ssm框架的简单案例

学完ssm框架后做了一个简单的案例，实现简单的增删改查。

项目结构图：

看项目结构：

关键代码：

前端是jsp技术，当然也可以用vue分离的自己选择就好。

订单页面：

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@page isELIgnored="false" %>
<%@include file="./common/head.jsp"%>


       

           你现在所在的位置是:
           订单管理页面
       
       

       

			
			商品名称：
			
			 
			供应商：
			
				
				   --请选择--
				   
				   		${provider}
				   
				
       		
			 
			是否付款：
			
				--请选择--
				queryIsPayment == 1 ? "selected="selected"":"" }>未付款
				queryIsPayment == 2 ? "selected="selected"":"" }>已付款

       		
			
			 
			 添加订单
		
       


       
      
				

          

              
订单编码

是否付款

					${bill.billCode }
					
					

					${bill.productName }
					
					

					${bill.providerId}
					
					

					${bill.totalPrice}
					
					

					
						未付款
						已付款
					
					
					

					
					${bill.creationDate}
					
					
					

					bill.id } billcc=${bill.billCode }>


					bill.id } billcc=${bill.billCode }>


					bill.id } billcc=${bill.billCode }>


					
				
			
      
  





    

        提示
        

            
你确定要删除该订单吗？
            确定
            取消
        
    


<%@include file="./common/foot.jsp" %>

界面就没有上面好看的了，框架自行下载。

供应商页面：

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@page isELIgnored="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@include file="./common/head.jsp"%>


        

            你现在所在的位置是:
            供应商管理页面
        
        

        	

				
				供应商编码：
				
				
				供应商名称：
				
				
				
				添加供应商

主要是前后端的交互部分，控制器都是由spring容器控制，注意要释放静态资源。

订单后台：
