Question

实际上我正在尝试在云中获取主题 pub/sub。当我发送请求 URL 以获取主题时，我已经使用 restful Web 服务编写了代码，但我遇到了上述错误。经过一番查找，它看起来像 pub/sub 0.17 版本和番石榴 19.o 版本的版本冲突，但我排除了番石榴 19 版本并添加了 18 版本，但同样的异常一次又一次地出现。但是我尝试了所有番石榴版本但没有使用相同的错误。请指导我如何解决以及它为什么会出现。 我要在这里附上我的代码.. 谢谢..

我的代码：

 @Path("/topic")
  public class PubSubServices 
  {

    @Path("/gettopic")
    @GET
    @Produces({ MediaType.TEXT_HTML})
    public Response getTopic() throws Exception {
        String  projectid="My-ProjectID";
        String topicname="my-new-topic";


        System.out.println("Project name is:"+projectid+"  new topic name is:"+topicname);
        try 
        {

        TopicAdminClient topicAdminClient   topicAdminClient=TopicAdminClient.create();
             TopicName topicName = TopicName.create(projectid, topicname);
              Topic topic = topicAdminClient.getTopic(topicName);

        } catch(Exception e)
        {
            e.printStackTrace();
        }

        return Response.status(200).entity(topic.getName();).build();


    }

我创建了 war 文件并上传到 glass fish 服务器。当我发送请求错误时..像 Guava-18 这样的接缝在运行时被旧版本覆盖，而 Guava-18 只在编译任务期间工作。

使用 Main 方法可以正常工作 gud（使用 main 方法测试）

代码：

package com.agro.pubsub.services;
import com.google.cloud.pubsub.spi.v1.TopicAdminClient;
import com.google.pubsub.v1.Topic;
import com.google.pubsub.v1.TopicName;

public class Test {
public static void main(String args[]) throws Exception
{

     try (TopicAdminClient topicAdminClient = TopicAdminClient.create()) {
          TopicName topicName = TopicName.create("My-project-Id", "my-new-topic123");
          Topic topic = topicAdminClient.getTopic(topicName);
    System.out.println(""+topic.getName());
     }

}
}

Answer 1

我找到了解决办法。我将番石榴 19 版本复制到玻璃鱼模块文件夹中 所以这意味着我正在用我的番石榴版本覆盖番石榴

Answer 2

已解决：我将 Guava 依赖项更新到最新版本并解决了问题

 <!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>latest</version>
