[英]ServletContextListener isn't invoked when using com.sun.net.httpserver.HttpServer
I use com.sun.net.httpserver.HttpServer
in integration tests. 我在集成测试中使用com.sun.net.httpserver.HttpServer
。 It does its job but I've noticed that ServletContextListener's
methods aren't invoked during tests. 它完成了它的工作,但我注意到在测试期间未调用ServletContextListener's
方法。 When I deploy the app to the real Tomcat server I can see its methods being called. 当我将应用程序部署到真正的Tomcat服务器时,可以看到其方法被调用。
Below is the listener class: 下面是侦听器类:
package abc;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;
@WebListener
public class StartupListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent event) {
System.out.println("########################################");
}
@Override
public void contextDestroyed(ServletContextEvent event) {
System.out.println("########################################");
}
}
Here is how I start the HttpServer
in the test: 这是我在测试中启动HttpServer
的方法:
@BeforeClass
public static void startServer() {
URI uri = UriBuilder.fromUri("http://localhost/").port(8080).build();
// Create an HTTP server listening at port 8080
try {
server = HttpServer.create(new InetSocketAddress(uri.getPort()), 0);
} catch (IOException e) {
e.printStackTrace();
fail();
}
// Create a handler wrapping the JAX-RS application
HttpHandler handler = RuntimeDelegate.getInstance().createEndpoint(new ApplicationConfig(), HttpHandler.class);
// Map JAX-RS handler to the server root
server.createContext(uri.getPath(), handler);
// Start the server
server.start();
}
Maven dependency: Maven的依赖:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
I removed @WebListener
and inserted 我删除了@WebListener
并插入
metadata-complete="false"
and 和
<listener>
<listener-class>abc.StartupListener</listener-class>
</listener>
in web.xml
but it didn't help 在web.xml
但没有帮助
What is the problem? 问题是什么? Is there anything that needs to be setup? 有什么需要设置的吗?
What is the problem? 问题是什么?
HttpServer is not a servlet container and does not know about servlet api. HttpServer不是servlet容器,也不知道servlet api。
Is there anything that needs to be setup? 有什么需要设置的吗?
You need to setup a servlet container like jetty, which is frequently used for unit testing java based web applications. 您需要设置一个像jetty这样的servlet容器 ,该容器经常用于基于Java的Web应用程序的单元测试。
