java - "to com.zaxxer.hikari.HikariDataSource:"Springboot下绑定(bind)属性失败

Question

我已经添加了 ojdbc ddriver 并将依赖项包含在 pom 中，但我仍然收到标题中提到的错误。请帮忙。

之前我使用本地 postgres 数据库运行了该应用程序。现在尝试连接远程oracle db，遇到了这个问题。我已登录必要的防火墙。应用程序启动并按照 postgresdb 执行的方式执行。

当我尝试立即启动我的应用程序时，我收到以下日志 -

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

应用程序属性 -

##Postgres settings
##spring.datasource.url=jdbc:postgresql:*****
##spring.datasource.username=*****
##spring.datasource.password=*****
##spring.jpa.database-platform = org.hibernate.dialect.PostgreSQLDialect
spring.jpa.hibernate.ddl-auto = none
spring.jpa.hibernate.show-sql=true

# Oracle settings
spring.datasource.url=jdbc:oracle:*****
spring.datasource.username=*****
spring.datasource.password=*****
spring.datasource.driver-class=oracle.jdbc.driver.OracleDriver

# HikariCP settings
spring.datasource.hikari.connection-timeout=60000
spring.datasource.hikari.maximum-pool-size=5

#spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

我得到了解决方案或修复。我在 application.properties 中添加了以下属性

spring.datasource.driver-class=oracle.jdbc.driver.OracleDriver

并在项目结构的模块中显式指定驱动程序(ojdbc8)。现在可以了!!!谢谢大家的帮助!!
