JCR研究：jackrabbit

一。使用 svn checkout出jackrabbit的src code
svn co http://svn.apache.org/repos/asf/jackrabbit/trunk jackrabbit
二。進到checkout出來的根目錄，使用 maven 進行build
mvn install
三。完成建置後 maven 會在家目錄產生jackrabbit的jars：
${home}\.maven\repository\org.apache.jackrabbit\jars\jackrabbit-*-SNAPSHOT.jar

四。在classpath引入必要的jars
jcr的有：
jcr-1.0.jar
jackrabbit的有：
jackrabbit-api-1.5-SNAPSHOT.jar
jackrabbit-core-1.5-SNAPSHOT.jar
jackrabbit-jcr-commons-1.5-SNAPSHOT.jar
jackrabbit-spi-1.5-SNAPSHOT.jar
jackrabbit-spi-commons-1.5-SNAPSHOT.jar
jackrabbit-text-extractors-1.5-SNAPSHOT.jar
slf4j的有：
slf4j-api-1.3.0.jar
slf4j-simple-1.5.2.jar
其他：
commons-collections-3.1.jar
concurrent-1.3.4.jar
derby-10.2.1.6.jar
commons-io-1.4.jar
lucene-core-2.2.0.jar
PDFBox-0.7.3.jar
poi-3.0.2-FINAL-20080204.jar
tm-extractors-0.4.jar
poi-scratchpad-3.0.2-FINAL-20080204.jar
poi-contrib-3.0.2-FINAL-20080204.jar

五。第一個登入程式FirstHop
public static void main(String[] args) throws Exception {
// local repository
// System.setProperty("org.apache.jackrabbit.repository.home", "D:/jackrabbit-repos");
// Repository repository = new TransientRepository();
// http rmi repository
Repository repository = new URLRemoteRepository("http://192.168.1.57:-1/jackrabbit-webapp-1.5-SNAPSHOT/rmi");
// rmi repository
// Repository repository = new RMIRemoteRepository("//localhost/jackrabbit.repository");
Session session = repository.login(new SimpleCredentials("transtep", "".toCharArray()));
try {
String user = session.getUserID();
String name = repository.getDescriptor(Repository.REP_NAME_DESC);
System.out.println("Logged in as " + user + " to a " + name + " repository.");
Workspace workspace = session.getWorkspace();
Node rootNode = session.getRootNode();
// // 儲存資料
workspace.getNamespaceRegistry().registerNamespace("xsignage", "http://www.transtep.com/xsignage/1.0");
Node imageNode = rootNode.addNode("xsignage:image");
imageNode.setProperty("xsignage:type", "圖片");
imageNode.setProperty("xsignage:read", true);
imageNode.setProperty("xsignage:write", true);
Node jpegImage = imageNode.addNode("xsignage:jpeg");
jpegImage.setProperty("xsignage:yuffie", new FileInputStream(new File("./尤菲.jpg")));
session.save();
// 取出資料
Node imageNode2 = rootNode.getNode("xsignage:image");
System.out.println("type: " + imageNode2.getProperty("xsignage:type").getString());
System.out.println("read: " + imageNode2.getProperty("xsignage:read").getString());
System.out.println("write: " + imageNode2.getProperty("xsignage:write").getString());
Node jpegImage2 = imageNode2.getNode("xsignage:jpeg");
InputStream ins = jpegImage2.getProperty("xsignage:yuffie").getStream();
FileOutputStream pos = new FileOutputStream("./yuffie.jpg");
int read = -1;
while ((read = ins.read()) != -1) {
pos.write(read);
}
} finally {
session.logout();
}
}
