DI and IOC happening through web.xml where you created the dispatcherservlet. DI和IOC通过在您创建调度程序servlet的web.xml中发生。 From Spring MVC docs : The DispatcherServlet, provides a shared algorithm for request processing while actual work is performed by configurable, delegate components The DispatcherServlet, as any Servlet, needs to be declared and mapped according to the Servlet specification using Java configuration or in web.xml. 来自Spring MVC文档：DispatcherServlet提供了一种用于请求处理的共享算法，而实际工作由可配置的委托组件执行。DispatcherServlet和任何Servlet一样，都需要根据Servlet规范使用Java配置或在Web中声明和映射。 XML。 In turn the DispatcherServlet uses Spring configuration to discover the delegate components it needs for request mapping, view resolution, exception handling, and more. 反过来，DispatcherServlet使用Spring配置发现请求映射，视图解析，异常处理等所需的委托组件。

internally it will register Spring mvc app and it will create an object and inject dependencies . 在内部它将注册Spring mvc应用程序，并且将创建一个对象并注入依赖。
