Question

我尝试通过此连接将Postgresql与Spring云数据流一起使用：

java -jar spring-cloud-dataflow-server-2.2.2.BUILD-SNAPSHOT.jar --spring.datasource.url=jdbc:postgresql://localhost:5432/test --spring.datasource.username=postgres --spring.datasource.password=root --spring.datasource.driver-class-name=org.postgresql.Driver

，但未考虑此参数。

我是Spring Cloud数据流的新手。

您与我如何使用Postgres凭据启动SCDF之间的唯一区别是，URL的值部分用单引号引起来了。

启动Postgres：

docker run --name test-postgres -d -p 5432：5432 -e POSTGRES_PASSWORD = spring -e POSTGRES_USER = spring -e POSTGRES_DB = dataflow postgres：10

启动SCDF：

java -jar spring-cloud-dataflow-server / target / spring-cloud-dataflow-server-2.3.0.BUILD-SNAPSHOT.jar --spring.datasource.url ='jdbc：postgresql：// localhost： 5432 / dataflow'--spring.datasource.username = spring --spring.datasource.password = spring --spring.datasource.driverClassName = org.postgresql.Driver

日志： （查找“ Postgres”）
