elasticSearch availableProcessors is already set to [8], rejecting [8]

使用springboot elasticSearch启动时报

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'apiSearchController': Unsatisfied dependency expressed through field 'compRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'compRepository': Cannot resolve reference to bean 'elasticsearchTemplate' while setting bean property 'elasticsearchOperations'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'elasticsearchTemplate' defined in class path resource [org/springframework/boot/autoconfigure/data/elasticsearch/ElasticsearchDataAutoConfiguration.class]: Unsatisfied dependency expressed through method 'elasticsearchTemplate' 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 [8], rejecting [8]码片

网上查了一下，是elasticSearch和redis共用netty连接，导致连接冲突了，解决办法就是在application启动类上加下面的代码

  public static void main(String[] args){

       //解决netty冲突   
     System.setProperty("es.set.netty.runtime.available.processors", "false");
        SpringApplication.run(Application.class, args);
    }    

但我这样设置了没反应，还是继续报错，最后是在jvm的参数哪里加了下面的代码

-Des.set.netty.runtime.available.processors=false

 这样问题就解决了
