liubao updated SCB-425:
-----------------------
Fix Version/s: (was: java-chassis-1.0.0-m2)
> Add an easier way to read configurations
> ----------------------------------------
>
> Key: SCB-425
> URL: https://issues.apache.org/jira/browse/SCB-425
> Project: Apache ServiceComb
> Issue Type: New Feature
> Components: Java-Chassis
> Reporter: liubao
> Priority: Major
>
> Background:
> Read configurations for microservice or operation is quite common in code,
> e.g.
> {code:java}
> config = CONSUMER_FAULTINJECTION + serviceName + ".schemas." + schema + "."
> + CONSUMER_FAULTINJECTION_POLICY_PROTOCOLS +
> invocation.getTransport().getName() + "." + key;
> value = getConfigValue(config);
> if ((value != FAULT_INJECTION_DEFAULT_VALUE)) {
> return value;
> }
> config = CONSUMER_FAULTINJECTION + serviceName + "." +
> CONSUMER_FAULTINJECTION_POLICY_PROTOCOLS
> + invocation.getTransport().getName() + "." + key;
> value = getConfigValue(config);
> if ((value != FAULT_INJECTION_DEFAULT_VALUE)) {
> return value;
> }
> config = CONSUMER_FAULTINJECTION_GLOBAL +
> CONSUMER_FAULTINJECTION_POLICY_PROTOCOLS
> + invocation.getTransport().getName() + "." + key;
> {code}
> This code is very long and add callbacks if hard for user code.
>
> Suggestions:
> We need a easier way to read configurations, code snippets:
> {code:java}
> @Configuration(name="cse.myconfiguration")
> class MyConfiguration
> {
> @Configuration(name="prop1")
> String prop1;
> @Configuration(name="prop2")
> String prop2;
> }
> MyConfiguration configuration =
> ConfigurationFactory.getReference(invocation.getQualifiedMicroserviceName()){code}
>
