------------------------------
Summary: FallbackPolicy interface support returns an exception
Key: SCB-1304
URL: https://issues.apache.org/jira/browse/SCB-1304
Project: Apache ServiceComb
Issue Type: Bug
Components: Java-Chassis
Reporter: pengliang
Fix For: java-chassis-1.3.0
*WHY*
The service downgrade function opens the
org.apache.servicecomb.bizkeeper.FallbackPolicy interface for users to extend
the downgrade function, but the getFallbackResponse method of the interface
only accepts Invocation, and does not receive exception information, causing
the user to extend the interface to generate a downgrade response without
knowing that the request failed. Due to what kind of abnormality, it may cause
problems such as the retry mechanism does not take effect.
*WHAT*
Satisfying conditions will definitely happen
*HOW*
org.apache.servicecomb.bizkeeper.FallbackPolicyManager.getFallbackResponse(String
type, Throwable error, Invocation invocation) Change the call to the
FallbackPolicy interface, pass in the Throwable
