用途

項(xiàng)目中使用了 dubbo，注冊(cè)中心使用的 zookeeper，使用 zookeeper 實(shí)現(xiàn)了一個(gè)簡(jiǎn)單的分布式鎖（依賴 curator），因?yàn)榕渲梦募嬖?dubbo.registry 配置，為了直接使用這個(gè)地址來(lái)創(chuàng)建分布式鎖，寫了一個(gè)簡(jiǎn)單的方法來(lái)提取 zookeeper 地址。

效果

dubbo.registry 有多種配置方式，支持所有情況，下面是常見(jiàn)的例子和提取結(jié)果：

				?

									zookeeper://localhost:2181

									zookeeper://localhost:2181?client=zkclient

									zookeeper://localhost:2181?backup=localhost:2182,localhost:2183

									zookeeper://localhost:2181?client=zkclient&backup=localhost:2182,localhost:2183

									------------結(jié)果------------

									optional[localhost:2181]

									optional[localhost:2181]

									optional[localhost:2181,localhost:2182,localhost:2182]

									optional[localhost:2181,localhost:2183,localhost:2183]

代碼

				?

									import java.util.optional;

									public class zookeeperurl {

									  public static final string prefix = "zookeeper://";

									  public static final string backup = "backup=";

									  public static optional<string> convertdubboregistrytozookeeperurl(string dubboregistry){

									    stringbuilder zookeeperurl = new stringbuilder();

									    if(dubboregistry != null && dubboregistry.startswith(prefix)){

									      dubboregistry = dubboregistry.substring(prefix.length());

									      int index = dubboregistry.indexof("?");

									      if(index > 0){

									        zookeeperurl.append(dubboregistry.substring(0, index));

									        dubboregistry = dubboregistry.substring(index + 1);

									        string[] dubboregistries = dubboregistry.split("&");

									        for (int i = 0; i < dubboregistries.length; i++) {

									          if(dubboregistries[i].startswith(backup)){

									            string[] backups = dubboregistries[i].substring(backup.length()).split(",");

									            for (int j = 0; j < backups.length; j++) {

									              zookeeperurl.append(",").append(backups[i]);

									            }

									          }

									        }

									      } else {

									        zookeeperurl.append(dubboregistry);

									      }

									      return optional.of(zookeeperurl.tostring());

									    }

									    return optional.empty();

									  }

									  public static void main(string[] args) {

									    system.out.println(convertdubboregistrytozookeeperurl("zookeeper://localhost:2181"));

									    system.out.println(convertdubboregistrytozookeeperurl("zookeeper://localhost:2181?client=zkclient"));

									    system.out.println(convertdubboregistrytozookeeperurl("zookeeper://localhost:2181?backup=localhost:2182,localhost:2183"));

									    system.out.println(convertdubboregistrytozookeeperurl("zookeeper://localhost:2181?client=zkclient&backup=localhost:2182,localhost:2183"));

									  }

									}
