为了测试写了一个demo project，为了查看是否成功写了一个index.html用于显示。下面是代码，其中有几个注意事项。

 

1. index.html要放在resources/templates文件夹下。（这个和spring-boot-starter-thymeleaf的默认配置有关）

2. pom.xml中要添加spring-boot-starter-web和spring-boot-starter-thymeleaf的依赖。

 

HomeController.java

@Controller
public class HomeController {
    @RequestMapping(value = "/")
    public String home(){
        return "index";
    }
}

resources/templates/index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Demo2</title>
</head>
<body>
This is a demo for war package.
</body>
</html>
