How to specify gRPC server address target on client side when the service is on format

ANSWER

Answered 2021-Apr-27 at 02:00

It caused by gRPC can't resolve addresss service-name:port;

If you use static, the value must be ip:port; The service-name need to be resolved as ip address;

If you are using register center like consul or eureka etc., you should use discovery:///service-name without specify port.

If you didn't use register center, only end to end with server, replace service-name as a ip like 127.0.0.1 which belong to server;

Or modify host config for parse service-name like below, the file on Linux is /etc/hosts

LogNet gRPC Spring Boot starter - resolve service without service discovery

Asked 2020-Jan-23 at 12:35

I am trying to set up Spring Boot microservices which will communicate via gRPC. I am using the LogNet (https://github.com/LogNet/grpc-spring-boot-starter) Spring Boot starter and am trying to figure out how to have a client/consumer service "connect" to a server/producer service without using service discovery (e.g. Eureka).

I have not been able to find information on how to configure the producer to listen to a port that I specify.

I would then attempt to connect to it from the consumer with code like the following:

Answered 2020-Jan-22 at 22:46

If by producer you mean a gRPC server, then you can configure its port in your application.yml/properties:

Spring Boot gRPC: How to return error code when business error happens?

Asked 2019-Jul-10 at 07:55

I am implementing a gRPC API using LogNet grpc-spring-boot-starter.

I want to return, for instance, an INVALID_ARGUMENT error code when an incorrect argument has been passed.

If I throw a custom exception it ends up with io.grpc.StatusRuntimeException: UNKNOWN.

Q: Is it possible to define some exception handling mechanism so that exceptions of a particular type will always lead to correct gRPC statuses?

There is unfortunately not so much documentation in the project.

...

ANSWER

Answered 2019-Jul-09 at 15:47

gRPC discourages you from throwing an exception in order to communicate that error to the user. This is because it is trivial to accidentally leak information that you may not have considered being sent to a client.

Instead, you are encouraged to pass a StatusException or StatusRuntimeException to streamObserver.onError(Throwable). If you are using exceptions to communicate this information within your own code, you cat put a try-catch within your code and pass the exception to onError(). For example, this might be fair for StatusException, since it is a checked exception.

There is the TransmitStatusRuntimeExceptionInterceptor which will catch exceptions during callbacks and if it is a StatusRuntimeException, close the call with the exception's status. This matches closely to what you're asking for, but it is not enabled by default on purpose.

Very confused: Is spring-boot-starter-web req'd to use Spring Boot with gRPC

Asked 2018-Jun-27 at 21:13

I am trying to use the LogNet/grpc-spring-boot-starter to test using Spring Boot with gRPC. It seems like all the Spring Boot/gRPC examples have the spring-boot-starter-web module included in the build. Is that starter module required in order for the server class annotated with @GRpcService to be always active when started as a Spring Boot jar?

Thanks very much,

Yes. From codenotfound

We include the spring-boot-starter-web dependency which automatically sets up an embedded Apache Tomcat that will host our gRPC service endpoint.

Support

The starter supports the registration of two kinds of interceptors: Global and Per Service. In both cases the interceptor has to implement io.grpc.ServerInterceptor interface. LogInterceptor will be instantiated via spring factory if there is bean of type LogInterceptor, or via no-args constructor otherwise.
