Java Spring Boot应用程序在运行后自动关闭

每当我尝试运行我的应用程序时，我都会收到此日志。我尝试在application.properties上添加更多参数（如

spring.jpa.hibernate.ddl auto=update

），但这只会破坏应用程序并显示更多错误。我找不到办法把这个修好

这是我的pom.xml 我的pom.xml上是否有任何配置错误的内容

Spring引导应用程序不会自行关闭，但Hikari连接会关闭。我发现数据源URL有一个问题：我注意到在

…devops\u db？

和

usesl=false…

部分之间有一条新的线，这些部分不应该出现

复制并粘贴此内容（即用以下行替换属性文件的前两行）：

---

您可以将

org.springframework

的日志记录级别设置为

debug

以及

spring.jpa.hibernate.ddl auto=none

并共享结果吗。

---

您还可以共享数据源配置吗。我尝试了你的建议，但它仍然关闭了Hikari连接。还有什么我可能错过或误解的吗？嗯。。也许是依赖关系。我觉得您不需要

spring boot starter tomcat

和

spring boot starter jdbc

。您的日志输出显示：

org.hibernate.engine.transaction.jta.platform.internal.NoJtaPlatform

-这个答案可能相关：

spring.datasource.url=jdbc:mysql://localhost:3306/?user=root/devops_db?
useSSL=false&allowPublicKeyRetrieval=true&useSSL=false&serverTimezone=UTC

spring.datasource.username=username
spring.datasource.password=password

server.error.include-stacktrace=never
spring.jackson.serialization.indent-output=true

server.port=8090

spring.datasource.url=jdbc:mysql://localhost:3306/?user=root/devops_db?useSSL=false&allowPublicKeyRetrieval=true&useSSL=false&serverTimezone=UTC
