创建与给定json等效的SolrParams

Question

使用solrj 7.3.0版与此版本等效的GenericSolrRequest是什么：

SolrRequest v2request = new V2Request.Builder(String.format("/collections/%s/config", collectionName))
.withMethod(SolrRequest.METHOD.POST)
.withPayload(payload)
.build();

具有以下有效负载

{
  "update-requesthandler": {
    "name": "%s",
    "class": "solr.SearchHandler",
    "defaults": {
      "defType": "edismax",
      "rows": 100,
      "lowercaseOperators": true,
      "qf": "%s",
      "hl.fl": "*",
      "hl.requireFieldMatch": true,
      "lowercaseOperators": true
    }
  }
}

我想出了这一点，不确定如何设置参数以实现与V2 API相同的有效负载：

//ModifiableSolrParams params = new ModifiableSolrParams(); is that possible to use this class with nested fields in json ?

SolrRequest request = new GenericSolrRequest(SolrRequest.METHOD.POST, String.format("/%s/config", collectionName), params);

尝试：

ModifiableSolrParams params = new ModifiableSolrParams();
params.set("command", "update-requesthandler");
params.set("class", "solr.SearchHandler");
params.set(CommonParams.NAME, FREETEXT_REQUEST_HANDLER);
params.set("defType", "edismax");
params.set("lowercaseOperators", true);
params.set(CommonParams.ROWS, 100);
params.set("qf", qfValue);
params.set("hl.fl", "*");
params.set("hl.requireFieldMatch", true);


SolrRequest request = new GenericSolrRequest(SolrRequest.METHOD.POST, String.format("/%s/config", collectionName), solrParams);

request.process(solrClient);

并且在solr端导致异常：

Answer 1

检查以下代码是否适合您。

ModifiableSolrParams params = new ModifiableSolrParams();
params.set(CommonParams.WT, "json");
params.set(CommonParams.ROWS, 10);
params.set("hl", true);
params.set("hl.q", "pizza");
params.set("defType", "edismax");
params.set("hl.requireFieldMatch", true);

String url = "http://ip:8983/solr";
GenericSolrRequest request = new GenericSolrRequest(SolrRequest.METHOD.POST, "/select", params);
try (HttpSolrClient client = new HttpSolrClient.Builder(url).withConnectionTimeout(10000)
        .withSocketTimeout(60000).build()) {

SimpleSolrResponse response = request.process(client, "demo");
NamedList<Object> resp = response.getResponse();
}
