在类级别使用@path（“/”）的JAX-RS webservice在Tomee+1.5.1上失败

Question

这个简单的根资源类在Tomee+1.5.1上运行时失败，返回404错误“请求的资源不可用”。它在WEB-INF中打包为WAR with和空web.xml文件。

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.UriInfo;


@Path("/")
@Produces({ "text/plain", "text/html", "text/xml", "application/xml", "application/json" })
public class BrokenResource {
    private static final Log logger = LogFactory.getLog(BrokenResource.class);


    public BrokenResource()
    {
        logger.info("constructed");
    }

    @GET
    @Path("getloggedinguids")
    public Response foo(@Context UriInfo uInfo)
    {
        return Response.ok("\n\n\nrequest URI = " + uInfo.getRequestUri()).build();
    }
}

它进行部署，我在控制台输出中看到以下几行：

Mar 22, 2013 4:56:16 PM org.apache.openejb.server.rest.RESTService deployPojo
INFO: REST Service: http://localhost:8080/test//*  -> Pojo BrokenResource

我还尝试用web.xml将其打包，该web.xml声明：

<servlet>
    <servlet-name>test</servlet-name>
    <display-name>Test OpenEJBRest Servlet</display-name>

    <servlet-class>
        org.apache.openejb.server.rest.OpenEJBRestServlet
    </servlet-class>

    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>test</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

结果与空web.xml文件相同。

WARNING: No root resource matching request path /test/getloggedinguids has been found, Relative Path: /getloggedinguids.

Answer 1

请记住，如果您使用JAX-RS或TomEE+版本，TomEE不是在web.xml中添加条目，而是本机支持JAX-RS。

添加类似这样的类并删除web.xml条目：

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;

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


@ApplicationPath("/")
public class NoteTakerApplication extends Application {
    @Override
    public Set<Class<?>> getClasses() {
        return new HashSet<Class<?>>(Arrays.asList(BrokenResource.class, RestExceptionMapper.class, OtherClassesYouMayHave.class));
    }
}
