jsp +springboot+ springmvc + mybatis + thymeleaf + ftp+ javascript + jquery + ajax + maven等等

登录控制层：

@webservlet(name = "user_login",urlpatterns = "/user_login")
public class userloginservlet extends httpservlet {
    private userservice uservice = new userservice();
    protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
        string ue = request.getparameter("ue");
        string password = request.getparameter("password");
        user user = uservice.login(ue, password);
        if(user==null) {
            request.setattribute("failmsg", "用户名、邮箱或者密码错误，请重新登录！");
            request.getrequestdispatcher("/user_login.jsp").forward(request, response);
        }else {
            request.getsession().setattribute("user", user);
            request.getrequestdispatcher("/user_center.jsp").forward(request, response);
        }
    }
 
    protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
 
    }
}

商品信息列表：

@webservlet(name = "goods_list",urlpatterns = "/goods_list")
public class goodslistservlet extends httpservlet {
    private goodsservice gservice=new goodsservice();
    private typeservice tservice=new typeservice();
    protected void dopost(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
 
    }
 
    protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
        int id=0;
        if(request.getparameter("typeid")!=null)
        {
            id=integer.parseint(request.getparameter("typeid"));
        }
        int pagenumber=1;
        if(request.getparameter("pagenumber")!=null) {
            try {
                pagenumber=integer.parseint(request.getparameter("pagenumber"));
            }
            catch (exception e)
            {
 
            }
 
        }
        type t=null;
        if(id!=0)
        {
            t=tservice.selecttypenamebyid(id);
        }
        request.setattribute("t",t);
        //list<goods> list=gservice.selectgoodsbytypeid(id,1,8);
        //request.setattribute("goodslist",list);
        if(pagenumber<=0)
            pagenumber=1;
        page p=gservice.selectpagebytypeid(id,pagenumber);
 
        if(p.gettotalpage()==0)
        {
            p.settotalpage(1);
            p.setpagenumber(1);
        }
        else {
            if(pagenumber>=p.gettotalpage()+1)
            {
                p=gservice.selectpagebytypeid(id,p.gettotalpage());
            }
        }
 
        request.setattribute("p",p);
        request.setattribute("id",string.valueof(id));
        request.getrequestdispatcher("/goods_list.jsp").forward(request,response);
    }
}

管理员订单服务类：

@webservlet(name = "admin_order_list",urlpatterns = "/admin/order_list")
public class adminorderlistservlet extends httpservlet {
    private orderservice oservice = new orderservice();
    /**
     * @see httpservlet#doget(httpservletrequest request, httpservletresponse response)
     */
    protected void doget(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception {
        int status = 0;
        if(request.getparameter("status") != null) {
            status=integer.parseint(request.getparameter("status") ) ;
        }
        request.setattribute("status", status);
        int pagenumber = 1;
        if(request.getparameter("pagenumber") != null) {
            try {
                pagenumber=integer.parseint(request.getparameter("pagenumber") ) ;
            }
            catch (exception e)
            {
 
            }
        }
        if(pagenumber<=0)
            pagenumber=1;
        page p = oservice.getorderpage(status,pagenumber);
        if(p.gettotalpage()==0)
        {
            p.settotalpage(1);
            p.setpagenumber(1);
        }
        else {
            if(pagenumber>=p.gettotalpage()+1)
            {
                p = oservice.getorderpage(status,pagenumber);
            }
        }
 
        request.setattribute("p", p);
        request.getrequestdispatcher("/admin/order_list.jsp").forward(request, response);
    }
}
