Question

我正在学习Spring Framework。我在home.html中添加了resources/templates/home.html。但是当我访问http://localhost:8080时看不到它。我有以下结构：

taco-cloud \ src \ main \ java \ tacos \ TacoCloudApplication.java

package tacos;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class TacoCloudApplication {

    public static void main(String[] args) {
        SpringApplication.run(TacoCloudApplication.class, args);
    }

}

taco-cloud \ src \ main \ java \ tacos \ HomeController.java

package tacos;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
public class HomeController 
{
    @GetMapping("/")
    public String home()
    {
        return "home.html";
    }
}

taco-cloud \ src \ main \ resources \ static \ home.html

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:th="http://www.thymeleaf.org">
 <head>
 <title>Taco Cloud</title>
 </head>
 <body>
 <h1>Welcome to...</h1>
 <img th:src="@{/images/TacoCloud.png}"/>
 </body>
</html>

输出

可泛白的错误页面

本地主机：8080 / home.html 显示home.html

Answer 1

您必须将主页的位置更改为static文件夹中：

resources/static/home.html
          ^^^^^^

代替

resources/templates/home.html

并在控制器中指定扩展名：

return "home.html";
            ^^^^^

否则，您必须创建视图解析器以避免使用扩展名，并指定页面的其他位置，请查看Configure ViewResolver with Spring Boot and annotations gives No mapping found for HTTP request with URI error

Answer 2

您可以尝试一下。

account_balance - LAG(account_balance) OVER(PARTITION BY department ORDER BY timestamp ASC) delta
