  • mapstruct 入门指南

    1、mapstruct和其他映射工具的对比请参考以下地址

     https://www.cnblogs.com/javaguide/p/11861749.html

    2、pom.xml文件中添加依赖,在使用lombok的时候mapstruct插件会不生效,引入mapstruct-jdk8来解决问题

    <dependency>
        <groupId>org.mapstruct</groupId>
        <artifactId>mapstruct-processor</artifactId>
        <version>1.3.0.Final</version>
    </dependency>
    <!-- 解决springboot 项目使用 lombok 插件后,添加 mapstruct  插件,maven 编译时 mapstruct 插件不起作用 -->
    <dependency>
        <groupId>org.mapstruct</groupId>
        <artifactId>mapstruct-jdk8</artifactId>
        <version>1.3.0.Final</version>
    </dependency>
    

    3、添加插件

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.5.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.mapstruct</groupId>
                        <artifactId>mapstruct-processor</artifactId>
                        <version>1.3.0.Final</version>
                    </path>
                </annotationProcessorPaths>
            </configuration>
        </plugin>
    </plugins>
    

    4、idea安装插件

     

     5、代码编写

    1)举例car实体

    public class Car {
    
        private String make;
        private int numberOfSeats;
        private CarType type;
    }

    2)举例cardto

    public class CarDto {
    
        private String make;
        private int seatCount;
        private String type;
    }
    

    3)举例mapper

    @Mapper
    public interface CarMapping {
    
        CarMapping INSTANCE = Mappers.getMapper( CarMapping .class );
    
        @Mapping(source = "numberOfSeats", target = "seatCount")
        CarDto carToCarDto(Car car);
    }
    

    4)使用

    CarDto carDto=CarMapping.INSTANCE.carToCarDto(car);
