Question

我已经配置了Spring Boot rest应用程序。我已经用jood来交流PostgreSQL数据库。

这是我的pom.xml内容。

我在属性文件中也有以下配置。

spring.datasource.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/aaaa?currentSchema=public
spring.datasource.username=aaaa
spring.datasource.password=aaaa
spring.jooq.sql-dialect=Postgres 
spring.datasource.dbcp2.initial-size=7
spring.datasource.dbcp2.max-total=20
spring.datasource.dbcp2.pool-prepared-statements=true

启动应用程序时，我在控制台中收到以下错误：

说明：无法配置数据源：未指定“ URL”属性，并且无法配置任何嵌入式数据源。原因：无法确定合适的驱动程序类别行动：考虑以下：如果要使用嵌入式数据库（H2，HSQL或Derby），请将其放在类路径中。如果您要从特定配置文件加载数据库设置，则可能需要激活它（当前没有配置文件处于活动状态）。
