Annotation to specify multiple UnexpectedResponseExceptionType

Is your feature request related to a problem? Please describe. The REST Proxy should be able to throw richer exception depending on the error code returned by service.

Describe the solution you’d like Define an annotation, that can be used to define multiple exception types and map each exception type to error codes.

An example usage looks like:

@UnexpectedResponseExceptionTypes({ @UnexpectedResponseExceptionTypes.Type(code = {333}, value = Exception333.class), @UnexpectedResponseExceptionTypes.Type(code = {345, 346}, value = RestException.class), @UnexpectedResponseExceptionTypes.Type(value = ServiceRequestException.class) })

The annotation looks like:

public @interface UnexpectedResponseExceptionTypes { public Type[] value();

public @interface Type { public int[] code() default { }; public Class<?> value(); } }

The above grouping is needed only in java 7 and below, java 8+ supports repeated annotations. Switching to the experience that @JonathanGiles originally proposed.

Reference: see this discussion.

Example usage:

@UnexpectedResponseExceptionType(code = {333}, value = Exception333.class),
@UnexpectedResponseExceptionType(code = {345, 346}, value = RestException.class),
@UnexpectedResponseExceptionType(value = ServiceRequestException.class)

Annotation definition:

public @interface UnexpectedResponseExceptionType {
    public Class<?> value();
    public int[] code() default { };
}
