java - 如何在Spring Boot应用程序中配置DispatcherServlet？

在传统的Spring Web应用程序中，可以重写AbstractDispatcherServletInitializer.createDispatcherServlet，调用super.createDispatcherServlet，然后在返回的实例上设置以下init参数吗？

setThreadContextInheritable
setThrowExceptionIfNoHandlerFound

如何在Spring Boot应用程序中实现此目的？

最佳答案

您可以定义自己的配置并实现它，如下所示:

@Configuration
public class ServletConfig {

@Bean
public DispatcherServlet dispatcherServlet() {
    DispatcherServlet dispatcherServlet = new DispatcherServlet();
    dispatcherServlet.setThreadContextInheritable(true);
    dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
    return dispatcherServlet;
}

@Bean
public ServletRegistrationBean dispatcherServletRegistration() {

    ServletRegistrationBean registration = new ServletRegistrationBean(dispatcherServlet());
    registration.setLoadOnStartup(0);
    registration.setName(DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_REGISTRATION_BEAN_NAME);

    return registration;
}

}
