Amazon web services 我可以通过sqldeveloper连接到AWS RDS，但可以'；Java应用程序的t

我可以用sqldeveloper连接到AWS RDS，但不能用java应用程序（java源代码或jsp）连接到AWS RDS

当我尝试访问RDS时，会出现如下错误：

coyote.AbstractProtocol.init Initializing ProtocolHandler ["http-nio-8080"]

但URL的值与我尝试使用sqldeveloper时的值相同

有什么问题吗

请开导我，因为我已经为此忍受了大约一周的痛苦！：（

我不确定您的应用程序是如何设置的，但我使用的是Maven&Spring Boot，它的工作原理如下：

我主要遵循本指南，忽略了.sql文件、thymeleaf UI、“model.addAttribute（“cities”，cities）；”部分和html文件：

我的application.properties文件如下所示

postgres.comment.aa=https://zetcode.com/springboot/postgresql/
spring.main.banner-mode=off
logging.level.org.springframework=ERROR

spring.jpa.hibernate.ddl-auto=none

spring.datasource.initialization-mode=always
spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://your-rds-url-here.us-east-1.rds.amazonaws.com:yourDbPortHere/postgres
spring.datasource.username=postgres
spring.datasource.password=<your db password here>

spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

多亏了这一点，架构的答案如下：

这些其他夫妇的联系也有帮助

它是立即失败，还是需要一段时间才能失败？@JohnRotenstein它立即失败。因为在我尝试之后，我立即检查徽标。消息已经存在。用户名和密码进入属性，而不是url

spring.datasource.url=jdbc:postgresql://your-rds-url-here.us-east-1.rds.amazonaws.com:yourDbPortHere/postgres?currentSchema=users
