How can I rewrite it for SpringBootServletInitializer?
如何为 SpringBootServletInitializer 重写它？
采纳答案by Dave Syer
If I take your question at face value (you want a SpringBootServletInitializerthat duplicates your existing app) I guess it would look something like this:
如果我从表面SpringBootServletInitializer上看你的问题（你想要一个重复你现有的应用程序），我想它看起来像这样：
@Configuration
public class Restbucks extends SpringBootServletInitializer {
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Restbucks.class, ComponentConfiguration.class);
}
@Bean
public MeteorServlet dispatcherServlet() {
return new MeteorServlet();
}
@Bean
public ServletRegistrationBean dispatcherServletRegistration() {
ServletRegistrationBean registration = new ServletRegistrationBean(dispatcherServlet());
Map<String,String> params = new HashMap<String,String>();
params.put("org.atmosphere.servlet","org.springframework.web.servlet.DispatcherServlet");
params.put("contextClass","org.springframework.web.context.support.AnnotationConfigWebApplicationContext");
params.put("contextConfigLocation","net.org.selector.animals.config.ComponentConfiguration");
registration.setInitParameters(params);
return registration;
}
}
See docs on converting an existing appfor more detail.

But, rather than using Atmosphere, you are probably better off these days using the native Websocket support in Tomcat and Spring (see the websocket sampleand guidefor examples).
但是，与使用 Atmosphere 相比，现在使用 Tomcat 和 Spring 中的原生 Websocket 支持可能会更好（请参阅websocket 示例和指南以获取示例）。
