java.lang.IllegalStateException: availableProcessors is already set to [12], rejecting [12]

srpingboot启动项目会报以下异常，问题原因由于es的netty冲突导致的，问题细节不再赘述

Caused by: java.lang.IllegalStateException: availableProcessors is already set to [12], rejecting [12]at io.netty.util.NettyRuntime$AvailableProcessorsHolder.setAvailableProcessors(NettyRuntime.java:51)at io.netty.util.NettyRuntime.setAvailableProcessors(NettyRuntime.java:87)at org.elasticsearch.transport.netty4.Netty4Utils.setAvailableProcessors(Netty4Utils.java:79)at org.elasticsearch.transport.netty4.Netty4Transport.<init>(Netty4Transport.java:112)at org.elasticsearch.transport.Netty4Plugin.lambda$getTransports$0(Netty4Plugin.java:85)at org.elasticsearch.client.transport.TransportClient.buildTemplate(TransportClient.java:192)at org.elasticsearch.client.transport.TransportClient.<init>(TransportClient.java:288)at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:128)at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:114)at org.elasticsearch.transport.client.PreBuiltTransportClient.<init>(PreBuiltTransportClient.java:104)at org.springframework.data.elasticsearch.client.TransportClientFactoryBean.buildClient(TransportClientFactoryBean.java:85)at org.springframework.data.elasticsearch.client.TransportClientFactoryBean.afterPropertiesSet(TransportClientFactoryBean.java:80)at org.springframework.boot.autoconfigure.data.elasticsearch.ElasticsearchAutoConfiguration.elasticsearchClient(ElasticsearchAutoConfiguration.java:59)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)at java.lang.reflect.Method.invoke(Method.java:498)at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:154)... 70 more

解决方法：

    public static void main(String[] args) {//在main方法里插入下面的代码以解决es的netty冲突问题System.setProperty("es.set.netty.runtime.available.processors", "false");SpringApplication.run(Application.class,args);}

在用junit测试的时候也会报这个异常，解决方法如下：

第一步：


public class TestListener implements TestExecutionListener {@Overridepublic void beforeTestClass(TestContext testContext) throws Exception {//设置环境变量 解决es冲突System.setProperty("es.set.netty.runtime.available.processors", "false");}}

第二步：在springboot的junit测试类头上加上注解

@TestExecutionListeners(listeners = {TestListener.class,DependencyInjectionTestExecutionListener.class})

或者

@TestExecutionListeners(value = { TestListener.class },mergeMode = MergeMode.MERGE_WITH_DEFAULTS)

DependencyInjectionTestExecutionListener类为默认的监听方法，必须加上，否则junit在运行测试用例前不会运行应用。详情参考https://www.baeldung.com/spring-testexecutionlistener

示例如下：

//@TestExecutionListeners(listeners = {TestListener.class,DependencyInjectionTestExecutionListener.class})
@TestExecutionListeners(listeners = {TestListener.class},mergeMode = TestExecutionListeners.MergeMode.MERGE_WITH_DEFAULTS)
@RunWith(SpringRunner.class)
@SpringBootTest
public class ApplationTests {@Testpublic void test(){}
}

这样处理完以后问题就会得到解决。
