二、项目运行

环境配置: Jdk1.8 + Tomcat8.5 + Mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)

项目技术: JSP + Struts + Spring + Hibernate + html + css + JavaScript + JQuery等等。

用户登录拦截器代码:

@WebFilter(filterName="CheckLoginFilter",value="/back/*",[email protected](name="errorPage",value="index.html"))
public class CheckLoginFilter implements Filter{
	private String path = "index.html";
	@Override
	public void destroy() {
		
	}

	@Override
	public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain chain) throws IOException, ServletException {
		HttpServletRequest request = (HttpServletRequest) arg0;
		HttpServletResponse response = (HttpServletResponse) arg1;
		
		HttpSession session = request.getSession();
		if (session.getAttribute("currentLoginUser") == null) { // 说明用户没有登录
			response.setContentType("text/html;charset=utf-8");
			PrintWriter out = response.getWriter();
			String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort() + request.getContextPath() +"/";
			out.print("<script>alert('请先登录...');location.href='" + basePath + path + "';</script>");
			out.flush();
			out.close();
		} else { // 如果已经登录,则交给下一个过滤器过滤
			chain.doFilter(request, response);
		}
	}

	@Override
	public void init(FilterConfig arg0) throws ServletException {
		String tmp = arg0.getInitParameter("errorPage");
		if (tmp != null) {
			path = tmp;
		}
	}
}

订单信息控制层:

@Controller
@RequestMapping("/orderInfo")
public class OrderInfoController  {
	@Autowired
	private IOrderInfoBiz orderInfoBiz;
	
	@RequestMapping("/addOrderInfo")
	@ResponseBody
	public Integer addOrderInfo(String ono, String odate, String ano, String price) {
		Integer in = 0;
		try {
			in = orderInfoBiz.addOrderInfo(ono, odate,ano,price);
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return in;
	}
	
	@RequestMapping("/getOrder")
	@ResponseBody
	public List<OrderInfo> getOrder(String mno) {

		}catch(IllegalStateException e){

	}
	//管理员端的商品信息
	@RequestMapping("/addGood")
	@ResponseBody
