Question

我正在尝试获取客户端的IP地址和端口，但是当我部署代码时，它会给我以下输出：

module.exports = "something";

这是我的REST服务器中的代码

如果我删除@Context HttpServletRequest请求它会完美运行。

Answer 1

您无需在参数..

中传递@context

这是我的界面：

@POST
@Path("/lookup")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
List<Client> searchClient(Criterias cr);

这是我的班级：

@Stateless
public class XServiceImpl implements XService {

    @Context
    private HttpServletRequest request;

    @Override
    @Public
    public List<Client> searchClient(Criterias cr) {

        try {
            List<Client> baux = null;
            String lang = RequestContext.getLocale(request).getLanguage();
            cr.setLang(lang);

        } catch (SQLException e) {
            LOGGER.log(Level.SEVERE, e.getLocalizedMessage());
            throw new ServiceException();
        } finally {
            reqInfo.logExecutionTime();
        }

    }

Answer 2

好的我明白了：

@Context
private HttpContext request;

@POST
@Consumes(MediaType.TEXT_PLAIN)
public Response loginUser(String username) {

    String netIP = request.getRequest().getRequestUri().getHost().toString();
    int netPort = request.getRequest().getRequestUri().getPort();
    ...
}

注入对象的类型错误，我使用了com.sun.jersey.api.core.HttpContext;代替。

注入调用方IP地址和端口在Java Jersey RESTful Web服务中不起作用
