春季启动中的非嵌入式PostgreSQL

Question

我正在尝试在Spring Boot中使用非嵌入式PostgreSQL数据库。 但是，当我尝试运行应用程序“ mvn spring-boot：run”时，该应用程序无法以以下消息启动：

无法确定数据库类型NONE的嵌入式数据库驱动程序类

这些是我对pom.xml的依赖：

这是我在application.yml中的设置：

spring:
  profiles: dev
  application:
    name: resource-service
  jpa:
    database: POSTGRESQL
    datasource:
      platform: postgres
      url: jdbc:postgresql://${postgresqlHost:localhost}:${postgresqlPort:5432}
      username: ${postgresqlUsername:root}
      password: ${postgresqlPassword:SomePassword}
      driverClassName: org.postgresql.Driver

我找不到太多有关此的信息，这使我认为这可能真的很容易上手...

Answer 1

您需要正确提供数据库URL和驱动程序类名称

spring.datasource.url = <database source url>
spring.datasource.driver-class-name = <driver class name>

Answer 2

当您执行"mvn spring-boot:run"你不指定使用Spring启动dev的个人资料，同时要配置为数据源的属性dev简介：

profiles: dev

此外，在application.yml中，应引用属性： spring.datasource而不是Spring不使用的jpa.database.datasource 。

您应该写：

spring.datasource:
    driverClassName: org.postgresql.Driver
    url: jdbc:postgresql://${postgresqlHost:localhost}:${postgresqlPort:5432}
    ...

这是有关此方法的文档参考。
