其实我正在尝试在cloud pub / sub中获取主题。当我发送请求URL以获取上述错误的主题时,我已经用宁静的Web服务编写了代码。经过一些查询后,它会像pub / sub 0.17版本和番石榴19.o版本的版本冲突一样,但我排除了guava 19版本并添加了18个版本,但同样的异常会一次又一次地出现。但是我尝试了所有番石榴版本,但没有使用相同的错误即将到来。请指导我如何解决以及它为什么会来。 我要在这里附上我的代码.. 感谢..
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,我上传到玻璃鱼服务器。当我发送请求错误时...像Guava-18这样的接口在运行时被旧版本覆盖,而Guava-18仅在编译任务期间工作。
使用主要方法工作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());
}
}
}

问题是,当我使用带有jersey的restful web服务编写代码时,我遇到了上述错误,我无法找到解决方案。 有什么解决方案吗?
答案 0 :(得分:0)
我得到了解决方案。我将番石榴19版复制到玻璃鱼模块文件夹中 所以这意味着我用我的番石榴版本重写番石榴
答案 1 :(得分:0)
解决:我将Guava依赖关系更新为最新版本,它解决了问题
