java LDAP 使用简单步骤

项目背景：
某电信项目，使用LDAP存储用户信息。现在需要根据用户的“电话号码”获取其全部信息。
关键代码(我当时不会的)：

[size=large][color=green]
// LDAPEntry nextEntry = searchResults.next();
// LDAPAttributeSet attSet = nextEntry.getAttributeSet();
// for (Iterator iterator = attSet.iterator(); iterator.hasNext();) {
//	LDAPAttribute att = (LDAPAttribute) iterator.next();
//	LDAPattrNameValue.add(att.getName() + ": " + att.getStringValue());
//}
[/color][/size]

详细代码：

// ConnectDIR
String ldapHost = "xxx.xxx.xxx.xxx";

// To get user's id
String loginDN = "0001";

// To get user's password
String password = "admin"

LDAPConnection lc = new LDAPConnection();

// connect the "LDAP Server"
lc.connect(ldapHost, LDAPConnection.DEFAULT_PORT);

// Binding "LDAP Server"
lc.bind(LDAPConnection.LDAP_V3, loginDN, password.getBytes("UTF8"));

//SearchBase、SearchFilter、SearchScope
String strSearchBase = CLdapBasednInfo.getBaseDnNe();
String strsearchFilter = "cn=" + telephoneNO.replaceFirst("0{1}", "");
int intSearchScope = LDAPConnection.SCOPE_SUB;

// search the LDAP BY the telephoneNO TO get ENTRY. 
LDAPSearchResults searchResults = lc.search(strSearchBase,intSearchScope,strsearchFilter,null,false);

// searchResults.hasMore()

while (searchResults.hasMore()) {
	LDAPEntry nextEntry = null;
	try {
		nextEntry = searchResults.next();
	} catch (LDAPException ldape) {
		throw ldape;
	}
	dn = nextEntry.getDN();
	
	LDAPattrNameValue.add("dn:" + dn);
	LDAPAttributeSet attSet = nextEntry.getAttributeSet();
	for (Iterator iterator = attSet.iterator(); iterator.hasNext();) {
		LDAPAttribute att = (LDAPAttribute) iterator.next();
		LDAPattrNameValue.add(att.getName() + ": " + att.getStringValue());
	}
	
}

lc.disconnect();

// catch(LDAPException ldape)

// ===
// LDAPEntry nextEntry = searchResults.next();
// LDAPAttributeSet attSet = nextEntry.getAttributeSet();
// for (Iterator iterator = attSet.iterator(); iterator.hasNext();) {
//	LDAPAttribute att = (LDAPAttribute) iterator.next();
//	LDAPattrNameValue.add(att.getName() + ": " + att.getStringValue());
//}
