【问题描述】：
我正在使用 Spring Data Rest、Gradle 和 Oracle Express DB 开发一个 Spring Boot 项目，其中我使用 DozerBeanMapper 将实体映射到 DTO，反之亦然，我没有为 Dozer 使用 xml 配置，只使用 Java 配置：
@Slf4j
@Configuration
public class DozerConfig {
@Bean
public DozerBeanMapper getDozerMapper() {
log.info("Initializing DozerBeanMapper bean");
return new DozerBeanMapper();
}
}
另外，为了清楚起见，我已经明确配置了所有必须映射的字段，尽管它们都具有相同的名称。例如我的客户端映射器：
@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，我得到以下异常：

考虑到这一点，Dozer 似乎正在尝试查找一些 xml 配置文件：
“oracle.xml.jaxp.JXDocumentBuilderFactory.setAttribute(JXDocumentBuilderFactory.java:289)”
它似乎正在寻找一个 xml 验证模式（看看下图中的var1）：
当我启动应用程序时，我刚刚在 IntelliJ 控制台中看到以下内容：
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.
可能我必须搜索 dozer.properties 并找出如何让它查找 Java 配置？
有人可以帮帮我吗？我在互联网上搜索了一些解决方案，但我仍然没有找到合适的解决方案。我是 Dozer 的新手，以前用过 Mapstruct 吗？

这是什么版本的推土机？您是否尝试过最新版本 6.5.1？
