Question

我最近发现存储在AdapterSecurityContext中的mobilefirst 8服务器数据存在问题。我们使用方法getClientRegistrationData在自定义安全检查下将安全用户数据存储在AdapterSecurityContext中。它在Mobilefirst DevKit服务器上正常工作

ClientData clientData = adapterSecurityCheck.getClientRegistrationData();

clientData.getPublicAttributes().put(key, "hello");
adapterSecurityCheck.storeClientRegistrationData(clientData);

但是当我在Liberty服务器上运行相同的适配器或者我们安装它的ND服务器时，它给了我以下错误

com.ibm.mfp.server.core.sha red.MFPRESTException：409; headers = [MFP-Conflict =并发失败];体= {}

请参阅https://www.ibm.com/support/knowledgecenter/en/SSHS8R_8.0.0/com.ibm.worklight.apiref.doc/html/refjava-mfp-server/html/com/ibm/mfp/server/security/external/resource/AdapterSecurityContext.html。必须通过AdapterSecurityContext.getClientRegistrationData（），AdapterSecurityContext.getClientRegistrationData（String）或AdapterSecurityContext.findClientRegistrationData（ClientSearchCriteria）获取ClientData实例。如果在通过此请求获取注册数据后，并发请求会修改注册数据，则此方法会抛出一个运行时异常，该异常会自动报告给客户端，如HTTP状态409（冲突）。
