SolrJ

Question

我尝试使用 java 将 Solr 5.5.4 与 SolrJ jar 连接，但 Solr 未连接。它有一些错误。

try{
    String urlString = "http://localhost:8983/solr/#/gettingstarted";
    HttpSolrClient solrClient = new HttpSolrClient(urlString);
    QueryResponse queryResponse = solrClient.query(new SolrQuery("*:*"));
    System.out.println(queryResponse.toString());
} catch (SolrServerException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} catch (Exception e) {
    e.printStackTrace();
}

这是 Maven 依赖项：

<dependency>
    <groupId>org.apache.solr</groupId>
    <artifactId>solr-solrj</artifactId>
    <version>5.5.4</version>
</dependency>

获取错误：

org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://localhost:8983/solr/#/gettingstarted: Expected mime type application/octet-stream but got text/html. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

确保我的 solr 运行我在下面附上的屏幕截图，

请帮助我，感谢提前。

Answer 1

尝试指定没有锚 # 的 Url，这应该是正确的方法。

String urlString = "http://localhost:8983/solr/gettingstarted";
HttpSolrClient solrClient = new HttpSolrClient(urlString);

我假设 gettingstarted 是您正在使用的集合的名称。
