Spring Boot - Hikari 管家线程在升级后关闭时无法停止

Question

我们最近从 Spring Boot 2.5.14 升级到 2.7.8.

升级后，我们现在在关闭应用程序时出现错误：

2023-02-27 11:09:40.473  WARN [on(2)-127.0.0.1] o.a.c.loader.WebappClassLoaderBase       [] [] [] : The web application [ROOT] appears to have started a thread named [HikariPool-1 housekeeper] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:

我们为 JPA 做了非常少的配置。

我们在属性文件中指定spring数据源属性：

spring.datasource.url=jdbc:sqlserver...
spring.datasource.username=...
spring.datasource.password=..
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=none

我们像这样编码我们的存储库

import org.springframework.data.jpa.repository.JpaRepository;

public interface OurRepository extends JpaRepository<OurEntity, String> {
    
    List<OurEntity> findByProperty(String property);
}

我在很多地方搜索了这个错误，我找到的唯一建议是在bean配置上添加destroyMethod="close"。然而，我们没有显式定义一个 DataSource bean，我们依赖于 Spring Boot 的实现，我相信它应该适当地结束。

知道为什么我们在关闭应用程序时突然收到此错误吗？ 关于该错误的危害程度有何评论？ 有什么缓解的建议吗？
