我正在尝试像在spring网站上一样构建一个spring项目，但是现在我有一个异常，该异常已经在工厂定义了。
我从github下载了spring源代码，现在它已经在我的本地环境中成功编译了，我添加了一个名为spring-demon的模块。它具有三个Java文件和一个gradle配置文件。
这是三个Java文件
public class MyWebApplicationInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletCxt) {
// Load Spring web application configuration
AnnotationConfigWebApplicationContext ac = new AnnotationConfigWebApplicationContext();
ac.register(AppConfig.class);
ac.refresh();
// Create and register the DispatcherServlet
DispatcherServlet servlet = new DispatcherServlet(ac);
ServletRegistration.Dynamic registration = servletCxt.addServlet("app", servlet);
registration.setLoadOnStartup(1);
registration.addMapping("/app/*");
}
}
@Controller
public class UsrController {
@RequestMapping("/getUser.do")
public Object getUser(){
System.out.println("getUser");
return null;
}
}
@Configuration
@ComponentScan("com")
public class AppConfig {
}
这是gradle的配置文件
buildscript {

jcenter()

}
tomcat {
