# eRPC Java Infrastructure
|
|
|
|
This folder contains the Java implementation of the eRPC infrastructure.
|
|
|
|
## Contents
|
|
|
|
- [/src/main/java/io/github/embeddedrpc/erpc](./src/main/java/io/github/embeddedrpc/erpc) - Java package containing eRPC infrastructure.
|
|
- [pom.xml](./pom.xml) - Maven config file.
|
|
- [checkstyle.xml](./checkstyle.xml) - Check style config file.
|
|
|
|
## Prerequisites
|
|
|
|
- [Java 21 SDK](https://jdk.java.net/21/)
|
|
- [Maven 3.9.5](https://maven.apache.org/download.cgi)
|
|
|
|
To check that all the prerequisites are correctly installed, run `mvn -v`. You should get something like this:
|
|
|
|
```
|
|
Apache Maven 3.9.5 (***)
|
|
Maven home: c:\Program Files\maven\apache-maven-3.9.5
|
|
Java version: 21, vendor: Oracle Corporation, runtime: c:\Program Files\Java\jdk-21
|
|
Default locale: en_US, platform encoding: UTF-8
|
|
OS name: "***", version: "***", arch: "***", family: "***"
|
|
```
|
|
|
|
- If `mvn -v` fails, check that you have added maven to the `PATH` variable.
|
|
- If you do not see the correct Java version, check that you have set the `JAVA_HOME` and `PATH` variables correctly.
|
|
|
|
|
|
## Installation
|
|
|
|
1. Run `mvn install` to download all dependencies and install eRPC to local maven repository.
|
|
|
|
## Usage
|
|
|
|
### Client
|
|
|
|
```Java
|
|
import io.github.embeddedrpc.erpc.auxiliary.Reference;
|
|
import io.github.embeddedrpc.erpc.client.ClientManager;
|
|
import io.github.embeddedrpc.erpc.codec.BasicCodecFactory;
|
|
import io.github.embeddedrpc.erpc.transport.TCPTransport;
|
|
import io.github.embeddedrpc.erpc.transport.Transport;
|
|
|
|
import com.example.app.client.MyTestClient;
|
|
|
|
public class Main {
|
|
public static void main(String[] args) {
|
|
Transport transport = new TCPTransport("localhost", 40);
|
|
//Transport transport = new SerialTransport("COM4", 115200);
|
|
|
|
ClientManager clientManager = new ClientManager(transport, new BasicCodecFactory());
|
|
MyTestClient client = new MyTestClient(clientManager);
|
|
|
|
Reference<String> out;
|
|
int result;
|
|
|
|
result = client.foo(42, 8);
|
|
client.boo("John", out);
|
|
}
|
|
}
|
|
```
|
|
|
|
### Server
|
|
#### Main.java
|
|
```Java
|
|
import io.github.embeddedrpc.erpc.server.Server;
|
|
import io.github.embeddedrpc.erpc.server.SimpleServer;
|
|
import io.github.embeddedrpc.erpc.codec.BasicCodecFactory;
|
|
import io.github.embeddedrpc.erpc.transport.TCPTransport;
|
|
import io.github.embeddedrpc.erpc.transport.Transport;
|
|
|
|
import com.example.app.MyTestService;
|
|
|
|
public class Main {
|
|
public static void main(String[] args) {
|
|
Transport transport = new TCPTransport("localhost", 40);
|
|
//Transport transport = new SerialTransport("COM4", 115200);
|
|
|
|
Server server = new SimpleServer(transport, new BasicCodecFactory());
|
|
|
|
server.addService(new MyTestService());
|
|
|
|
server.run();
|
|
}
|
|
}
|
|
```
|
|
#### MyTestService.java
|
|
|
|
```Java
|
|
import io.github.embeddedrpc.erpc.auxiliary.Reference;
|
|
import com.example.app.server.AbstractMyTestService;
|
|
|
|
public class MyTestService extends AbstractMyTestService {
|
|
@Override
|
|
public int foo(int a, int b) {
|
|
return a + b;
|
|
}
|
|
|
|
@Override
|
|
public void boo(String in, Reference<String> out) {
|
|
out.set("Hello " + in);
|
|
}
|
|
}
|
|
