问题描述
我已经开始使用 Spring MVC 和 Spring Boot 创建一个 hello World Web 应用程序的教程.我无法让应用程序启动 hello.jsp.
I have started a tutorial to create a hello World web app using Spring MVC and Spring Boot. I cannot make the app to launch the hello.jsp.
这是我的项目配置:
应用类:
@Configuration
@ComponentScan
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
HelloController 类:
HelloController class:
@RestController
public class HelloController {
@RequestMapping(value="/greeting",method= RequestMethod.GET)
public String sayHello (Model model){
model.addAttribute("greeting","Hello World!");
return "HELLO!";
}
}

hello.jps file:

<meta http-equiv="Content-Type" content="text/html; charset=US-ASCII">
<title>Insert title here</title>
</head>
<body>
<h1>${greeting}</h1>
</body>
</html>网页结果:
正在获取 sayHello 方法的返回值，而不是 model.addAttribute("greeting","Hello World!").即使我删除了 hello.jsp 文件，我仍然得到相同的结果.
Is picking up the return value of sayHello method instead of the model.addAttribute("greeting","Hello World!"). Even if I delete the hello.jsp file I still get the same result.
任何想法为什么不读取此文件?错了吗?
Any ideas why is not reading this file? is it incorrect?
非常感谢！！！
推荐答案
您正在使用 RestController 其响应返回类型即Hello！"...因此您可以使用 @Controller 而不是 @RestController.
You are using RestController which response return type i.e "Hello!"... so you can use @Controller rather than @RestController.
