Question

重启tomcat时出现IOException。我尝试了exception loading sessions from persistent storage

中建议的各种解决方案

他们都没有解决问题。我尝试取消注释context.xml中的<Manager pathname=""/>。没有帮助。

建议的另一个解决方案是使类实现Serialiable。我不想那样做。

我的目标是让Tomcat坚持这些会话。我正在使用Tomcat 7.0.54。

以下是堆栈跟踪。请帮忙。

解决此问题的另一种方法可能是使用Spring Session，它提供了一个可以以可配置方式持久化的替换HttpSession对象。可以使用各种持久性方法，例如， Redis，JDBC或内存映射。默认情况下，他们（或至少其中一些）可能希望项目可序列化，但实现更加可定制，因此您可以设置一个序列化程序来剥离不可序列化的对象，剩下的就是其余的（例如）。
