业务自己抛出的异常会被框架转换成503吗？

503是标准的HTTP状态码，表示[服务暂时不可用](https://developer.mozilla.org/zh-CN/docs/Web/HTTP/Status/503)。
至于业务自己抛出的异常，默认情况下Java-Chassis是不认识的，会统一转换为590状态码，这个是Java-Chassis自定义的一个HTTP状态码。转换逻辑可以参考代码中的`org.apache.servicecomb.swagger.engine.SwaggerProducerOperation#processException`

> 是不是可以理解为业务自己抛出4XX异常是不会触发隔离机制的呢
你是以何种方式抛出4XX异常的呢？如果这个4XX异常是你们业务定义的异常，那么Java-Chassis默认是无法识别的，实际上会转换为590错误返回，原理方面可以参考一下[异常处理](https://docs.servicecomb.io/java-chassis/zh_CN/general-development/error-handling.html)说明里面关于`org.apache.servicecomb.swagger.invocation.exception.ExceptionToProducerResponseConverter`的说明。
如果在server端 Java-Chassis 确实没有识别你抛出的异常，转换为590错误返回的，那么就不会触发实例隔离了。关于实例隔离等机制的触发逻辑可以参考[这里](https://bbs.huaweicloud.com/forum/thread-12790-1-1.html)
