Question

我是一个春季启动项目（带有嵌入式jetty9的可执行jar）。

我应该注册2个不同的DispatcherServlet。我这样做了：

@Bean
public ServletRegistrationBean dispatcherServlet() {
    DispatcherServlet servlet = new DispatcherServlet();
    ServletRegistrationBean sr = new ServletRegistrationBean(servlet, "/graniteamf/*");
    return sr;
}

@Bean
    @Order(2)
    public ServletRegistrationBean customDispatcherServlet() {
        DispatcherServlet servlet = new DispatcherServlet();
        ServletRegistrationBean sr = new ServletRegistrationBean(servlet, "/client/*");
        return sr;
    }

不幸的是，当我尝试启动应用程序时，我遇到了这个例外：

我有两个问题：

对于dispatcherServlet的xml文件是必需的吗？
Spring希望在哪个文件夹中找到这个文件？我试图把它放到资源/ WEB-INF中，但它没有用。

这是我在Spring Boot中的主要方法：

@SpringBootApplication

public class Application { private static Logger log = Logger.getLogger（Application.class）;

private static ApplicationContext context;

public static void main(String[] args) {        
    SpringApplication app = new SpringApplication(Application.class);
    app.setShowBanner(false);
    context = app.run(args);
    app.setShowBanner(false);
}

您不需要XML，但您需要在servlet上设置ApplicationContext。如果它是@Bean（就像Spring Boot中的DispatcherServletAutoConfiguration那样），Spring会为你做的，或者我猜你可以手动完成。

Spring启动DispatcherServlet
