我需要编辑一个窗体，它处理两个实体类，file.java和client.java，它们的主键是client.clientId，位于file.java中。我可能在网址上做了一些错误，并且正在修复中。如何在Spring MVC中以单一形式编辑两个模型类
这是file.java
@Entity
public class file {
@Id
private int fileNumber;
private String fileName;
private String description;
private String purpose;
@Transient
private String assignedAdvocate;
private String comment;
private int Client_clientID;
@DateTimeFormat(pattern = "dd-MM-yyyy")
private Date timestamp;
这是client.java
@Entity
public class client {
@Id
@GeneratedValue
private int clientId;
@NotNull
private String clientName;
private String clientAddress;
private String contactPerson;
private int phone;
@Email
private String email;
private String bank;
private String branch;
private String accountNumber;
这是控制器类，其中我处理的编辑。
ManageFiles.java
@Controller
@RequestMapping("/advocatoree/manageFiles")
public class ManageFiles {
@PersistenceContext
EntityManager em;
@RequestMapping(value = "/searchFile")
public ModelAndView inputFileNumber(ModelAndView model){
model.setViewName("searchFile");
return model;
}
@Transactional
@RequestMapping(value = "/fileStatus", method = RequestMethod.GET)
public ModelAndView viewFileStatus(@RequestParam("file_number")int id, ModelAndView model){
model.setViewName("fileStatus");
file file = em.find(com.techflakes.advocatoree.model.file.class, id);
model.addObject("file", file);
client client = (com.techflakes.advocatoree.model.client)em.createQuery("SELECT c FROM client c WHERE c.clientId =:id")
.setParameter("id", file.getClient_clientID()).getSingleResult();
model.addObject("client", client);
List<deposit> deposits = (List<deposit>)em.createQuery("SELECT d FROM deposit d WHERE d.File_fileNumber =:id")
.setParameter("id", id).getResultList();
List<expense> expenses = (List)em.createQuery("SELECT e FROM expense e WHERE e.File_fileNumber =:id")
.setParameter("id", id).getResultList();
model.addObject("depositList", deposits);
model.addObject("expenseList", expenses);
List<bill> fileBills = em.createQuery("SELECT b FROM bill b WHERE b.file_fileNumber =:id")
.setParameter("id", id).getResultList();
model.addObject("fileBills", fileBills);
List<fileStatus> fileStatusList = (List)em.createQuery("SELECT f FROM fileStatus f WHERE f.file_fileNumber =:id").setParameter("id", id).getResultList();
for(fileStatus fs: fileStatusList){
String s =(String)em.createQuery("SELECT e.name FROM employee e WHERE e.employeeID =:id")
.setParameter("id", fs.getEmployee_employeeID()).getSingleResult();
fs.setEmployeeName(s);
}
model.addObject("fileStatusList", fileStatusList);
List<employee> employeeList = em.createQuery("SELECT e FROM employee e WHERE e.employeeID !=0").getResultList();
model.addObject("employeeList", employeeList);
List<Integer> employeefiles = em.createQuery("SELECT e.employee_employeeID FROM employeefile e WHERE e.file_fileNumber =:id")
.setParameter("id", id).getResultList();
ArrayList<String> employeeNames = new ArrayList<String>();
for(Integer i: employeefiles){
employee e = em.find(employee.class, i);
employeeNames.add(e.getName());
}
model.addObject("employeeNames", employeeNames.toString());
model.addObject("employeeFiles", employeefiles);
return model;
}
@Transactional
@RequestMapping(value = "/updateFileClient/{id}", method = RequestMethod.POST)
public ModelAndView modifyFileClientInfo(ModelAndView model, @PathVariable("id")int id){
model.setViewName("modifyFileClientInfo");
file file = em.find(com.techflakes.advocatoree.model.file.class, id);
// client client = em.find(com.techflakes.advocatoree.model.client.class, id);
client client = (com.techflakes.advocatoree.model.client)em.createQuery("SELECT c FROM client c WHERE c.clientId =:id")
.setParameter("id", file.getClient_clientID()).getSingleResult();
int zero=0;
List<employee> employeeList = em.createQuery("SELECT e FROM employee e WHERE e.employeeID >:zero")
.setParameter("zero", zero).getResultList();
model.addObject("employeeList", employeeList);
model.addObject("files", file);
model.addObject("clients", client);
return model;
}
@Transactional
@RequestMapping(value = "/updatedFileInfo/{id}", method = RequestMethod.POST)
public String updateFileInfo(@ModelAttribute("")file f, client c,
@PathVariable("id")int id){
file file = em.find(com.techflakes.advocatoree.model.file.class, id);
client client = em.find(com.techflakes.advocatoree.model.client.class, id);
// client client = (com.techflakes.advocatoree.model.client)em.createQuery("SELECT c FROM client c WHERE c.clientId =:id")
// .setParameter("id", file.getClient_clientID()).getSingleResult();
file.setFileName(f.getFileName());
file.setDescription(f.getDescription());
file.setPurpose(f.getPurpose());
file.setAssignedAdvocate(f.getAssignedAdvocate());
file.setComment(f.getComment());
file.setTimestamp(f.getTimestamp());
file.setClient_ClientID(c.getClientId());
client.setClientName(c.getClientName());
client.setClientAddress(c.getClientAddress());
client.setContactPerson(c.getContactPerson());
client.setPhone(c.getPhone());
client.setEmail(c.getEmail());
client.setBank(c.getBank());
client.setBranch(c.getBranch());
client.setAccountNumber(c.getAccountNumber());
em.persist(client);
em.flush();
em.refresh(client);
em.persist(file);
return "redirect:/advocatoree/manageFiles/searchFile";
}
}
这是filestatus.jsp
<form action="/advocatoree/manageFiles/updateFileClient/${file.fileNumber}" method="post">
<button type="submit" class="btn btn-purple">Edit Information</button>
</form>
编辑按钮，这是modifyFileClientInfo.jsp
<form method="post" action="/advocatoree/manageFiles/updatedFileInfo/${clients.clientId}">
URL操作一次，我编辑的数据，并提交他们，他们应该被保存在数据库中，并且还应该在我的页面中显示编辑后的信息。我看到的是当我单击编辑按钮时，它取得fileNumber，并且在我编辑并提交数据后，编辑后的信息将保存在与前一个文件的clientId相同的文件编号中。如果15是文件编号65的clientId，则数据将保留在文件编号15中。
请。帮帮我！
