这几天粗浅的把shiro整合到spring中，并且注解控制shiro用户/角色/权限And/OR

步骤：

1.首先maven搭建web项目

2.创建数据库 user/role/authority 其中，role->user是一对多，role->authority是多对多

shiros.sql内容：

其中：1>shiro需要开启注解

　　　2>shiro自定义异常处理【这个自定义的异常处理类需要自己写】

　　   3>/=anon表示跟路径【http://localhost:8080/shiro-first/】是不拦截的

　　　4>/index.jsp=anon表示【http://localhost:8080/shiro-first/index.jsp】是不拦截的

　　　5>/js/** = anon表示【http://localhost:8080/shiro-first/js/jquery.js】这种类型的资源请求都是不拦截的

　　　6>/**=authc 表示除了上面定义的不拦截之外的其他请求地址均需要被拦截到，被拦截到是需要验证 当前访问这个地址的 用户是否已经通过验证，也就是是否登录过，如果没有，会根据上面配置的<property name="loginUrl" value="/index.jsp"/>跳转指定页面，这里就是指定到登录页面。

　　　7><property name="unauthorizedUrl" value="/error.jsp"/>如果没有整合使用springMVC跳转页面，那么这个就是有用的，现在页面的跳转交给springMVC来控制，这个权限认证不通过的配置就不起作用了，而是springMVC根据抛出异常，然后根据自定义的异常处理类，跳转到指定的页面了。

　　　8>

  1. <!-- 自定义Realm

  3.            <property name="sessionFactory" ref="sessionFactory" />
  4.     </bean>-->

　　　自定义的这个Realm相当于咱们自己写的Filter，其中是实现了shiro提供的接口，进行了相对应的处理，拿到了本用户以及本用户所对应的权限，交给shiro自行比较，完成验证。

　　　9>/login/login.htmls=anon需要加后缀是因为web.xml中的相关配置未拦截到相关的请求页面，仅注意就好

11.项目搭建完成，启动tomcat

访问地址：http://localhost:8080/shiro-first/

用数据库中的某个用户登录：张三 123456

使用张三登录成功之后，张三的role是管理员1，管理员1对应的权限有疾病的增删改查，数据库中有

然后，此时张三登陆成功，

直接在地址栏修改地址为：http://localhost:8080/shiro-first/login/admin1.htmls

而更改地址为：http://localhost:8080/shiro-first/login/admin2.htmls

同理 测试其他的地址 即可！！！！！
