通过WebApplicationInitializer类实现Swagger UI

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class MyWebApplicationInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.register(MyConfig.class);

        DispatcherServlet dispatcherServlet = new DispatcherServlet(context);
        ServletRegistration.Dynamic registration = servletContext.addServlet("dispatcherServlet", dispatcherServlet);
        registration.setLoadOnStartup(1);
        registration.addMapping("/");

        // 配置Swagger UI
        configureSwagger(servletContext);
    }

    private void configureSwagger(ServletContext servletContext) {
        // 配置Swagger相关的bean和URL映射
        // ...

        // 注册Swagger UI的Servlet
        ServletRegistration.Dynamic swaggerServlet = servletContext.addServlet("swagger-ui", new SwaggerUIServlet());
        swaggerServlet.setLoadOnStartup(2);
        swaggerServlet.addMapping("/swagger-ui/*");
    }
}
