ELasticsearch的安装以及与spring-data-elasticsearch的整合使用

#Elasticsearch安装
这里本人使用的是docker镜像安装，至于怎么安装就不说了，贴一下配置最基本的配置文件就好

#集群名称，默认为elasticsearch， 命名规则为 es-产品名-ES版本
cluster.name: luckyqing

#节点名称，es启动时会自动创建节点名称，但你也可进行配置
node.name: es-46-68-76

#设置索引的分片数
#index.number_of_shards: 5

#设置索引的副本数
#index.number_of_replicas: 1

#是否为主节点，一个集群中建议只配置一个主节点
node.master: true

#数据存储位置
#path.data: /data1/elasticsearch/data

#这个参数是用来同时设置bind_host和publish_host上面两个参数 v2.0以上默认是127.0.0.1

network.host: 0.0.0.0

#设置对外服务的http端口,默认为9200
http.port: 9200

#设置节点间交互的tcp端口,默认是9300
transport.tcp.port: 9300

记住，elasticsearch是不允许root启动的，所以需要另外的用户启动，启动之后IP访问9200端口

安装基本上没问题了，但是要与java对接的话挺多坑的，下面坑一路写下来
正确的pom.xml先贴出来

这个问题的解决方法是在启动类的地方加上System.setProperty(“es.set.netty.runtime.available.processors”, “false”);

@SpringBootApplication(scanBasePackages = "com.lua.demo")
@MapperScan("com.lua.demo.dao")
public class DemoApplication {
    public static void main(String[] args) {
        System.setProperty("es.set.netty.runtime.available.processors", "false");
        SpringApplication.run(DemoApplication.class, args);
    }

第二个错：看报错 2.1

An attempt was made to call the method org.elasticsearch.common.settings.Settings$Builder.put(Ljava/util/Dictionary;)Lorg/elasticsearch/common/settings/Settings$Builder; but it does not exist. Its class, org.elasticsearch.common.settings.Settings$Builder, is available from the following locations:

    jar:file:/C:/Users/i/.m2/repository/org/elasticsearch/elasticsearch/6.4.2/elasticsearch-6.4.2.jar!/org/elasticsearch/common/settings/Settings$Builder.class

It was loaded from the following location:

    file:/C:/Users/i/.m2/repository/org/elasticsearch/elasticsearch/6.4.2/elasticsearch-6.4.2.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of org.elasticsearch.common.settings.Settings$Builder

springboot 默认加载的是最新版本的transport

其实这些都是版本的问题，Es版本控制,在pom文件的properties指定ES的版本

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        //这是后续加的，在最上面的pom。xml中也添加过
        <elasticsearch.version>5.6.10</elasticsearch.version>
    </properties>

还有一个报错，现在返回去截不到图了，大概意思是当使用@AutoWired的注入respority的时候会报错。
最后一个问题，通过IDEA新建项目的时候不要勾选nosql中的elasticseach，不然就算是上面这种配置也会报错。
只贴出来相关报错，有问题私信！
