SSM框架整合（Spring + SpringMVC + MyBatis）

搭建环境

使用Spring（业务层）整合其他的框架SpringMVC（表现层）和MyBatis（持久层）

Spring框架

1. 创建数据库表

   CREATE DATABASE ssm;
   USE ssm;
   CREATE TABLE account(
   	id INT PRIMARY KEY AUTO_INCREMENT,
   	NAME VARCHAR(20),
   	money DOUBLE
   );
   

2. pom文件导入坐标

     <properties>
       <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
       <maven.compiler.source>1.8</maven.compiler.source>
       <maven.compiler.target>1.8</maven.compiler.target>
       <spring.version>5.0.2.RELEASE</spring.version>
       <slf4j.version>1.6.6</slf4j.version>
       <log4j.version>1.2.12</log4j.version>
       <mysql.version>5.1.6</mysql.version>
       <mybatis.version>3.4.5</mybatis.version>
     </properties>
