SpringBoot设置首页(默认页)跳转功能的实现方案

@RequestMapping("/")
public String index(Model model, HttpServletResponse response) {
  model.addAttribute("name", "simonsfan");
  return "/index";
}

@Configuration
public class DefaultView extends WebMvcConfigurerAdapter {
  @Override
  public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("index");
    registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
    super.addViewControllers(registry);
  }
}

@Configuration
public class DefaultView extends WebMvcConfigurerAdapter{
  @Override
  public void addViewControllers(ViewControllerRegistry registry) {
    super.addViewControllers(registry);
    //主页
    registry.addViewController("/").setViewName("forward:/index");
  } 
}
