Question

import javax.inject.Inject;
import javax.inject.Singleton;
import javax.validation.Valid;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.container.AsyncResponse;
import javax.ws.rs.container.Suspended;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;

@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@Path("/add")
@Singleton
public class CounterController {

    private final CounterService counterService;

    // Resteasy/CDI requires @Context+@Singleton for constructor injection to work
    // https://issues.jboss.org/browse/RESTEASY-1538
    // http://stackoverflow.com/a/33658338/365237

    @Inject
    public CounterController(@Context CounterService counterService) {
        this.counterService = counterService;
    }

    @POST
    public void add(@Suspended final AsyncResponse asyncResponse, @Valid
            CounterRequest counterRequest) {
        asyncResponse.resume(counterService.count(counterRequest));
    }
}

和

import javax.ejb.Asynchronous;
import javax.ejb.Stateless;

@Stateless
@Asynchronous
public class CounterService {
    public CounterResult count(CounterRequest counterRequest) {
        return new CounterResult(
                counterRequest.getInt1() + counterRequest.getInt2());
    }
}

如果我使用wildfly版本2018.3.0，

工作正常，但如果我使用2018.4.0或2018.5.0，我会

示例回购：working，non-working。

我确实有beans.xml作为

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd" 
    bean-discovery-mode="all">
</beans>

我正在使用mvn clean wildfly-swarm:run。

关于事业的想法？这会是一个错误吗？我已经浏览了changelog并且没有看到与我相关的任何内容。默认情况下，只有破坏变化才会生成jax-rs Application类，但无论如何我都有这个类。

更新Wildfly Swarm版本会破坏依赖注入
