shiro unauthorizedUrl页面不跳转问题

  最近使用shiro框架控制用户权限，用户权限认证未通过时，无法跳转到unauthorizedUrl对应的页面，直接抛出了异常

解决方法：

1、mvc

none_authority

2、web.xml

 <error-page>
       <error-code>500error-code>
       <location>/error.jsplocation>
 error-page>

原因：

shiro的源代码ShiroFilterFactoryBean.java

 private void applyUnauthorizedUrlIfNecessary(Filter filter) {
     String unauthorizedUrl = getUnauthorizedUrl();
     if (StringUtils.hasText(unauthorizedUrl) && (filter instanceof AuthorizationFilter)) {
         AuthorizationFilter authzFilter = (AuthorizationFilter) filter;
         //only apply the unauthorizedUrl if they haven't explicitly configured one already:
         String existingUnauthorizedUrl = authzFilter.getUnauthorizedUrl();
         if (existingUnauthorizedUrl == null) {
             authzFilter.setUnauthorizedUrl(unauthorizedUrl);
         }
     }
 }

定义的filter必须满足filter instanceof AuthorizationFilter，只有perms，roles，ssl，rest，port才是属于AuthorizationFilter，而anon，authcBasic，auchc，user是AuthenticationFilter，所以unauthorizedUrl设置后页面不跳转
