Elasticsearch学习笔记：Es与SpringBoot的整合

Elasticsearch的定义：Elasticsearch is a highly scalable open-source full-text search and analytics engine. 

Es与SpringBoot整合，首先导入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
</dependency>

然后在 application.properties 中添加配置信息

# Elasticsearch
spring.data.elasticsearch.cluster-nodes=localhost:9300

还有其他配置信息，可在SpringBoot手册中查到，可以根据需要进行配置

# ELASTICSEARCH (ElasticsearchProperties)
spring.data.elasticsearch.cluster-name=elasticsearch # Elasticsearch cluster name.
spring.data.elasticsearch.cluster-nodes= # Comma-separated list of cluster node addresses.
spring.data.elasticsearch.properties.*= # Additional properties used to configure the client.
spring.data.elasticsearch.repositories.enabled=true # Whether to enable Elasticsearch repositories.

# JEST (Elasticsearch HTTP client) (JestProperties)
spring.elasticsearch.jest.connection-timeout=3s # Connection timeout.
spring.elasticsearch.jest.multi-threaded=true # Whether to enable connection requests from multiple execution threads.
spring.elasticsearch.jest.password= # Login password.
spring.elasticsearch.jest.proxy.host= # Proxy host the HTTP client should use.
spring.elasticsearch.jest.proxy.port= # Proxy port the HTTP client should use.
spring.elasticsearch.jest.read-timeout=3s # Read timeout.
spring.elasticsearch.jest.uris=http://localhost:9200 # Comma-separated list of the Elasticsearch instances to use.
spring.elasticsearch.jest.username= # Login username.

# Elasticsearch REST clients (RestClientProperties)
spring.elasticsearch.rest.password= # Credentials password.
   spring.elasticsearch.rest.uris=http://localhost:9200 # Comma-separated list of the Elasticsearch instances to use.
   spring.elasticsearch.rest.username= # Credentials username.
