当我尝试示例化awssnsclient时,我得到了一个错误类定义not found。此代码没有在aws lambda及其本地系统中运行。这是我的java代码
18-> AmazonSNSClient snsClient = new AmazonSNSClient(credentials);
snsClient.setRegion(Region.getRegion(Regions.));
ObjectMapper Obj = new ObjectMapper();
PublishRequest publishRequest = new PublishRequest();
publishRequest.setTargetArn("");
publishRequest.setMessage("");
PublishResult publishResponse = snsClient.publish(publishRequest);

我已经尽我所能检查了您的java代码片段,我注意到了两个问题:
(i)以下行不完整:
应改为:
(ii)以下声明被否决:
以及
相反,应按以下方式创建aws服务客户端:
如果您使用的是凭据文件,则可以使用以下选项:
如果要使用instanceprofilecredentialprovider,则可以使用以下选项:
更多信息可以在aws java开发者指南中找到
希望这有帮助!
