自定義插件類繼承org.elasticsearch.plugins.Plugin

本文最簡單的一個插件，在控制臺打印信息：

package es.plugins;

import org.elasticsearch.plugins.ActionPlugin;
import org.elasticsearch.plugins.Plugin;

import java.util.Collections;
import java.util.List;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.elasticsearch.rest.RestHandler;


public class MyFirstPlugin extends Plugin implements ActionPlugin{
?? ?private final static Logger LOGGER = LogManager.getLogger(MyFirstPlugin.class);
??? public MyFirstPlugin() {
??????? super();
??????? LOGGER.info("This is my fisrt Plugin");
??????? LOGGER.info("This is my fisrt Plugin");
??????? LOGGER.info("This is my fisrt Plugin");
??????? LOGGER.info("This is my fisrt Plugin");
??????? LOGGER.info("This is my fisrt Plugin");
??????? LOGGER.info("This is my fisrt Plugin");
??????? LOGGER.info("This is my fisrt Plugin");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??????? LOGGER.warn("Create the Basic Plugin and installed it into elasticsearch");
??? }
?? ?
?
}

打包成jar包，在plugin目錄下新建一個文件夾，然后放入jar包，添加配置文件plugin-descriptor.properties

文件內(nèi)容如下
description=hello?for?ElasticSearch?

version=1.0??

name=HelloWorldPlugin??

site=${elasticsearch.plugin.site}?

jvm=true??

classname=org.elasticsearch.plugin.helloworld.MyFirstPlugin???? //類全名

java.version=1.7??

elasticsearch.version=2.2.0?

isolated=${elasticsearch.plugin.isolated}?

總結(jié)
