springboot项目创建常见问题(建议收藏！！) https://blog.csdn.net/libusi001/article/details/97267365

一、问题描述

  1. Description:
  3. Parameter 0 of constructor in com.god.demo.app.service.impl.SysUserServiceImpl required a bean of type 'com.god.demo.app.dao.mapper.SysUserMapper' that could not be found.
  6. Action:
  8. Consider defining a bean of type 'com.god.demo.app.dao.mapper.SysUserMapper' in your configuration.
  10. Disconnected from the target VM, address: '127.0.0.1:63159', transport: 'socket'

二、创建文件MyBatisConfig

  1. @MapperScan("com.xx.dao.mapper")
  2. @Configuration
  3. public class MyBatisConfig {
  5.     @Bean
  6.     public ConfigurationCustomizer configurationCustomizer() {
  7.         return configuration -> {
  8.             //驼峰命名法
  9.             configuration.setMapUnderscoreToCamelCase(true);
  10.         };
  11.     }
  12. }

三、或者直接

  1. @MapperScan("com.xx.dao.mapper")
  2. @SpringBootApplication
  3. public class DemoApplication {
  5.     public static void main(String[] args) {
  6.         SpringApplication.run(DemoApplication.class, args);
  7.     }
  9. }
