[英]Can Spring LdapTemplate stream results?
I am trying to query an active directory for ALL person objects. 我试图查询所有人对象的活动目录。 There are over 700,000
results which are way too many to read into a List
. 有超过700,000
结果太多,无法读入List
。 My current solution is using paging to get all of the results but I would much rather use the Java-8 Stream-API to get them instead. 我目前的解决方案是使用分页来获取所有结果,但我宁愿使用Java-8 Stream-API来获取它们。 Unfortunately, I have not found any methods on LdapTemplate
that return a Stream
object. 不幸的是,我没有在LdapTemplate
上找到任何返回Stream
对象的方法。
I know that this can return all of the results: 我知道这可以返回所有结果:
public List<LdapPerson> findAll() {
return ldapTemplate.search("","(objectClass=person)", mapper);
}
but what I'm looking for is something that can return: 但我正在寻找的是可以返回的东西:
public Stream<LdapPerson> findAll(){
return ldaptemplate.?????????;
}
Can anyone point me in the right direction? 谁能指出我正确的方向?
No, the LdapTemplate
doesn't provide a method that directly returns a Stream<T>
from a searched elements. 不, LdapTemplate
不提供直接从搜索元素返回Stream<T>
的方法。 However, since the method, LdapTemplate::search
returns a List<T>
, then you can use a characteristics of any Collection<T>
that is convertible to Stream<T>
using a simple call of collection.stream()
method: 但是,由于方法LdapTemplate::search
返回List<T>
,因此您可以使用collection.stream()
方法的简单调用来使用可转换为Stream<T>
的任何 Collection<T>
的特性:
public Stream<LdapPerson> findAll() {
return ldapTemplate.search("", "(objectClass=person)", mapper).stream();
}
