spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
参考：
我有类似的问题。 我遵循这个解决方案，它对我有用

# Disable feature detection by this undocumented parameter. Check the org.hibernate.engine.jdbc.internal.JdbcServiceImpl.configure method for more details. spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults = false # Because detection is disabled you have to set correct dialect by hand. spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect
通过添加hibernate.properties解决
hibernate.jdbc.lob.non_contextual_creation=true
使用application.properties其他解决方案不起作用。 这也可以通过XML hibernate.cfg.xml完成
Spring Boot版本：2.0.2.RELEASE
组
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true
在你的财产。 对于Spring boot 2.0.x
通过使用以下Yaml配置解决：
spring: jpa: properties: hibernate: jdbc: lob: non_contextual_creation: true database-platform: org.hibernate.dialect.PostgreSQL9Dialect
