spring を使用して UI で日付の問題が発生しました。データベースからクエリを取得すると、データ形式が UI に表示さ1987-02-12 00:00:00.0れます。値を送信すると、null がデータベースに入ります。私は使用しました
return getJdbcTemplate().update(
QUERY_CREATE_PROJECT,
new Object[] { employeeProject.getEmployeeNumber(),
employeeProject.getProjectCode(),
employeeProject.getStartDate(),
employeeProject.getEndDate(),
employeeProject.getProjectRole() }) != 0 ? true : false;
}春の方法、私の要件は、日付を形式（dd / MM / yyyy）で表示し、同じ形式で日付を挿入することです。カスタム日付で日付の形式を変換する方法plzは私を助け、カスタマイズの使用場所を教えてくれます日付、コントローラー層、DAO層、またはサービス層で日付をカスタマイズする必要があります
私のコントローラーの作成方法は
package com.nousinfo.tutorial.controllers;
import java.util.Map;
import javax.validation.Valid;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import com.nousinfo.tutorial.model.ProjectForm;
import com.nousinfo.tutorial.service.impl.ProjectServiceImpl;
import com.nousinfo.tutorial.service.model.EmployeeProjectBO;
/**
*
* @author ankurj
*
*/
@Controller
@RequestMapping("projectController")
public class ProjectController {
private ProjectServiceImpl projectServiceImpl;
public ProjectServiceImpl getProjectServiceImpl() {
return projectServiceImpl;
}
public void setProjectServiceImpl(ProjectServiceImpl projectServiceImpl) {
this.projectServiceImpl = projectServiceImpl;
}
/**
* Used to set the view
* @param id
* @return
* @throws Exception
*/
@RequestMapping(value = "/projectForm", method = RequestMethod.GET)
public ModelAndView view(@RequestParam("id") int id) throws Exception {
ModelAndView modelAndView = new ModelAndView();
System.out.println(id);
ProjectForm projectForm = new ProjectForm();
projectForm.setEmployeeNumber(id);
modelAndView.addObject("projectForm", projectForm);
modelAndView.setViewName("projectForm");
return modelAndView;
}
/**
* Create the project for an employee
* @param projectForm
* @param bindingResult
* @param model
* @return
* @throws Exception
*/
@RequestMapping(value = "/createProject", method = RequestMethod.POST)
public String createEmployee(@Valid ProjectForm projectForm,
BindingResult bindingResult, Map<String, ProjectForm> model)
throws Exception {
String form = null;
if (bindingResult.hasErrors()) {
return "projectForm";
}
model.put("projectForm", projectForm);
projectForm.setUpdateStatus("A");
if (projectForm.getUpdateStatus().charAt(0) == 'A') {
boolean flag = projectServiceImpl
.actionDecider(convertprojectFormToprojectBO(projectForm));
if (flag == false)
form = "DBError";
else
form = "Success";
}
return form;
}
/**
* This method update the existing detail of project
* @param projectForm
* @param bindingResult
* @return
*/
@RequestMapping(value = "/updateProject", method = RequestMethod.POST)
public String updateDepartment(
@ModelAttribute("projectForm") ProjectForm projectForm,
BindingResult bindingResult) {
String form = null;
projectForm.setUpdateStatus("M");
if (projectForm.getUpdateStatus().charAt(0) == 'M') {
boolean flag = projectServiceImpl
.actionDecider(convertprojectFormToprojectBO(projectForm));
if (flag == false)
form = "DBError";
else
form = "Success";
}
return form;
}
これが私のモデルクラスです
package com.nousinfo.tutorial.model;
import java.util.Date;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import org.hibernate.validator.constraints.NotEmpty;
import org.springframework.format.annotation.NumberFormat;
public class ProjectForm {
@NotNull
@NumberFormat
@Min(1)
private Integer employeeNumber;
@NotEmpty(message = "project code can't be blank")
private String projectCode;
private Date startDate;
private Date endDate;
private String role;
private String updateStatus;
public String getProjectCode() {
return projectCode;
}
public void setProjectCode(String projectCode) {
this.projectCode = projectCode;
}
public Date getStartDate() {
return startDate;
}
public void setStartDate(Date startDate) {
this.startDate = startDate;
}
public Date getEndDate() {
return endDate;
}
public void setEndDate(Date endDate) {
this.endDate = endDate;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public Integer getEmployeeNumber() {
return employeeNumber;
}
public void setEmployeeNumber(Integer employeeNumber) {
this.employeeNumber = employeeNumber;
}
public String getUpdateStatus() {
return updateStatus;
}
public void setUpdateStatus(String updateStatus) {
this.updateStatus = updateStatus;
}
}
これは私の日付用のjspです
