我在启动java应用程序时遇到以下错误。
在启动应用程序之前，我需要将一些与hadoop相关的目录导出到类路径以使其正常工作（我不能跳过这一步），我得到以下错误。
原因：java.lang.linkageerror:classcastexception:正在尝试castjar:file：/usr/hdp/3.0.0.0-1634/hadoop/lib/jsr311-api-1.1.1.jar/javax/ws/rs/ext/runtimedelegate.class到jar:file：/tmp/blobstore-634df1c1-ffc8-4610-86af-8f39b33e4250/job\u ac11246bea2bb31008c1a78212357514/blob\u p-79f2d3193313ea987c15b4b28411db0fc2aa436c-f858cb54126b6d546c01ed453bf106/javax.ws.rs.ext.runtimedelegate.finddelegate（runtimedelegate）中的javax/ws/rs/ext/runtimedelegate.class。java:146)在javax.ws.rs.ext.runtimedelegate.getinstance（runtimedelegate。java:120)在javax.ws.rs.core.uribuilder.newinstance（uribuilder。java:95)在javax.ws.rs.core.uribuilder.fromuri（uribuilder。java:119)在org.glassfish.jersey.client.jerseywebtarget.（jerseywebtarget。java:71)在org.glassfish.jersey.client.jerseyclient.target（jerseyclient。java:290)在org.glassfish.jersey.client.jerseyclient.target（jerseyclient。java:76)在com.hortonworks.registries.schemaregistry.client.schemaregistryclient.lambda$currentschemaregistrytargets$0（schemaregistryclient）。java:293)在java.util.concurrent.concurrenthashmap.computeifabsent（concurrenthashmap。java:1660)在com.hortonworks.registries.schemaregistry.client.schemaregistryclient.currentschemaregistrytargets（schemaregistryclient。java:293)在com.hortonworks.registries.schemaregistry.client.schemaregistryclient.getsupportedschemaproviders（schemaregistryclient）上。java:384)在com.hortonworks.registries.schemaregistry.client.schemaregistryclient.getdefaultdeserializer（schemaregistryclient）。java:969)在schemaservice.initdeserializer（schemaservice。java:47)在schemaservice.deserialize（schemaservice。java:38)在org.apache.flink.streaming.connectors.kafka.internals.kafkadeserializationschemawrapper.deserialize（kafkadeserializationschemawrapper。java:45)在org.apache.flink.streaming.connectors.kafka.internal.kafkafetcher.runfetchloop（kafkafetcher。java:140)在org.apache.flink.streaming.connectors.kafka.flinkkafcumerbase.run（flinkkafcumerbase。java:712)在org.apache.flink.streaming.api.operators.streamsource.run（streamsource。java:93)在org.apache.flink.streaming.api.operators.streamsource.run（streamsource。java:57)在org.apache.flink.streaming.runtime.tasks.sourcestreamtask.run（sourcestreamtask）。java:97)在org.apache.flink.streaming.runtime.tasks.streamtask.invoke（streamtask。java:302)在org.apache.flink.runtime.taskmanager.task.run（task。java:711)在java.lang.thread.run（线程。java:745)
在做了一些研究之后，我发现程序试图使用的类存在于两个不同的jar文件中：
第一个是对maven应用程序（javax.ws.rs.jar）上的库的一种可传递依赖
第二个是一个jar，位于hortonworks的hadoop目录中，我需要将它导出到类路径中，以使应用程序正常工作（jsr311-api-1.1.1.jar）
因此，我需要以某种方式告诉程序，应该使用打包在应用程序jar中的maven依赖项，而不是位于类路径上的jar（javax.ws.rs.jar），而不删除这个jar，因为它是我的大数据集群安装的一部分，我不能在类路径中使用这些jar。
有什么想法吗？
导致问题的pom.xml依赖项：

<dependency>
    <groupId>com.hortonworks.registries</groupId>
    <artifactId>schema-registry-client</artifactId>
    <version>${schema.registry.version}</version>
</dependency>

按热度按时间

如果解决linkageerror时类名相同，则可以这样导入。
所以我们有两个名字相同但包不同的类
头等舱

package com.bbc.config;

public class Test1 {
 }

二等舱

package com.bbc.domain;

public class Test1 {
}

还有主课

package com.bbc.mainclass;
import com.bbc.config.Test1;

public class Main {
  public static void main(String[] args) {

  // this will import from config      
  Test1 test1 = new Test1(); // this will import from Test1

  // this will import from domain       
  com.bbc.domain.Test1 test11 = new com.bbc.domain.Test1();

  }
}

我将这些jar添加到具有这些版本的类路径上。建造并运行。我找不到任何理由。
