QUESTION
We are using grpc spring boot starter on our Java application service in order to establish a connection to another 'server' service, so I define in the application.properties
the following address:
ANSWER
Answered 2021-Apr-27 at 02:00It 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

I've created a simple test gRPC server(Java, Spring) to test the technology.
When trying to call a function from the server I am getting an error { "error": "2 UNKNOWN: Stream removed" }
Inside the application, no stack trace is printed, I can't catch the program execution using breakpoint invisible for me code

I have a Spring Boot micro-service which listens through GRPC using LogNet/grpc-spring-boot-starter
By default GRPC payload maximum size is 4MB. At client side, it's easy to set the response payload size, but I want to increase the request size at the server side.

I'm new to gRpc, I'm trying to use it between a Java 11(Spring Boot 2) server and a Java 8 (Spring Boot 1.5) client using gRpc 1.27.1 and protobuf 3.11.
Here is my setup:
I have data model library with just 1 proto definition file and maven files to generate java source code that is shared between the client and the server

QUESTION
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 22:46If by producer you mean a gRPC server, then you can configure its port in your application.yml/properties

QUESTION
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 15:47gRPC 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.

I want to create a Reactor Flux from a gRPC StreamObserver. This needs to be done as long as StreamObserver does not implement the respective interfaces natively (see e.g. this issue).
What I came up with is roughly like the following:

QUESTION
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,
Steve
...ANSWER
Answered 2018-Jun-27 at 21:13Yes. 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.
