apache - Java/jersey Web 服务需要重启(错误代码 500)

Question

我正在使用 Java、jersey、Apache tomcat eclipse 开发 REST 网络服务。 在我关闭播种系统并回家之前，一切似乎都运行良好。 Web 服务部署在服务器上。当我第二天尝试访问 Web 服务时(在 10-12 小时不活动后)，服务器返回 500 错误。一旦我重新启动 tomcat，一切都会重新开始工作。我缺少一些配置吗？

休眠配置

Answer 1

您的 SQL 状态 08003 表明“连接不存在”。

可能是你的hibernate配置有问题(超时之类的)

请检查!
