solr6.1-----solrJ 程序管理索引库

　　solrJ 是solr 提供的一个客户端，就是一个jar 包，把jar 添加到工程中整合solr 服务。

　　所需jar 包

　　D:\solr-6.1.0\dist 下面的 solr-solrj-6.1.0.jar，以及其依赖 D:\solr-6.1.0\dist\solrj-lib 文件夹下面的所有jar

　　

　　创建工程添加jar 包

　　添加 solr 库索引

	@Test
	public void create() throws Exception{
		System.out.println("======================create===============");
		@SuppressWarnings({ "resource", "deprecation" })
		SolrClient solrClient = new HttpSolrClient("http://127.0.0.1:9090/solr/collection1");
		List<SolrInputDocument> docList = new ArrayList<SolrInputDocument>();
		String[] titles = {
				"chihirotj",
                "chihirotj",
                "CAS latency",
                "CAS latency",
                "CAS latency",
                "CAS latency chihirotj"};
		String[] contents = {
				"chihirotj this a vear popular book",
                "chihirotj i love you dlp",
                "CAS latency a a a a a a a",
                "CAS latency you ara bearuiflu",
                "CAS latency i love this computer",
                "CAS latency hao are you"};
		int i = 100;
        for(int j = 0; j <= 5; j ++){
            SolrInputDocument doc = new SolrInputDocument();
            doc.addField("id",i++);
            //需要在core1/conf/managed-schema中有对应的field
            //在solr 6.1 版本中已经不需要了，会自己动态的创建域，类型为strings
            doc.addField("title", titles[j]);
            doc.addField("content", contents[j]);
            docList.add(doc);
        }
        UpdateResponse rsp = solrClient.add(docList);
        System.out.println("Add doc size" + docList.size() + " result:" + rsp.getStatus() + " Qtime:" + rsp.getQTime());
        UpdateResponse rspcommit = solrClient.commit();
        System.out.println("commit doc to index" + " result:" + rsp.getStatus() + " Qtime:" + rspcommit.getQTime());
	}

　　

　　之后在 管理员页面查询数据：点击query 能够查询出，刚刚添加的数据，则添加数据成功。

　　

　　默认添加的域为 strings 类型。我们需要修改类型，使用能够解析字符串的分词器（title  域lz已经做了修改）

　　查询 solr 索引库

	@Test
    public void query(){
		System.out.println("======================query===================");
    	SolrClient solrClient = new HttpSolrClient("http://127.0.0.1:9090/solr/collection1");
        SolrQuery query = new SolrQuery();
        //查询条件
        query.setQuery("chihirotj");
        //高亮字段
        query.setParam("hl.fl", "title");
        //开启高亮
        query.setHighlight(true);
        //返回的字符个数
        query.setHighlightFragsize(200);
        //是否需要完全匹配
        //query.setHighlightRequireFieldMatch(true);
        //前缀
        query.setHighlightSimplePre("<em>");
        //后缀
        query.setHighlightSimplePost("</em>");
        QueryResponse response = null;
        try {
            response = solrClient.query(query);
            System.out.println(response.toString());
            System.out.println();
            SolrDocumentList docs = response.getResults();
            Map<String, Map<String, List<String>>>  maps = response.getHighlighting();
            System.out.println("文档个数：" + docs.getNumFound());
            System.out.println("查询时间：" + response.getQTime());
            for (SolrDocument doc : docs) {
            	//配置分词后
                System.out.println("id: " + doc.getFieldValue("id") + " title: " + doc.getFieldValue("title"));
            }
            for (Map<String, List<String>> map : maps.values()) {
            	List<String> title = map.get("title");
            	//高量的值
				System.out.println(title.iterator().next());
			}
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

　　

　　　　运行结果：

　　 　　

　　删除 索引库

　　

　　 @Test
    public void deleteById() {
        System.out.println("======================deleteById ===================");
        SolrClient solrClient = new HttpSolrClient("http://127.0.0.1:9090/solr/collection1");
        try {
    		String[] ids = {"1", "2", "4"};
    		for (String id : ids) {
    			UpdateResponse rsp = solrClient.deleteById(id);
    			System.out.println("delete id:" + id + " result:" + rsp.getStatus() + " Qtime:" + rsp.getQTime());
			}
    		solrClient.commit();
        } catch (SolrServerException | IOException e) {
            e.printStackTrace();
        }
    }
