ElasticSearch5.3插件开发（一）控制台打印信息

自定义插件类继承org.elasticsearch.plugins.Plugin

本文最简单的一个插件，在控制台打印信息：

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目录下新建一个文件夹，然后放入jar包，添加配置文件plugin-descriptor.properties

文件内容如下
description=hello for ElasticSearch 

version=1.0  

name=HelloWorldPlugin  

site=${elasticsearch.plugin.site} 

jvm=true  

classname=org.elasticsearch.plugin.helloworld.MyFirstPlugin     //类全名

java.version=1.7  

elasticsearch.version=2.2.0 

isolated=${elasticsearch.plugin.isolated}
