一段操作LDAP的java代碼

java 代碼

public class LdapService {
    private Logger logger = Logger.getLogger(LdapService.class);

    private Properties env;

    private DirContext ctx;

    public void setEnv(Properties env) {
        this.env = env;
    }

    public NamingEnumeration search(String dn, String filter,
            String[] returningAttr) throws NamingException {
        try {
            ctx = new InitialDirContext(env);
            SearchControls constraints = new SearchControls();
            constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
            constraints.setReturningAttributes(returningAttr);
            return ctx.search(dn, filter, constraints);
        } finally {
            if (ctx != null) {
                try {
                    ctx.close();
                } catch (Exception ex) {
                    logger.error(ex);
                }
            }
        }
    }
}

下面是測試代碼：

java 代碼

public class LdapTest extends BaseUnitTest {

    public void testSerach() {
        LdapService ldap = (LdapService) this.applicationContext
                .getBean("ldapService");
        String dn = "ou=people,dc=ibm,dc=com";
        String[] returningAttr = null;
        String filter = "uid=c0001";
        try {
            NamingEnumeration n = ldap.search(dn, filter, returningAttr);
            if (n.hasMoreElements()) {
                SearchResult sr = (SearchResult) n.next();
                printAttributes(sr.getAttributes());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private void printAttributes(Attributes attributes) throws NamingException {
        String attrType;
        Attribute attr;
        NamingEnumeration ne;

        // Iterate through the attributes..
        for (NamingEnumeration a = attributes.getAll(); a.hasMore();) {
            attr = (Attribute) a.next();

            System.out.print(attr.getID() + ": ");

            ne = attr.getAll();
            while (ne.hasMore()) {
                System.out.print(ne.next());
            }

            System.out.print("\n");
        }
    }
}
