java读取ldif文件并创建新的节点
所需jar包ldap.jar、 jldap-4.3-source.jar
http://www.java2s.com/Code/Jar/l/Downloadldapjar.htm
浏览器输入http://maven.aliyun.com/nexus进入后搜索jldap,找到com.novell.ldap 这里我用的是4.3版本，点击source下载
https://www.novell.com/documentation/developer/samplecode/jldap_sample/
打开浏览器输入以上地址，Ldif2Ldap.java并找到LDIFReader.java.这个类就是用来读取ldif文件并添加到ldap目录服务中,再将ldap.jar放入项目中。
- 方法一：
使用Ldif2Ldap.java，传入相应的参数（<文件名称> <IP> <登录名> <密码>）就可以将ldif文件导入到ldap目录服务中。但这里需要注意ldif文件的格式，否则回报com.novell.ldap.ldif_dsml.LDIFReader: version: found 。。。
因为这里采用的是Novell 导入需要LDIF 1格式的文件，以下是LDIF 1文件的基本规则：
- 第一个非注释行必须是版本号：1.
- 版本号后面跟有一个或多个记录。
- 每个记录由多个字段组成，一行一个字段。
- 各行使用换行符或回车符/换行符对分隔。
- 各记录由一个或多个空行分隔。
- 存在两种不同类型的 LDIF 记录：内容记录和更改记录。对 LDIF 文件可以包含的记录数目没有限制，但它们必须属于同一类型。在同一个 LDIF 文件中不能既有内容记录又有更改记录。
- 以井字符 (#) 开头的行是注释行，在处理 LDIF 文件时将被忽略。
version:1 dn:: Yz3kuK3ljY7kurrmsJHlhbHlkozlm70= changetype:add objectClass: top objectClass: country c:: 5Lit5Y2O5Lq65rCR5YWx5ZKM5Zu9 dn:: bz3lm5vlt50sIGM95Lit5Y2O5Lq65rCR5YWx5ZKM5Zu9 changetype:add objectClass: top objectClass: organization o:: 5Zub5bed dn:: bz3miJDpg70sbz3lm5vlt50sIGM95Lit5Y2O5Lq65rCR5YWx5ZKM5Zu9 changetype:add objectClass: top objectClass: organization o:: 5oiQ6YO9
- 注：dn:安全 UTF-8 相对判别名 dn::Base64 编码的相对判别名
运行后，打开浏览器输入以下地址
https://www.netiq.com/communities/cool-solutions/cool_tools/gawors-excellent-ldap-browsereditor-v282/
下载LDAP Browser\Editor v2.8.2后双击lbe.j
ar,连接ldap后，就可以发现数据已成功的添加进去了
- 方法二：
使用Ldif2Ldap.java，传入相应的参数（<文件名称> <IP> <登录名> <密码>）就可以将ldif文件导入到ldap目录服务中。
int version = 1; int ldapPort = LDAPConnection.DEFAULT_PORT; int ldapVersion = LDAPConnection.LDAP_V3; String fileName = args[0]; String ldapHost = args[1]; String loginDN = args[2]; String password = args[3]; LDIFReader reader = null; LDAPEntry entry; LDAPMessage msg, retMsg; LdifImport readerTest = new LdifImport(); LDAPConnection lc = new LDAPConnection(); File file = new File(fileName); if(!file.exists()){ logger.error("要读取的文件不存在"); return false; } try { FileInputStream fis = new FileInputStream(new File(fileName)); reader = new LDIFReader(fis, version); } catch (Exception e) { logger.error("读取 " + fileName +"文件失败"); return false; }
这里LDIFReader类在方法一中调用的是ldap.jar中的类，考虑到ldif文件的格式，我在这里打算更改LDIFReader类中的源代码，在 jldap-4.3-source.jar 的工具包中，复制并修改。
