REST web服务的多个版本 - 执行错误

我正在尝试创建一个v2的web服务。为此，我创建了一个新的包com.package.v2，其中声明了远程接口。如果我保持v2的类名称与v1相同，那么在部署到glassfish服务器期间出现错误。REST web服务的多个版本 - 执行错误

SEVERE|glassfish3.1.2|com.sun.jersey.spi.inject.Errors|_ThreadID=61;_ThreadName=Thread-2;|The following errors and warnings have been detected with resource and/or provider classes: 
SEVERE: The class com.package.v2.TestRESTServiceBA is an interface and cannot be instantiated.|#]

如果我将v2类重命名为不同的名称，那么一切正常。您能否让我知道如何保留同名的版本？

更多细节： INFO | glassfish3.1.2 | com.sun.jersey.api.core.ScanningResourceConfig | _ThreadID = 61; _ThreadName =线程2; |根资源类发现：

接口com.package .v2.TestRESTServiceBA

接口com.package.v1.TestRESTServiceBA

添加代码：

版1个接口

package com.package.v1; 

import java.util.Map; 
import javax.ejb.Remote; 
import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import com.package.common.dto.ResponseDTO; 

@Remote 
@Path("/v1/test") 
public interface TestRESTServiceBA { 

    @GET 
    @Path("/headers") 
    @Produces("application/json") 
    ResponseDTO<Map<String, String>> getAllHeaders(); 
}

版本1实施

package com.package.v1; 

import java.util.Enumeration; 
import java.util.HashMap; 
import java.util.Map; 
import javax.ejb.Stateless; 
import javax.servlet.http.HttpServletRequest; 
import javax.ws.rs.core.Context; 
import org.apache.commons.logging.Log; 
import org.apache.commons.logging.LogFactory; 
import com.package.common.dto.ResponseDTO; 
import com.package.v1.TestRESTServiceBA; 

@Stateless 
public class TestRESTServiceBABean implements TestRESTServiceBA { 

    private static final Log LOG = LogFactory.getLog(TestRESTServiceBABean.class); 

    @Context 
    private HttpServletRequest request; 

    public TestRESTServiceBABean() { 
    } 

    @Override 
    public ResponseDTO<Map<String, String>> getAllHeaders() { 
     LOG.info("GET:v1/test/headers requested!"); 
     final ResponseDTO<Map<String, String>> response = new ResponseDTO<>(); 
     return response; 
    } 
}

2版接口包com.package.v2;

import java.util.Map; 
import javax.ejb.Remote; 
import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import com.package.common.dto.ResponseDTO; 

@Remote 
@Path("/v2/test") 
public interface TestRESTServiceBA2 { 

    @GET 
    @Path("/headers") 
    @Produces("application/json") 
    ResponseDTO<Map<String, String>> getAllHeaders(); 
}

版2实施包com.package.v2;

import java.util.HashMap; 
import java.util.Map; 
import javax.ejb.Stateless; 
import javax.servlet.http.HttpServletRequest; 
import javax.ws.rs.core.Context; 
import org.apache.commons.logging.Log; 
import org.apache.commons.logging.LogFactory; 
import com.package.common.dto.ResponseDTO; 
import com.package.common.model.DealerSpeedUser; 
import com.package.v2.TestRESTServiceBA2; 


@Stateless 
public class TestRESTServiceBABean implements TestRESTServiceBA { 

    private static final Log LOG = LogFactory.getLog(TestRESTServiceBABean2.class); 

    @Context 
    private HttpServletRequest request; 

    public TestRESTServiceBABean2() { 
    } 

    @Override 
    public ResponseDTO<Map<String, String>> getAllHeaders() { 
     LOG.info("GET:v2/test/headers requested!"); 

     final ResponseDTO<Map<String, String>> response = new ResponseDTO<>(); 
     return response; 
    } 
}

你能提供代码吗？这显然不足以帮助你 –

错误是告诉你，因为你已经把@Path@GET，@Produces等注解接口类不能创建一个接口的实例。相反，将这些注释移动到TestRESTServiceBABean类。
