spring-boot - 在 Vaadin SpringBootApplication 中设置 Atmosphere 设置

Question

我在 Spring Boot 应用程序中使用 JDK17 和 Vaadin 22 (Flow)。我希望设置 Tomcat 使用的气氛设置。

我尝试了以下方法，但没有设置值：

@SpringBootApplication
@EnableAutoConfiguration(exclude = DataSourceAutoConfiguration.class)
@Theme(value = "sample")
@PWA(name = "sample", offlineResources = {"images/logo.png"})
@Push(PushMode.AUTOMATIC)
@WebServlet(name = "springServlet", urlPatterns = "/* ", asyncSupported = true, initParams = {
        @WebInitParam(name = "org.atmosphere.cpr.broadcaster.shareableThreadPool", value = "true"),
        @WebInitParam(name = "org.atmosphere.cpr.broadcaster.maxProcessingThreads", value = "2"),
        @WebInitParam(name = "org.atmosphere.cpr.broadcaster.maxAsyncWriteThreads", value = "2"),
        @WebInitParam(name = "org.atmosphere.cpr.maxSchedulerThread", value = "2")
})
public class Application extends SpringBootServletInitializer implements AppShellConfigurator {
    public static void main(String @NotNull [] args) {
        SpringApplication.run(Application.class,
                              args);
    }
}

尝试这样的事情

@ManagedBean
public class AtmosphereInitializer implements ServletContextInitializer {

    @Override
    public void onStartup(ServletContext servletContext) {
servletContext.setInitParameter("org.atmosphere.cpr.broadcaster.maxProcessingThreads","2");
servletContext.setInitParameter("org.atmosphere.cpr.broadcaster.shareableThreadPool","true");
...

    }
}
