RegisterServlet的实现

主要是表单提交的日期是String类型，User需要的类型是Date类型

ConvertUtils.register注册转换器

/**
 * Servlet implementation class RegisterServlet
 */
@WebServlet("/RegisterServlet")
public class RegisterServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
	 /**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		IUserService userService=new UserServiceImpl();
		User user=new User();
		try {
			ConvertUtils.register(new DateLocaleConverter(), Date.class);
			
			BeanUtils.populate(user, request.getParameterMap());
			System.out.println("请求参数"+user);
			userService.register(user);
			
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}		
	}
}

添加注册成功后的中文提示和跳转主页，还有注册失败后的提示

	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		response.setContentType("text/html;charset=utf-8");
		IUserService userService=new UserServiceImpl();
		User user=new User();
		try {
			ConvertUtils.register(new DateLocaleConverter(), Date.class);
			
			BeanUtils.populate(user, request.getParameterMap());
			System.out.println("请求参数"+user);
			userService.register(user);
			response.getWriter().write("注册成功,3秒后转回主页");
			response.setHeader("refresh", "3;url="+request.getContextPath()+"/index.jsp");
			
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			response.getWriter().write("注册失败，"+e.getMessage());
		}		
	}
