指尖上的电商---(4).net开发solr
这一节我们看下如何把查询数据放到server端存储，这里我们须要使用client工具来操作与服务端数据打交道，网上有好多基于.NET开发的SOLRclient，我们这里选择easynet.solr，非常方便的一个DLL,
下载地址:http://easynet.codeplex.com/SourceControl/latest
这一节主要包含Solr数据索引的加入，改动，删除，查询等简单功能。
我们先来看下效果图
1.创建对象
public class Product
{ /// <summary>
/// 产品编码
/// </summary>
public string ProductCode { get; set; } /// <summary>
/// 产品名称
/// </summary>
public string ProductName { get; set; }
}
2.配置schema.xml
找到tomcat下的schema.xml配置文件 。详细位置:C:\Program Files\Apache Software Foundation\Tomcat 8.0\solr\collection1\conf
加入字段节点，这里我们设置ProductCode为主键，注意设置
<uniqueKey>ProductCode</uniqueKey>

<!-- Kuromoji Japanese morphological analyzer/tokenizer (JapaneseTokenizer) Kuromoji has a search mode (default) that does segmentation useful for search. A heuristic
is used to segment compounds into its parts and the compound itself is kept as synonym. Valid values for attribute mode are:
normal: regular segmentation
search: segmentation useful for search with synonyms compounds (default)
extended: same as search mode, but unigrams unknown words (experimental) For some applications it might be good to use search mode for indexing and normal mode for
queries to reduce recall and prevent parts of compounds from being matched and highlighted.
Use <analyzer type="index"> and <analyzer type="query"> for this and mode normal in query. Kuromoji also has a convenient user dictionary feature that allows overriding the statistical
model with your own entries for segmentation, part-of-speech tags and readings without a need
to specify weights. Notice that user dictionaries have not been subject to extensive testing. User dictionary attributes are:
userDictionary: user dictionary filename
userDictionaryEncoding: user dictionary encoding (default is UTF-8) See lang/userdict_ja.txt for a sample user dictionary file. Punctuation characters are discarded by default. Use discardPunctuation="false" to keep them. See http://wiki.apache.org/solr/JapaneseLanguageSupport for more on Japanese language support.

3.创建序列化器
public class Product
{ /// <summary>
/// 产品编码
/// </summary>
public string ProductCode { get; set; } /// <summary>
/// 产品名称
/// </summary>
public string ProductName { get; set; }
} /// <summary>
/// 反序列化器
/// </summary>
class ProductDeserializer : IObjectDeserializer<Product>
{
public IEnumerable<Product> Deserialize(SolrDocumentList result)
{
foreach (SolrDocument doc in result)
{
yield return new Product()
{
ProductCode = doc["ProductCode"].ToString(),
ProductName = doc["ProductName"].ToString() };
}
}
}
4.查询数据
static OptimizeOptions optimizeOptions = new OptimizeOptions();
static ISolrResponseParser<NamedList, ResponseHeader> binaryResponseHeaderParser = new BinaryResponseHeaderParser();
static IUpdateParametersConvert<NamedList> updateParametersConvert = new BinaryUpdateParametersConvert();
static ISolrUpdateConnection<NamedList, NamedList> solrUpdateConnection = new SolrUpdateConnection<NamedList, NamedList>() { ServerUrl = "http://localhost:8040/Solr/" };
static ISolrUpdateOperations<NamedList> updateOperations = new SolrUpdateOperations<NamedList, NamedList>(solrUpdateConnection, updateParametersConvert) { ResponseWriter = "javabin" }; static ISolrQueryConnection<NamedList> connection = new SolrQueryConnection<NamedList>() { ServerUrl = "http://localhost:8040/Solr/" };
static ISolrQueryOperations<NamedList> operations = new SolrQueryOperations<NamedList>(connection) { ResponseWriter = "javabin" }; static IObjectDeserializer<Product> exampleDeserializer = new ProductDeserializer();
static ISolrResponseParser<NamedList, QueryResults<Product>> binaryQueryResultsParser = new BinaryQueryResultsParser<Product>(exampleDeserializer); public void Query()
{
//查询
var result = operations.Query("collection1", "/select", SolrQuery.All, null);
var header = binaryResponseHeaderParser.Parse(result);
var examples = binaryQueryResultsParser.Parse(result);
this.dataGridView1.DataSource = examples.ToList();
}
private void button2_Click(object sender, EventArgs e)
{
Query(); }
5.加入索引数据
private void button1_Click(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(textBox1.Text)||string.IsNullOrWhiteSpace(textBox2.Text))
{
MessageBox.Show("编码和名称不能为空");
return;
} var docs = new List<SolrInputDocument>();
var doc = new SolrInputDocument();
doc.Add("ProductCode", new SolrInputField("ProductCode",textBox1.Text));
doc.Add("ProductName", new SolrInputField("ProductName",textBox2.Text));
docs.Add(doc);
var result = updateOperations.Update("collection1", "/update", new UpdateOptions() { OptimizeOptions = optimizeOptions, Docs = docs });
var header = binaryResponseHeaderParser.Parse(result); this.DialogResult = DialogResult.OK;
}
6.删除索引数据
private void button3_Click(object sender, EventArgs e)
{
//删除
if (this.dataGridView1.SelectedRows.Count != 1)
{
return;
} string code = this.dataGridView1.SelectedRows[0].Cells[0].Value.ToString();
var result = updateOperations.Update("collection1", "/update", new UpdateOptions() { OptimizeOptions = optimizeOptions, DelById = new string[] { code } });
var header = binaryResponseHeaderParser.Parse(result); System.Console.WriteLine(string.Format("Update Status:{0} QTime:{1}", header.Status, header.QTime));
System.Console.ReadLine();
Query();
