我尝试通过以下连接将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。请您能帮我，我是Spring Cloud数据流的新手。谢谢
和您之间以及使用Postgres凭据启动SCDF的唯一区别是URL的值部分用单引号引起来。
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”）
