spring-cloud-dataflow-server-local 要为 MySQL 启动？
spring-cloud-dataflow-server-local to start for MySQL?
我正在使用 Spring 批处理 处理 Spring 数据流。在这个例子中，我已经下载了 spring-cloud-dataflow-server-local-1.7.4.RELEASE，并且只是 运行 它 java -jar spring-cloud-dataflow-server-local-1.7.4.RELEASE.jar ，但它只是尝试仅连接到 H2 数据库。
有什么办法可以在 MySQL 开始吗？

您需要在启动服务器时设置适当的数据源属性：
java -jar spring-cloud-dataflow-server-local/target/spring-cloud-dataflow-server-local-1.7.4.RELEASE.jar \
--spring.datasource.url=jdbc:mysql://localhost:3306/mydb \
--spring.datasource.username= \
--spring.datasource.password= \
--spring.datasource.driver-class-name=org.mariadb.jdbc.Driver &
更多信息可以参考文档here
作为旁注，请考虑切换到更高版本的 SCDF，因为 1.7.x 相对较旧。
我正在使用 Spring 批处理 处理 Spring 数据流。在这个例子中，我已经下载了 spring-cloud-dataflow-server-local-1.7.4.RELEASE，并且只是 运行 它 java -jar spring-cloud-dataflow-server-local-1.7.4.RELEASE.jar ，但它只是尝试仅连接到 H2 数据库。
有什么办法可以在 MySQL 开始吗？
