tars Java Codegen Plugin for Protobuf

插件可以和protoc一起生成.proto文件定义的接口；

需要自己编译；

插件编译需要依赖Protobuf

export PROTOBUF_HOME='protobuf安装目录'
export CXXFLAGS='-I$PROTOBUF_HOME/src" LDFLAGS="-L$PROTOBUF_HOME/src/.libs'

System requirement

  • Linux、 Mac OS X with Clang
  • Java 7 or up
  • Protobuf 3.0.0-beta-3 or up

Compiling and testing the codegen

protobuf的编译

git clone https://github.com/google/protobuf.git
./autogen.sh
./configure
make
export PROTOBUF_HOME=`pwd`

插件的编译

git clone [email protected]:scguoi/pb-tars-service-generate-plugin.git
cd pb-tars-service-generate-plugin
export CXXFLAGS="-I$PROTOBUF_HOME/src" LDFLAGS="-L$PROTOBUF_HOME/src/.libs"
./gradlew java_pluginExecutable

Usage

Mac

单文件

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:$PROTOBUF_HOME/src/.libs
cd usage/single
$PROTOBUF_HOME/src/.libs/protoc --plugin=protoc-gen-tars-java=../../build/exe/java_plugin/protoc-gen-tars-java --tars-java_out=./ --java_out=./ flight.proto
