My mapperImpl by mapstruct is not generating getters and setters

i would like to know why my mapperImpl generated by mapstruct isnt being generated with getters and setters.

I think that because of this, when i go make a GET request on postman it returns all null what shouldnt be returning null.

Im using maven, java 8 and spring-boot

If someone know how to solve, please help. Thanks ;)

Solution 1:

If you want to use mapstruct together with lombok you have to include lombok-mapstruct-binding in your pom.xml

have a look at "Can I use MapStruct together with Project Lombok?" under https://mapstruct.org/faq/

like this:

<annotationProcessorPaths>
    <path>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>${lombok.version}</version>
    </path> 
    <path>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok-mapstruct-binding</artifactId>
        <version>0.2.0</version>
    </path>
    <path>
        <groupId>org.mapstruct</groupId>
        <artifactId>mapstruct-processor</artifactId>
        <version>1.4.1.Final</version>
    </path>
</annotationProcessorPaths>

My mapperImpl by mapstruct is not generating getters and setters
