Question

当我使用mulesoft调用带有“clob”的存储过程作为数据类型将xml数据插入数据库时，我面临此异常，它在oracle上显示异常。这是我的配置文件

Answer 1

请粘贴您的配置文件，因为类型转换是在作为clob传递之前，您需要的数据是字符串格式。

Answer 2

请尝试使用groovy组件并添加如下代码。

clobTest = (java.sql.Clob)payload.your_field bodyText = clobTest.getCharacterStream() targetString = org.apache.commons.io.IOUtils.toString(bodyText) payload.PAYLOADHEADERS=targetString return payload

Answer 3

程序参数中缺少

逗号，现在它的工作正常，感谢您的回复

org.mule.api.MessagingException：com.mulesoft.weave.reader.ByteArraySeekableStream无法强制转换为oracle.sql.CLOB
