使用mapstruct 進行不同類的實體轉換

• 在pom文件添加
  

  
<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <org.mapstruct.version>1.3.0.Final</org.mapstruct.version>
    </properties>
<!-- 實體對象轉換-->
        <dependency>
            <groupId>org.mapstruct</groupId>
            <artifactId>mapstruct</artifactId>
            <version>${org.mapstruct.version}</version>
        </dependency>

• 添加插件，結合lombok 使用mapstruct
  
  <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.5.1</version>
      <configuration>
          <source>1.8</source> <!-- or higher, depending on your project -->
          <target>1.8</target> <!-- or higher, depending on your project -->
          <annotationProcessorPaths>
              <path>
                  <groupId>org.mapstruct</groupId>
                  <artifactId>mapstruct-processor</artifactId>
                  <version>${org.mapstruct.version}</version>
              </path>
              <path>
                  <groupId>org.projectlombok</groupId>
                  <artifactId>lombok</artifactId>
                  <version>${lombok.version}</version>
              </path>
          </annotationProcessorPaths>
      </configuration>
  </plugin>

• 使用示例：SOURCE, TARGET 是你的實體類

• @Mapper
  public interface ObjectMapper<SOURCE, TARGET> {
      ObjectMapperMAPPER = Mappers.getMapper(ObjectMapper.class);
  
  
      TARGET to(SOURCE source);
  
      SOURCE from(TARGET source);
  
  }
