mapstruct在eclipse生成不了mapper的实现类解决办法

依赖 mapstruct 的 jar包

<properties>
    <mapstruct.version>1.5.2.Final</mapstruct.version>
    <lombok.version>1.18.24</lombok.version>
</properties>

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

<!-- 编译插件，编译时执行 mapstruct 生成实现代码 -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <annotationProcessorPaths>
            <annotationProcessorPath>
                <groupId>org.mapstruct</groupId>
                <artifactId>mapstruct-processor</artifactId>
                <version>${mapstruct.version}</version>
            </annotationProcessorPath>
            <annotationProcessorPath>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>${lombok.version}</version>
            </annotationProcessorPath>
            <annotationProcessorPath>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok-mapstruct-binding</artifactId>
                <version>0.2.0</version>
            </annotationProcessorPath>
        </annotationProcessorPaths>
        <showWarnings>true</showWarnings>
        <compilerArgs>
            <arg>
                -Amapstruct.suppressGeneratorTimestamp=true
            </arg>
            <arg>
                -Amapstruct.suppressGeneratorVersionInfoComment=true
            </arg>
            <arg>
                -Amapstruct.verbose=true
            </arg>
        </compilerArgs>
    </configuration>
</plugin>

安装 m2e-apt 插件

在 pom 文件中加入如下配置

<properties>
    <java.version>1.8</java.version>
    <m2e.apt.activation>jdt_apt</m2e.apt.activation>
</properties>
