I need to use Mapstruct and this error is comming up.
*APPLICATION FAILED TO START Description: Field userMapper in com.mycomp.myappapi.service.UserService required a bean of type 'com.mycomp.myappapi.mapper.UserMapper' that could not be found. The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true) Action: Consider defining a bean of type 'com.mycomp.myappapi.mapper.UserMapper' in your configuration.*
Since there's this line in myappapiApplication.java, understand it should be able to find UserMapper.java. But for some reason it's not.
@ComponentScan(basePackages = {"com.mycomp.*"})
Also, it is not autogenerating the mapstruct implementation classes in \target folder.
package com.mycomp.myappapi;
@SpringBootApplication
@EntityScan(basePackages = {"com.mycomp.myappapi.model"})
