# 二、错误原因 #

ES字段类型与Document实体类里的字段类型不一致

# 三、解决方案 #

把index.json文件里的ES字段类型与Java代码里的字段类型修改为一致即可。

例如我的index.json修改后的文件如下：

{
      "properties": {
        "title": {
          "type": "text",
          "analyzer": "ik_max_word",
          "search_analyzer": "ik_max_word"
        },
        "keywords": {
          "type": "text",
          "analyzer": "ik_max_word",
          "search_analyzer": "ik_max_word"
        },
        "description": {
          "type": "text",
          "analyzer": "ik_max_word",
          "search_analyzer": "ik_max_word"
        },
        "url": {
          "type": "keyword"
        },
        "imageUrl": {
          "type": "keyword"
        },
        "siteId": {
          "type": "long"
        },
        "siteType": {
          "type": "keyword"
        },
        "inputdate": {
          "type": "date"
        },
        "popularity": {
          "type": "long"
        },
        "district": {
          "type": "keyword"
        },
        "community": {
          "type": "text"
        },
        "sortNum": {
          "type": "long"
        }
      }
    }

对应的Java实体Document如下：

@Data
    @Document(indexName = "hot_estate", type = "hot_estate")
    @Mapping(mappingPath = "hotEstateIndex.json")
    public class HotEstateDocument{
        @Id
        private String contentId;
        /**
         * 标题
         */
        private String title;
        /**
         * 关键字
         */
        private String keywords;
        /**
         * 描述
         */
        private String description;
        /**
         * 内容url
         */
        private String url;
        /**
         * 封面多图
         */
        private String imageUrl;
        /**
         * 发布时间
         */
        private Date inputdate;
        /**
         * 站点id
         */
        private Long siteId;
        /**
         * 站点类型
         */
        private String siteType;
        /**
         * 人气
         */
        private Integer popularity;
        /**
         * 排序号
         */
        private Integer sortNum;
        /**
         * 行政区
         */
        private String district;
        /**
         * 小区
         */
        private String community;
    
        public static HotEstateDocument content2Document(TCmsContentVo content) {
            HotEstateDocument hotEstateDocument=new HotEstateDocument();
            BeanUtils.copyProperties(content,hotEstateDocument);
            return hotEstateDocument;
        }
    
    }

完结！
