Spring 云：触发/刷新时出现 InstanceAlreadyExistsException
Spring Cloud: InstanceAlreadyExistsException when /refresh is triggered
我正在构建一个利用 JdbcEnvironmentRepository 的示例应用程序。我提供了一个 BootstrapConfiguration class:
@EnableAutoConfiguration
@AutoConfigureAfter(JdbcTemplateAutoConfiguration.class)
public class CloudBootstrapConfiguration {
}
然后在 spring.factories:
中指定
org.springframework.cloud.bootstrap.BootstrapConfiguration=\
rz.demo.jdbc.repo.factory.CloudBootstrapConfiguration
应用程序成功启动，并按预期从数据库中检索属性。
然而，当我向 /refresh 发出 POST 请求时，发生了错误
Caused by: javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Admin,name=SpringApplication
可以在 Github.
上找到应用程序示例
完整的堆栈跟踪如下：

我将 spring.factories 的内容更改为
后问题得到解决org.springframework.cloud.bootstrap.BootstrapConfiguration=\
org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,\
org.springframework.boot.autoconfigure.jdbc.JdbcTemplateAutoConfiguration
并删除 class CloudBootstrapConfiguration.
