es 创建动态索引(一)

es 实体类

/**
 * @author river
 * @date 2019/2/27 14:47
 **/
@Data
@Document(indexName = "student-" + "#{ T(com.river.es.entity.Student).dateStr() }",

        type = "student",
        shards = 2,
        replicas = 1, refreshInterval = "-1")
public class Student {

    @Id
    private String id;

    private String name;

    private Integer age;

    private String desc;

    public static String dateStr()
    {
        return DateUtil.now().replace(" ","");
    }
}

索引的后缀是时间，精确到秒钟
测试方法，每隔一秒钟插入一条数据。

    @Test
    public void testsave() throws InterruptedException {
        for (int i = 0; i < 5 ; i++) {
            Thread.sleep(1000);
            Student student = new Student();
            student.setName("name:"+i);
            studentService.save(student);
        }
    }

通过kibana 去查询结果

GET /student*/_search?pretty
{
  "query": {
    "match_all": {}
  }
}

结果如下 发现的确创建了多个索引
