在启动类增加

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

如下所示

@SpringBootApplication
public class FrontApplication {

public static void main(String\[\] args) {

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

}
