启动时候创建的 索引mapping

和save时候 创建的 索引mapping
之间的区别测试。

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;

    @Field(type = FieldType.Keyword)
    private String name;

    @Field(type = FieldType.Integer)
    private Integer age;

    private String desc;

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

springboot 启动后创建的mapping为

{
  "student-2019-05-3109:18:49": {
    "mappings": {
      "student": {
        "properties": {
          "age": {
            "type": "integer"
          },
          "name": {
            "type": "keyword"
          }
        }
      }
    }
  }
}

save时候发现没有 自己（es）默认创建的

  "student-2019-05-3109:25:17": {
    "mappings": {
      "student": {
        "properties": {
          "age": {
            "type": "long"
          },
          "desc": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          },
          "name": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          }
        }
      }
    }
  }

不一样，这个问题 可能导致，下次启动失败。因为es不支持 修改 mapping
