Tomcat 在AWS上使用ElastiCache和ElasticBeanstalk配置Redis
我有一个Tomcat+Redis应用程序在Elastic Beanstalk上运行。在我的代码中，我使用Tomcat 在AWS上使用ElastiCache和ElasticBeanstalk配置Redis,tomcat,amazon-web-services,redis,amazon-elastic-beanstalk,Tomcat,Amazon Web Services,Redis,Amazon Elastic Beanstalk,我有一个Tomcat+Redis应用程序在Elastic Beanstalk上运行。在我的代码中，我使用 pool = new JedisPool(new JedisPoolConfig(), "localhost"); 当然，在生产环境中，我不能使用我通读过的“localhost”，也不能使用自动发现来处理代码，但这似乎只适用于Memcached 有人用Beanstalk配置了Redis ElastiCache集群吗。您从哪里获得要使用的DNS地址而不是“localhost”？恐怕您无法轻松
pool = new JedisPool(new JedisPoolConfig(), "localhost");
有人用Beanstalk配置了Redis ElastiCache集群吗。您从哪里获得要使用的DNS地址而不是“localhost”？恐怕您无法轻松获得AWS ElastiCache端点（例如：环境变量） 从AWS文档中，我们可以了解NodeJS+ElastiCache Memcache解决方案。在根项目中创建以下两个
