我有一个spring-boot微服务在kube集群中运行。它运行正常，但间歇性抛出错误：无法从文件：/app/truststore加载信任库。应用程序运行良好，但在中途创建新连接时会抛出错误。从我的调试点看这段代码 tm.getAcceptedIssuers() 正在返回nullhttps://github.com/mysql/mysql-connector-j/blob/release/8.0/src/main/core-impl/java/com/mysql/cj/protocol/exportcontrolled.java#l586
我正在使用hibernate，但是所有的实体都被标记为不可变的，因为这个应用程序是只读的。
