毕设系列之基于IDEA2019.01的SSM框架搭建

第一篇博客，记录一下这两个月来的毕设学习知识点,首先是SSM框架的环境搭建

前置条件：耐心100%；IDEA2019.01；JDK 1.8.0_221；Tomcat 8.5；MySQL5.7

新建一个web工程

初始界面

Maven导入搭建环境需要用到的包

替换pom.xml下标签和标签的内容

自定义类注释（可以跳过）

File>Settings>Editor>File and Code Templates>Includes

创建数据库表对应的实体类

创建持久层接口

account的增删查改

创建业务层接口

account的业务层接口方法

account业务层接口实现类

创建控制器

account的控制器

创建jsp文件

index.jsp编写一个简单的测试链接

<html>
<body>
<a href="account/findAll">测试查询所有</a>
</body>
</html>

创建list.jsp
由于springmvc.xml的视图解析器配置，list.jsp创建于WEB-INF的pages目录下，由springMVC控制跳转


list.jsp接收AccountController传过来的值

至此SSM框架的搭建就完成了，步骤有点繁琐，但后期用起来很爽。

想详细学习SSM的可以从MyBatis开始入手
