Migrate ManagedExecutorService to Quarkus

[towbi]

Hi there,

I'm in the process of migrating an existing TomEE (JavaEE) application to Quarkus. In this application we make frequent use of ManagedExecutorServices that get injected using the @resource annotation like this:

    @ApplicationScoped
    public class MyService {

        @Resource(name = "MyManagedExecutorService")
        private ManagedExecutorService managedExecutorService;
	...
	    managedExecutorService.submit(() -> {
	        ...
	    });
    ...

The named resource MyManagedExecutorService is defined in WEB-INF/resources.xml like this:

    <resources>
        <Resource id="MyManagedExecutorService" type="ManagedExecutorService">
            Core = 100
            Max = 100
            KeepAlive = 5 s
            Queue = 1000
        </Resource>
    ...

I researched quite a bit bit I didn't find a way to migrate these parts to Quarkus without major rewrites of the application.

Is there a straightforward way to migrate these parts to Quarkus-land?

Cheers,
towbi

You could use the Quarkus default (configurable) executor and just inject a ManagedExecutor:

@Inject ManagedExecutor executor;

This solved the issue for my case.

Just had to add implementation 'io.quarkus:quarkus-smallrye-context-propagation-spi:2.14.1.Final' to our build.gradle

What were the rewrites that you had to do for making this work? I am facing a similar issue.
