篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了JavaWeb之ssm框架整合，用户角色权限管理相关的知识，希望对你有一定的参考价值。
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。
项目结构：
代码（引用，未完全实现）：
配置文件：
