spring封装对象中有时间格式 出现400错误

spring封装对象，如果对象中有时间格式，会出现400错误。

解决方法Controller中第一个方法添加自定义类型转换器

@Controller
@RequestMapping("/log")
public class LogController {
	
	LogService logService = new LogService();
	
	//自定义类型转换器
	@InitBinder
	public void initBinder(HttpServletRequest request,ServletRequestDataBinder binder) throws Exception {
		binder.registerCustomEditor(
				Date.class, 
				new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"),true));
	}
	
	@RequestMapping("/getManageLog")
	public ModelAndView getManageLog(ManageLogObj manageLogObj,HttpServletRequest request) throws Exception {
		
		ModelAndView mv = new ModelAndView("/log/manage_log");
		List<ManageLogObj> manageLogObj_list = logService.getManageLog(manageLogObj);
		mv.addObject("manageLogObj_list",manageLogObj_list);
		return mv;
	}
}
