搭建模块

创建二个项目

gmall-list-service的appliction.properties:

server.port=8073

spring.datasource.url=jdbc:mysql://localhost:3306/gmall?characterEncoding=UTF-8

spring.datasource.username=root

spring.datasource.password=root

mybatis.configuration.map-underscore-to-camel-case=true

mybatis.mapper-locations=classpath:mapper/*Mapper.xml

spring.dubbo.registry.protocol=zookeeper

spring.dubbo.registry.address=192.168.0.100:2181

spring.dubbo.application.name=gmall-list-service

spring.dubbo.protocol.name=dubbo

spring.dubbo.base-package=com.javawxid

spring.elasticsearch.jest.uris=http://192.168.0.100:9200

logging.level.root=info

gmall-list-service的pom.xml:

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

com.javawxid.gmall

gmall-parent

gmall-list-service

0.0.1-SNAPSHOT

gmall-list-service

Demo project for Spring Boot

com.javawxid.gmall

com.javawxid.gmall

gmall-api

org.springframework.boot

spring-boot-starter-data-elasticsearch

io.searchbox

jest

5.3.3

net.java.dev.jna

jna

4.5.1

org.springframework.boot

spring-boot-maven-plugin

其中jest和jna请将版本号，部分纳入gmall-parent中管理。spring-boot-starter-data-elasticsearch不用管理版本号，其版本跟随springboot的1.5.10大版本号。

gmall-list-web的appliction.properties:

server.port=8083

spring.dubbo.registry.address=192.168.0.100:2181

spring.dubbo.protocol.name=dubbo

spring.dubbo.application.name=gmall-list-web

spring.dubbo.base-package=com.javawxid

spring.dubbo.consumer.timeout=600000

spring.dubbo.consumer.check=false

spring.thymeleaf.mode=LEGACYHTML5

spring.thymeleaf.cache=false

logging.level.root=info

2、 关于es的java 客户端的选择

目前市面上有两类客户端

一类是TransportClient 为代表的ES原生客户端，不能执行原生dsl语句必须使用它的Java api方法。

另外一种是以Rest Api为主的missing client，最典型的就是jest。 这种客户端可以直接使用dsl语句拼成的字符串，直接传给服务端，然后返回json字符串再解析。

两种方式各有优劣，但是最近elasticsearch官网，宣布计划在7.0以后的版本中废除TransportClient。以RestClient为主。

所以在官方的RestClient 基础上，进行了简单包装的Jest客户端，就成了首选，而且该客户端也与springboot完美集成。

3、插入数据

PUT /movie_chn/movie/1

{ "id":1,

"name":"红海行动",

"doubanScore":8.5,

"actorList":[

{"id":1,"name":"张译"},

{"id":2,"name":"海清"},

{"id":3,"name":"张涵予"}

]

}

PUT /movie_chn/movie/2

{

"id":2,

"name":"湄公河行动",

"doubanScore":8.0,

"actorList":[

{"id":3,"name":"张涵予"}

]

}

PUT /movie_chn/movie/3

{

"id":3,

"name":"红海事件",

"doubanScore":5.0,

"actorList":[

{"id":4,"name":"张晨"}

]

}

4、在测试类中测试ES

package com.javawxid;

import io.searchbox.client.JestClient;

import io.searchbox.core.Search;

import io.searchbox.core.SearchResult;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

import java.io.IOException;

import java.util.HashMap;

import java.util.List;

@RunWith(SpringRunner.class)

@SpringBootTest

public class GmallListServiceApplicationTests {

@Autowired

JestClient jestClient;

@Test

public void testEs() throws IOException {

String query="{\n" +

" \"query\": {\n" +

" \"match\": {\n" +

" \"actorList.name\": \"张译\"\n" +

" }\n" +

" }\n" +

"}";

Search search = new Search.Builder(query).addIndex("movie_chn").addType("movie").build();

SearchResult result = jestClient.execute(search);

List> hits = result.getHits(HashMap.class);

for (SearchResult.Hit hit : hits) {

HashMap source = hit.source;

System.err.println("source = " + source);

}

}

}

打印结果：

source = {doubanScore=8.5, es_metadata_id=1, name=红海行动, actorList=[{id=1.0, name=张译}, {id=2.0, name=海清}, {id=3.0, name=张涵予}], id=1.0}

source = {doubanScore=5.0, es_metadata_id=3, name=红海事件, actorList=[{id=4.0, name=张晨}], id=3.0}

source = {doubanScore=8.0, es_metadata_id=2, name=湄公河行动, actorList=[{id=3.0, name=张涵予}], id=2.0}

以上技术方面的准备就做好了。
