4 years ago 在biz里直接使用
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
<version>2.1.0.RELEASE</version>
</dependency>可以正常启动... 打断点到cat.class的if里就走不下去了.... private static void initializeInternal() { validate(); if (isEnabled()) { try { if (!init) { synchronized(instance) { if (!init) { producer = DefaultMessageProducer.getInstance(); } } } } catch (Exception var5) { errorHandler(var5); disable(); } }
}
