springmvc自定义日期编辑器

1.控制器

@Controller
public class MyController {

    // 处理器方法
    @RequestMapping(value = "/first.do")
    public String doFirst(Date birthday, int age) {
        return "/jsp/two.jsp";
    }

    // 自定义一个方法
    @InitBinder
    public void initBinder(WebDataBinder binder) {
        DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        binder.registerCustomEditor(Date.class, new MyDateEdit());
    }
}

2.自定义日期编辑器

public class MyDateEdit extends PropertiesEditor {

    @Override
    public void setAsText(String source) throws IllegalArgumentException {
        SimpleDateFormat sdf = getDateFromte(source);
        try {
            Date date = sdf.parse(source);
            setValue(date);
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }

    private SimpleDateFormat getDateFromte(String source) {

        SimpleDateFormat sdf = new SimpleDateFormat();

        if (Pattern.matches("^\\d{4}-\\d{2}-\\d{2}$", source)) {
            sdf = new SimpleDateFormat("yyyy-MM-dd");
        }
        if (Pattern.matches("^\\d{4}/\\d{2}/\\d{2}$", source)) {
            sdf = new SimpleDateFormat("yyyy/MM/dd");
        }
        if (Pattern.matches("^\\d{4}\\d{2}\\d{2}$", source)) {
            sdf = new SimpleDateFormat("yyyyMMdd");
        }
        if (Pattern.matches("^\\d{4}年\\d{2}月\\d{2}日$", source)) {
            sdf = new SimpleDateFormat("yyyy年MM月dd日");
        }
        return sdf;
    }

}
