我安装了scdf，并且可以通过url和shell正确访问它。问题是，一旦我重新启动系统，我将失去所做的一切（看到使用基础H2）。当我尝试如下使用Postgresql时：
java -Dloader.path=lib -jar spring-cloud-dataflow-server-2.2.1.RELEASE.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 &. I have the following error:

您能帮我吗！
似乎根本原因指向：
Driver org.postgresql.Driver声称不接受jdbcUrl，jdbc：postgresql：// localhost：5432
我注意到您的价值部分中有明显的事情。在数据库模式[ee：/ test]之前和之后似乎都有一个“空格”。您可能想尝试以下方法：
java -Dloader.path=lib -jar spring-cloud-dataflow-server-2.2.1.RELEASE.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
除此之外，我认为您的属性中没有任何错误，但是我看到有些人成功地用双引号将值引起来了[请参阅：example]。
也许您也可以尝试：
-spring.datasource.url =“ jdbc：postgresql：// localhost：5432 / test”
