关于shiro错误的分析
错误提示:

org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code,either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton.  This is an invalid application configuration.


错误原因:

在web.xml中配置shiro filter的时候,shiro filter放置位置放到了struts2 filter后面


原因分析:

如果使用struts2,那么在struts2加载静态资源的时候,需要将静态资源SecurityUtils也加载进去,如果将shiro filter放置位置放到了struts2 filter后面,那么必将导致无法加载到struts2中去,而后使用SecurityUtils.getSubject();的时候,导致出错,


解决办法:

shiro的filter应该放在struts2的 filter的上面

还可以在使用之前使用这种方式:即在SecurityUtils.getSubject();之前加入如下代码

Factory<securitymanager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
// 创建SecurityManager (根据配置创建SecurityManager实例)
SecurityManager security = factory.getInstance();
SecurityUtils.setSecurityManager(security);</securitymanager>
Copy after login
这个想必不用解释了吧
