shiro + jfinal， 重写shiro 的 authc 过滤器后，过滤器无效:配置报错 

解决么了，IBM的文章“ http://www.ibm.com/developerworks/cn/java/j-lo-shiro/” 是错的。在

FormAuthenticationFilter处，认证方法错误。至少再shiro1.2.2版本下

public class MyJdbcAuthzService implements JdbcAuthzService {
  @Override
  public Map<String, AuthzHandler> getJdbcAuthz() {
    //加载数据库的url配置
    Map<String, AuthzHandler> authzJdbcMaps = new HashMap<String, AuthzHandler>();
//    Map<String, AuthzHandler> authzJdbcMaps = new TreeMap<String, AuthzHandler>(
//        new Comparator<String>() {
//          public int compare(String k1, String k2) {
//            return new Integer(k2.length()).compareTo(k1.length());
//          }
//
//        });
    //遍历角色
    List<Role> roles = Role.dao.findAll();
    List<Permission> permissions = null;
    for (Role role : roles) {
      //角色可用
      if (role.getDate("daleted_at") == null) {
        permissions = Permission.dao.findByRole("", role.get("id"));
        //遍历权限
        for (Permission permission : permissions) {
          //权限可用
          if (permission.getDate("daleted_at") == null) {
            if (permission.getStr("url") != null && !permission.getStr("url").isEmpty()) {
              authzJdbcMaps.put(permission.getStr("url"), new JdbcPermissionAuthzHandler(permission.getStr("value")));
            }
          }
        }
      }
    }
    return authzJdbcMaps;
  }
}

//如果系统不重启需要加载新权限到全局过滤
            ShiroKit.addJdbcAuthz(authority.getStr("url"),authority.getStr("auth_key"));
