启动类代码
package com.maven.demo; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ComponentScan; import org.springframework.transaction.annotation.EnableTransactionManagement; @SpringBootApplication @EnableAutoConfiguration @ComponentScan("com.maven.demo") @MapperScan("com.maven.demo") @EnableTransactionManagement public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
发现路径都是对的，但是就是扫描不到controller层
原因是maven多模块项目忘记引入子模块的maven依赖了，启动类是一个子模块，controller的代码是另外一个子模块，低级错误。
