Question

我有一个叫做oozies的骡子工作流程＆＃39; http服务启动一个工作，但我需要存储oozie在数据库中给出的工作ID。我实现了这个，但是一旦我转换了Oozie的响应，我就得到了一个例外。

无法应用转化。 Payload是ReleasingInputStream。

您正在将输入流应用于字符串变换器两次：

responseTransformer-refs="httptostring"

在这里

<object-to-string-transformer />

另外我猜你有一个名为httptostring的错误转换器。删除它或只删除responseTransformer-refs。

无法在mule中转换http响应
