Spring MVC问题。如何从两个或多个对象创建视图？

将对象包装在包装器表单类中，然后将其传递给模型。

public class MyForm{   public user;   public address;   // getters, setters, etc.}

然后

ModelAndView mav = new ModelAndView(); // ModelAndViewmav.addObject("myForm", new MyForm()); // e.g.

在您的模型中，地址应该附加到用户吗？换句话说，在我看来，与

User

Address

@Entity@Table(name = "user")public class User{   @Id @Column(name="user_id")   public Long id;   @oneToMany   @JoinColumn(name = "user_id") // so the address table would have a user_id foreign key   public Address address;}
