我在使用 spring 的 UI 中遇到日期问题，当我从数据库中获取查询时，我的 UI 中显示的数据格式是1987-02-12 00:00:00.0当我提交值 null 进入数据库时。我用过
return getJdbcTemplate().update(
QUERY_CREATE_PROJECT,
new Object[] { employeeProject.getEmployeeNumber(),
employeeProject.getProjectCode(),
employeeProject.getStartDate(),
employeeProject.getEndDate(),
employeeProject.getProjectRole() }) != 0 ? true : false;
}春天的方法，我的要求是以格式（dd / MM / yyyy）显示日期并以相同格式插入日期。如何在我们的自定义日期中转换日期格式请帮助我并告诉我在哪里使用自定义日期，我应该在控制器层、DAO 层还是在服务层自定义日期
我的控制器创建方法是
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;
}
这是我的模型课
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;
}
}
这是我约会的jsp
