1.pom引入

<dependency>

            <groupId>org.modelmapper</groupId>

            <artifactId>modelmapper</artifactId>

            <version>2.3.8</version>

        </dependency>

2.将DAO对象转为DTO对象

User user = new User();

user.setId(1L);

user.setNickname("张三");

user.setEmail("101@qq.com");

user.setHonor("测试荣誉");

ModelMapper modelMapper = new ModelMapper();

UserDTO userDTO = modelMapper.map(user, UserDTO.class);

System.out.println(userDTO);

3.工具类

public class ModuleHelper {

    private static final ModelMapper modelMapper;

    static {

        modelMapper = new ModelMapper();

//        modelMapper.createTypeMap(String.class, Date.class);

//        modelMapper.addConverter(toStringDate);

//        modelMapper.getTypeMap(String.class, Date.class).setProvider(localDateProvider);

        modelMapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);

    }

    private ModuleHelper() {

    }

    public static <D, T> D map(final T entity, Class<D> outClass) {

        return modelMapper.map(entity, outClass);

    }

    public static <D, T> List<D> mapAll(final Collection<T> entityList, Class<D> outCLass) {

        return entityList.stream()

                .map(entity -> map(entity, outCLass))

                .collect(Collectors.toList());

    }

    public static <S, D> D map(final S source, D destination) {

        modelMapper.map(source, destination);

        return destination;

    }

}
