Java “我的所有类”的“仅用户”定义

我需要java类的帮助。我正在做一个有很多类的项目，这些类必须连接到我服务器的LDAP。在每个类中，我必须指定importjavax，即绑定到LDAP服务器的上下文。有一种方法可以只在一个类中指定javax和context，而在所有其他类上调用这个javax和context，而无需每次重写

我只想为我的所有类指定一次javax、hastable和env.put的导入部分：

package ldapUserManagement;


import javax.naming.*;
import javax.naming.directory.*;

import java.util.Hashtable;
import java.util.List;

public class Usagers
{

    private static final String String = null;
    private static Context result;

    public static void main(String[] args) 
    {

    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");

    env.put(Context.PROVIDER_URL, "ldap://192.168.0.5:389/dc=java,dc=local");
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, "java\\administrator");
        env.put(Context.SECURITY_CREDENTIALS, "*password*");
        env.put("java.naming.ldap.deleteRDN", "true");  


    try {...

我的目标是只在一个地方指定要导入的管理员凭据和javax

感谢你用一个清晰的例子来回答

谢谢你的快速帮助

对哈希表使用静态变量

您将始终能够通过用户访问它。getEnv

您可以使用HashMap options=newhashmap；看看我的ldap测试连接

该示例应该包含一个方法，以便外部类可以访问字段OP中提到的许多类：publicstatichashtable getEnv{returntable；}
