Still a release candidate (not yet GA), but seems to work, so we'll
try and update before Spring Cloud is released again.
Fixes gh-546, fixes gh-567, fixes gh-553 (probably)
Other Ribbon clients in Spring Cloud use a ServerIntrospector
to check if the Server wanted to be secure. This change levels things
up (and makes the Spring Feign Client a lit easier to customize).
See gh-414
Most clients send "Transfer-Encoding: chunked" so this isn't often
an issue, but if they don't (e.g. if you use "-H Expect:" with
curl) then it's not a great idea to slurp it all into memory.
Fixes gh-563
When using Ribbon the hystrix config and metrics are namespaced
as "RibbonCommand" (via the group key). the command key can then be
serviceId, making it easier to remember how to configure
Ribbon and Hystrix.
Fixes gh-329
There are usually some hints available, especially if the Server
came from Eureka. Unfortunately Server on it's own doesn't contain
enough information (why?), but as a fallback we can guess that
anyone using port 443 is secure.
Fixes gh-459
Remove Servo from EurekaHealthIndicator.
Remove custom DataCenterInfo.
EurekaInstanceConfig.SID is now used as eureka id.
EurekaInstanceConfigBean.getSID falls back to metadataMap.instanceId for
backwards compatibility.
And also when using eureka-first for discovering config server.
The EurekaClient is very rigid and initializes itself, registering
with the remote service on instantiation. Hance it needs to be
in @RefreshScope for it to be properly refreshable. Doing that
leads to a sequence of other changes (e.g. to account for the
fact that there is no @RefreshScope in bootstrap context).
Fixes gh-551
When the parent (bootstrap) context registers the app as well as consuming
the registry it causes problems, e.g. when you refresh that context is
re-created and destroyed, which tends to unregister the app and it's hard
to get it back. It is simpler if the parent context use eureka read-only.
To ensure this we have to remove the @EnableDiscoveryClient from the
bootstrap context.
Tested with vanilla config server and eureka with the 'eureka-first'
sample and the 'zuul-proxy-eureka' sample.
Fixes gh-421
Reverts part of a change made for gh-349 and rationalizes a bit of the
Eureka configuration. The Eureka client cannot be shutdown without
attempting to restart it (but there isn't an obvious public API for
that), so it's better not to shut it down at all.
