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！
