Description:
Parameter 0 of constructor in com.example.security.service.UserServiceImpl required a bean of type 'com.example.security.dao.UserDao' that could not be found.

Disconnected from the target VM, address: '127.0.0.1:52540', transport: 'socket'
Process finished with exit code 1
解决方法:
1、需要在启动类加上以下注解
@EnableJpaRepositories(basePackages = {“com.example.security”})
@EntityScan(basePackages = {“com.example.security”})
/**
* {@link EnableJpaRepositories} 扫描 @Repository 注解
* {@link EntityScan} 扫描 @Entity 注解
* {@link ComponentScan}扫描 @Controller、@Service 注解
* @author
*/
@SpringBootApplication
@EnableJpaRepositories(basePackages = {"com.example.security"})
@EntityScan(basePackages = {"com.example.security"})
@ComponentScan({"com.example.security"})
public class BootStartApplication {
public static void main(String[] args) {
SpringApplication.run(BootStartApplication .class, args);
}
}
2、将启动类移至项目根目录
