上面的代码工作正常,但它在下载的文件中返回=== Audit Log ===。取而代之的是,我需要显示在rest组件生成的附件级别定义的有效负载。
审计流程的目的是记录数据库中成功/失败的状态,该状态不应返回任何内容。如果我删除<set-payload value="===Audit Log ===" name="AuditStatus" doc:name="Status"/>
它开始返回java.lang.Number

在将其设置为异步后出现以下错误:

后的工作代码的最终更改<flow name="audit" doc:name="audit">
<async>
<db:insert config-ref="QB_Oracle_Configuration" doc:name="Audit" transactionalAction="NOT_SUPPORTED">

答案 0 :(得分:1)
<set-payload value="#[message.payload]" doc:name="Set Payload"/>
:它将消息有效负载设置为自身,这是无用的。<flow-ref name="audit" doc:name="audit"/>
包裹在async
范围内,以便其响应不会混淆JAX-RS组件的响应。audit
流,否则请删除其中的http:inbound-endpoint
。
