LDAP身份验证(LDAP Authentication)

我有验证用户对ADS的要求。在此之前，我需要从ADS获取用户和用户的详细信息。现在用的弹簧和LDAP。任何人都可以建议我一个好办法做到这一点？一个例子是有帮助的。

我们所需要的所有必要的库。您可以下载使用该链接的所有jar文件。 http://hotfile.com/dl/9807349/836e03e/final_jar_col.rar.html这包含了所有我们需要的文件，包括公共图书馆，log4j的，等等。

创建以下类。所有的类可以放在一个包目录，你将它添加到包在你的方式。

定义两种功能。一个是让所有的联系人姓名，另一种是用于获取联系方式。

import java.util.List;

public interface ContactDAO {

    public List getAllContactNames();

    public List getContactDetails(String commonName);

}

LDAPContactDAO实现定义的接口。

import java.util.List;

import javax.naming.NamingException;
import javax.naming.directory.Attributes;
import javax.naming.directory.BasicAttribute;
import javax.naming.directory.BasicAttributes;

import org.springframework.ldap.AttributesMapper;
import org.springframework.ldap.LdapTemplate;
import org.springframework.ldap.support.DistinguishedName;
import org.springframework.ldap.support.filter.AndFilter;
import org.springframework.ldap.support.filter.EqualsFilter;

public class LDAPContactDAO implements ContactDAO{
    private LdapTemplate ldapTemplate;

    public void setLdapTemplate(LdapTemplate ldapTemplate) {
        this.ldapTemplate = ldapTemplate;
    }

    public List getAllContactNames() {
        return ldapTemplate.search("", "(objectClass=person)",
                new AttributesMapper() {
                    public Object mapFromAttributes(Attributes attrs)
                            throws NamingException {
                        return attrs.get("mail").get();
                    }
                });
    }

    public List getContactDetails(String objectclass){
        AndFilter andFilter = new AndFilter();
        andFilter.and(new EqualsFilter("objectClass",objectclass));
        System.out.println("LDAP Query " + andFilter.encode());
        return ldapTemplate.search("", andFilter.encode(),new ContactAttributeMapper());

    }
}

ContactDTO

public class ContactDTO {
