Wildfly-swarm：无法访问 jax-rs 资源（404 未找到）

Question

我想试试 wildfly-swarm。我用 Jax-rs 部分和一个简单的 hello world 资源创建了一个项目。我运行它但我得到 404 未找到。

这是我的 pom.xml

                </execution>
            </executions>
        </plugin>
    </plugins>

这是我的 Jax-rs 资源

package org.aca.studies;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/app")
public class Resource {

  @GET
  @Path("/greet")
  @Produces("text/html")
  public String greet() {
    return System.currentTimeMillis() + "";
  }
}

如您所见，它非常简单。也许我错过了什么。我没有添加带注释的 @ApplicationPath class 因为根据文档 (https://wildfly-swarm.gitbooks.io/wildfly-swarm-users-guide/content/common/jax-rs.html) this fraction adds one by default. Another thing I picked up from the examples on GitHub (https://github.com/wildfly-swarm/wildfly-swarm-examples/tree/master/jaxrs/jaxrs) 是这样的：

Since WildFly Swarm apps tend to support one deployment per executable, it automatically adds a jboss-web.xml to the deployment if it doesn't already exist. This is used to bind the deployment to the root of the web-server, instead of using the .war's own name as the application context.

所以这就是我尝试从 http://localhost:8080/app/greet

访问我的资源的原因

Answer 1

根据你的 pom，我认为问题是你没有 <packaging>war</packaging>，这意味着创建了一个 JAR。

如果你把 Maven 打包改成 WAR 那么应该没问题
