Key concepts of @xuguokun1986 code

Understand the following nouns, as mentioned in the previous article, indexed (indices)-> databases, types (types)-> tables, documents (documents)-> rows, fields (Fields)-> columns;-> The table that follows represents the basic relational database. The basic dependent jar package is contained in the corresponding Lib folder under the Elasticsearch folder, where the JSON file relies on the download address http://wiki.fasterxml.com/JacksonDownload of the jar package. problems encountered and solutions

Client = new Transportclient (). addtransportaddress (New inetsockettransportaddress ("192.168.203.148", 9200);

Error no node available

WORKAROUND: Here 9200 rewrite the 9300 code to create the index and insert the data code as shown below:
