我找不到导致错误的原因。

这是thymeleaf告诉您那里有一些无效的XHTML。 Thymeleaf是XML，因此必须关闭所有元素。 此外，您还有一个无效的前导'

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class springbootapplicationController {

    @RequestMapping("/")
    public String welcomeController(ModelMap model) {
        model.put("welcome", "Spring boot application");
        return "index";
    }
}
