NPE in ConsulDiscoveryClient on startup when used with Zuul #276

Closed rworsnop closed 7 years ago

rworsnop commented 7 years ago

This wasn't happening before I updated to Dalston.M1.

As you can see from the stack trace, it's happening when ConsulDiscoveryClient is used in a Zuul project.

The problem is that localResolver.getPort() is returning null. There's then a NPE in the auto-unboxing when null is compared with 0.

The workaround is to set spring.cloud.consul.discovery.port to the same value as my listening port.

Thanks, pretty hefty refactoring. Glad to knock things like this out.

Setting server.port is a workaround.
