 
    </div> 
</form:form>

记住，关键是要使用表单输入路径来匹配联接类的属性。然后，您可以将此方法用于表单bean中使用的所有其他关联。

您应该更改地址bean以为City，State等添加属性（其中还包括使用注释提供的良好验证）。此后，您将不得不将输入拆分为地址bean的每个属性;然后，您可以使用sping:bind标签与符号address.city

<form:form commandName="person" method="POST" action = "register.html"> 

    <spring:bind path="address.city"> 
    <input type = "textbox" name = "address.city" size = "30"> 
    </spring:bind> 

    ... 
    ... 
</form:form>
