Java 将spring表单映射到会话对象

我有一个基本表单，我从sessionBean.person.xxxxx获得了我的值（所以一切正常）：

sessionBean是：

@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class SessionBean implements Serializable {
    private static final long serialVersionUID = 9139554982970790165L;
    private final String id = UUID.randomUUID().toString();
    private Person person = null;
    private String redirect=null;
    private Order3d order3d=new Order3d();
    //getter and setters
}

我的个人课程是：

@Entity
@Table (name="person")
public class Person implements Serializable {
    private static final long serialVersionUID = 3005461811554821039L;
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column (name="id")
    private int id;
    @Column (name="email")
    private String email;
    @Column (name="company")
    private String company;
    @Column (name="siret")
    private long siret;
    @Column (name="payment")
    private String payment;
    @Column (name="title")
    private String title;
    @Column (name="firstname")
    private String firstname;
    @Column (name="lastname")
    private String lastname;
    @Column (name="password", columnDefinition="char", length=64)
    private String password;
    @Column (name="phone")
    private String phone;
    @Column (name="fax")
    private String fax;
}

当我在控制器中获取Person对象时，sessionBean.peron中的键入值不会更新（

我刚刚修复了它，我忘记添加一个参数：

public String accountPage(@ModelAttribute("sessionBean") SessionBean sb);

你能填写你要传递给

accountPage（）

的值吗？另外，我不确定你所说的“键入的值”是什么意思。你是说你在表单中编辑的

人的属性没有更新吗？
@Entity
@Table (name="person")
public class Person implements Serializable {
    private static final long serialVersionUID = 3005461811554821039L;
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column (name="id")
    private int id;
    @Column (name="email")
    private String email;
    @Column (name="company")
    private String company;
    @Column (name="siret")
    private long siret;
    @Column (name="payment")
    private String payment;
    @Column (name="title")
    private String title;
    @Column (name="firstname")
    private String firstname;
    @Column (name="lastname")
    private String lastname;
    @Column (name="password", columnDefinition="char", length=64)
    private String password;
    @Column (name="phone")
    private String phone;
    @Column (name="fax")
    private String fax;
}

public String accountPage(@ModelAttribute("sessionBean") SessionBean sb);
