SpringBoot設置首頁(默認頁)跳轉功能的實現方案

最近springboot開發需要設置個默認頁面，要直接跳轉到登錄頁面。

方案1：controller里添加一個"/"的映射路徑

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

方案二：設置默認的View跳轉頁面

@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);
    //主頁
    registry.addViewController("/").setViewName("forward:/index");
  } 
}
