尝试在工作流元数据和下面保存一些属性是我正在使用的代码片段 .

try {
    if (workItem.getWorkflowData().getPayloadType().equals("JCR_PATH")) {
        addValuesToMetadata(workItem, workflowSession,metaDataMap);
    }

    MetaDataMap wfMetaData=workItem.getWorkflowData().getMetaDataMap();
    Set<String> keys=metaDataMap.keySet();
    for (String key : keys) {
        if(key.startsWith("xyz")){
            wfMetaData.put(key, metaDataMap.get(key));
        }
    }

    workflowSession.updateWorkflowData(workItem.getWorkflow(), workItem.getWorkflowData());
} catch (Exception e) {
    e.printStackTrace();
}

我没有关闭会话，但它抛出以下异常 .
