使用 UI spring 云数据流中的多个参数启动任务时出错
Error when launching tasks with multiple arguments from UI spring cloud dataflow
我有一个带有 2 个参数的批处理作业。当我在 运行 直接 jar 文件时传递这些参数时，它起作用了。此外，当我通过 spring 云数据流的 shell 传递这些参数时，它起作用了：
dataflow:>task launch --name adv-load --arguments "appnexus_seat=SEAT_MIQ_1 last_modified=2018/08/10"
Launched task 'adv-load'
但是，当我在 运行 任务形成 UI 时传递类似的参数时，它失败了。例如，在 UI 中，我传递了：appnexus_seat & last_modified 作为 2 个键，它们具有与上面相同的值但不同的日期，因此它认为它不是同一个工作。这失败了。
不过我确实设法找到了问题所在。当我通过 shell 运行 任务时，在日志中我得到这个：

如果您查看差异，您会发现当我 运行 通过 shell 它在两个参数之间给出 space 而当我 运行它通过 Ui 它没有。不给出此 space 会导致问题，因为第一个参数的值变为 "SEAT_MIQ_1,last_modified=2018/08/10" 而不是 "SEAT_MIQ_1" 而 last_modified 是另一个参数。
请告诉我如何解决这个问题。谢谢。 :)
当您 运行 来自 UI 的任务时，您需要在单独的字段中指定每个参数：
这会正确地将参数传递给您的任务。
