34176470 opened a new issue #225: dubbo自己扩展的filter在阿里云EDAS环境下未生效？
URL: https://github.com/apache/incubator-dubbo-spring-boot-project/issues/225
自己根据dubbo的filter扩展方式，自己扩展了一个filter
在本机spring boot方式启动时，可以正常进入filter，并执行后续逻辑
在测试环境docker方式启动时，也可以正常进入filter，并执行后续逻辑
但在UAT环境，使用阿里云EDAS环境时，始终进入不了自己扩展的filter
请问这与EDAS环境有关吗？如何解决？
下面是代码：
```
@Activate(group = {Constants.PROVIDER, Constants.CONSUMER}, value = "tracing")
public final class TracingFilter implements Filter {
private static Logger logger = LoggerFactory.getLogger(TracingFilter.class);
Tracer tracer;
TraceContext.Extractor<Map<String, String>> extractor;
TraceContext.Injector<Map<String, String>> injector;
public void setTracing(Tracing tracing) {
tracer = tracing.tracer();
extractor = tracing.propagation().extractor(GETTER);
injector = tracing.propagation().injector(SETTER);
}
@Override
public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException {
logger.info("Dubbo Parameters ==>> " + invoker.getUrl().getParameters());
logger.info("Interface ==>> " + buildSpanName(invoker, invocation));
if (tracer == null) {
logger.info("Tracer is null.");
return invoker.invoke(invocation);
}
//do something...
}
```
