这期内容当中小编将会给大家带来有关这么早JAVA中利用SSM框架搭建一个CRUD，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

使用的是Maven插件来配置我们需要的jar包，由于操作不多，所以并没有配置很多，要注意自己使用的jdk的版本，选择不同版本号的jdk

然后配置数据库的连接，改成自己的数据库就行了

driver=com.mysql.jdbc.Driver
url=jdbc\:mysql\://locahost\:3306/db
username=root
password=root
maxActive=20
maxIdle=20
minIdle=1
maxWait=60000

配置文件spring-dao.xml，Spring会自动查找其下的类

<?xml version="1.0" encoding="UTF-8"?>

    <property name="sqlSessionFactory" ref="sqlSessionFactory"></property> 
  </bean>

配置文件Spring和Mybatis的整合文件

配置事物的文件

好了！！！需要配置的文件已经配置完成了，足够我们进行一波操作了

接下来是后台的一些代码，这里主要是实体类，dao层，service层，controller层，我把后台的文件一起上传了，mapper.xml文件是实现方法最关键的地方
