创建名为 springApplicationAdminRegistrar 的 bean 时出错

Question

在将项目从 Spring Boot 版本从 1.2.3.RELEASE 迁移到 1.3.0.RELEASE 后，我开始遇到异常。

创建名为“springApplicationAdminRegistrar”的 bean 时出错 在类路径资源中定义 [org/springframework/boot/autoconfigure/admin/SpringApplicationAdminJmxAutoConfiguration.class]： 调用 init 方法失败；嵌套异常是 javax.management.InstanceAlreadyExistsException： org.springframework.boot:type=Admin,name=SpringApplication

围绕此错误的堆栈跟踪是：

有调试这个问题的指针吗？

上下文是从用于获取 bean 的代码中手动加载（Java 代码），删除它解决了问题。 但是我的问题已经解决了，但仍然不确定它是如何与最新版本的 spring boot 一起工作的。
