2、GetFile.java
package com.neohope.existdb.test; import org.exist.storage.serializers.EXistOutputKeys; import org.exist.xmldb.EXistResource; import org.xmldb.api.DatabaseManager; import org.xmldb.api.base.Collection; import org.xmldb.api.base.Database; import org.xmldb.api.modules.XMLResource; import javax.xml.transform.OutputKeys; public class GetFile extends Base{ public static void GetXML(String collectionName,String documentId, String user, String pwd) throws Exception { if(cl==null)throw(new ClassNotFoundException(driver)); Database database = (Database) cl.newInstance(); database.setProperty("ssl-enable", "false"); DatabaseManager.registerDatabase(database); Collection collection = DatabaseManager.getCollection(URI + collectionName,user,pwd); if(collection == null) { System.out.println("collection not found: " + collectionName); } else { collection.setProperty(OutputKeys.INDENT, "yes"); collection.setProperty(EXistOutputKeys.EXPAND_XINCLUDES, "no"); collection.setProperty(EXistOutputKeys.PROCESS_XSL_PI, "yes"); XMLResource res = (XMLResource) collection.getResource(documentId); if (res == null) { System.out.println("document not found: "+ documentId); } else { System.out.println(res.getContent()); System.out.println("Size: " + ((EXistResource) res).getContentLength()); } } } public static void main(String args[]) throws Exception { String user = "neotest"; String pwd = "neotest"; GetXML("/db/ZS_FrontPageBA", "病案首页01.xml",user,pwd); } }
