Java中Spring Boot web应用程序的问题？,java,spring,maven,Java,Spring,Maven,我对弹簧靴很陌生。我在看文档，试着玩东西。我喜欢不必像SpringMVC应用程序那样对配置进行任何处理的整个想法，但后来我试图通过将数据放入模型对象来连接我的控制器和视图。但由于某些原因，我没有得到我在视图中寻找的东西。有人能指出我的错误吗。 这是我的控制器类- package com.example.LoginAndRegistration; import java.util.Map; import org.springframework.ui.Model; import org.spri

我对弹簧靴很陌生。我在看文档，试着玩东西。我喜欢不必像SpringMVC应用程序那样对配置进行任何处理的整个想法，但后来我试图通过将数据放入模型对象来连接我的控制器和视图。但由于某些原因，我没有得到我在视图中寻找的东西。有人能指出我的错误吗。 这是我的控制器类-

package com.example.LoginAndRegistration;

import java.util.Map;

import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class LoginController {

    @RequestMapping("/Login")
    public String welcome(Model model) {
        model.addAttribute("login", "Hello World");
        return "loginview";
    }

}
我已经使用ThymleAF将模型对象渲染到视图中。我通过Maven添加了thymeleaf依赖项，然后在Springboot应用程序的templates文件夹中添加了以下html文件。但是我仍然没有从我的控制器那里得到我正在传递的信息。而是将loginview打印为字符串，而不是在我的模板文件夹中查找loginview并打印消息HelloWorld

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="ISO-8859-1"></meta>
<title>Insert title here</title>
</head>
<body>
Message: <span th:text="${login}"></span>
</body>
</html>
