Orika - 将对象（源）映射到对象的集合（集合）（目标）

Question

  

我有以下课程。

// Source Classes
class SourceEmployer 
{
    private EmployerDetail employerDetail;

    // getters/setters
}
class EmployerDetail
{
   private String name;

   // getters/setters
}

  // Destination Classes
class DestApplication 
{
    private Employment employment;

    // getters/setters
}

class Employment 
{
    private Set<EmployerDetails> employerDetails;

    // getters/setters
}

class EmployerDetails
{
   private String employerName;

   // getters/setters
}

  // Some Mapping configuration

   public DestApplication getOrikaMapping(SourceEmployer source, DestApplication destination)
    {
        MapperFacade mapper;
        MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
        mapperFactory.classMap(source.getClass(), destination.getClass())
                .field("employerDetail.name",
                        "employment.employerDetails{employerName}")
                .byDefault()
                .register();
        mapper = mapperFactory.getMapperFacade();
        DestApplication dto = mapper.map(source, DestApplication.class);
        return dto;
    }

当执行上面的代码时，我遇到了以下例外......

它似乎是一个Orika bug，我在这里报告：https://github.com/orika-mapper/orika/issues/104。

为映射器生成的字节码不正确，首先声明null变量，然后尝试访问它。
