我正在努力在我的应用程序中实现一个 3rd 方库。我正在传递一个[WebappContext][1]到AtmosphereModule()下面。一旦进入那里，它最终会到达下面的方法并引发NoSuchMethodError异常。我有点难过。我正在使用

private void installAtmosphere(ServletContext context, Options options) {
    AtmosphereServlet servlet = null;
    try {
        servlet = context.createServlet(AtmosphereServlet.class);  //ERROR
    } catch (ServletException e) {
        throw new IllegalStateException(e);
    }

我的课：

import com.production.ApplicationContextProvider;
import com.production.workflow.process.approval.ApprovalSocketHandler;
import com.github.flowersinthesand.portal.App;
import com.github.flowersinthesand.portal.Bean;
import com.github.flowersinthesand.portal.Options;
import com.github.flowersinthesand.portal.atmosphere.AtmosphereModule;
import com.github.flowersinthesand.portal.spring.SpringModule;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;

/**
 * Created with IntelliJ IDEA.
 */
@WebListener
public class SocketInitializer implements ServletContextListener {

    public static App app;

    @Override
    public void contextInitialized(ServletContextEvent servletContextEvent) {
        AutowireCapableBeanFactory beanFactory = ApplicationContextProvider.getApplicationContext().getAutowireCapableBeanFactory();
        app =  new App(new Options().url("/socket/workstation/approval").packageOf(this), new AtmosphereModule(servletContextEvent.getServletContext()), new SpringModule(beanFactory));
        app.bean(ApprovalSocketHandler.class).init();
    }

    @Override
    public void contextDestroyed(ServletContextEvent servletContextEvent) {

    }
}

您是否尝试将 servlet 版本设置为 3+？

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
 </dependency>
