java - 使用spring Mapper映射Map对象 - Java

Question

我在尝试使用 Spring 的 Mapper 注释功能时遇到一些困难。我想使用映射器来映射java中的Map对象，如下所示:

主机计数器:

@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);
}

一般回复:

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

错误:

Can't map property "java.util.Map> hostsList" to " HostsCounters hostsList". Consider to declare/implement a mapping method

Answer 1

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 主机列表 -> HostsCounters 主机列表
