我正在使用Spring、Gradle和Oracle开发一个Spring项目，在这个项目中，我使用DozerBeanMapper将实体映射到DTO，反之亦然，我不对Dozer使用xml，只使用Java配置：

代码语言：javascript
复制
@Slf4j
@Configuration
public class DozerConfig {
    @Bean
    public DozerBeanMapper getDozerMapper() {
        log.info("Initializing DozerBeanMapper bean");
        return new DozerBeanMapper();
    }
}

另外，为了清晰起见，我已经显式地配置了所有必须映射的字段，尽管它们都有相同的名称。例如，我的客户映射程序：

代码语言：javascript
复制
@Slf4j
@Component
public class ClientMapper extends BaseMapper {

    private BeanMappingBuilder builder = new BeanMappingBuilder() {
        @Override
        protected void configure() {
            mapping(Client.class, ClientDTO.class)
                    .fields("id", "id")
                    .fields("name", "name")
                    .fields("midName", "midName")
                    .fields("surname", "surname")
                    .exclude("password")
                    .fields("phone", "phone")
                    .fields("email", "email")
                    .fields("address", "address")
                    .fields("idCardNumber", "idCardNumber")
                    .fields("idCardIssueDate", "idCardIssueDate")
                    .fields("idCardExpirationDate", "idCardExpirationDate")
                    .fields("bankAccounts", "bankAccounts")
                    .fields("accountManager", "accountManager")
                    .fields("debitCardNumber", "debitCardNumber")
                    .fields("creditCardNumber", "creditCardNumber")
                    .fields("dateCreated", "dateCreated")
                    .fields("dateUpdated", "dateUpdated");
        }
    };

    @Autowired
    public ClientMapper(DozerBeanMapper mapper) {
        super(mapper);
        mapper.addMapping(builder);
    }

    public ClientDTO toDto(Client entity) {
        log.info("Mapping Client entity to DTO");
        return mapper.map(entity, ClientDTO.class);
    }

    public Client toEntity(ClientDTO dto) {
        log.info("Mapping Client DTO to entity");
        return mapper.map(dto, Client.class);
    }

    public List<ClientDTO> toDtos(List<Client> entities) {
        log.info("Mapping Client entities to DTOs");
        return entities.stream()
                       .map(entity -> toDto(entity))
                       .collect(Collectors.toList());
    }

    public List<Client> toEntities(List<ClientDTO> dtos) {
        log.info("Mapping Client DTOs to entities");
        return dtos.stream()
                   .map(dto -> toEntity(dto))
                   .collect(Collectors.toList());
    }

    public EmployeeDTO toEmployeeDto(Employee entity) {
        log.info("Mapping Employee entity to DTO");
        return mapper.map(entity, EmployeeDTO.class);
    }

    public Employee toEmployeeEntity(EmployeeDTO dto) {
        log.info("Mapping Employee DTO to entity");
        return mapper.map(dto, Employee.class);
    }

    public List<EmployeeDTO> toEmployeeDtos(List<Employee> entities) {
        log.info("Mapping Employee entities to DTOs");
        return entities.stream()
                .map(entity -> toEmployeeDto(entity))
                .collect(Collectors.toList());
    }

    public List<Employee> toEmployeeEntities(List<EmployeeDTO> dtos) {
        log.info("Mapping Employee DTOs to entities");
        return dtos.stream()
                .map(dto -> toEmployeeEntity(dto))
                .collect(Collectors.toList());
    }
}

尽管如此，我还是得到了以下例外：

似乎Dozer正在试图找到一些xml conffig文件，考虑到这一点：

"oracle.xml.jaxp.JXDocumentBuilderFactory.setAttribute(JXDocumentBuilderFactory.java:289)“

它似乎正在搜索一个xml验证模式(看看下面图片中的var1 )：

​

​

在启动应用程序时，我在IntelliJ控制台中看到了以下内容：

代码语言：javascript
复制
Trying to find Dozer configuration file: dozer.properties
2020-12-23 11:46:09.855  WARN 17488 --- [  restartedMain] org.dozer.config.GlobalSettings: Dozer configuration file not found: dozer.properties.  Using defaults for all Dozer global properties.

也许我必须搜索dozer.properties并了解如何使它看起来像Java？

有人能帮帮我吗？我在网上寻找了一些解决方案，但仍然没有找到合适的解决方案。我是Dozer的新手，我以前用过Mapstruct吗？

您可以尝试我的豆刀自动生成dto文件。它将有一个read方法将实体转换为dto。虽然没有从dto到实体的转换，但我认为在大多数情况下您不需要它。

代码语言：javascript
复制
@ViewOf(value = Client.class, genName = "ClientDto", includePattern = ".*")
class ClientDtoConfiguration {}

然后，它将生成一个名为"ClientDto“的dto类，其中包含了客户端的所有属性。

代码语言：javascript
复制
Client client = ...
ClientDto clientDto = ClientDto.read(client);
List<Client> clients = ...
List<ClientDto> clientDtos = ClientDto.read(clients);

然后序列化dtos而不是实体。
