modelMapper使用,将数据库查询对象直接转成DTO对象
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;
}
}
