Spring cloud function [Azure] TimerTrigger

问题

Anybody has Spring cloud Function [Azure] TimerTrigger sample implementation ?Please do share

回答1:

I was able to get this running by doing the following (this is based off the HttpTrigger code):

Create the handler that has the TimerTrigger:

@Component
public class TimerHandler extends AzureSpringBootRequestHandler<User, Greeting> {

    @FunctionName("timedTrigger")
    public void timedTrigger(
            @TimerTrigger(name = "trigger", schedule = "0 */30 * * * *") String timerInfo,
            ExecutionContext context) {

        // We need to invoke the handleRequest so our spring function (defined as a bean) will be invoked.
        Greeting g = handleRequest(new User("Trigger"), context);
    }
}

Add your bean (with the same name as the function above).

@SpringBootApplication(
        scanBasePackages = "your.package.structure"
)
public class SpringApp {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(TimedHandler.class);
    }

    @Bean
    public Function<User, Greeting> timedTrigger() {        
        return user -> new Greeting("Welcome, " + user.getName());
    }

}

After you get the base working you can modify the AzureSpringBootRequestHander type and the Function types.

This is the sample of httptrigger:

https://github.com/spring-cloud/spring-cloud-function/tree/master/spring-cloud-function-adapters/spring-cloud-function-adapter-azure

you can replace the httptrigger with the timetrigger:

@FunctionName("TimerTriggerJava1")
    public void run(
        @TimerTrigger(name = "timerInfo", schedule = "0 */5 * * * *") String timerInfo,
        final ExecutionContext context
    ) {
        context.getLogger().info("Java Timer trigger function executed at: " + LocalDateTime.now());
    }

This is you need to import:

import java.time.*;
import com.microsoft.azure.functions.annotation.*;
import com.microsoft.azure.functions.*;
