I have a scenario in Zuul where the service that the URL is routed too might be down . So the reponse body gets thrown with 500 HTTP Status and ZuulException in the JSON body response.
{
"timestamp": 1459973637928,
"status": 500,
"error": "Internal Server Error",
"exception": "com.netflix.zuul.exception.ZuulException",
"message": "Forwarding error"
}
All I want to do is to customise or remove the JSON response and maybe change the HTTP status Code.
I tried to create a exception Handler with @ControllerAdvice but the exception is not grabbed by the handler.
UPDATES:
So I extended the Zuul Filter I can see it getting into the run method after the error has been executed how do i change the response then. Below is what i got so far. I read somewhere about SendErrorFilter but how do i implement that and what does it do?
public class CustomFilter extends ZuulFilter {
@Override
public String filterType() {
return "post";
}
@Override
public int filterOrder() {
return 1;
}
@Override
public boolean shouldFilter() {
return true;
}
@Override
public Object run() {
final RequestContext ctx = RequestContext.getCurrentContext();
final HttpServletResponse response = ctx.getResponse();
if (HttpStatus.INTERNAL_SERVER_ERROR.value() == ctx.getResponse().getStatus()) {
try {
response.sendError(404, "Error Error"); //trying to change the response will need to throw a JSON body.
} catch (final IOException e) {
e.printStackTrace();
} ;
}
return null;
}
Added this to the class that has @EnableZuulProxy
@Bean
public CustomFilter customFilter() {
return new CustomFilter();
}
