ldap分页排序

1、com.sun.jndi.ldap.ctl.VirtualListViewControl vlv分页
需要 sun-jndi-ldapbp.jar

public static void pageAndSort(){
		Hashtable env = new Hashtable();
		env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
		env.put(Context.PROVIDER_URL, "ldap://10.16.15.36:389");
		env.put(Context.SECURITY_AUTHENTICATION, "simple");
		env.put(Context.SECURITY_PRINCIPAL, "uid=yuyong,ou=applications,o=peter.com.cn,o=yy");
		env.put(Context.SECURITY_CREDENTIALS, "java");
		LdapContext ctx = null;
		try {
			ctx = new InitialLdapContext(env, null);
                        //排序字段
			String sortkey="uid";
			int beforeCount=0;
			int afterCount=0;
			int nTargetOffset=2;
                        int nPageSize=10;
			VirtualListViewControl vctl = new VirtualListViewControl(nTargetOffset,beforeCount,afterCount,nPageSize,Control.CRITICAL);;
			ctx.setRequestControls(new Control[]{new SortControl(sortkey,Control.CRITICAL),vctl});
			String retAtt[]={"uid"};
			SearchControls constraints=new SearchControls();
			constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
			constraints.setReturningAttributes(retAtt);
			NamingEnumeration results=ctx.search("ou=People,o=peter.com.cn,o=yy", "(code=30003357)",constraints);
			while(results!=null&&results.hasMore()){
				SearchResult entry = (SearchResult)results.next();
				System.out.println(entry.getAttributes());
			}
			ctx.close();
		} catch (NamingException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

2、netscape ldap分页排序
需要下载 ldapsdk.jar

public static void pageAndSort2(){
		String HOST="10.16.15.36";
		int PORT = 389;
		int MIN_CONN_SIZE=1;
		int MAX_CONN_SIZE=5;
		String USER_ID="uid=yuyong,ou=applications,o=peter.com.cn,o=yy";
		String PASSWORD="java";
		ConnectionPool connPool;
		try{
			connPool=new ConnectionPool(MIN_CONN_SIZE,MAX_CONN_SIZE,HOST,PORT);
			LDAPConnection conn=connPool.getConnection();
			conn.authenticate(USER_ID, PASSWORD);
			String []attrs={"uid"};
			LDAPSearchResults res=conn.search("ou=People,o=peter.com.cn,o=yy", LDAPConnection.SCOPE_SUB, "code=30003357", attrs, false);
			LDAPCompareAttrNames compareAttrNames = new LDAPCompareAttrNames("uid",true);
			res.sort(compareAttrNames);
			while(res.hasMoreElements()){
				try{
					LDAPEntry entry=res.next();
					System.out.println(entry.getAttribute("uid").getStringValues().nextElement());
				}catch(Exception e){
					e.printStackTrace();
				}
			}
			connPool.close(conn); 
		}catch(Exception e){
			e.printStackTrace();
		}
		
	}

这个不是不是开源的吧，我是用unboundid for java 操作openldap的，想实现对查询结果集的培训，
