实现PathMatchingFilter shiro的过滤器如何在shiro之前执行呢

想定义过滤器存储 shrio sesssion 信息
继承PathMatchingFilter 还需要实现 implements ActionFilter 方法吗

package io.nutz.nutzsite.common.shiro.filter;

import io.nutz.nutzsite.common.bean.OnlineSession;
import io.nutz.nutzsite.common.constant.ShiroConstants;
import io.nutz.nutzsite.common.shiro.session.OnlineSessionDAO;
import org.apache.shiro.web.filter.PathMatchingFilter;
import org.nutz.ioc.loader.annotation.Inject;
import org.nutz.ioc.loader.annotation.IocBean;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**
 * 同步Session数据到Db
 *
 * @author ruoyi
 */
@IocBean
public class SyncOnlineSessionFilter extends PathMatchingFilter {
    @Inject
    private OnlineSessionDAO onlineSessionDAO;

    /**
     * 同步会话数据到DB 一次请求最多同步一次 防止过多处理 需要放到Shiro过滤器之前
     */
    @Override
    protected boolean onPreHandle(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {
        OnlineSession session = (OnlineSession) request.getAttribute(ShiroConstants.ONLINE_SESSION);
        // 如果session stop了 也不同步
        // session停止时间，如果stopTimestamp不为null，则代表已停止
        if (session != null && session.getUserId() != null && session.getStopTimestamp() == null) {
            onlineSessionDAO.syncToDb(session);
        }
        return true;
    }
}

为啥没有执行方法呢莫非是WebFilterFace不对

wendal

12楼•1834天前

getFilter应该return this

至于为啥没有执行

要么order不对，没放在shiro之前

要么超类的逻辑问题，因为Filter接口就一个方法，你覆盖的是超类的方法，并非Filter的方法， web容器并不会直接调用到

14楼•1833天前

WebFilterFace只能保证调用到Filter的doFilter方法, 其他方法是Filter实现类的事.

WebFilterFace的作用等同于web.xml里面声明个<filter>和<filter-mapping>

PS: 跟ActionFilter一点关系没有,实现ActionFilter没一点意义.

/login = anon
/sys/** = authc
/index = authc
/druid/** =authc
