使用resteasy-jaxrs 的简单示例不起作用

当我访问该页面时，我无法收到“hello”消息。

package jaxrs.ressources;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("greeting")
public class HelloRessource {
    @GET
    @Path("hello")
    @Produces(MediaType.TEXT_PLAIN)
    public String sayhello() {
    return "Hello from JAX-RS";
}}

和这个班级

package jaxrs.utilities;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/rest")
public class RestActivator  extends Application{

}

The url http://127.0.0.1:8383/JAXRS_Hello_GL-1.0/rest/greeting/hello总是显示“未找到”

有什么解决办法吗？

这是包含 pom.xml 文件的内容：

如果您需要其他说明，请告诉我

您可以添加初始化程序吗：

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-servlet-initializer</artifactId>
    <version>3.1.4.Final</version>
</dependency>
