对于初学者springboot报错，一般有以下原因。

1,你的application启动类的位置不对，已经application启动类放在目录的最外层。如图我的MainApplication就在com.it包下，即最外层，所以它可以包含你所有的文件。

2要是用正确的注解，如下如果我想要在页面显示hello,spring boot2!,我的所在类所加注解为@RestController,我的映射方法注释为@RequestMapping

确定要放弃本次机会？

首先我这个不是靠移动Application启动类的位置解决的，因为我一移动就报错，我不敢了。

1、报错信息上面这句话大概的意思“这个应用没有明确的映射/错误，所以你才会看到这样一个返回结果”。 2、解决方案 2.1 Application启动类的位置不对要将Application启动类放在最外侧，这样才会自动加载启动类所在包下及其子包下的所有组件。在这总结确认了目前的三种错误案例。 SpringBoot项目的Bean装配是根据Application类所在的包位置从上往下扫描！“Application类”是指SpringBoot项目入口类，这个类的位置很关键：如果Application类
