spring - WebSphereMBeanServerFactoryBean 的 NullPointerException

Question

我的类路径上有一些 Websphere jar，导致 Spring AnnotationMBeanExporter 出现问题

我可以告诉 Spring 排除 org.springframework.jmx.support.WebSphereMBeanServerFactoryBean 或忽略 com.ibm 包下的 MBean 吗？

完全异常:

spring-boot 1.3.5.RELEASE

Answer 1

自己创建MBeanServer，这将禁止根据您的环境查找最佳选项的任何尝试。我想以下应该有效

@Bean
public MBeanServer mbeanServer() {
  MBeanServerFactoryBean factory = new MBeanServerFactoryBean();
  factory.setLocateExistingServerIfPossible(true);
  factory.afterPropertiesSet();
  return factory.getObject();
}
