Have you tried the latest with spring boot 3.0 app? Which error do you get?

[credmond-git]

For a very basic example using spring boot 3.0 and io.github.lognet:grpc-spring-boot-starter:4.9.0 i am did not get any issues.
Would you generally consider it safe to use this project with spring boot 3.0?

[jvmlet]

Because looking at release notes and migration guide I don't see something that might prevent using starter developed with 2.7.x API. Also, it's not even sound logical from spring team to drop support of all starters developed so far just because there is new 3.0 runtime and API.
Anyway, I'll run all tests with 3.0 app just to make sure and update release notes with supported SB sversions.

FWIW, I attempted to update my 2.7.x project to 3.0 this week and found that I could get the service to start, but that the GrpcServer didn't appear to start.

I didn't see any errors, it just seemed like the server didn't start. I didn't notice any errors in the logs, but I'll check again tomorrow and post here.

I'm wondering if this issue/workaround in a separate spring boot starter for grpc project might be related? https://github.com/yidongnan/grpc-spring-boot-starter/pull/775#issuecomment-1329023335

I can give specific errors as I find them. The first is SocketUtils is replaced with TestSocketUtils, so trying to write GRPC tests results in:

Caused by: java.lang.NoClassDefFoundError: org/springframework/util/SocketUtils at org.lognet.springboot.grpc.autoconfigure.GRpcServerProperties.lambda$getRunningPort$0(GRpcServerProperties.java:52)

Please try with latest 5.0.0-SNAPSHOT

I think there are some dependencies in 5.0.0-SNAPSHOT that should actually be changed to maven central. I get the following:
`

@ceckhardt, would you please add https://repo.spring.io/milestone/ maven repository to your build and retry.

[jvmlet]

Here is my config

allprojects {
    repositories {
        mavenCentral()
        maven { url 'https://repo.spring.io/release' }
        maven { url "https://jitpack.io" }
        maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
        maven { url 'https://repo.spring.io/snapshot' }
        maven { url "https://repo.spring.io/milestone" }

    }
}

[ceckhardt]

I can confirm all my gRPC spring boot 3 tests are now working with io.github.lognet:grpc-spring-boot-starter:5.0.0-SNAPSHOT
