问题描述:
手机APP端两个用户同时评论一篇文章该篇文章的评论量只增加了1。
问题代码:
XContentBuilder updateSource = XContentFactory.jsonBuilder().startObject()
.field("atdCnt", atdCnt + 1).endObject();
updateResponse = getTransportClient()
.prepareUpdate(esProperties.getES_Index(), esProperties.getES_Type(), docID)
.setRouting(esProperties.getES_Routing()).setDoc(updateSource).get();
解决:
UpdateRequest updateRequest = new UpdateRequest();
updateRequest.index(esProperties.getES_Index());
updateRequest.type(esProperties.getES_Type());
updateRequest.id(docID);
updateRequest.routing(esProperties.getES_Routing());
updateRequest.script(new Script("ctx._source.cmtCnt++")).retryOnConflict(2);
updateResponse = getTransportClient().update(updateRequest).get();
