可以在Olingo中使用@WebServlet注釋嗎？我想避免在我們的條目中創建條目：web.xml<servlet> <servlet-name>CarServiceServlet</servlet-name> <servlet-class>org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet</servlet-class> <init-param> <param-name>javax.ws.rs.Application</param-name> <param-value>org.apache.olingo.odata2.core.rest.app.ODataApplication</param-value> </init-param> <init-param> <param-name>org.apache.olingo.odata2.service.factory</param-name> <param-value>com.sample.CarServiceFactory</param-value> </init-param> <load-on-startup>1</load-on-startup></servlet><servlet-mapping> <servlet-name>CarServiceServlet</servlet-name> <url-pattern>/CarService.svc/*</url-pattern></servlet-mapping>該代碼是從olingo-sample存儲庫中獲取的。也許有一種方法@WebInitParams可以創建init參數，但是我必須注釋一下- class X extends ODataServiceFactory？它慷慨地工作嗎？編輯：我正在使用Olingo V2和Tomcat 8。

當然，您可以使用注釋來做到這一點。您將必須創建一個類，該類從注解中擴展CXFNonSpringJaxrsServletinit參數并在其中傳遞@WebServlet。
以下是復制您的代碼的代碼web.xml。
package com.sample;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
import org.apache.cxf.jaxrs.servlet.CXFNonSpringJaxrsServlet;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* @author Shiva Saxena
*
*/
@WebServlet(name = "CarServiceServlet", value = "/CarService.svc/*", initParams = {
@WebInitParam(name = "javax.ws.rs.Application", value = "org.apache.olingo.odata2.core.rest.app.ODataApplication"),
@WebInitParam(name = "org.apache.olingo.odata2.service.factory", value = "com.sample.CarServiceFactory") })
public class MyServlet extends CXFNonSpringJaxrsServlet {
Logger logger = LoggerFactory.getLogger(MyServlet.class);
private static final long serialVersionUID = -5663461069269732798L;
@Override
public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException {
// It is not necessory to override this function.Its here just for logging and better understanding
logger.info("Call intercepted by:" + this.getClass().getName());
super.service(req, res);
}
}
