我有 2 个 spring boot 应用程序。

应用程序_A 依赖于应用程序_B

实际上每个应用都有主类标记为@SpringBootApplication

application_B 成功启动但 application_A 未启动:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springApplicationAdminRegistrar' defined in class path resource [org/springframework/boot/autoconfigure/admin/SpringApplicationAdminJmxAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.management.InstanceAlreadyExistsException: org.springframework.boot:type=Admin,name=SpringApplication # JMX name of the application admin MBean.

在调试中,我看到 spring 在启动期间执行了两次 org.springframework.boot.autoconfigure.admin.SpringApplicationAdminJmxAutoConfiguration#springApplicationAdminRegistrar 并失败了。

我尝试设置属性:

 spring.application.admin.enabled=false

但这对我没有帮助。

如何避免这种异常?

附言

我找到了这个 https://github.com/spring-projects/spring-boot/issues/6378但是没有解决办法

最佳答案

SpringApplicationAdminJmxAutoConfiguration 的代码如下:

String jmxName = this.environment.getProperty(JMX_NAME_PROPERTY,
DEFAULT_JMX_NAME);
if (this.mbeanExporters != null) { // Make sure to not register that MBean twice
for (MBeanExporter mbeanExporter : this.mbeanExporters) {
mbeanExporter.addExcludedBean(jmxName);
}
}
return new SpringApplicationAdminMXBeanRegistrar(jmxName);

我们有这些常量的地方:

/**
* The property to use to customize the {@code ObjectName} of the application admin
* mbean.
*/
private static final String JMX_NAME_PROPERTY = "spring.application.admin.jmx-name";

/**
* The default {@code ObjectName} of the application admin mbean.
*/
private static final String DEFAULT_JMX_NAME = "org.springframework.boot:type=Admin,name=SpringApplication";

因此,您应该考虑使 jmx-name 对于每个应用程序都是唯一的。我的意思是你需要指定 spring.application.admin.jmx-name 配置属性。

关于java - BeanCreationException : Error creating bean with name 'springApplicationAdminRegistrar' . InstanceAlreadyExistsException,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/48567562/
