如何在另一个模型中设置模型属性的形式：路径

分类: 技术问答 • 2022-06-07 23:08:52
问题描述：

我可以为一个模型设置一个单独的路径名，但是如果我尝试为另一个模型内的模型设置路径，则会引发错误。我坚持这种友好给我一个解决方案，如果你详细说明我要去哪里工作，并且最好的地方在哪里了解更多，这将是非常慷慨的。如何在另一个模型中设置模型属性的形式：路径

我想和大家分享我的代码把它解决

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"; 

}

这都是我的模型

我有两个型号involed

  1. 联系方式是代码

    @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; 
}

    }

  2. 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") 
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; 
}

    }

请帮我弄清楚这一点。 谢谢

答 

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

是你的问题。我相信你会在上面的列表中只存储两种地址，我建议你绑定永久和通讯地址详细信息作为单独的属性，而不是绑定为列表。

一些东西像ContactDetails豆@Transient private AddressDetails commAddressDetails和@Transient private AddressDetails permAddressDetails创建两个以上Transient属性和对应的setter /吸气。

在你的Jsp中使用这些属性的各个字段之前，坚持写自己的逻辑来构造one-to-many的关系。如果你有静态的地址数量，这将工作。

我很感谢你帮助我的时间，谢谢你。我的其他模型也以相同的方式开发，例如。我有employeeExp模型，其中包含我有公司名称的pastExp属性。所以用户试图从employee exp设置的名字应该放在pastExp的公司名称中。为此在employeeExp的jsp中，我给出了一个公司名称为pastExp.companyName的路径。在这种情况下，我需要这样做，但我得到了上面显示的相同错误。如何解决这个问题。 –

在这种情况下，您的视图设计如何？ - 这个答案可能对你有帮助。 http://stackoverflow.com/questions/33015654/how-to-bind-data-to-list-in-spring-form/33148339#33148339 – Lovababu

谢谢-Lovababu。我认为那就是我想要做的。我需要在模型中绑定我的模型。为此，我用pastExp.companyName作为路径。但我得到了同样的错误 –
