SpringBoot Lombok Mapstruct不能一起工作

Question

我正在尝试使用龙目岛和MapStruct配置SpringBoot（v2.6.2），已经配置了maven编译器插件和龙目岛地图结构绑定（注释处理器路径），但龙目岛类尚未创建：

pom.xml

尝试使用DI时总是出现未初始化变量错误：

变量xxxx可能尚未初始化

Answer 1

只是仔细检查了所有内容，我缺少一些intelliJ配置。

Answer 2

是的，你也可以在这里看看接受的答案。如何指导Mapstruct使用lombok builder？这也是mapstruct的官方留档https://mapstruct.org/documentation/stable/reference/html/#_set_up

<build>
<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.8.1</version>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
            <annotationProcessorPaths>
                <path>
                    <groupId>org.mapstruct</groupId>
                    <artifactId>mapstruct-processor</artifactId>
                    <version>${org.mapstruct.version}</version>
                </path>
                <path>
                    <groupId>org.projectlombok</groupId>

                    <version>${org.projectlombok.version}</version>
                </path>

                <!-- additional annotation processor required as of Lombok 1.18.16 -->

                </path>
