我的新项目有问题，我收到这个我无法解决的错误，我在github上加载项目我认为这是一个配置问题。

https://github.com/DeAngelisLuca/Traccialo

application.properties 

spring.datasource.url= jdbc:postgresql://localhost/traccialo 
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.hibernate.ddl-auto=create-drop

spring.datasource.driverClassName=org.postgresql.Driver

spring.jpa.hibernate.hbm2ddl.auto=update

spring.jpa.hibernate.show_sql=true
hibernate.temp.use_jdbc_metadata_defaults false

答案 0 :(得分：0)

这个例外只发生在jdbc驱动程序4不匹配时（我想是这样，我之前已经讨论过了），正如你所知，hibernate是一个ORM工具，所以要创建一个连接，它需要来自的一些元数据信息。数据库中。

您可以将此行添加到application.properties

中来禁用此功能 
hibernate.temp.use_jdbc_metadata_defaults = false

如果您有hibernate.cfg.xml作为配置文件，那么您可以将此行添加到配置文件

hibernate.cfg.xml文件添加以下属性

<property name="hibernate.temp.use_jdbc_metadata_defaults">false</property>
  

注意： - 如果您发现application.properties键值对必须与=（赋值运算符）分开。请将此添加到您的代码中

希望这会帮助你。谢谢:)）
