I am using feign client to call other microservice but when the calling service is down feign should give the exception of "503 service unavailable" but it giving exceptionCode = 0 with the message "Loadbalance does not have an available server to the client".
If the service is down, I want to hit the ErrorDecoder and retry the call, but Feign is giving 0 exception codes, so it cannot reach the error decoder.
What I am missing?
Check your service is registered with the discovery server.
Check your spring properties 'spring-application-name' is equal to feignClient annotation's value properties

My spring boot app has a feign client that POST a payload to external endpoint.
There is requirement to audit all the calls, especially when any errors occurs in calling the endpoint (connection, unauthorized etc), after retry are exhausted. To audit,
need some information from original payload
http status
underlying exception message,
backup original payload for reference
endpoint
I tried below approaches (for error handling), but still unable to find a solution that covers all above
feign Fallbackfactory - it has handle to exception, but unable to effectively capture feign response/original payload
fallbackMethod with resilence4j - here i get access to original payload and exception, but again unable to capture actual response status (401, 503 etc)
CustomErrorDecoder - Here able to get access to feign Response, but then have to map response body (any request body/payload). Also have to map exception
Appreciate any suggestion/ advise?
I'm getting deprecated message for the bean Wss4jSecurityInterceptor. I'm using >spring-boot-starter-ws(1.4.7-RELEASE). spring-ws-security(2.4.4-RELEASE), org.apache.ws.security wss4j (1.6.9).
How to add the username token to consume SOAP services using Spring WebService Template ?
Sorry..Silly error..Need to upgrade to "org.springframework.ws.soap.security.wss4j2.Wss4jSecurityInterceptor;"...wss4j2 instead of wss4j.
However still Null pointer exception " Received Fault message for request Exception=null.
Settled. The application message exception object isn't extracted properly from the SoapFaultClientException.. e.getSoapFault().getFaultDetail()
JHipster / Spring boot provides a nice endpoint /management/health, where it aggregates health information for subsystems like db, disk, and mail.
Unfortunately, when the connection to the mail server fails, the whole endpoint fails. So you do not get information what has failed.
I get a strack trace like this:
o.s.b.a.health.MailHealthIndicator : Health check failed
com.sun.mail.util.MailConnectException: Couldn't connect to host, port: XXXX, NNNN25025; timeout -1
...

This is spring boot 1.5.9
Where should I fix this, so that the exception is catched and instead a an error status is returned?
You have to turn on your SMTP server or disable checks to it.
To disable checks to SMTP server:
management.health.mail.enabled=false
To disable checks to all server:
management.health.defaults.enabled=false

I believe you can handle this error with the ExceptionHandler for 1.5.9 version of Spring Boot since the newer version there is no such problem:
#ControllerAdvice
public class ExceptionController {
#ExceptionHandler(MailConnectException.class)
public ResponseEntity<?> mailExceptionHandler(MailConnectException e) {
// Do your treatment ...
} ...
}
AM trying to invoke a spring boot microservice from another application.
Here is my Server code, if any exception occurs
return ResponseEntity.status(HttpStatus.FORBIDDEN)
.body(new com.test.models.ResponseEntity("Tenant details
not found"));
Here is my client code,
ResponseEntity<Object> uploadResponse =
restTemplate.exchange("http://TESTAPPLICATION/v1/object",
HttpMethod.POST, requestEntity, Object.class);
Am getting a response as
Caused by: org.springframework.web.client.HttpClientErrorException: 403 null
If I hit my endpoint from PostMan, am getting proper response message.
But from my client-side application am getting response message as null. Please let me know what is going wrong.
UPDATE:
Screenshot.
Client Responds with INTERNAL_SERVER_ERROR. But from my server iam responding 403.
I have hosted 3 microservices in PCF. One is a eureka server and the other 2 are client and service microservices. The client is supposed to call the service through a rest template call and service will return a string.
I have 1 instance each of the eureka server and the client and 2 instances of the service.
I can see both my client and service registered in the Eureka dashboard. But when i try to access the service from the client[Using a rest template call] I get - 'No instances available for the [service name]'
But if i access my service directly from browser then its works fine and returns the string. But the same URL if called from a rest template returns the exception i mentioned above.
Any suggestions will help
Did you add the #LoadBalance on restTemplate bean.
#Bean
#LoadBalanced
public RestTemplate restTemplate() {
return new RestTemplate();
}
And when calling service you have to use the service name as below.
