我对WSO2 BPS 3.2.0和BPEL都很陌生。我使用bpel4people扩展创建了一个用于触发HumanTask的BPEL流程。为此我拿了BPS随附的样本humantask。我可以成功解雇任务。但是一旦我完成任务，我的bpel过程就不会收到任务的响应。是否有任何特殊的程序来获得休息？这是我的bpel过程和HumanTask的WSDL文件。

答案 0 :(得分：0)
最后我能做到。
我们需要做的是将correlationFilter属性添加到deploy.xml文件中的相应提供活动
通过添加此命名空间将提供b4pFilter
xmlns:b4p="http://docs.oasis-open.org/ns/bpel4people/bpel4people/200803"
<provide partnerLink="b4p" correlationFilter="b4p:b4pFilter">
<service name="biApprove:ClaimServiceCB" port="ClaimPortCB"/>
</provide>
deploy.xml的完整代码
<?xml version="1.0" encoding="UTF-8"?>
<deploy xmlns="http://www.apache.org/ode/schemas/dd/2007/03"
xmlns:biApprove="http://www.example.com/claims/"
xmlns:sample="http://loits.com/bps/training"

<process-events generate="all"/>
<provide partnerLink="client">
