那些遇到过的问题

在tomcat容器中具有多个Web应用程序的Spring Boot执行程序抛出javax.management.InstanceAlreadyExistsException异常

sat*_*sat 29 spring tomcat spring-boot

我在一个tomcat容器(不是嵌入式 - 只是独立的tomcat容器)中运行多个spring启动应用程序.但是,在启动Web应用程序时,它给出了以下例外情况.它不会影响任何Web应用程序的功能,但仍然是我想要解决的一个干净的启动.

任何有关如何解决此问题的帮助非常感谢.

使用Spring Boot 1.1.7

默认情况下,所有端点都在域下注册org.springboot并具有默认名称.这些可以通过设置endpoints.jmx.*属性来覆盖.看到这里.

您可能希望更改每个应用程序的域或将其设置endpoints.jmx.unique-names为true.

  • 请参阅下面@bigbadmouse的答案,以获得有关其工作原理的更详细说明.它帮助了我.在我的例子中,我在尝试运行单元测试时得到了"InstanceAlreadyExistsException",所以我将`spring.jmx.enabled = false`行添加到我的`src/test/resources/application.properties`文件中. (2认同)
