spring-boot 2.5.2 带有 mapstruct\lombok 和 swagger2 (mapstruct 不起作用)

Question

我将spring-boot的项目框架从[2.1.0.RELEASE]升级到[2.5.2]和一些依赖项，但是现在swagger2和mapstruct不能一起工作。我也使用lombok。这是我的pom.xml(删除一些不相关的东西)，但现在我得到了错误:

java: package org.mapstruct does not exist

    </plugins>
</build>

如果我删除

<exclusion>
   <groupId>org.mapstruct</groupId>
   <artifactId>mapstruct</artifactId>
</exclusion>

来自 swagger2，然后我收到此错误。

java: Couldn't retrieve @Mapper annotation

那么，遇到这种情况我该怎么办，谢谢。 顺便说一句，我使用的是 Intellij IDEA 2021.1。

Answer 1

不好意思，我没注意到

<dependency>
    <groupId>org.mapstruct</groupId>
    <artifactId>mapstruct-jdk8</artifactId>
    <version>${org.mapstruct.version}</version>
</dependency>

更改为

        <dependency>
          <groupId>org.mapstruct</groupId>
          <artifactId>mapstruct</artifactId>
          <version>${org.mapstruct.version}</version>
        </dependency>

已成功。
