运行Maven后，它会说：“WildFly Swarm准备好了”，我没有收到任何错误，因此我尝试在中写入以下URL:localhost:8080/hello结果是以下消息：“未找到”我尝试使用Edge、Firefox或Chrome，但没有成功

所以这里有一些问题。首先，您缺少了

JAX-RS

Swarm部分。这意味着

pom.xml

中的依赖项需要如下所示：

  <dependencies>
    <!-- Java EE 7 dependency -->
    <dependency>
      <groupId>javax</groupId>
      <artifactId>javaee-api</artifactId>
      <version>7.0</version>
      <scope>provided</scope>
    </dependency>
    <!-- WildFly Swarm Fractions -->
    <dependency>
      <groupId>org.wildfly.swarm</groupId>
      <artifactId>jaxrs</artifactId>
    </dependency>
  </dependencies>

---

这将把您的

JAX-RS

路径设置为

/

。一种常见的模式是使用类似于

/rest

或

/svc

的东西，但目前这对您来说很好。

在这种情况下，不建议指定Jax-RS依赖关系。Swarm在自动检测方面做得相当出色。
