如何在SolrJ中设置查询中的集合

Question

client.query("collectionName", query);

但是，在我看来，SolrJ忽略了收集，因为我得到了以下错误：

/solr/update The requested resource is not available.

当我在SolrClient URL中而不是在查询函数中添加集合时，它工作得很好。这个解决方案阻碍了我使用单个客户端请求多个集合，所以我想使用第一个。有人遇到过吗？

编辑：我也检查了6.6。还是老样子。完全错误：

消息/Solr/Update

描述请求的资源不可用。

嗯，这真的很奇怪--刚刚在我的测试环境中的DSE 6.0.2上测试过--对于我的表（使用标准SolrJ客户端6.6.0):

<dependency>
  <groupId>org.apache.solr</groupId>
  <artifactId>solr-solrj</artifactId>
  <version>6.6.0</version>
</dependency>

代码：

public static void main(String[] args) throws SolrServerException, IOException {
    String url = "http://192.168.0.10:8983/solr";

    SolrClient client = new HttpSolrClient.Builder(url).build();
    SolrQuery query = new SolrQuery();
    query.setQuery("*:*");
    query.addFilterQuery("user:\"krystina.morissette\"");
    query.setRows(10);
    QueryResponse response = client.query("gatling.user_tokens", query);
    SolrDocumentList list = response.getResults();
    System.out.println("Num found=" + list.getNumFound());
    for (SolrDocument doc: list) {
        System.out.println(doc);
    }
}

给我以下信息：

Num found=4
