grpc Log4j2 example
|
||||
==============================================
|
||||
|
||||
The examples require grpc-java to already be built. You are strongly encouraged
|
||||
to check out a git release tag, since there will already be a build of grpc
|
||||
available. Otherwise you must follow COMPILING.md.
|
||||
|
||||
You may want to read through the
|
||||
[Quick Start Guide](https://grpc.io/docs/quickstart/java.html)
|
||||
before trying out the examples.
|
||||
|
||||
To build the examples,
|
||||
|
||||
1. **[Install gRPC Java library SNAPSHOT locally, including code generation plugin](../../COMPILING.md) (Only need this step for non-released versions, e.g. master HEAD).**
|
||||
|
||||
2. Run in this directory:
|
||||
```
|
||||
$ ../gradlew installDist
|
||||
```
|
||||
|
||||
This creates the scripts `hello-world-server`, `hello-world-client`,
|
||||
`route-guide-server`, and `route-guide-client` in the
|
||||
`build/install/examples/bin/` directory that run the examples. Each
|
||||
example requires the server to be running before starting the client.
|
||||
|
||||
For example, to try the hello world example first run:
|
||||
|
||||
```
|
||||
$ ./build/install/examples-log4j2/bin/hello-world-logcontext-server
|
||||
```
|
||||
|
||||
And in a different terminal window run:
|
||||
|
||||
```
|
||||
$ ./build/install/examples-log4j2/bin/hello-world-logcontext-client
|
||||
```
|
||||
|
||||
That's it!
|
||||
|
||||
Please refer to gRPC Java's [README](../README.md) and
|
||||
[tutorial](https://grpc.io/docs/tutorials/basic/java.html) for more
|
||||
information.
|
||||
|
||||
Unit test examples
|
||||
==============================================
|
||||
|
||||
Examples for unit testing gRPC clients and servers are located in [./src/test](./src/test).
|
||||
|
||||
In general, we DO NOT allow overriding the client stub.
|
||||
We encourage users to leverage `InProcessTransport` as demonstrated in the examples to
|
||||
write unit tests. `InProcessTransport` is light-weight and runs the server
|
||||
and client in the same process without any socket/TCP connection.
|
||||
|
||||
For testing a gRPC client, create the client with a real stub
|
||||
using an InProcessChannelBuilder.java and test it against an InProcessServer.java
|
||||
with a mock/fake service implementation.
|
||||
|
||||
For testing a gRPC server, create the server as an InProcessServer,
|
||||
and test it against a real client stub with an InProcessChannel.
|
||||
|
||||
The gRPC-java library also provides a JUnit rule, GrpcCleanupRule.java, to do the graceful shutdown
|
||||
boilerplate for you.
