SpringBoot + ES + Redis 충돌 에러

Spring boot에서 세션공유를 위해 Redis와  ES를 동시에 쓰는경우에 가끔 에러가 발생한다.

 

Port충돌로 인한 에러이며 아래와 같다.

11:50:03.230 ERROR o.s.b.w.e.tomcat.TomcatStarter :: Error starting Tomcat context. Exception: org.springframework.beans.factory.BeanCreationException. Message: Error creating bean with name 'servletEndpointRegistrar' defined in class path resource [org/springframework/boot/actuate/autoconfigure/endpoint/web/ServletEndpointManagementContextConfiguration$WebMvcServletEndpointManagementContextConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.actuate.endpoint.web.ServletEndpointRegistrar]: Factory method 'servletEndpointRegistrar' threw exception; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'healthEndpoint' defined in class path resource [org/springframework/boot/actuate/autoconfigure/health/HealthEndpointConfiguration.class]: Unsatisfied dependency expressed through method 'healthEndpoint' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'healthIndicatorRegistry' defined in class path resource [org/springframework/boot/actuate/autoconfigure/health/HealthIndicatorAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.actuate.health.HealthIndicatorRegistry]: Factory method 'healthIndicatorRegistry' threw exception; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.actuate.autoconfigure.elasticsearch.ElasticSearchClientHealthIndicatorAutoConfiguration': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'elasticsearchClient' defined in class path resource [org/springframework/boot/autoconfigure/data/elasticsearch/ElasticsearchAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.elasticsearch.client.transport.TransportClient]: Factory method 'elasticsearchClient' threw exception; nested exception is java.lang.IllegalStateException: availableProcessors is already set to [12], rejecting [12]

해당현상이 일어나면 ES Config 설정을 해주면 해결된다.

package com.sds.lego.adminservice.common.config;


import javax.annotation.PostConstruct;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ElasticSearchConfig {
    
    @PostConstruct
    void init() {
        System.setProperty("es.set.netty.runtime.available.processors", "false");
    }
}

 

이래도 안될경우 Application.java 파일에 main에

System.setProperty("es.set.netty.runtime.available.processors", "false");

추가해준다
