我将项目从Spring Boot版本从1.2.3.RELEASE迁移到1.3.0.RELEASE后，我开始遇到异常。
使用名称＆＃39; springApplicationAdminRegistrar＆＃39;创建bean时出错。 在类路径资源中定义 [组织/ springframework的的/ boot /自动配置/管理/ SpringApplicationAdminJmxAutoConfiguration.class]： 调用init方法失败;嵌套异常是 javax.management.InstanceAlreadyExistsException： org.springframework.boot：类型=管理员，名字= SpringApplication
围绕此错误的Stacktrace是：

任何指向调试此问题的指针？
答案 0 :(得分：0)
上下文是从用于获取bean的代码手动加载（Java代码），删除哪个解决了问题。 但是我的问题已经解决了，但仍然不确定它是如何使用最新版本的spring boot。
