在glassfish上部署REST服务4

Question

我无法启动我的REST服务.我有一个包含我的service.jar的war文件,在service.jar中我有我的webservice,代码如下

import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import se.questify.entities.exam.Question;


@Path("/services/question")
public class QuestionWebService {

    @GET
    @Path("/ping")
    @Produces({MediaType.TEXT_PLAIN})
    public String ping() {
        return "ping from localhost webservice";
    }
}

当它被部署到glassfish 4(我从eclipse运行)时,无法访问web服务http://localhost:8080/web/services/question/ping(我的上下文根是/ web).

任何人都知道为什么这不起作用？

在web.xml

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">


    <display-name>Counter Web Application</display-name>

    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>
            javax.faces.webapp.FacesServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet> 

    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.jsf</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.xhtml</welcome-file>
    </welcome-file-list>
</web-app>

Answer 1

您尚未设置到REST servlet的映射.你需要在你的web.xml文件中这样的东西:

<servlet-mapping>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
    <url-pattern>/services/*</url-pattern>
</servlet-mapping>

或者,您可以添加应用程序类并使用设置映射@ApplicationPath.

@ApplicationPath("/services")
public class QuestionApplication extends Application {
    @Override
    public Set<Class<?>> getClasses() {
        final Set<Class<?>> classes = new HashSet<>();
        // register root resource
        classes.add(QuestionWebService.class);
        return classes;
    }
}

然后设置@Path与映射URL的关系.

@Path("/question") 
public class QuestionWebService {
...
}
