推荐答案

当你使用 Java 代码(而不是 XML)来配置你的 Spring 应用程序时，@EnableWebMvc 用于启用 SpringMVC.如果您还不熟悉 Spring 对 Java 配置的支持，这是一个很好的起点.

When you're using Java code (as opposed to XML) to configure your Spring application, @EnableWebMvc is used to enable Spring MVC. If you're not already familiar with Spring's support for Java configuration, this is a good place to start.

@EnableWebMvc 等价于 XML 中的

@EnableWebMvc is equivalent to <mvc:annotation-driven /> in XML. It enables support for @Controller-annotated classes that use @RequestMapping to map incoming requests to a certain method. You can read detailed information about what it configures by default and how to customise the configuration in the reference documentation.
