我有 2 个对象:

@Setter
@Getter
public class Agent {
    public int userID;
    public String name;
    public boolean isVoiceRecorded;
    public boolean isScreenRecorded;
    public boolean isOnCall;
    public LocalDateTime startEventDateTime;
}
public class AgentLine {
    public int userID;
    public String name;
    public boolean isVoiceRecorded;
    public boolean isScreenRecorded;
    public boolean isOnCall;
    public String startEventDateTime;
}

我想在 AgentLine 和 Agent 之间进行映射。由于 Localdatetime 转换,我无法使用默认映射。我已经定义:

    @Bean
    ModelMapper getModelMapper() {
        ModelMapper modelMapper = new ModelMapper();
        Converter<AgentLine, Agent> orderConverter = new Converter<AgentLine, Agent>() {
            @Override
            public Agent convert(MappingContext<AgentLine, Agent> mappingContext) {
                AgentLine s = mappingContext.getSource();
                Agent d = mappingContext.getDestination();
/*                d.userID = s.userID;
                d.name = s.name;*/
                d.startEventDateTime = LocalDateTime.parse(s.startEventDateTime, DateTimeFormatter.ISO_LOCAL_DATE_TIME);
                return d;
            }
        };
        modelMapper.addConverter(orderConverter);
        return modelMapper;
    }

为了使用它:

AgentLine line;
@Autowired
private ModelMapper modelMapper;
Agent agent = modelMapper.map(line, Agent.class);

它可以工作,但我不想在转换方法中指定所有代理属性,我想指定 startEventDateTime 转换,其余属性将默认映射。

另外我试图定义:

PropertyMap<AgentLine, Agent> orderMap = new PropertyMap<AgentLine, Agent>() {
                @Override
                protected void configure() {
                    map().setName(source.name);
                }
            };
modelMapper.addMappings(orderMap);

但是,在映射中您无法处理日期转换。如果我为映射器 PropertyMap 和 Converter 定义 PropertyMap 将被忽略。

我不想在 convert 方法中指定所有 Agent 属性,我想指定 startEventDateTime 转换,其余属性将默认映射。

不要Converter用于映射复杂对象。您应该将TypeMap其用于此类目的。用于Converter自定义转换(对于您的情况StringLocalDateTime

ModelMapper modelMapper = new ModelMapper();    
Converter<String, LocalDateTime> dateTimeConverter = ctx -> ctx.getSource() == null ? null : LocalDateTime.parse(ctx.getSource(), DateTimeFormatter.ISO_LOCAL_DATE_TIME);
modelMapper.typeMap(AgentLine.class, Agent.class)
        .addMappings(mapper -> mapper.using(dateTimeConverter).map(AgentLine::getStartEventDateTime, Agent::setStartEventDateTime));
