Spring Boot多个servlet错误

Question

我的 Spring Boot 应用程序中有两个通过 uri 映射的 servlet， 一个映射到 /local/* 到 DispatcherServlet，另一个 /* 映射到 VaadinServlet 但是当我尝试通过 /local/blabla 访问某些内容时，也会调用 VaadinServlet。

在我的 JBoss 应用程序中不会发生这种情况，是否需要在 Spring Boot 中设置任何配置？

我注意到另一个问题，为什么要映射到“/”？我可以禁用它吗，因为我不需要使用这个 uri。

例如： https://localhost:9043/test/local/userRemote

@Bean
public ServletRegistrationBean vaadinServletRegistrationBean() {
    final ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new SpringVaadinServlet(),
            "/*");
    servletRegistrationBean.setOrder(10);
    return servletRegistrationBean;
}

@Bean
public ServletRegistrationBean servletRegistrationBean(final DispatcherServlet dispatcherServlet) {
    final ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(dispatcherServlet);
    servletRegistrationBean.addUrlMappings("/local/*");
    servletRegistrationBean.setOrder(5);

    return servletRegistrationBean;
}

Answer 1

我相信您需要通过创建一个与 dispatcherServlet 同名的 bean 来覆盖默认的 dispatcherServlet。从leveluplunch website 的教程中，我发现了以下内容：

@Bean
public DispatcherServlet dispatcherServlet() {
    return new DispatcherServlet();
}

/**
 * Register dispatcherServlet programmatically 
 * 
 * @return ServletRegistrationBean
 */
@Bean
public ServletRegistrationBean dispatcherServletRegistration() {

    ServletRegistrationBean registration = new ServletRegistrationBean(
        dispatcherServlet(), "/levelup/*");
    registration.setName(DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_REGISTRATION_BEAN_NAME);

    return registration;
}

Answer 2

我发现我可以通过属性文件向 DispatcherServlet 提供详细信息：

server.servlet-path=/local/*

如果想禁用DispatcherServlet，有什么办法吗？
