如何解决Apache Shiro中的logout方法抛出的UnknownSessionException？

Question

大家下午好！我在JSF中有一个使用Apache Shiro身份验证的项目。 login方法工作正常，但是logout方法抛出UnknownSessionException。

这是我对pom.xml（Maven）的依赖：

<!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-core -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.3.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-web -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
            <version>1.3.2</version>
        </dependency>

Answer 1

退出后可以发出重定向吗？我已经和Faces做了一段时间，所以我不确定你看到的请求流程。基本上，您希望注销请求是重定向之前发生的 last 事件。

Answer 2

谢谢你的回答。做一些研究，我可以解决问题。首先，我在Shiro.ini中评论了这些内容：

sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager 
securityManager.sessionManager = $sessionManager 
securityManager.sessionManager.globalSessionTimeout = 3600000

之后，我实现了javax.servlet.http.HttpSession来获取当前会话，如下所示：

HttpSession session = (HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false);

最后，我做了一个session.invalidate（），并在页面中进行了重定向，如下所示：

session.invalidate();
FacesContext.getCurrentInstance().getExternalContext.redirect("faces/paginaLogin.xhtml");

注销方法的最终版本：

  public void logout(){
        try{
          Subject currentUser = SecurityUtils.getSubject();
          HttpSession session=(HttpSession)FacesContext.getCurrentInstance().getExternalContext().getSession(false);
          if(currentUser.isAuthenticated()){
              session.invalidate();
 FacesContext.getCurrentInstance().getExternalContext().redirect("faces/paginalogin.xhtml"); 

        }
    }catch(Exception e){
            e.printStackTrace();
                    FacesContext.getCurrentInstance().addMessage(null,
                            new FacesMessage(FacesMessage.SEVERITY_ERROR, "Erro: ", e.getMessage()));
        }
    }
