从零搭建SSM（spring springMVC mybatis） 后台框架
闲来无事复习了一下SSM搭建，给刚入坑的小白提供一个空白框架学习，话不多说 上代码 代码中有详细注解 介绍
一、创建SSM框架需要的配置文件 applicationContext.xml spring-mvc.xml spring-server.xml
applicationContext.xml 用于spring 集成 mybatis等
classpath:config.properties
spring-mvc.xml
text/html;charset=UTF-8
application/json
WriteMapNullValue
QuoteFieldNames
spring-server.xml
config.properties 数据库连接

搭建过程很顺利 看完了不难吧 看完的小伙伴 希望能帮助你们
