如何在另一個模型中設置模型屬性的形式：路徑

我可以爲一個模型設置一個單獨的路徑名，但是如果我嘗試爲另一個模型內的模型設置路徑，則會引發錯誤。我堅持這種友好給我一個解決方案，如果你詳細說明我要去哪裏工作，並且最好的地方在哪裏瞭解更多，這將是非常慷慨的。如何在另一個模型中設置模型屬性的形式：路徑

我想和大家分享我的代碼把它解決

THIS IS MY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"; 

}

這都是我的模型

我有兩個型號involed

聯繫方式是代碼

@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; 
}

}

是地址模式，下面是它

@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")

@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; 
}

}

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

是你的問題。我相信你會在上面的列表中只存儲兩種地址，我建議你綁定永久和通訊地址詳細信息作爲單獨的屬性，而不是綁定爲列表。

一些東西像ContactDetails豆@Transient private AddressDetails commAddressDetails和@Transient private AddressDetails permAddressDetails創建兩個以上Transient屬性和對應的setter /吸氣。

在你的Jsp中使用這些屬性的各個字段之前，堅持寫自己的邏輯來構造one-to-many的關係。如果你有靜態的地址數量，這將工作。

我很感謝你幫助我的時間，謝謝你。我的其他模型也以相同的方式開發，例如。我有employeeExp模型，其中包含我有公司名稱的pastExp屬性。所以用戶試圖從employee exp設置的名字應該放在pastExp的公司名稱中。爲此在employeeExp的jsp中，我給出了一個公司名稱爲pastExp.companyName的路徑。在這種情況下，我需要這樣做，但我得到了上面顯示的相同錯誤。如何解決這個問題。 –

在這種情況下，您的視圖設計如何？ - 這個答案可能對你有幫助。 http://stackoverflow.com/questions/33015654/how-to-bind-data-to-list-in-spring-form/33148339#33148339 – Lovababu

謝謝-Lovababu。我認爲那就是我想要做的。我需要在模型中綁定我的模型。爲此，我用pastExp.companyName作爲路徑。但我得到了同樣的錯誤 –
