Export and import apacheds to LDIF programmatically from java

Question

I created a server in Apache Directory Studio. I also created a section and pasted some entries into this Java server form. Now I want to backup and restore this data in an LDIF file and programmatically. I am new to LDAP. So please show me a detailed way to export and import records programmatically using java from my server in LDIF.

Current solution:

Now I use this approach for backup:

EntryCursor cursor = connection.search(new Dn("o=partition"), "(ObjectClass=*)", SearchScope.SUBTREE, "*", "+"); Charset charset = Charset.forName("UTF-8"); Path filePath = Paths.get("src/main/resources", "backup.ldif"); BufferedWriter writer = Files.newBufferedWriter(filePath, charset); String st = ""; while (cursor.next()) { Entry entry = cursor.get(); String ss = LdifUtils.convertToLdif(entry); st += ss + "\n"; } writer.write(st); writer.close(); 

For recovery, I use this:

  InputStream is = new FileInputStream(filepath); LdifReader entries = new LdifReader(is); for (LdifEntry ldifEntry : entries) { Entry entry = ldifEntry.getEntry(); AddRequest addRequest = new AddRequestImpl(); addRequest.setEntry(entry); addRequest.addControl(new ManageDsaITImpl()); AddResponse res = connection.add(addRequest); } 

But I'm not sure if this is correct.

The problem with this solution is:

When I back up my database, it writes entries to LDIF randomly, so the restore does not work until I fix the order of the entries manually. Am I the best way there? Please help me.

Answer 1

After a long search, I really understand that a record recovery solution is a simple recursion. The backup procedure does not randomly print records; it maintains the order of trees. In this way, simple recursion can organize records well. Here is an example of the code I use -

 void findEntry(LdapConnection connection, Entry entry, StringBuilder sb) throws LdapException, CursorException { sb.append(LdifUtils.convertToLdif(entry)); sb.append("\n"); EntryCursor cursor = connection.search(entry.getDn(), "(ObjectClass=*)", SearchScope.ONELEVEL, "*", "+"); while (cursor.next()) { findEntry(connection, cursor.get(), sb); } }

Well, you marked it as Java and therefore see the UnboundID LDAP SDK or, as you use APacheDS, why not look at the Apache LDAP API

Any of them will work. I am currently using the [UnboundID LDAP SDK], which have [LDIF-specific APIs]. 3 . I assume that [Apache LDAP API API] as well, but I have not used them.
