Java Naming and Directory Interface (JNDI) API - NIS連線實作教學

Sun JNDI 官方網站

nis.jar為NIX所需Lib

範例程式如下：

import java.util.Properties;

import javax.naming.NameClassPair;

import javax.naming.NamingEnumeration;

import javax.naming.NamingException;

import javax.naming.directory.DirContext;

import javax.naming.directory.InitialDirContext;

import javax.naming.directory.Attribute;

import javax.naming.directory.Attributes;

public class TestJndi {

public static void main(String[] args) {

Properties env = new Properties();

env.put(DirContext.INITIAL_CONTEXT_FACTORY,

"com.sun.jndi.nis.NISCtxFactory");

env.put(DirContext.PROVIDER_URL, "nis://127.0.0.1/nisdomainname");

try {

InitialDirContext ctx = new InitialDirContext(env);

NamingEnumeration list = ctx.list("system/passwd");

while (list.hasMoreElements()) {

String username = list.nextElement().getName();

Attributes atts = ctx

.getAttributes("system/passwd/" + username);

System.out.println(atts.get("uidNumber").get());

System.out.println(atts.get("gidNumber").get());

System.out.println(atts.get("cn").get());

System.out.println(atts.get("homeDirectory").get());

System.out.println(atts.get("userPassword").get());

System.out.println(atts.get("nisMapEntry").get());

}

} catch (NamingException ex) {

ex.printStackTrace();

}
