文章标签 java springboot 异常 自定义 spring 集成 filter shiro 遭遇

本文主要是介绍springboot集成shiro遭遇自定义filter异常，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

首先简述springboot使用maven集成shiro
1、用maven添加shiro

    <!--shiro--><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-web</artifactId><version>1.4.0</version></dependency><dependency><groupId>org.apache.shiro</groupId><artifactId>shiro-spring</artifactId><version>1.4.0</version></dependency>

2、配置shiro

import com.yuntu.intelligent.log.service.QueryPermissionService;
import com.yuntu.intelligent.log.service.shiro.authc.AccountSubjectFactory;
import com.yuntu.intelligent.log.service.shiro.filter.AuthenticatedFilter;
import com.yuntu.intelligent.log.service.shiro.filter.QueryLimitFiter;
import com.yuntu.intelligent.log.service.shiro.realm.AccountRealm;
import org.apache.shiro.cache.CacheManager;
import org.apache.shiro.cache.MemoryConstrainedCacheManager;
import org.apache.shiro.codec.Base64;
import org.apache.shiro.session.mgt.SessionManager;

import java.util.Map;/*** shiro权限管理的配置*/

}

4、重点记录filter配置中出现的问题。
如上代码，我有2个自定义的过滤器，AuthenticatedFilter可以抛开spring运行，而QueryLimitFiter想使用一些spring管理的bean，所以一开始QueryLimitFiter是使用@Component注释并且在ShiroConfig的@Bean方法中将其注入并配置进shiro的过滤器链。
在使用的时候，原定只是在个别uri触发的QueryLimitFiter，所有uri都会触发它，反而AuthenticatedFilter失效了。查找原因，找到spring的filter链如图，这是借用别人的图，我的图是将accessTokenFilter替换为queryLimitFiter：
这里写图片描述
总之就是自定义的过滤器QueryLimitFiter居然在shiroFilter之外而且运行在shiroFilter之前了。。。

5、解决方案，如上代码，将QueryLimitFiter不交给spring托管，使用new的方式添加到shiro的过滤器链中就没有问题了。出现原因可能是spring会自动将我们自定义的filter加载到它的过滤器链中（待深究！）。

这篇关于springboot集成shiro遭遇自定义filter异常的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
