SPRING BOOT+ELASTICSEARCH+RABBITMQ

• 直接进入正题 构思的流程图：

. 安装RABBITMQ

echo 'deb http://www.rabbitmq.com/debian/ testing main' | sudo tee /etc/apt/sources.list.d/rabbitmq.listwget -O- https://www.rabbitmq.com/rabbitmq-release-signing-key.asc | sudo apt-key add -sudo apt-get updatesudo apt-get install rabbitmq-serversudo rabbitmqctl add_user admin admin sudo rabbitmqctl set_user_tags admin administratorsudo rabbitmq-plugins enable rabbitmq_managementhttp://192.168.10.69:15672

. 安装elasticSearch

注：spring-boot-starter-data-elasticsearch不支持高版本es采用2.4.4版本~ 另外es自身不带可视化页面，需要安装head~

https://www.elastic.co/products/elasticsearch download debdpkg -i elasticsearch-2.4.4.deb/etc/init.d/elasticsearch start head：cd elasticsearch-2.4.4/bin/plugin/usr/share/elasticsearch/bin/plugin install mobz/elasticsearch-headhttp://192.168.10.69:9200/_plugin/head/

. 最繁琐的部署环节已经完成 踩了无数个坑 心累~
接下来首先在主项目配置rabbit provider

amqp-client-3.5.4.jarspring-amqp-1.5.6.RELEASE.jar

<!-- mq start --><!-- connection --><rabbit:connection-factory id="connectionFactory"        host="${mq.host}" username="${mq.username}" password="${mq.password}"        port="${mq.port}" virtual-host="${mq.vhost}" /><rabbit:admin connection-factory="connectionFactory" id="amqpAdmin" /><!-- json convert --><bean id="jsonMessageConverter"        class="org.springframework.amqp.support.converter.Jackson2JsonMessageConverter" /><!-- es queue --><rabbit:queue id="es_queue" name="es_queue" durable="true"        auto-delete="false" exclusive="false" /><!-- exchange --><rabbit:direct-exchange name="es_exchange" id="es_exchange"        durable="true" auto-delete="false">        <rabbit:bindings>            <rabbit:binding queue="es_queue" key="es_queue" />        </rabbit:bindings></rabbit:direct-exchange><!-- template --><rabbit:template id="amqpTemplate" exchange="es_exchange"        connection-factory="connectionFactory" message-converter="jsonMessageConverter"/><!-- mq end -->

@Servicepublic class EsMqServiceImpl implements EsMqService {    @Autowired    private AmqpTemplate amqpTemplate;    @Override    public void pushToMessageQueue(String exchange, String route, String message) {        amqpTemplate.convertAndSend(exchange, route, message);    }}

rabbitmq还是值得一学的，稍微看了下《RabbitMQ实战 高效部署分布式消息队列》，看到第四章实在看不下去了，有点涩，又缺乏实战的机会。但感觉基本概念理解了，平时操作也够用了。

. 搜索项目搭建

这里使用SPRING-BOOT代替SPRING 2个原因：1.SPRING-BOOT实在是方便2.是因为自己想实战下新建方法： 1.STS插件2.http://projects.spring.io/spring-boot/ 

.pom

        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <!-- 热部署 -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-devtools</artifactId>            <optional>true</optional>        </dependency>         <!-- ES -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-data-elasticsearch</artifactId>        </dependency>        <!-- RabbitMQ -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-amqp</artifactId>        </dependency>

.application.properties

spring.application.name=elasticsearch#mqspring.rabbitmq.host=localhostspring.rabbitmq.port=5672spring.rabbitmq.virtual-host=panchenspring.rabbitmq.username=panchenspring.rabbitmq.password=panchen#esspring.data.elasticsearch.cluster-nodes=localhost:9300spring.data.elasticsearch.cluster-name=elasticsearchspring.data.elasticsearch.repositories.enabled=true  

.entity

/** * @Field ：FieldType type() default FieldType.Auto;#自动检测属性的类型 FieldIndex index() *        default FieldIndex.analyzed;#默认情况下分词 DateFormat format() default *        DateFormat.none; String pattern() default ""; boolean store() default *        false;#默认情况下不存储原文 String searchAnalyzer() default "";#指定字段搜索时使用的分词器 *        String indexAnalyzer() default "";#指定字段建立索引时指定的分词器 String[] *        ignoreFields() default {};#如果某个字段需要被忽略 boolean includeInParent() *        default false; 不加则默认值 * @Document: 索引库命名 / 类型 / 分区数 / 每个分区的备份数 / 刷新间隔 / 文件存储类型 */@Document(indexName = "userinfo_index", type = "userInfo", shards = 5, replicas = 1, refreshInterval = "-1", indexStoreType = "fs")public class UserInfo implements Serializable {    private static final long serialVersionUID = 551589397625941750L;    @Id    private Long id;    private String name;    public Long getId() {        return id;    }    public void setId(Long id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public static long getSerialversionuid() {        return serialVersionUID;    }    @Override    public String toString() {        return "UserInfo [id=" + id + ", name=" + name + "]";    }}

.repository ~~ dao

/** * 接口中自定义方法，在方法名中包含T中字段名 查询关键字包括find…By, read…By, query…By, count…By, and * get…By,And and Or连接 泛型的参数分别是实体类型和主键类型 *  * @author pc */public interface UserInfoRepository extends ElasticsearchRepository<UserInfo, Long> {}

. test

@SpringBootApplication//这个注解是个大坑！！！@EnableElasticsearchRepositories@RunWith(SpringJUnit4ClassRunner.class)@SpringBootTest(classes = CompanyElasticsearchApplication.class)public class SearchRepositoryTest {    @Autowired    // spring Boot默认会扫描启动类同包以及子包下的注解    private UserInfoRepository userInfoRepository;    @Test    public void test() {        System.out.println("start");        UserInfo userInfo=new UserInfo();        userInfo.setId(1l);        userInfo.setName("潘晨");        System.out.println(userInfoRepository.save(userInfo));        System.out.println("新增成功");        System.out.println(userInfoRepository.count());        System.out.println("查询成功");        System.out.println("end");    }}

. OK！
