Spring Boot-在不删除代码或不更改POM的情况下禁用嵌入式ElasticSearch

Question

I'm looking for a way to prevent ElasticSearch for starting (embedded or separate server) in a Spring Boot project. ES is currently not in use, but will be at a later stage in the project.

If I remove the lines from the POM, my code needs major updates, because all annotations to ES cannot be found anymore.

Is there a way I can keep my project intact, but prevent ES from launching (embedded)?

My goal is to speed up restarts for the time being, when ES is not in use.

Or course, I could also run ES as a separate server, but I don't want to spend the time.

Thanks

Answer 1

Add the following exclude to your @SpringBootApplication

import org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchAutoConfiguration;

@SpringBootApplication(exclude = ElasticsearchAutoConfiguration.class)

Answer 2

In your local application.properties

spring.autoconfigure.exclude = org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchAutoConfiguration,org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchDataAutoConfiguration

In production override to force the connection

spring.data.elasticsearch.cluster-nodes = someip:9300
spring.autoconfigure.exclude = none

Probability you will need to make ElasticsearchTemplate @Lazy or put it under a @Profile("production") class

Answer 3

In case your are using Java High Level REST Client, then the solution is as the following:

@EnableAutoConfiguration(exclude = RestClientAutoConfiguration.class )

Answer 4

I found this way to disable/enable Elasticsearch in Spring Boot

in application.properties:

elastic_enable=false

in elastic config file:

@Value("${elastic_enable}") boolean elastic_enable;

@Bean public Client a() throws UnknownHostException {
    if (elastic_enable) 
        return TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(elastic_host), 9300));
    else 
        return TransportClient.builder().build();
}

Answer 5

You should exclude this two Spring Boot Auto Configurations:

ElasticsearchAutoConfiguration.class, ElasticsearchDataAutoConfiguration.class

Also if you have @Configuration class for your Elastic or @Bean for the ElasticsearchTemplate be sure to comment them out.

Answer 6

I have just disabled embedded elasticsearch in spring boot 1.5.8 by adding the following exclude to my @SpringBootApplication.

Hope this can help.

import org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchAutoConfiguration;
import org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchDataAutoConfiguration;
import org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchRepositoriesAutoConfiguration;

@SpringBootApplication(exclude = {ElasticsearchAutoConfiguration.class,ElasticsearchDataAutoConfiguration.class, ElasticsearchRepositoriesAutoConfiguration.class})
