无法在wildfly-swarm上启动jax-rs服务

Question

我有一个JAX-RS服务,可以在本地使用wildfly-swarm 1.0.0.Beta8,但是当我在远程机器上启动它时,我得到以下异常:

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: Failed to start service jboss.undertow.listener.default: org.jboss.msc.service.StartException in service jboss.undertow.listener.default: Could not start http listener

    ... 5 more

此外,当我将应用程序部署到完整的野生动物10时,它的工作正常.

我用谷歌搜索"协议族不可用"例外可能与只有IPv6地址的机器有关,而java默认为IPv4,但这台机器确实有一个IPv4地址.

我不知道我可能做错了什么.

有什么建议？

Answer 1

您可以尝试修改wildfly-swarm-plugin以进行如下设置:

  <plugin>
    <groupId>org.wildfly.swarm</groupId>
    <artifactId>wildfly-swarm-plugin</artifactId>
    <configuration>
      <mainClass>org.wildfly.swarm.examples.netflix.ribbon.frontend.Main</mainClass>
      <properties>
        <java.net.preferIPv4Stack>true</java.net.preferIPv4Stack>
      </properties>
    </configuration>
    <executions>
      <execution>
        <goals>
          <goal>package</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

它可能需要将java.net.preferIPv4Stack设置为true.
