【问题描述】：

我必须从 LDAP 服务器读取操作属性（createTimeStamp、entryUUID 等）。

我尝试实现自己的 UserDetailContextMapper 但没有成功。

目前我的代码如下所示

Override
public void configure(AuthenticationManagerBuilder auth) throws Exception 
    auth
            .ldapAuthentication()
            .userSearchFilter("uid=0")
            .groupSearchBase("ou=users")
            .userDetailsContextMapper(userContextMapper())
            .contextSource(contextSource());


@Bean
public LdapContextSource contextSource() 
    LdapContextSource contextSource = new LdapContextSource();
    contextSource.setUrl("ldap://ldap.company.pl:389");
    contextSource.setBase("dc=company,dc=com");
    contextSource.afterPropertiesSet();
    return contextSource;


@Bean
public UserDetailsContextMapper userContextMapper() 
    return new CustomUserDetailContextMapper();

我的 UserDetailContextMapper 实现：

public class CustomUserDetailContextMapper implements UserDetailsContextMapper 

@Override
public UserDetails mapUserFromContext(DirContextOperations ctx, String username, Collection<?
        extends GrantedAuthority> authorities) 
    AutoUser user = new AutoUser();

    user.setCreateTimeStamp(ctx.getStringAttribute("createTimestamp"));
    user.setUUID(ctx.getStringAttribute("entryUUID"));
    user.setEmail(ctx.getStringAttribute("mail"));
    return user;


@Override
public void mapUserToContext(UserDetails user, DirContextAdapter ctx) 
    //default impl

我试过Attributes attributes = ctx.getAttributes(username, new String[] "*", "+");

在mapUserFromContext() 方法中，但如果我通过username，我会收到NamingException。

我正在考虑实现 ldapTemplate.lookup()，但我不确定在哪里实现它，我尝试使用 ldapTemplate 执行 userRepo 类，但我通过任何 DN 都得到了NameNotFoundException。

我可以使用这样的查询从 LDAP 中检索对象：

public Object getAll()
    return ldapTemplate.search(query()
    .where("entryUUID").is("<HasToPassUUIDFromLDAP"), new PersonAttributesMapper());

但我需要传递完整的属性值，这不是重点，因为我要检索此值，而不是具有此值的对象。

【问题讨论】：

你收到了什么NamingException？请完整的错误消息和堆栈跟踪。注意getAttributes() 的第一个参数是 RDN，而不是用户名。

使用堆栈跟踪编辑帖子。实际上，如果传递了任何带有名称的名称/字符串，ctx.getAttributes 会抛出异常。

这是一个 RDN。不是 DN。相对专有名称。相对于您调用它的上下文的名称空间。您似乎在这里混合使用了几种 API。

【参考方案1】：

    ctx.getAttributes(username, new String[] "*", "+");

用户名 - 根据文档，这应该是 DN 这就是 LDAP 知道您从哪条记录中提取数据的方式

第二个参数，如果设置为null，则检索所有属性

我相信您的错误被抛出是因为您传递的是 用户名 而不是 专有名称。
