设置唯一的 Bean 名称 javax.management.InstanceAlreadyExistsExceptio

Question

当我使用 Spring AMQP 部署 2 个包时，我在以下代码中收到 JMX 错误：

@Bean
public CachingConnectionFactory connectionFactory() {
CachingConnectionFactory connectionFactory = new CachingConnectionFactory(HOST);
connectionFactory.setBeanName("Test_123");
return connectionFactory;
}

我错误Caused by: javax.management.InstanceAlreadyExistsException: org.springframework.amqp.rabbit.connection:name=connectionFactory,type=CachingConnectionFactory

如何为连接工厂设置唯一名称？

编辑：

我还尝试将 application.properties 放在 src/main/java/resources 这个配置下：

spring.jmx.enabled=false
spring.datasource.jmx-enabled=false
spring.jmx.default-domain=ssds # JMX domain name.
spring.jmx.server=apiServer # MBeanServer bean name.
management.metrics.export.jmx.domain=metccriddcs # Metrics JMX domain name.
management.metrics.export.jmx.enabled=false # Whether exporting of metrics to JMX is enabled.
management.endpoints.jmx.exposure.exclude=*

但是我得到了同样的错误。

解决方案：

... implements ObjectNamingStrategy {
@Override
public ObjectName getObjectName(Object managedBean, String beanKey) throws MalformedObjectNameException {
Class managedClass = AopUtils.getTargetClass(managedBean);
String domain = ClassUtils.getPackageName(managedClass);
Hashtable<String, String> properties = new Hashtable<>();
properties.put("type", ClassUtils.getShortName(managedClass));
properties.put("name", "asdsdsd");
// ensure the application name is included as a property in the object name
properties.put("app", "api");
return ObjectNameManager.getInstance(domain, properties);
}
}
