Spring 引导自定义 Servlet 未映射到 bean 名称

Spring boot custom Servlet doesn't map to bean name

我正在尝试注册自定义 servlet。

我在 @Configuration class:

中使用了这段代码
@Bean (name="probe")
public PingServlet probe(){
    return new PingServlet();
}

我以为这会映射到 /probe,但事实并非如此。我映射到“/”,原因是在 class ServletContextInitializerBeans 中,有这个方法:

private <T, B extends T> void addAsRegistrationBean(ListableBeanFactory beanFactory,
        Class<T> type, Class<B> beanType, RegistrationBeanAdapter<T> adapter) {
    List<Map.Entry<String, B>> beans = getOrderedBeansOfType(beanFactory, beanType,
            this.seen);
    for (Entry<String, B> bean : beans) {
        if (this.seen.add(bean.getValue())) {
            int order = getOrder(bean.getValue());
            String beanName = bean.getKey();
            // One that we haven't already seen
            RegistrationBean registration = adapter.createRegistrationBean(beanName,
                    bean.getValue(), beans.size());
            registration.setName(beanName);
            registration.setOrder(order);
            this.initializers.add(type, registration);
            if (this.log.isDebugEnabled()) {
                this.log.debug(
                        "Created " + type.getSimpleName() + " initializer for bean '"
                                + beanName + "'; order=" + order + ", resource="
                                + getResourceDescription(beanName, beanFactory));
            }
        }
    }
} 

List<Map.Entry<String, B>> beans = getOrderedBeansOfType(beanFactory, beanType, this.seen);,return 仅列出 1 个 bean(我的 servlet),尽管 beanType 是 javax Servlet,我希望 DispatcherServlet 也在那里(我也在使用 SpringMVC).

这会导致以下方法出错(在 class ServletRegistrationBeanAdapter 中):

@Override
    public RegistrationBean createRegistrationBean(String name, Servlet source,
            int totalNumberOfSourceBeans) {
        String url = (totalNumberOfSourceBeans == 1 ? "/" : "/" + name + "/");
        if (name.equals(DISPATCHER_SERVLET_NAME)) {
            url = "/"; // always map the main dispatcherServlet to "/"
        }
        ServletRegistrationBean bean = new ServletRegistrationBean(source, url);
        bean.setMultipartConfig(this.multipartConfig);
        return bean;
    }

由于 beans 列表的大小为 1,因此在 createRegistrationBean 中它将映射硬编码为“/”。

这反过来会导致他们嵌入的码头无法启动,因为有 2 个映射到“/”(DispatcherServlet 和我的 PingServlet)。

知道这里出了什么问题吗?

感谢@M。 Deinum 这有效:

@Bean
public ServletRegistrationBean pingRegistration(PingServlet pingServlet) {
    ServletRegistrationBean registration = new ServletRegistrationBean(
            pingServlet);
    registration.addUrlMappings("/probe/*");
    return registration;
}
