Question

我在使用spring遇到UI中的日期问题，当我从数据库中获取查询时，我的UI中显示的数据格式为1987-02-12 00:00:00.0，当我提交值时，数据库中的值为null。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，我的重新测试是以格式显示日期（dd / MM / yyyy）并以相同的格式插入日期。如何在我们的自定义日期转换日期格式plz帮助我和还告诉我在哪里使用日期定制，我应该在控制器层，DAO层或服务层中自定义日期

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

         * @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;
    }

这是我的模型类

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;
    }

}

Answer 1

您只需要日期类型的自定义编辑器，您可以通过该编辑器格式化传入的＆amp;传出日期对象。这已在帖子中解释

Spring MVC - Binding a Date Field

使用spring自定义日期格式
