如何为另一个模型中的模型属性设置 form:path

Question

我可以为一个模型设置一个单独的路径名，但是如果我试图为另一个模型中的一个模型设置一个路径，它会抛出一个错误。我坚持这个请给我一个解决方案，如果你详细说明并解释我要穿什么以及最好的地方在哪里了解更多，那将是非常慷慨的。

我想分享我的代码来解决它

这是我的控制器

@RequestMapping(value="contact", method=RequestMethod.GET)
public String contactability(HttpServletRequest request, HttpServletResponse response, Model model, @ModelAttribute("contactDetails") ContactDetails contactDetails){
    try{
        if(contactDetails==null){
            contactDetails= new ContactDetails();
        }
        model.addAttribute("contactabality", contactDetails);

    }catch(Exception e){
        e.printStackTrace();
    }

    return "contactabality";

}

这是我的模型

我有两个模型参与

这里是联系方式代码

@Entity
@Table(name="TB_CONTACT_DETAILS")
public class ContactDetails implements Serializable {

@Id
@GeneratedValue
@Column(name="CONTACT_ID")
private Long contactId;

@Column(name="IS_PERM_COMM_SAME")
private Integer isPermCommSame;

@OneToMany(fetch=FetchType.EAGER,cascade=CascadeType.ALL, mappedBy="contactDetails")
private Set<AddressDetails> addressDetails = new HashSet<AddressDetails>();

public ContactDetails() {
    // TODO Auto-generated constructor stub
}

public Long getContactId() {
    return contactId;
}

public void setContactId(Long contactId) {
    this.contactId = contactId;
}

public Integer getIsPermCommSame() {
    return isPermCommSame;
}

public void setIsPermCommSame(Integer isPermCommSame) {
    this.isPermCommSame = isPermCommSame;
}

public Set<AddressDetails> getAddressDetails() {
    return addressDetails;
}

public void setAddressDetails(Set<AddressDetails> addressDetails) {
    this.addressDetails = addressDetails;
}

}

是地址模型，下面是它的代码

@Entity
@Table(name="TB_ADDRESS_DETAILS")
public class AddressDetails implements Serializable{

@Id
@GeneratedValue
@Column(name="ADDRESS_ID")
private Long addrId;

@ManyToOne(fetch=FetchType.EAGER, cascade=CascadeType.DETACH)
@JoinColumn(name="ADDR_TYPE")
private AddressTypeMaster addressType;

@Column(name="ADDRESS_COL1")
private String addrCol1;

@Column(name="ADDRESS_COL2")
private String addrCol2;

@Column(name="ADDRESS_COL3")
private String addrCol3;

@ManyToOne(fetch=FetchType.EAGER,cascade=CascadeType.DETACH)
@JoinColumn(name="CITY")
private CityMaster city;

@Column(name="PINCODE")
private String pincode;

@ManyToOne(fetch=FetchType.EAGER,cascade=CascadeType.DETACH)
@JoinColumn(name="STATE")
private StateMaster state ;

@ManyToOne(fetch=FetchType.EAGER,cascade=CascadeType.ALL)
@JoinColumn(name="CONTACT_ID")
private ContactDetails contactDetails;

@Column(name="ADDR_STATUS")
private String addrStatus;

@OneToOne(fetch=FetchType.EAGER,cascade=CascadeType.ALL,mappedBy="addressDetails")
private EmployeeDetails employeeDetails;

public AddressDetails() {
    // TODO Auto-generated constructor stub
}

public Long getAddrId() {
    return addrId;
}

public void setAddrId(Long addrId) {
    this.addrId = addrId;
}

public AddressTypeMaster getAddressType() {
    return addressType;
}

public void setAddressType(AddressTypeMaster addressType) {
    this.addressType = addressType;
}


public String getAddrCol1() {
    return addrCol1;
}

public void setAddrCol1(String addrCol1) {
    this.addrCol1 = addrCol1;
}

public String getAddrCol2() {
    return addrCol2;
}

public void setAddrCol2(String addrCol2) {
    this.addrCol2 = addrCol2;
}

public String getAddrCol3() {
    return addrCol3;
}

public void setAddrCol3(String addrCol3) {
    this.addrCol3 = addrCol3;
}

public CityMaster getCity() {
    return city;
}

public void setCity(CityMaster city) {
    this.city = city;
}

public String getPincode() {
    return pincode;
}

public void setPincode(String pincode) {
    this.pincode = pincode;
}

public StateMaster getState() {
    return state;
}

public void setState(StateMaster state) {
    this.state = state;
}

public ContactDetails getContactDetails() {
    return contactDetails;
}

public void setContactDetails(ContactDetails contactDetails) {
    this.contactDetails = contactDetails;
}

public String getAddrStatus() {
    return addrStatus;
}

public void setAddrStatus(String addrStatus) {
    this.addrStatus = addrStatus;
}

public EmployeeDetails getEmployeeDetails() {
    return employeeDetails;
}

public void setEmployeeDetails(EmployeeDetails employeeDetails) {
    this.employeeDetails = employeeDetails;
}

}

请帮我解决这个问题。谢谢

Answer 1

private Set<AddressDetails> addressDetails = new HashSet<AddressDetails>();

是你的问题。我相信您只会在上面的列表中存储两种地址，我建议您将 Permanent 和 Communication 地址详细信息单独绑定属性而不是绑定为列表。

比如在 ContactDetails bean @Transient private AddressDetails commAddressDetails 和 @Transient private AddressDetails permAddressDetails 中创建另外两个 Transient 属性以及相应的 setter/getter.

在您的 Jsp 中为各个字段使用这些属性，然后再坚持编写您自己的逻辑来构建 one-to-many 关系。如果您有静态数量的地址，这将起作用。
