背景
LDAP听上去耳熟能详，可真要用Java去写一个通用性高的数据同步服务好像需要了解的东西又得特别多，能查到的东西又多是断章取义。最近断断续续的折腾了3周，基本上搞了一个这玩意，打算陆续分享给大家吧，由于相关东西不是一篇能讲完的，所以打算搞个小专题吧，希望给喜欢抄作业的朋友们有所帮助。
上一篇写了一个LDAP部署教程：小白级CentOS下yum方式安装OpenLDAP（SSL）及phpLDAPadmin部署教程，这次先介绍一下测试时需要使用到的LDAP数据工具。计划下一篇最后为大家介绍一下LDAP同步服务的实现思路。
1. 工具参数介绍
参数名称 | 类型 | 说明 | 备注 |
host | String | LDAP服务器地址 | |
port | Integer | LDAP服务器端口 | |
bindDn | String | 绑定 DN | |
bindPassword | String | 绑定 DN 密码 | |
baseDn | String | 根节点DN | |
ouBreadthPerNode | Integer | 部门广度/父节点 | Must >0 |
ouDepth | Integer | 部门深度 | Must >0 |
personBreadthPerNode | Integer | 用户广度/父节点 | Must >0 |
uidNumberBegin | Integer | 用户ID开始值 | Must >0 |
gidNumber | Integer | LDAP用户组ID | Must >0 |
opType | Integer | 操作类型 | 1：创建数据；2：清除数据； |
2. 思路简介绍
分享这个工具目的主要是2点：
1、如何把循环嵌套改为自递归的写法（因为不能搞一个只能创建固定深度的死的工具，例如说只能构建3级部门，如果要变为4级则需要加一层循环去改代码）
2、如何构造中文姓名、部门名称。
2.1 创建数据
- 根据参数构建一颗LDAP条目数据树，为了构建这棵树，工具中定义了一个简单的树化的数据结构（详见：TreeNode）;另外，由于直接把部门的深度定义为外部输入参数，因此在树的构建中需要进行自递归。简单来说，如何把以下循环嵌套代码改为递归（详见：LdapDataToolHelper.buildLdapEntryTree()方法）：
void loop()
{
for(int i=1;i<4;i++)
{
System.out.println(i);
for(int j=1;j<4;j++)
{
System.out.println(i + "-" + j);
for(int k=1;k<4;k++)
{
System.out.println(i + "-" + j + "-" + k);
}
}
}
}- 将构建好的LDAP条目数据树写入LDAP服务器，为了保障父节点一定在子节点之前完成写入，在树的遍历过程中需要保障其“自上而下”的顺序。
- 为了让构造的数据看起来好一点，对于人和部门条目数据的构造，进行了相对真实的人名和部门中文名称的随机生成（详见：ChineseUtils.java），数据生成效果如下（-ouBreadthPerNode 3 -ouDepth 2 -personBreadthPerNode 5 的构建效果）：
2.2 清除数据
- 为了删除某个BaseDN下的所有的人和部门数据，一般来说需要从下自上的去遍历LDAP条目树，因为常见DN删除方式，如果该DN下有子节点数据，则删除操作会被拒绝。为了偷懒，我这里采用SubtreeDelete方式，从而只需要找出BaseDN下的一级人和部门的条目，然后进行一次删除即可。
3. 工具代码
代码没多少，直接上代码吧。
