注入呼叫者ip地址和端口在Java Jersey RESTful Web服務中不起作用

Question

我正在嘗試獲取客戶端的IP地址和端口，但是在部署代碼時，它會提供以下輸出：

May 10, 2016 2:50:56 PM com.sun.jersey.spi.inject.Errors processErrorMessages
SEVERE: The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Missing dependency for method public javax.ws.rs.core.Response resources.Login.loginUser(java.lang.String,javax.servlet.http.HttpServletRequest) at parameter at index 1
SEVERE: Method, public javax.ws.rs.core.Response resources.Login.loginUser(java.lang.String,javax.servlet.http.HttpServletRequest), annotated with POST of resource, class resources.Login, is not recognized as valid resource method.

這是我的REST服務器中的代碼

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.*;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

...

@POST
@Path("/post")
@Consumes(MediaType.TEXT_PLAIN)
public Response loginUser(String username, @Context HttpServletRequest request) {
    Loog.i(this, "Login di " + username);
    String netIP = request.getRemoteAddr();
    int netPort = request.getRemotePort();
    ...
}

如果我刪除@Context HttpServletRequest請求，它會完美運行。

Answer 1

您不需要在參數中傳遞@context。

這是我的界面：

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

這是我的課：

@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，我知道了：

@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();
    ...
}

注入對象的類型錯誤，我使用com.sun.jersey.api.core.HttpContext; 代替。
