Java OpenLdap服务器，SpringLDAP用户绑定（inetOrgPerson）没有这样的对象

我刚刚安装了一个OpenLDAP服务器，并尝试在其上连接、添加、获取用户和组。 由于我是ldap新手，如果您能分享关于spring ldap的教程，那将是非常好的：/

下面是我的绑定代码：

用户类别：

public class User implements Serializable{

    private String id;
    private String userName;
    private String firstName;
    private String lastName;
    private String email;
    private String password;
    private String department;
    private String groups[];
}

保存方法：

public User save( final User user ){
        init();
        Name dn = buildDn( user );
        Attributes attributes = buildAttributes( user );

        logger.info( "trying to save DN  " + dn + " and attributes " + attributes );

        ldapTemplate.bind( dn, null, attributes );

        // Update Groups
        for( String group : user.getGroups() ){
            try{
                DistinguishedName groupDn = new DistinguishedName();
                groupDn.add( "ou", "Groups" );
                groupDn.add( "cn", group );
                DirContextOperations context = ldapTemplate.lookupContext( groupDn );
                context.addAttributeValue( "memberUid", user.getUserName() );
                ldapTemplate.modifyAttributes( context );
            }
            catch( Exception e ){
                e.printStackTrace();
            }
        }

        logger.info( "successfuly saved " );
        return user;

    }

buildDN：

private Name buildDn( final User user ){
        DistinguishedName dn = new DistinguishedName();
        dn.add( "ou", "People" );
        if( user.getDepartment() != null ){
            dn.add( "ou", user.getDepartment() );
        }
        dn.add( "uid", user.getUserName() );
        return dn;
    }

构建属性：

private Attributes buildAttributes( final User user ){
        Attributes attrs = new BasicAttributes();
        BasicAttribute ocattr = new BasicAttribute( "objectClass" );
        // ocattr.add( "person" );
        ocattr.add( "inetOrgPerson" );
        attrs.put( ocattr );
        attrs.put( "cn", user.getFirstName() );
        // attrs.put( "rdn", "uid" ); // TODO check how to assign rdn
        attrs.put( "sn", user.getLastName() );
        attrs.put( "userPassword", "{SHA}" + this.encrypt( user.getPassword() ) );
        attrs.put( "mail", user.getEmail() );

        return attrs;
    }

这里有一个例外：

我找到了解决办法

dn.add( "ou", "People" );

我正在尝试将人员添加到人员组织单元，但它不存在

谢谢。

虽然您提供的代码肯定能满足您的需要，但库中包含的一些功能将使您的工作更轻松

最简单的方法是使用，它几乎删除了所有的锅炉板，并在域类上使用声明性映射

如果您决定继续使用，我鼓励您充分利用它的功能（更具体地说，您可以直接向指定的绑定方法提交DirContextOperation实例）：

有很多示例，源代码中也包含了一些示例来帮助您入门（有一个使用ODM的简单示例，另一个使用DirContextOperations，最后是一个使用ODM的完整用户管理应用程序）

---

最后，请注意DifferentizedName类在2.x版中已被弃用；您应该使用中的或实用程序方法来处理可分辨名称（如果您使用ODM，通常不必这样做）。

好的，谢谢您给出了这么好的答案，但我在ldap方面是一个真正的新手。你能分享一些教程吗？我如何创建ou单位？我无法创建一个。关于ODM最好的教程可能是。要创建ou条目，只需使用objectclass organizationalUnit创建一个条目，设置ou属性，就可以了。谢谢！非常好的知识。

Name dn = buildDn(user);
DirContextAdapter context = new DirContextAdapter(dn);

context.setAttributeValues("objectclass", new String[] {"top", "person"});
context.setAttributeValue("cn", user.getFullname());
// populate more attributes

ldapTemplate.bind(context);
