这是我的同意模式
@Entity
@Table(name = "consents")
public class Consent extends BaseEntity {
/**
*/
@OneToOne
@JoinColumn(name = "provider_id")
private Provider provider;
@OneToOne
@JoinColumn(name = "user_id")
private User user;
@OneToOne
@JoinColumn(name = "friend_id")
private User friend;
@OneToOne
@JoinColumn(name = "document_id")
private Document document;
@Column(name = "status")
private String status;
/**
* C
* @return
*/
public void Provider() {
}
public Provider getProvider() {
return this.provider;
}
/**
*
* Setter for property pet.
*
* @param pet New value of property pet.
*
*/
public void setProvider(Provider provider) {
this.provider = provider;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public User getFriend() {
return friend;
}
public void setFriend(User friend) {
this.friend = friend;
}
public Document getDocument() {
return document;
}
public void setDocument(Document document) {
this.document = document;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}
这是同意控制器获取声明
@RequestMapping(value = "/users/{userId}/providers/{providerId}/documents/{documentId}/consents/new", method = RequestMethod.GET)
public String initNewConsentForm(@PathVariable("userId") int userId,@PathVariable("providerId") int providerId,@PathVariable("documentId") int documentId, Model model) {
User user = this.clinicService.findUserById(userId);
Provider provider = this.clinicService.findProviderById(providerId);
Document document = this.clinicService.findDocumentById(documentId);
Collection<User> users = this.clinicService.AllUsers();
Consent consent = new Consent();
//document.addConsent(consent);
//provider.addDocument(document);
//user.addProvider(provider);
model.addAttribute("provider",provider);
model.addAttribute("document", document);
model.addAttribute("user", user);
model.addAttribute("users", users);
model.addAttribute("consent", consent);
return "providers/createOrUpdateConsentForm";
}
这是声明后的同意
@RequestMapping(value = "/users/{userId}/providers/{providerId}/documents/{documentId}/consents/new", method = RequestMethod.POST)
public String processNewConsentForm(@PathVariable("userId") int userId, @PathVariable("providerId") int providerId,
@PathVariable("documentId") int documentId, @ModelAttribute("consent") Consent consent, BindingResult result, SessionStatus status) {
User user = this.clinicService.findUserById(userId);
Provider provider = this.clinicService.findProviderById(providerId);
//System.out.println("daghade");
//System.out.println(provider);
//Document doc = this.clinicService.findDocumentById(userId);
Consent c =new Consent();
c.setProvider(consent.getProvider());
c.setDocument(consent.getDocument());
c.setUser(user);
c.setStatus(consent.getStatus());
c.setFriend(consent.getFriend());
System.out.print("consentcontroller11");
System.out.println(consent.getProvider());
System.out.print("consentcontroller11");
if (result.hasErrors()) {
return "providers/createOrUpdateConsentForm";
} else {
this.clinicService.saveConsent(c);
status.setComplete();
return "redirect:/users/{userId}";
}
}
同意html百日咳形式

错误消息告知user模型属性为null
在您的帖子请求映射中添加模型属性，如下所示
@RequestMapping(value = "/users/{userId}/providers/{providerId}/documents/{documentId}/consents/new", method = RequestMethod.POST)
public String processNewConsentForm(Model model, @PathVariable("userId") int userId, @PathVariable("providerId") int providerId,
@PathVariable("documentId") int documentId, @ModelAttribute("consent") Consent consent, BindingResult result, SessionStatus status) {
...
if (result.hasErrors()) {
User user = this.clinicService.findUserById(userId);
Provider provider = this.clinicService.findProviderById(providerId);
Document document = this.clinicService.findDocumentById(documentId);
Collection<User> users = this.clinicService.AllUsers();
model.addAttribute("provider",provider);
model.addAttribute("document", document);
model.addAttribute("user", user);
model.addAttribute("users", users);
model.addAttribute("consent", consent);
return "providers/createOrUpdateConsentForm";
}
...
