shiro+springmvc+mybatis【转】 / 憋错料

<span style="background-color: rgb(255, 255, 255); font-family: Arial, Helvetica, sans-serif;">
</span>

一直以来，从开发到现在，都还没自己研究过权限控制。问了老大，老大让我学习shiro。

<span style="background-color: rgb(255, 255, 255); font-family: Arial, Helvetica, sans-serif;">先讲一下shiro配置吧。</span>

需要jar包：

shiro-all-1.2.4.jar

ehcache-2.7.2.jar

slf4j-log4j12-1.6.1-javadoc.jar

slf4j.api-1.6.1.jar

log4j-1.2.15.jar

都是相互依赖的包。

配置文件：spring-shiro.xml

从<bean id="monitorRealm" class="com.test.util.MonitorRealm"/>可以看出我们需要一个java类来控制验证，
