我可以在控制器内的调试中停止，但该方法返回字符串“greeting”而不是模板。
src/main/java/controllers/GreetingController.java
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/")
public class GreetingController {
@GetMapping("greeting")
public String greeting(@RequestParam(name = "name", required = false, defaultValue = "World") String name,
Model model) {
model.addAttribute("name", name);
return "greeting";
}
}
src/main/resources/templates/greeting.html

你可以尝试使用 @Controller 而不是 @RestController 吗？
