我对Elasticsearch有点陌生，我有一个正则表达式，我正在尝试使用Java插入 flex 搜索，并且遇到了我尝试使用/作为转义字符的解析错误，但仍然失败。有人可以告诉我我想念的吗？
String workflow = "{\"WORKFLOW_ID\":1,\"NAME\":\"Test Workflow\",\"DESCRIPTION\":\"This workflow will be used for testing\",\"COMPANY_ID\":237,\"SOURCE_ID\":1,\"NODES\":[{\"NODE_ID\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf4\",\"POSITION_X\":0,\"POSITION_Y\":120,\"WORKFLOW_ID\":1,\"NAME\":\"Start Node\",\"TYPE\":\"START_NODE\",\"COMPANY_ID\":237,\"CONNECTIONS_TO\":[{\"FROM\":\"a\",\"TO_NODE\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf5\"}],\"VALUES\":{}},{\"NODE_ID\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf5\",\"POSITION_X\":120,\"POSITION_Y\":240,\"WORKFLOW_ID\":1,\"NAME\":\"Route Node1\",\"TYPE\":\"ROUTE_NODE\",\"COMPANY_ID\":237,\"CONNECTIONS_TO\":[{\"FROM\":\"a\",\"TO_NODE\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf6\"},{\"FROM\":\"b\",\"TO_NODE\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf7\"}],\"VALUES\":{\"VARIABLE\":{\"NAME\":\"Subject\",\"TYPE\":\"String\"},\"CONDITIONS\":[{\"ORDER\":0,\"OPERATOR\":\"Regex\",\"VALUE\":\"\\[#([0-9]+)\\]\",\"TO_NODE\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf6\"},{\"ORDER\":1,\"OPERATOR\":\"\",\"VALUE\":null,\"TO_NODE\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf7\"}]}},{\"NODE_ID\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf6\",\"POSITION_X\":120,\"POSITION_Y\":240,\"WORKFLOW_ID\":1,\"NAME\":\"Work action1\",\"TYPE\":\"WORK_ACTION_NODE\",\"COMPANY_ID\":237,\"CONNECTIONS_TO\":[],\"VALUES\":{\"WORK_ACTION_TYPE\":\"Ticket\",\"STATUS\":\"New\"}},{\"NODE_ID\":\"node-220ae87b-f74d-22a5-8661-a1d189983bf7\",\"POSITION_X\":120,\"POSITION_Y\":240,\"WORKFLOW_ID\":1,\"NAME\":\"Work action2\",\"TYPE\":\"WORK_ACTION_NODE\",\"COMPANY_ID\":237,\"CONNECTIONS_TO\":[],\"VALUES\":{\"WORK_ACTION_TYPE\":\"Ticket\",\"STATUS\":\"Open\"}}]}";
这是我用来将数据放入elasticsearch的代码
IndexResponse rescreate = Consumer.client.prepareIndex("workflows", "workflow").setSource(workflow.toString(), XContentType.JSON).get();
那是我的jsonobject，这是我得到的错误，我正试图传递的正则表达式为\ [＃([0-9] +)\]。
最佳答案
对于任何可能遇到此问题的人。我将String格式的json对象再次转换为String，因此遇到了此问题。

IndexResponse rescreate = Consumer.client.prepareIndex(“workflows”，“workflow”)。setSource(workflow，XContentType.JSON).get();
仅执行工作流程即可。 working.toString()导致问题
