这篇博客展示了如何使用Java结合Novell的API进行LDAP操作，包括建立连接、增加记录、删除记录、更新记录和查询记录。示例代码详细解释了每个步骤，适合初学者了解和实践。

Ldap
采用的是novell 的API。
参考代码如下：
创建连接LDAP的类：Ldap_Connection
package ldap1;

import com.novell.ldap.LDAPConnection;
import com.novell.ldap.LDAPException;

public class Ldap_Connection {
@SuppressWarnings("deprecation")
public static LDAPConnection getLdapConnection(){
LDAPConnection lc = new LDAPConnection();
        try {
            lc.connect("172.16.2.18",389);               lc.bind(LDAPConnection.LDAP_V3,"cn=li,ou=People,dc=gsoft,dc=com","newpassword");
            System.out.println("连接成功！");
            return lc ;
        } catch (LDAPException e) {
            System.err.print("连接异常！   ");
            e.printStackTrace();
        }
return null;
}
}
创建添加类：Ldap_Add
package ldap1;

import com.novell.ldap.LDAPAttribute;
import com.novell.ldap.LDAPAttributeSet;
import com.novell.ldap.LDAPConnection;
import com.novell.ldap.LDAPEntry;
import com.novell.ldap.LDAPException;

public class Ldap_Add {
public static void LDAP_add(LDAPConnection ldapConnection) throws LDAPException{
LDAPAttributeSet attributeSet = new LDAPAttributeSet();
        attributeSet.add(new LDAPAttribute("objectclass", new String(
                "inetOrgPerson")));
        attributeSet.add(new LDAPAttribute("cn", new String[] { "li",
                "Jim Smith", "Jimmy Smith" }));
        attributeSet.add(new LDAPAttribute("givenname", new String[] { "测试",
                "Jim", "Jimmy" }));
        attributeSet.add(new LDAPAttribute("sn", new String("Smith")));
        attributeSet.add(new LDAPAttribute("telephonenumber", new String(
                "1 801 555 1212")));
        attributeSet.add(new LDAPAttribute("mail",
                new String("509357671@qq.com")));
        attributeSet.add(new LDAPAttribute("userpassword", new String(
                "newpassword")));
        LDAPEntry entry = new LDAPEntry("cn=li,ou=People,dc=gsoft,dc=com",
                attributeSet);
        ldapConnection.add(entry);
        System.out.println("成功的添加了一条记录！");
        ldapConnection.disconnect();
}
}

创建删除类：Ldap_Delete
package ldap1;

import com.novell.ldap.LDAPConnection;
import com.novell.ldap.LDAPException;

public class Ldap_Delete {
public static void LDAP_Delete(LDAPConnection lc) throws LDAPException{
LDAPConnection lConnection = Ldap_Connection.getLdapConnection() ;
lConnection.delete("cn=李,ou=People,dc=gsoft,dc=com") ;
lConnection.disconnect() ;
System.out.println("删除一条记录");
}
}

创建查询类：Ldap_Seach
package ldap1;

import java.util.Iterator;
import com.novell.ldap.LDAPAttribute;
import com.novell.ldap.LDAPConnection;
import com.novell.ldap.LDAPEntry;
import com.novell.ldap.LDAPException;
import com.novell.ldap.LDAPSearchResults;
/**
* LDAPConnection.SCOPE_ONE // 只查找基节点第一层的子节点
* LDAPConnection.SCOPE_BASE // 只查找基节点
* LDAPConnection.SCOPE_SUB // 查找基节点下面的所有子节点
**/

public class Ldap_Search {
public static void LDAP_Search(LDAPConnection lc) throws LDAPException{
LDAPSearchResults rs = lc.search("dc=gsoft,dc=com",LDAPConnection.SCOPE_SUB,"objectClass=*",null,false);
int count = 0;
         while(rs.hasMore()){
             LDAPEntry entry = rs.next();
             System.out.println(entry.getDN());
             count++;
         }
         lc.disconnect() ;
         System.out.println("共有"+count+"条记录。");
         lc.disconnect();
}
/**
* 遍历该用户下的所有属性和属性值
* **/
public static void Ldap_Search2(LDAPConnection lc) throws LDAPException{

LDAPSearchResults rs = lc.search("cn=li,ou=People,dc=gsoft,dc=com",LDAPConnection.SCOPE_SUB,"objectClass=*",null,false);
int count = 0;
Iterator iterator = null ;
LDAPEntry entry ;
        while(rs.hasMore()){
             entry = rs.next();
//            System.out.println(entry.getDN());
           LDAPAttributeSet lAttributeSet = entry.getAttributeSet();
            iterator = (Iterator) lAttributeSet.iterator();
            while(iterator.hasNext()){
            LDAPAttribute Attribute =(LDAPAttribute) iterator.next() ;
            System.out.println("name="+Attribute.getName());
            System.out.println("vale="+Attribute.getStringValue());
            count++;
            }

        }
        lc.disconnect() ;
        System.out.println("共有"+count+"条记录。");
        lc.disconnect();
}
}

创建修改类：Ldap_Search
package ldap1;

import java.util.ArrayList;

import com.novell.ldap.LDAPAttribute;
import com.novell.ldap.LDAPConnection;
import com.novell.ldap.LDAPException;
import com.novell.ldap.LDAPModification;

public class Ldap_Update {
public static void LDAP_Upate(LDAPConnection lc) throws LDAPException{
ArrayList<LDAPModification> modList = new ArrayList<LDAPModification>();
LDAPAttribute attribute = new LDAPAttribute("mail", "JSmith@yyn.com");
modList.add(new LDAPModification(LDAPModification.REPLACE, attribute));
//       attribute = new LDAPAttribute("givenName","修改") ;
//       modList.add(new LDAPModification(LDAPModification.ADD, attribute));
       // 这里 LDAPModification 对象有几种方式 LDAPModification.ADD、LDAPModification.DELETE、LDAPModification.REPLACE
//        用list填充 LDAPModification 对象
      LDAPModification[] modsadd = new LDAPModification[modList.size()];
       modsadd = (LDAPModification[]) modList.toArray(modsadd);
//        通过 LDAP连接就行修改操作
      String dn = "cn=li,ou=People,dc=gsoft,dc=com" ;
       lc.modify(dn, modsadd);
       lc.disconnect() ;
}
}
创建测试类：Ldap_Main
package ldap1.main;

import ldap1.Ldap_Add;
import ldap1.Ldap_Connection;
import ldap1.Ldap_Delete;
import ldap1.Ldap_Search;
import ldap1.Ldap_Update;

import com.novell.ldap.LDAPConnection;

public class Ldap_Main {
public static void main(String[] args) {
LDAPConnection ldapConnection = Ldap_Connection.getLdapConnection() ;
try {
Ldap_Delete.LDAP_Delete(ldapConnection);
Ldap_Add.LDAP_add(ldapConnection) ;
Ldap_Search.LDAP_Search(ldapConnection) ;
Ldap_Update.LDAP_Upate(ldapConnection) ;
} catch (Exception e) {
e.printStackTrace();
}

}
}

以上几个简单的功能，能够完成对Ldap的连接，添加、删除、更新、查询的简单操作。
