JNDI_LDAP实战十四

首先准备openLDAP ， window 版或linux版都可，

 

重点：

You need to add include schema/java.schema to your OpenLDAP configuration

否则利用JNDI LDAP provider 无法绑定对象。

 

1. 绑定对象person 到cn=user2,o=tt,c=cn

import java.io.Serializable;

 

import javax.naming.NamingException;

import javax.naming.Reference;

import javax.naming.Referenceable;

import javax.naming.directory.DirContext;

 

public class person implements Serializable {

/**

* 

*/

private static final long serialVersionUID = 1L;

private String name;

private int age;

 

public String getName() {

return name;

}

 

public void setName(String name) {

this.name = name;

}

 

public int getAge() {

return age;

}

 

public void setAge(int age) {

this.age = age;

}

 

public static void main(String[] args) {

// TODO Auto-generated method stub

 

}

 

 

 

 

}

 

绑定后可以看到LDAP的内容增加了一下内容

 

javaSerializedData 等信息。

并且可以通过LDAP的JNDI来进行进程间通信
