我正在使用Netbeans和Glassfish。我最近创建了一个新的Maven Web应用程序。我添加了一个新的WebServlet,它运行正常。
@WebServlet(name = "DbTest", urlPatterns = {"/DbTest"})
public class DbTest extends HttpServlet {
/**
* Processes requests for both HTTP <code>GET</code> and <code>POST</code>
* methods.
*
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException {
response.setContentType("text/html;charset=UTF-8");
Session session = StartupBean.sessionFactory.openSession();
session.beginTransaction();
.....
现在我想添加一些RESTful Web服务。所以我又增加了一个课程。
@Path("/yeahbuddy/")
public class YeahbuddyResource {
@GET
public String getAllYeahbuddies() {
return "WE GOT GOT";
}
}
然后我清理,构建,运行服务器,......没有。我尝试点击以下网址:
http://localhost:8080/myapp/webresources/yeahbuddy/
http://localhost:8080/myapp/yeahbuddy/
http://localhost:8080/myapp/resources/yeahbuddy/
我得到的只有404.然后我想,我一定错过了一些东西,并使用向导从模式中添加RESTful Web服务。同样的问题。
我觉得我缺少一些配置选项,比如注释不够,或者REST注释正在与WebServlet注释作斗争。
思想?
编辑:答案是添加以下web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>test</display-name>
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<!-- Register resources and providers under com.vogella.jersey.first package. -->
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.myapp.resources</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/api/*</url-pattern>
</servlet-mapping>
</web-app>
它开始为以下网址工作:
http://localhost:8080/myapp/api/yeahbuddy/
答案 0 :(得分:1)
由于您打算在Glassfish上使用Restful,我假设您将使用Jersey实现的Jax-RS,因此您必须在web.xml中定义它,如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>com.vogella.jersey.first</display-name>
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>paramValue</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/yeahbuddy/*</url-pattern>
</servlet-mapping>
</web-app>
因此,例如,带有/ yeahbuddy / ...的网址发出的每个请求都会映射到您的Rest类。
