Question

我是spring框架的新手，以后也想使用百里香。但是，现在，我只想创建一个基本页面，在其中可以直接从一个选项卡跳转到另一个选项卡。当我启动程序时，我可以停留在“主页”页面，但是如果我想从导航中打开其他选项卡，则会收到错误消息。据我了解映射问题，但无法意识到问题出在哪里。

错误：

Whitelabel错误页面此应用程序没有针对/ error的显式映射，因此您将其视为后备。

来自控制器的代码：

package com.project.project.ui.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class WelcomeController {

    @RequestMapping("/home")
    public String welcome() {
        return "index";
    }

    @RequestMapping(value = "/aphoto", method = RequestMethod.GET)
    public String add() {
        return "prideti";
    }

}

index.html中的代码

Answer 1

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.

错误意味着，根据控制器的映射，您没有html文件，或者没有将它们放在项目中的正确位置。

如果您使用的是SpringBoot，则需要在路径index.html上创建prideti.html和ApplicationRoot/src/main/resources/templates/。

遇到我无法访问其他.html文件的问题
