JavaWeb之ssm框架整合，用户角色权限管理

SSM框架整合

Spring

SpringMVC

MyBatis

导包:
1, spring
2, MyBatis
3, mybatis-spring
4, fastjson
5, aspectweaver----AspectJ框架
6, log4j-----打印日志信息
7, ojdbc6.jar
8, jstl.jar, standard.jar----标准标签库
9, commons-logging-1.2.jar

src下建立包结构

配置web.xml，spring-mvc.xml，spring-all.xml

建立表结构，使用PowerDesigner

前台页面，后台方法等。
