尝试使用spring的Mapper注释功能时,我遇到了一些困难。我想使用映射器来映射java中的Map对象,如下所示:

HostCounters:

@Data
@NoArgsConstructor
@AllArgsConstructor
public class HostsCounters {
    private Map<String,Map<String,Long>> hostsList;
}


映射器:

@Mapper(componentModel = "spring")
public interface ResponseMapper {
    GeneralResponse toResponse(SevCount sevCount, HostsCounters hostsList, List<RegDAO> Reg);
}


一般响应:

@Data
@NoArgsConstructor
public class GeneralResponse {
    private List<RegDAO> Reg;
    private HostsCounters hostsList;
    private SevCount sevCount;
}


错误:


  无法映射属性
  “ java.util.Map>
  hostsList“到” HostsCounters hostsList“。考虑到
  声明/实现映射方法

最佳答案

只需使用:

@Mapping(source = "hostsList", target = "hostsList")
GeneralResponse toResponse(SevCount sevCount, HostsCounters hostsList, List<RegDAO> Reg);


但我强烈建议您摆脱具有不同含义的相同名称:

HostsCounters hostsList -> HostsCounters hostsLists
