I have two Spring Boot REST application they talk with each other.
ProjectA, getTest rest service sometimes it takes a minute. It calls from projectB.
@PostMapping(value = "/test")
public ResponseEntity<Map<byte[], List<String>>> getTest(
@RequestBody ObjectDTO configDto) {
try {
HashMap<byte[], List<String>> testMap =
serviceImpl.test(configDto);
if (!testMap.isEmpty())
return new ResponseEntity<>(testMap, HttpStatus.CREATED);
else return new ResponseEntity<>(testMap, HttpStatus.NO_CONTENT);
} catch (Exception e) {
return ResponseEntity.badRequest().build();
}
}
ProjectB which calls the API above.
@PostMapping(value = "/getTest")
@Async
public ResponseEntity<Map<byte[], List<String>>> getTest(
@RequestBody Config config) {
try {
Map<byte[], List<String>> val = serviceImpl.testConfig(config);
return new ResponseEntity<>(val, HttpStatus.CREATED);
} catch (Exception e) {
return ResponseEntity.badRequest().build();
}
}
It works locally but when I run on prod it always returns after 6.2s:
upstream request timeout
I have already increased the timeout on the properties with the config below on Project B, but did not work.
server.tomcat.connection-timeout=120000
spring.mvc.async.request-timeout=120000
so the question is how to fix a 504 Gateway Timeout Error
Update:
Fixed by setting a timeout on ambassador .yaml file below.
apiVersion: getambassador.io/v2
kind: Mapping
metadata:
name: ambassador-header-mapping
namespace: x
spec:
prefix: /
timeout_ms: 60000
service: dummyservice:8080
ambassador_id: ambassador-x
headers:
X-Forwarded-Proto: https
Host: dummyhost
