Question

我是春季靴子的新手。当我在端口8080上启动spring-boot应用程序时出错。我明白了 Whitelabel错误页面。

我在 / src / main / resources / templates / 中创建了一个非常简单的html页面。

这是我的pom.xml。

            </plugin>
        </plugins>
    </build>
</project>

这是我的应用程序的控制器

public class BanqueController {

    @Autowired
    private IBanqueMetier banqueMetier;

    @RequestMapping("/operations")
    public String index()
    {
        return "comptes";
    }
}

应返回的html就是这个

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>MyBanQ</title>
</head>
<body>
    <h3>Test</h3>
</body>
</html>

主要应用如下。我已经尝试过这里提出的解决方案Springboot Whitelabel Error Page，但它并不适用于我。

@SpringBootApplication
public class MyBanQApplication implements CommandLineRunner {

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

}

Answer 1

将注释@Controller添加到您的控制器类。您的html文件名应该是“comptes”，就像您在索引函数中提到的那样。
