使用ssm+maven+bootstrap+mysql实现增删改查的一个小demo

目录

一.运行效果

二，新建mavenProject

三，详细代码

web.xml

springmvc.xml

db.properties

applicationContext_mapper.xml

applicationContext_service.xml

applicationContext_transaction.xml

ItemInfo.java

ItemController.java

ItemMapper.java

ItemMapper.xml

ItemService.java

ItemServicelmpl.java

item_list.jsp

四，运行。右键项目-【run as】-【maven build...】

五，MySQL数据库文件

六，完整项目下载

此项目和这个项目都能实现同样的功能，但是这个项目是maven project，那个项目是dynamic web project

这里需要maven的基础：https://blog.csdn.net/qq_40323256/article/details/90168191

ssm的基础：https://blog.csdn.net/qq_40323256/article/details/89791744

bootstrap的基础：https://blog.csdn.net/qq_40323256/article/details/91490905

MySQL的基础：https://blog.csdn.net/qq_40323256/article/details/82905734

一.运行效果

先来看一下最终运行效果

 

二，新建mavenProject

注意：

1，选择war包。

2，通常新建的maven项目会报错，这是因为没有web.xml，解决此报错很简单，直接在项目上右键【Java EE Tools】-【generate deployment xxx】，然后就不报错了

先看下目录

三，详细代码

用maven的好处之一就是不用到处找jar包，想要什么jar包直接在pom.xml里面添加依赖就可以了。想要依赖可以去中央仓库找

我们可以把常用的依赖收集起来，以后可以直接复制pom.xml，省时省力

pom.xml

四，运行。右键项目-【run as】-【maven build...】

右键项目-【run as】-【maven build...】，在Goals中输入：clean tomcat7:run，如果不能运行，就用：tomcat7:run

第一次运行maven项目时输入clean tomcat7:run，后面就用  clean tomcat7:redeploy 

五，MySQL数据库文件
