org.elasticsearch.index.query.QueryShardException: failed to find geo_point field [geo]错误原因

报错意思是   错误的找不到  geo_point 类型， 名字叫做  geo 的字段

先从我创建索引说起。

1：用插件创建个名为  amapaa的索引，里面的 mappings 都是为空的

 2：直接执行新增数据操作，系统会 自动(动态)帮我们执行mapping 对象和es索引之间的关系连接

@Data
@Document(indexName = "amap", type = "_doc", createIndex = false)
public class User {

    @Id
    private Long userId;

    @Field(store = true)
    private String userName;

    @Field(store = true)
    @GeoPointField
    private GeoPoint geo;

    @Field(store = true)
    private String place;


    @Override
    public String toString() {
        return "User{" +
                "userId=" + userId +
                ", userName='" + userName + '\'' +
                ", geo='" + geo + '\'' +
                ", place='" + place + '\'' +
                '}';
    }
}

3：但是 geo_point 类型并不会映射正确 ，映射成了float 类型 

4：在查询的时候就会抛出异常，第一个异常信息有误导到，还以为分片出现问题。 但是第二个说的就比较清楚了，也是问题的解决关键

 5：删除掉错误的索引，用请求的方式 重新创建，提前指定好  geo 字段为  geo_point 类型

{
    "mappings": {
        "_doc": {
            "properties": {
                "geo": {
                    "type": "geo_point"
                }
            }
        }
    }
}

6： 重新增加一条数据测试，      其他字段动态映射进去， geo_point 类型在我们创建索引提前指定没有覆盖。   问题解决
