java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4] 解决，实测有效

<dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-data-elasticsearchartifactId>
dependency>

<spring-boot.version>2.0.1.RELEASEspring-boot.version>
报错如下:
java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]

解决方法如下：

package net.zjdata.similarity.conf;
import org.springframework.context.annotation.Configuration;
import javax.annotation.PostConstruct;
/**
 * @author lasse
 * @modified by
 * @Date 14:06 2018/7/2
 * @Description ElasticSearch配置
 */
@Configuration
public class ElasticSearchConfig {
    /**
     * 防止netty的bug
     * java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]
     */
    @PostConstruct
    void init() {
        System.setProperty("es.set.netty.runtime.available.processors", "false");
    }
}

如果上面的方法还是解决不了的话，请用下面的方式

@ComponentScan("com.flnet")
@SpringBootApplication
@EnableTransactionManagement
@MapperScan("com.flnet.ms.cms.**.dao")
//@ImportResource({"classpath:disconf.xml"})
public class CmsMediaApplication {

    public static void main(String[] args) {
        /**
         * Springboot整合Elasticsearch 在项目启动前设置一下的属性，防止报错
         * 解决netty冲突后初始化client时还会抛出异常
         * java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]
         */
        System.setProperty("es.set.netty.runtime.available.processors", "false");
        SpringApplication.run(CmsMediaApplication.class, args);
    }
}

在springboot 的启动类里面添加
