我正在练习我的springboot知识，所以我试着创建一个简单的待办事项应用程序。当我在localhost：8080/tasks/list运行我的主应用程序时，即使我为我的html文件配置了正确的路由，我也会得到一个白标签错误页面。我现在使用的是JSP，我也创建了一个thymeleaf版本，但我仍然会得到同样的错误。谢谢！

package task.springboot.todo;
import org.springframework.boot.SpringApplication;

@SpringBootApplication
public class TodoappOracleApplication {
public static void main(String[] args) {
SpringApplication.run(TodoappOracleApplication.class, args);
}
}TaskController.java
package task.springboot.todo.controller;

@RequestMapping("/tasks")
public class TaskController {
@GetMapping("/list")
public String showTodoList() {
return "todo-list";
}

请将thymeleaf依赖项添加到
pom.xml并将文件扩展名从
.jsp更改为.html(todo-list.html)，并将其放在路径src/main/resources/templates下
