我的第一个整合elasticsearch\web的基于springboot框架的页面

1，连接es

新建EsController类

package com.example.demo.controller;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;

import javax.annotation.PostConstruct;
import java.net.InetAddress;

@Controller
public class EsController {
    private final static Log logger = LogFactory.getLog(EsController.class);
    @Value("${es.cluster.name}")
    String es_cluster_name;
    @Value("${es.cluster.ip}")
    String es_cluster_ip;
    @Value("${es.cluster.trans.port}")
    String es_cluster_trans_port;
    @Value("${es.shield.user.password}")
    String es_shield_user_password;
    @Value("${es.shield.enable}")
    private Boolean shieldEnable = Boolean.TRUE;


    @PostConstruct
    public TransportClient init() {
        Settings settings = Settings.settingsBuilder().put("cluster.name", es_cluster_name).put("shield.user", es_shield_user_password).build();
        TransportClient client = TransportClient.builder().addPlugin(ShieldPlugin.class).settings(settings).build();
        try {
            String[] ips = es_cluster_ip.split(",");
            for (int i = 0; i < ips.length; i++) {
                InetAddress esIP = InetAddress.getByName(ips[i]);
                int esPORT = Integer.parseInt(es_cluster_trans_port);
                client.addTransportAddress(new InetSocketTransportAddress(esIP, esPORT));
            }
            if (client == null) {
                logger.warn("es无法连接，client为空");
            }
        } catch (Exception e) {
            logger.error("es连接时错误");
        }
        return client;
    }


}

会发现

1.Settings.settingsBuilder()

2.TransportClient.builder().addPlugin(ShieldPlugin.class).settings(settings).build()

标红，证明缺少jar包;

已知Settings类在org.elasticsearch.common.*;下,所以猜测一定是版本不对

在pom文件中添加依赖

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch</artifactId>
    <version>2.3.5</version>
</dependency>

发现1编译通过，2依然不对。

再加依赖

<dependency>
   <groupId>org.elasticsearch.plugin</groupId>
   <artifactId>shield</artifactId>
   <version>2.2.0</version>
</dependency>

1和2都调试通过。

但此时

，不用管，不影响程序。

先这样，明天补，今天下班了
