ssm框架搭建（Spring+spring mvc+ mybatis）
这几天一直想自己搭建一个ssm框架（使用的是eclipse)，因为没有自己搭建过，所以真心废了好大劲儿，今天与大家分享下，也记录下，方便以后可以看看（如果各位大拿有任何好的建议，欢迎批评）。中间参考微博链接
其实整体结构我相信大家都会写，最主要的就是配置文件的那部分和jar包（我会放到网盘，供大家下载，还是比较全的）

jdbc.properties：
#jdbc config
jdbc.driver = com.mysql.jdbc.Driver
#jdbc.url = jdbc:mysql://localhost:3306/mybatis
jdbc.url = jdbc\:mysql\://localhost\:3306/yxx?useUnicode\=true&characterEncoding\=gbk
jdbc.username = root
jdbc.password = 960530

这些主要是配置文件，其他的Java文件内容太多，就不上传了。这也是我第一次，多多包涵
