ModelMapper-已存在映射-两种配置

Question

我有两个类使用ModelMapper将实体转换为DTO。在每个类中，我都在类的构造函数中配置了ModelMapper，以避免将所有关系转换为DTO并获得StackOverflow Error。

公司服务impl

private ModelMapper modelMapper;

@Autowired
public CompanyServiceImpl(ModelMapper modelMapper) {
    this.modelMapper = modelMapper;

    modelMapper.addMappings(skipCompanyServiceFieldsMap);
    modelMapper.addMappings(skipCompanyServiceModuleFieldsMap);
}

PropertyMap<CompanyServiceModule, CompanyServiceModuleDTO> skipCompanyServiceModuleFieldsMap = new PropertyMap<CompanyServiceModule, CompanyServiceModuleDTO>() {
    @Override
    protected void configure() {
        // Tells ModelMapper to NOT populate back references
        skip(destination.getCompanyService());
        skip(destination.getServiceModule().getCompanyServiceModules());
        skip(destination.getServiceModule().getService());
        skip(destination.getServiceModule().getServiceModuleLanguages());
        skip(destination.getServiceModule().getServiceModuleMenus());
    }
};

公司利润

private ModelMapper modelMapper;

@Autowired
public CompanyProfileImpl(ModelMapper modelMapper) {
    this.modelMapper = modelMapper;

    modelMapper.addMappings(skipCompanyProfileFieldsMap);
    modelMapper.addMappings(skipCompanyProfileModuleFieldsMap);
    modelMapper.addMappings(skipCompanyProfileServiceModuleFieldsMap);
}

PropertyMap<CompanyServiceModule, CompanyServiceModuleDTO> skipCompanyProfileServiceModuleFieldsMap = new PropertyMap<CompanyServiceModule, CompanyServiceModuleDTO>() {
    @Override
    protected void configure() {
        // Tells ModelMapper to NOT populate back references
        skip(destination.getCompanyProfileModules());
        skip(destination.getServiceModule());
        skip(destination.getCompanyService());
    }
};

当我运行应用程序时，我得到一个错误：

com的映射已存在。特写国际。批准dtos。公司服务模块化。setCompanyService（）。

如何为ModelMapper提供两个配置，每个配置都特定于所实现的服务？因为在一种情况下，带来一些关系是有意义的，而在另一种情况下，没有。

我将类的实例化更改为构造函数，而不是让Spring实例化并作为单例处理。

private ModelMapper modelMapper;

public CompanyProfileImpl() {
    // Necessary to not get in conflict with others
    this.modelMapper = new ModelMapper();

    modelMapper.addMappings(skipCompanyProfileFieldsMap);
    modelMapper.addMappings(skipCompanyProfileModuleFieldsMap);
    modelMapper.addMappings(skipCompanyServiceModuleFieldsMap);
}
