本文介绍如何在Spring MVC中实现零XML配置，通过Java代码配置DispatcherServlet和WebApplicationContext，避免了传统的XML配置文件。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

使用如下代码时：

public class MyWebApplicationInitializer implements WebApplicationInitializer {

@Override public void onStartup(ServletContext container) {

ServletRegistration.Dynamic registration = container.addServlet("example", new DispatcherServlet());

registration.setLoadOnStartup(1);

registration.addMapping("/example/*");

}

会发生如下错误

Spring MVC looks for a file named example-servlet.xml in the WEB-INF

实现基于java的零xml配置，需要在DispatcherServlet 里面设置

WebApplicationContext

具体方法如下

AnnotationConfigWebApplicationContext servletAppContext = new AnnotationConfigWebApplicationContext();
Class<?>[] configClasses = new Class[]{WebConfig.class};
if (!ObjectUtils.isEmpty(configClasses)) {
    servletAppContext.register(configClasses);
}
new DispatcherServlet(servletAppContext);
