我的 mapperImpl by mapstruct 没有生成 getter 和 setter
My mapperImpl by mapstruct is not generating getters and setters
我想知道为什么我的 mapstruct 生成的 mapperImpl 没有使用 getter 和 setter 生成。
我认为正因为如此,当我向邮递员发出 GET 请求时,它 returns 全部为 null,不应该返回 null。
我正在使用 maven,java 8 和 spring-boot

如果你想将 mapstruct 与 lombok 一起使用,你必须在 pom.xml
中包含 lombok-mapstruct-binding
看看“我可以将 MapStruct 与 Project Lombok 一起使用吗?”在 https://mapstruct.org/faq/
