上一章讲了怎么使用solr admin向solr服务器添加索引，Solr 是一个独立的企业级搜索应用服务器，它对外提供类似于 Web-service 的 API 接口。用户可以通过 http请求，向搜索引擎服务器提交一定格式的 XML 文件，生成索引；也可以通过 Http Get 操作提出查找请求，并得到XML 格式的返回结果。所以我们可以使用httpClient作为客户端向solr服务器添加索引，但是幸运的是，solr为我们提供专门的客户端jar包，solrj，我们可以使用该jar包向solr服务器提交索引。

首先我们导入相关的包，相关的jar包可以通过下载的solr的压缩包中获取，其中包括：

1.dist/solrj-lib

2.dist/solr-solrj-*.jar

把这些jar包导入到classpath中，我们就可以开始使用solrj了。

HttpSolrServer

		String url = "http://localhost:8080/solr";
		HttpSolrServer server = new HttpSolrServer(url);
		server.setMaxRetries(1); // defaults to 0. > 1 not recommended.
		server.setConnectionTimeout(5000); // 5 seconds to establish TCP
		// Setting the XML response parser is only required for cross
		// version compatibility and only when one side is 1.4.1 or
		// earlier and the other side is 3.1 or later.
		server.setParser(new XMLResponseParser()); // binary parser is used by
													// default
		// The following settings are provided here for completeness.
		// They will not normally be required, and should only be used
		// after consulting javadocs to know whether they are truly required.
		server.setSoTimeout(1000); // socket read timeout
		server.setDefaultMaxConnectionsPerHost(100);
		server.setMaxTotalConnections(100);
		server.setFollowRedirects(false); // defaults to false
		// allowCompression defaults to false.
		// Server side must support gzip or deflate for this to have any effect.
		server.setAllowCompression(true);

 // Note that the following property could be set through JVM level arguments too
  System.setProperty("solr.solr.home", "/home/shalinsmangar/work/oss/branch-1.3/example/solr");
  CoreContainer.Initializer initializer = new CoreContainer.Initializer();
  CoreContainer coreContainer = initializer.initialize();
  EmbeddedSolrServer server = new EmbeddedSolrServer(coreContainer, "");

    File home = new File( "/path/to/solr/home" );
    File f = new File( home, "solr.xml" );
    CoreContainer container = new CoreContainer();
    container.load( "/path/to/solr/home", f );

    EmbeddedSolrServer server = new EmbeddedSolrServer( container, "core name as defined in solr.xml" );

		 SolrInputDocument doc1 = new SolrInputDocument();
		 doc1.addField( "id", "333333333333333", 1.0f );
		 doc1.addField( "name", "3333333333333333333", 1.0f );
		 doc1.addField( "price", 10 );
		 server.add(doc1);
		 server.commit();

		SolrQuery solrQuery = new SolrQuery();
		solrQuery.setQuery("q=3333333333333333333");
		QueryResponse queryResponse= server.query(solrQuery);	
		System.out.println(queryResponse.getResults().get(0).getFieldValue("name"));

首先我们需要新建一个java bean。

public class Item {
	
	@Field
    private String id;
    
    @Field
    private String category;

    @Field
    private List<String> features;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getCategory() {
		return category;
	}

	public void setCategory(String category) {
		this.category = category;
	}

	public List<String> getFeatures() {
		return features;
	}
	
	public void setFeatures(List<String> features) {
		this.features = features;
	}
    
}

		Item item = new Item();
		item.setId("201404300001");
		item.setCategory("category");
		item.setFeatures(Arrays.asList("feature1","feature2","feature3"));
		server.addBean(item);
		server.commit();

		SolrQuery solrQuery = new SolrQuery();
		solrQuery.setQuery("q=feature1");
		QueryResponse queryResponse= server.query(solrQuery);	
		List<Item> items = queryResponse.getBeans(Item.class);
		System.out.println(items.get(0).getCategory());

3.跟我学solr---使用solrj添加索引
