Question

我有以下代码连接LDAP，这对我来说很好 -

import java.util.ArrayList;
import java.util.Hashtable;
import java.util.List;

import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;

 private static final String LdapBaseDn = GlobalProps.getProperty(GlobalProps.PROP_LDAP_BASEDN); 
     private static  StringBuilder ldapQuery; 
     private static SearchControls ldapSearchControl; 

     public void setQuery(String query) {            
          ldapQuery = new StringBuilder(query);               
     } 

     public void setMaxResults(long maxResults) { 
          ldapSearchControl.setCountLimit(maxResults); 
     } 

    public static void main(String[] args) {

        //LdapContext ctx = null;


        NamingEnumeration<SearchResult> searchResults = null;
        List<LdapPerson> people = new ArrayList<LdapPerson>();

        try{

        Hashtable<Object,Object> env = new Hashtable<>();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.SECURITY_AUTHENTICATION, "Simple");
        env.put(Context.SECURITY_PRINCIPAL, "Global\\"+Util.usenam);
        env.put(Context.SECURITY_CREDENTIALS, Util.password);
        env.put(Context.PROVIDER_URL, "LDAP://stladdc01.global.sial.com:389"); 
        //ctx = new InitialLdapContext(env, null);

          DirContext ctx = new InitialDirContext(env);
            boolean result = ctx != null;
            if(ctx != null)
               ctx.close();

            System.out.println(result);

        }catch(Exception e){
            e.printStackTrace();

        }

System.out.println(result)输出为true。但我需要代码从LDAP目录中获取同一用户的emailID。任何人都可以帮我吗？

您可以在代码中包含这些更改，看看它是否有效。别忘了通过username。希望这会给你一些想法。

public static void main(String[] args) {
        NamingEnumeration<SearchResult> searchResults = null;
        try {
            Hashtable<Object, Object> env = new Hashtable<>();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
            env.put(Context.SECURITY_AUTHENTICATION, "Simple");
            env.put(Context.SECURITY_PRINCIPAL, "Global\\" + Util.usenam);
            env.put(Context.SECURITY_CREDENTIALS, Util.password);
            env.put(Context.PROVIDER_URL, "LDAP://stladdc01.global.sial.com:389");
            DirContext ctx = new InitialDirContext(env);
            if (ctx != null) {
                Test test = new Test();
                // pass your actual username here.....
                test.getUserAttributes("username", ctx);
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private void getUserAttributes(String username, LdapContext ctx) {
        try {
            SearchControls constraints = new SearchControls();
            constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
            /* String[] attrIDs = { "mail", "telephonenumber" }; 
             You can have multiple attributes like SN, telephonenumber, mail
            etc.. */
            String[] attrIDs = { "mail" };
            constraints.setReturningAttributes(attrIDs);
            NamingEnumeration answer = ctx.search("DC=YourDomain,DC=com", "sAMAccountName=" + username, constraints);
            if (answer.hasMore()) {
                Attributes attrs = ((SearchResult) answer.next()).getAttributes();
                System.out.println("mail " + attrs.get("mail"));
            } else {
                throw new Exception("Invalid User");
            }

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
