SpringBoot设置首页(默认页)跳转

方案1：controller里添加一个"/"的映射路径

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

方案二：设置默认的View跳转页面

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