Can be reproduced using the official demo
https://github.com/apache/dubbo-samples
Just
QuickStartApplicationTests
`@SpringBootTest
class QuickStartApplicationTests {
**@DubboReference(scope = "remote")
private DemoService demoService;**
@Test
void contextLoads() {
**for (int i = 0; i < 100; i++) {
int finalI = i;
executeJob(() -> {
String result = demoService.sayHello("world" + finalI);
System.out.println("Receive result ======> " + result);
});
}**
}
**public static void executeJob(Runnable handle) {
executeJob(handle, null);
}
public static void executeJob(Runnable handle, Runnable
exceptionHandler) {
handle.run(); // excute job
}**
}
`
DemoServiceImpl
`@DubboService
public class DemoServiceImpl implements DemoService {
@Override
public String sayHello(String name) {
**try {
Thread.sleep(1000);
} catch (InterruptedException e) {
throw new RuntimeException(e);
}**
return "Hello " + name;
}
}`
