Question

我在我的应用程序中使用jQuery datepicker作为文本字段。我能够以（dd-MM-yy）格式正确插入数据。但问题是将日期以不同的格式（带有时区的日期和时间）返回到验证哪个文本字段会导致异常。

Student.java

public class Student {
	private final static Logger logger=Logger.getLogger(Student.class);
private Integer sid;

private String firstName;

private String middleName;

private String lastName;

private String fatherName;

private String motherName;

private Date dateOfBirth;

private Integer admissionNo;

private Date dateOfJoining;

private String standard;

private String section;

private String medium;

private Address address;

StudentController.java

    @Controller
    @RequestMapping("/student")
    public class StudentController {
    	
    	private final static Logger logger=Logger.getLogger(StudentController.class);
    	
    	@Autowired
    	private StudentService studentService;
    	
    	@Autowired
    	private StudentValidator studentValidator;
    	
    	@RequestMapping("/form")
    	public ModelAndView getForm(@ModelAttribute Student student,Model model){
    		initModelList(model);
    		
    		logger.info("This  is a message");
    	return new ModelAndView("form");
    	}
    	
    	@RequestMapping("/register")
    	public String addStudent(@ModelAttribute("student") Student student, Model model, BindingResult bindingResult,SessionStatus status){
    		
    		studentService.addStudent(student);
    		initModelList(model);
    		studentValidator.validate(student, bindingResult);
    		if(bindingResult.hasErrors()){
    			return "form";
    		}else{
    		logger.info("Student added successfully...");
    		status.setComplete();
    		return "redirect:list";
    		}
    	}
    	
    	@InitBinder
    	protected void initBinder(WebDataBinder binder) {
    	    SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yy");
    	    dateFormat.setLenient(true);

请解决我的问题，提前致谢..

Answer 1

我认为您必须在控制器中添加以下initbinder，它将转换为所需的格式。

@InitBinder
public void initBinder(WebDataBinder binder) {
    CustomDateEditor editor = new CustomDateEditor(new SimpleDateFormat("dd-MMMM-yy"), true);
    binder.registerCustomEditor(Date.class, editor);
}

还在Student class中使用日期字段的注释。

@DateTimeFormat(pattern = "dd-MMMM-yy")
private Date dateOfBirth;

@DateTimeFormat(pattern = "dd-MMMM-yy")
private Date dateOfJoining;

Answer 2

@DateTimeFormat(pattern = "dd-MMMM-yy")
private Date dateOfBirth;

@DateTimeFormat(pattern = "dd-MMMM-yy")
private Date dateOfJoining;

这些线解决了我的问题......谢谢Mr. RE350

在Spring MVC中从日期验证时获取不同格式的日期
