进程已结束，退出代码为 1
1. 相关的依赖没给到位或者重复
如添加mybatis plus不需要在添加mybatis的任何依赖
<!--mybatis plus和springboot整合--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.4.1</version> </dependency>
2. 相关的注释没给到位
重复检查controller层的@Restcontroller service层的@service 和dao层的@mapper,发现没有任何错误，不是这个问题
3. yml配置文件出错
先检查yml配置文件的内容，datasource没问题，mybatis的配置也没问题，排除内容出错，网上查到可能是配置文件路径错误，yml没有读取到，重复更改yml的路径，甚至使用propreties文件，也没能解决问题，于是排除配置文件的问题
我这边报错是因为依赖mybatis重复了，把多余的mybatis删除重新加载，启动类上的@MapperScan("com.dem.mapper")没有扫描到我具体的mapper包路径，这些地方一定要注意看！！！！！我改了之后就成功了。
