java操作ldap

使用jndi连接ldap数据库,操作ldap条目

1,连接ldap数据库:

public DirContext createDirContext(String ip,int port,String bindDn,String password){

    Hashtable<String, String> env = new Hashtable<String, String>();
        env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldap://" + ip + ":" + port);
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, bindDn);
        env.put(Context.SECURITY_CREDENTIALS, password);
    DirContext ctx = null;
    try{

        ctx = new InitialDirContext(env);
    }catch(new InitialDirContext(env);){

         e.printStackTrace();
    }
    return ctx;
}
        

能否成功创建DirContext对象可以用来测试绑定用户密码是否正确,在进行ldap登陆测试时使用。

2,创建条目

public void addItem(String ip,int port,String bindDN, String password, String itemDn, HashMap<String, ArrayList<String>> attrValueMap)
            throws NamingException {
        Hashtable<String, String> env = new Hashtable<String, String>();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldap://" + ip + ":" + port);
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, bindDN);
        env.put(Context.SECURITY_CREDENTIALS, password);
     DirContext ctx = null;
try { ctx = new InitialDirContext(env); BasicAttributes entry = new BasicAttributes(true); Iterator<String> defaultAttrValueMapKeyIt = attrValueMap.keySet().iterator(); while (defaultAttrValueMapKeyIt.hasNext()) { String attr = defaultAttrValueMapKeyIt.next(); ArrayList<String> valueList = attrValueMap.get(attr); if (1 == valueList.size()) { entry.put(attr, valueList.get(0)); } else { Attribute attribute = new BasicAttribute(attr); for (String value : valueList) { attribute.add(value); } entry.put(attribute); } } ctx.createSubcontext(itemDn, entry);
      } catch (NamingException e){
        
throw e;
      }
finally{
        ctx.close();

       }

      }

attrValueMap保存条目的所有属性信息,添加条目的属性要根据其对应的objectClass的必填属性填写,不能将必填属性设为空值,否则添加时会抛出异常,错误代码65。

3,修改条目
public void updateUser(String ip,int port,String bindDN, String password, String itemDn, HashMap<String, ModifyAttribute> modifyAttrMap)
            throws NamingException {
        Hashtable<String, String> env = new Hashtable<String, String>();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldap://" + ip + ":" + port);
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, bindDn);
        env.put(Context.SECURITY_CREDENTIALS, password);
     DirContext ctx = null;
        try {
            ctx = new InitialDirContext(env);
            ModificationItem[] modificationItems = new ModificationItem[modifyAttrMap.size()];

            int i = 0;
            Iterator<String> it = modifyAttrMap.keySet().iterator();
            while (it.hasNext()) {
                ModifyAttribute ma = modifyAttrMap.get(it.next());
                modificationItems[i++] = new ModificationItem(ma.getType(), new BasicAttribute(ma.getAttr(), ma.getValue()));
            }

            ctx.modifyAttributes(itemDn, modificationItems);

        } catch (NamingException e) {
            throw e;
        }finally{    

      ctx.close();
      }

    }

4,删除条目

public void deleteUser(String ip,int port,String bindDn, String password, String itemDn) throws NamingException {
        if (null != itemDn && !itemDn.equals("")) {

            Hashtable<String, String> env = new Hashtable<String, String>();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
            env.put(Context.PROVIDER_URL, "ldap://" + ip + ":" + port);
            env.put(Context.SECURITY_AUTHENTICATION, "simple");
            env.put(Context.SECURITY_PRINCIPAL, bindDn);
            env.put(Context.SECURITY_CREDENTIALS, password);
       DirContext ctx = null; 
            try {
                ctx = new InitialDirContext(env);
                ctx.destroySubcontext(itemDn);
            } catch (NamingException e) {
                throw e;
            }finally{
          ctx.close();
       }
        }
    }
