Xindice编程介绍

Xindice是用来保存xml数据，类似与一个xml数据库。

在myeclipse，tomcat中配置xindice

 

1. 下载xml-xindice-1.2m1-bin.zip。

2. 在Myeclipse中建立web项目，并把所有xml-xindice-1.2m1-bin.zip解压后的jar包导入到lib文件夹下。

3. 在Myeclipse中部署tomcat服务器。

4. 运行tomcat服务器。

5. 输入http://localhost:8080/xindice/检测xindice是否配置好。

xindice编程

创建集合

package org.apache.xindice.examples; import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*; import org.apache.xindice.client.xmldb.services.*; import org.apache.xindice.xml.dom.*; public class CreateCollection { public static void main(String[] args) throws Exception{ Collection col = null; try{ String driven = "org.apache.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driven); Database database = (Database) c.newInstance(); DatabaseManager.registerDatabase(database); String uri = "xmldb:xindice://localhost:8080/db/"; col = DatabaseManager.getCollection(uri); String collectionName = "mycollection"; CollectionManager service = (CollectionManager) col.getService("CollectionManager","1.0"); String collectionConfig = "<collection compressed = /"true/" "+ " name = /""+collectionName + "/">"+ " <filer class=/"org.apache.xindice.core.filer.BTreeFiler/"/>"+ "</collection>"; service.createCollection(collectionName, DOMParser.toDocument(collectionConfig)); System.out.println("collection "+collectionName+" created."); } catch (XMLDBException e){ System.err.println("XML:DB Exception occured "+e.errorCode); } finally{ if(col !=null) { col.close(); } } } } 在数据库中增加xml文档

package org.apache.xindice.examples; import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*; import java.io.*; public class AddDocument { public static void main(String[] args) throws Exception { Collection col = null; try { String driven = "org.apache.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driven); Database database = (Database) c.newInstance(); DatabaseManager.registerDatabase(database); col = DatabaseManager .getCollection("xmldb:xindice://localhost:8080/db/mycollection"); String data = readFileFromDisk("C:/xml/test.xml"); XMLResource document = (XMLResource) col.createResource(null, "XMLResource"); document.setContent(data); col.storeResource(document); System.out.println("Document " + "test.xml" + " inserted"); } catch (XMLDBException e) { System.out.println("XML:DB Exception occured " + e.errorCode); } finally { if (col != null) { col.close(); } } } public static String readFileFromDisk(String fileName) throws Exception { File file = new File(fileName); FileInputStream insr = new FileInputStream(file); byte[] fileBuffer = new byte[(int) file.length()]; insr.read(fileBuffer); insr.close(); return new String(fileBuffer); } } 获取检测文档

package org.apache.xindice.examples; import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*; public class RetrieveDocument { public static void main(String[] args) throws Exception { Collection col = null; try { String driven = "org.apache.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driven); Database database = (Database) c.newInstance(); DatabaseManager.registerDatabase(database); col = DatabaseManager .getCollection("xmldb:xindice://localhost:8080/db/mycollection"); XMLResource document = (XMLResource) col .getResource("0927ed220364332c0000011dfc70fda0"); if (document != null) { System.out.println(document.getContent()); } else { System.out.println("Document not found"); } } catch (XMLDBException e) { System.err.println("XML:DB Exception occured " + e.errorCode); } finally { if (col != null) { col.close(); } } } } 删除文档

package org.apache.xindice.examples; import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*; import java.io.*; public class DeleteDocument { public static void main(String[] args) throws Exception{ Collection col = null; try { String driven = "org.apache.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driven); Database database = (Database) c.newInstance(); DatabaseManager.registerDatabase(database); col = DatabaseManager .getCollection("xmldb:xindice://localhost:8080/db/mycollection"); Resource document = col.getResource("0927ed220364332c0000011dfc70fda0"); col.removeResource(document); System.out.println("Document " + "test.xml" + " removed"); } catch (XMLDBException e) { System.out.println("XML:DB Exception occured " + e.errorCode); } finally { if (col != null) { col.close(); } } } } 查找文档中内容

package org.apache.xindice.examples; import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*; public class Example1 { public static void main(String[] args) throws Exception { Collection col = null; try { String driver = "org.apache.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driver); Database database = (Database) c.newInstance(); DatabaseManager.registerDatabase(database); String uri = "xmldb:xindice://localhost:8080/db/mycollection"; col = DatabaseManager.getCollection(uri); String xpath = "//person[fname='John']"; XPathQueryService service = (XPathQueryService) col.getService( "XPathQueryService", "1.0"); ResourceSet resultSet = service.query(xpath); ResourceIterator results = resultSet.getIterator(); while (results.hasMoreResources()) { Resource res = results.nextResource(); System.out.println((String) res.getContent()); } } catch (XMLDBException e) { System.err.println(e); } finally { if (col != null) { col.close(); } } } } 修改文档

package org.apache.xindice.examples; import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*; public class XUpdate { public static void main(String[] args) throws Exception{ Collection col = null; try { String driven = "org.apache.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driven); Database database = (Database) c.newInstance(); DatabaseManager.registerDatabase(database); col = DatabaseManager .getCollection("xmldb:xindice://localhost:8080/db/mycollection"); String xupdate = "<xu:modifications version=/"1.0/""+ " xmlns:xu=/"http://www.xmldb.org/xupdate/">"+ " <xu:remove select=/"/person/phone[@type = 'home']/"/>"+ " <xu:update select=/"/person/phone[@type = 'work']/">"+ " 480-300-3003"+ " </xu:update>"+ "</xu:modifications>"; XUpdateQueryService service = (XUpdateQueryService) col.getService("XUpdateQueryService", "1.0"); service.update(xupdate); } catch (XMLDBException e) { System.err.println("XML:DB Exception occured " + e.errorCode); } finally { if (col != null) { col.close(); } } } }
