如何使用 Java High Level Rest Client API 映射

Question

我正在使用 ES 7.2。下面是来自 ES 的示例查询结果。它有两个字段 STATUS 和 SERVICE_ID：{{  "took" : 4,  "timed_out" : false,  "_shards" : {    "total" : 1,    "successful" : 1,    "skipped" : 0,    "failed" : 0  },  "hits" : {    "total" : {      "value" : 106,      "relation" : "eq"    },    "max_score" : 1.0,    "hits" : [      {        "_index" : "myindex",        "_type" : "_doc",        "_id" : "ENXDrWsBF759w7WDGxK4",        "_score" : 1.0,        "_source" : {          "STATUS" : "10",          "SERVICE_ID" : "916"        }      },      {        "_index" : "myindex",        "_type" : "_doc",        "_id" : "EdXDrWsBF759w7WDGxK4",        "_score" : 1.0,        "_source" : {          "STATUS" : "10",          "SERVICE_ID" : "916"        }      }    ]  }}我想将它映射到下面的 Java Bean“MyBean”：public class MyBean {  String SERVICE_ID;  String STATUS;public String getSERVICE_ID() {    return SERVICE_ID;}public void setSERVICE_ID(String sERVICE_ID) {    SERVICE_ID = sERVICE_ID;}public String getSTATUS() {    return STATUS;}public void setSTATUS(String sTATUS) {    STATUS = sTATUS;}}我已经使用 ObjectMapper 的 jackson 库尝试了下面的映射，但它有以下异常：        try {                    SearchResponse searchResponse1 = client.search(searchRequest, RequestOptions.DEFAULT);            ObjectMapper mapper = new ObjectMapper();            java.util.List<MyBean> lst = new ArrayList<MyBean>();            for(SearchHit hit : searchResponse1.getHits().getHits()) {//here below, i have the exception                MyBean s = mapper.readValue(hit.getSourceAsString(), MyBean.class);                lst.add(s);            } 以下是例外情况：com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "STATUS" (class MyBean), not marked as ignorable (2 known properties: "status",  "service_ID") at [Source: (String)"{"STATUS":"11"}"; line: 1, column: 12] (through reference chain: MyBean["STATUS"])你有什么主意吗？

Answer 1

这个怎么样？

public class MyBean {

    private String status;

    private String name;

 

    @JsonProperty("SERVICE_ID")

    public void setServiceId(String serviceId) {

        this.serviceId = serviceId;

    }

 

    @JsonProperty("SERVICE_ID")

    public String getServiceId() {

        return serviceId;

    }

    @JsonProperty("STATUS")

    public void setStatus(String status) {

        this.status = status;

    }

 

    @JsonProperty("STATUS")

    public String getStatus() {

        return status;

    }

}
