SpringBoot集成JJWT停止应用时出现内存泄漏警告求助

我之前使用旧版本JJWT与SpringBoot配合运行正常，但切换到SpringBoot 2.7.8和JJWT 0.11.2版本后，停止应用时总会出现以下警告：

2023-03-22 10:57:39.430  INFO 7316 --- [on(7)-127.0.0.1] inMXBeanRegistrar$SpringApplicationAdmin : Application shutdown requested.

提示Web应用启动的HikariPool-1 housekeeper线程未停止，极可能造成内存泄漏。同时停止应用时会生成HeapDump。

            return headerAuth.substring(7, headerAuth.length());
        }
        return null;
    }

}
