From b3271be9188812acdb81470067d6bd01cd5d5fb3 Mon Sep 17 00:00:00 2001 From: Dave Syer Date: Mon, 23 Dec 2024 14:56:57 +0000 Subject: [PATCH] Add explicit support for running on separate port If the user wants a second port for gRPC that should be possible (and was the only way with the old ecosystem projects). This change adds a webflux sample and support for spring.grpc.server.{servlet,reactive}.enabled to be explicitly "false" to disable the embedded services. N.B. embedded services are not yet supported in webflux so the flag has no effect, except to disable gRPC completely if it is "true". --- .../grpc/sample/ListenOnTwoPortsTests.java | 59 ++++ samples/grpc-webflux/README.md | 61 +++++ samples/grpc-webflux/build.gradle | 61 +++++ .../gradle/wrapper/gradle-wrapper.jar | Bin 0 -> 43583 bytes .../gradle/wrapper/gradle-wrapper.properties | 7 + samples/grpc-webflux/gradlew | 252 ++++++++++++++++++ samples/grpc-webflux/gradlew.bat | 94 +++++++ samples/grpc-webflux/pom.xml | 177 ++++++++++++ samples/grpc-webflux/settings.gradle | 8 + .../grpc/sample/GrpcServerApplication.java | 13 + .../grpc/sample/GrpcServerService.java | 51 ++++ .../grpc-webflux/src/main/proto/hello.proto | 23 ++ .../native-image.properties | 2 + .../src/main/resources/application.properties | 1 + .../sample/GrpcServerApplicationTests.java | 59 ++++ samples/pom.xml | 1 + .../modules/ROOT/partials/_configprops.adoc | 54 ++-- .../GrpcServerFactoryAutoConfiguration.java | 70 ++++- 18 files changed, 961 insertions(+), 32 deletions(-) create mode 100644 samples/grpc-tomcat/src/test/java/org/springframework/grpc/sample/ListenOnTwoPortsTests.java create mode 100644 samples/grpc-webflux/README.md create mode 100644 samples/grpc-webflux/build.gradle create mode 100644 samples/grpc-webflux/gradle/wrapper/gradle-wrapper.jar create mode 100644 samples/grpc-webflux/gradle/wrapper/gradle-wrapper.properties create mode 100755 samples/grpc-webflux/gradlew create mode 100644 samples/grpc-webflux/gradlew.bat create mode 100644 samples/grpc-webflux/pom.xml create mode 100644 samples/grpc-webflux/settings.gradle create mode 100644 samples/grpc-webflux/src/main/java/org/springframework/grpc/sample/GrpcServerApplication.java create mode 100644 samples/grpc-webflux/src/main/java/org/springframework/grpc/sample/GrpcServerService.java create mode 100644 samples/grpc-webflux/src/main/proto/hello.proto create mode 100644 samples/grpc-webflux/src/main/resources/META-INF/native-image/org.springframework.samples/grpc-server-sample/native-image.properties create mode 100644 samples/grpc-webflux/src/main/resources/application.properties create mode 100644 samples/grpc-webflux/src/test/java/org/springframework/grpc/sample/GrpcServerApplicationTests.java diff --git a/samples/grpc-tomcat/src/test/java/org/springframework/grpc/sample/ListenOnTwoPortsTests.java b/samples/grpc-tomcat/src/test/java/org/springframework/grpc/sample/ListenOnTwoPortsTests.java new file mode 100644 index 0000000..97dabdb --- /dev/null +++ b/samples/grpc-tomcat/src/test/java/org/springframework/grpc/sample/ListenOnTwoPortsTests.java @@ -0,0 +1,59 @@ +package org.springframework.grpc.sample;
