基本信息：

版本：7.0.0

单机版，cloud版本有所区分

步骤：

1.依赖:

    	
     
      org.apache.solr
     	
     
      solr-solrj
     	
     
      7.0.0
     
    

2.业务封装代码：

public class SearchClient {	private SolrClient client;	public SearchClient(String baseSolrUrl, String core) {		client = new HttpSolrClient.Builder(baseSolrUrl + core).build();	}	 	public List
    
      search(String kw,  int rows)			throws Exception {		SolrQuery query = new SolrQuery();		query.setQuery("title:" + kw);		query.setQuery("type:" + kw);		query.setQuery("content:" + kw);		query.setRows(rows);		QueryResponse queryResponse = client.query(query);		SolrDocumentList results = queryResponse.getResults();		List
     
       items =new ArrayList
      
       ();		  for (SolrDocument solrDocument : results) {			  Article item=new Article();			  item.setId(solrDocument.get("id")+"");			  item.setTitle(solrDocument.get("title")+"");			  item.setType(solrDocument.get("type")+"");			  items.add(item);		}				return items;	}	public void delete(String id) throws Exception {		client.deleteById(id);		client.commit();	}	public void add(List
       
         items) throws Exception {		for (Article item : items) {			SolrInputDocument solrInputDocument = new SolrInputDocument();			solrInputDocument.addField("id", item.getId());			solrInputDocument.addField("content", item.getContent());			solrInputDocument.addField("title", item.getTitle());			solrInputDocument.addField("type", item.getType());			client.add(solrInputDocument);		}				client.commit();	}	public void closeQuietly() {		try {			client.close();		} catch (IOException e) {			e.printStackTrace();		}	}}
       
      
     
    

测试：

public static void add() throws Exception {	String baseSolrUrl="http://localhost:8983/solr/";	String core="someabcd";	SearchClient client=new SearchClient(baseSolrUrl,core);	List
    
      items=new ArrayList
     
      ();	List
      
        lines=FileUtils.readLines(new File("E:/data/test.data00"));	for (String line : lines) {		Article item=JSON.parseObject(line, Article.class);		item.setId(CommonUtils.getUUID32());		items.add(item);	}	client.add(items);	client.closeQuietly();}public static void search() throws Exception {	String baseSolrUrl="http://localhost:8983/solr/";	String core="someabcd";		SearchClient client=new SearchClient(baseSolrUrl,core);	List
       
         items=client.search("Apache版本", 10);	System.out.println(items);	client.closeQuietly();}public static void del(String id) throws Exception {	String baseSolrUrl="http://localhost:8983/solr/";	String core="someabcd";		SearchClient client=new SearchClient(baseSolrUrl,core);	client.delete(id);	client.closeQuietly();}
       
      
     
    

ps：

如果想直接反序列为Bean那么需要用其自定义注解

@Field("id")

private String id;

@Field

private String title;
