Java 使用Spring Boot从LDAP排序记录

如何正确地从LDAP目录中获取已排序的记录。由于数据量大，将所有数据加载到内存然后进行排序非常耗时。 这就是为什么我希望（使用SpringBoot/SpringLDAP）从LDAP中获取已排序的记录

我试图在@Repository中创建

@Repository
public interface XxxRepository extends LdapRepository<Xxx>, Serializable {

   List<Xxx> findAllByOrderByNameAsc(LdapQuery ldapQuery);

}

我的@服务

public void search() {
   String filterConditions = "(&(objectClass=Xxx)";
   filterConditions += "(name=*)";
   LdapQuery query = query().base(BASE_UNIT).filter(filterConditions + ")");
   List<Xxx> xxx= xxxRepository.findAllByOrderByNameAsc(query);
}

公共作废搜索（）{
字符串筛选条件=“（&（objectClass=Xxx）”；
过滤条件+=“（名称=*）”；
LdapQuery query=query（）.base（base_单位）.filter（filterConditions+）；
List xxx=xxxRepository.findAllByOrderByNameAsc（查询）；
}

我在这里找到了答案：

它使用了SortControlDirContextProcessor

供参考这与JPA API毫无关系

public void search() {
   String filterConditions = "(&(objectClass=Xxx)";
   filterConditions += "(name=*)";
   LdapQuery query = query().base(BASE_UNIT).filter(filterConditions + ")");
   List<Xxx> xxx= xxxRepository.findAllByOrderByNameAsc(query);
}

public void testSearch_SortControl_ConvenienceMethod() {
    SortControlDirContextProcessor requestControl;

    // Prepare for first search
    requestControl = new SortControlDirContextProcessor("cn");
    tested.search(BASE, FILTER_STRING, searchControls, callbackHandler,
            requestControl);
    int resultCode = requestControl.getResultCode();
    boolean sorted = requestControl.isSorted();
    assertThat("Search result should have been sorted: " + resultCode, sorted).isTrue();
    List list = callbackHandler.getList();
    assertSortedList(list);
}
