                  问题描述

                  我想显示 LDAP 目录架构中存在的所有对象类,以帮助用户输入可用的对象类以添加新条目.

                  I want to show all objectclasses present in schema of LDAP Directory to help user to input available objectclasses for adding new entry.

                  DirContext schema = ctx.getSchema("");
                  Attributes answer = schema.getAttributes("ClassDefinition/person");
                  

                  但这仅显示有关人员的信息.

                  but that shows information about person only.

                  推荐答案

                  你要查询subschema subentry 即cn=schema(以下代码已针对 Apache Directory Server 进行了测试)

                  You have to query the subschema subentry i.e cn=schema (the below code has been tested against the Apache Directory Server)

                  DirContext ctx = new InitialLdapContext( env, null );
                  
                  SearchControls searchControls = new SearchControls();
                  searchControls.setSearchScope( SearchControls.OBJECT_SCOPE );
                  searchControls.setReturningAttributes( new String[]
                      { "objectClasses" } );
                  NamingEnumeration<SearchResult> results = ctx.search( "cn=schema", "(ObjectClass=*)", searchControls );
                  
                  SearchResult result = results.next();
                  Attributes entry = result.getAttributes();
                  
                  Attribute objectClasses = entry.get( "objectClasses" );
                  System.out.println( objectClasses );
