### Pre-check - [X] I am sure that all the content I provide is in English. ### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>3.2.10</version> </dependency> JDK：21 ### Steps to reproduce this issue 在A服务中返回一个Map<Integer, UserLevelVO>结果，A服务是正常的，但是B服务拿到的是只有第一个参数不为null，其他后面的参数都为null。有个奇怪的现象是如果我在实体类里面加一个private List<UserLevelVO> userLevelList; 那么B服务可以拿到正常的数据。现在我把dubbo的序列化配置成下面这个，不用加userLevelList参数也能拿到正常的参数。请问一下，这个问题是什么原因导致的，为什么只有第一个参数不会为null，后面的都会为null？ provider: prefer-serialization: hessian2,fastjson2 @Getter @Setter @SuperBuilder @NoArgsConstructor @Accessors(chain = true) public class GetUserLevelRsp extends DataMapVO<Integer, UserLevelVO> { @Serial private static final long serialVersionUID = 8751433520190224903L; // private List<UserLevelVO> userLevelList; } @Getter @Setter @SuperBuilder @NoArgsConstructor @AllArgsConstructor @Accessors(chain = true) public class DataMapVO<I, T> implements AbstractBasicVO { @Serial private static final long serialVersionUID = 7798404966291352969L; @JsonInclude(JsonInclude.Include.NON_NULL) private Map<I, T> voMap = new HashMap<>(); /** * 根据Id获取视图 */ @JsonIgnore public T getVO(I infoId) { return voMap.get(infoId); } /** * 获取用户 */ @JsonIgnore public T getVO() { return voMap.values().stream().findFirst().orElse(null); } /** * 获取视图列表 */ @JsonIgnore public List<T> getVOList() { return new ArrayList<>(voMap.values()); } @JsonIgnore public <R extends DataMapVO> R setVOMap(Map<I, T> voMap) { this.voMap = voMap; return (R)this; } } @Override @ServiceApi public GetUserLevelRsp getUserLevel(GetUserLevelReq req) { List<Integer> idList = req.getIdList(); if (idList.isEmpty()) { return new GetUserLevelRsp(); } GetUserLevelRsp levelRsp = new GetUserLevelRsp(); Map<Integer, UserLevelVO> map = new HashMap<>(); idList.stream().distinct().forEach(id -> { map.put(id, UserLevelVO.builder().glamourLevel(glamourLevel).richLevel(richLevel).build()); }); levelRsp.setVOMap(map); // levelRsp.setUserLevelList(map.values().stream().collect(Collectors.toList())); log.error("levelRsp = {}", ToolFastJson.objectToJson(levelRsp)); return levelRsp; }   ### What you expected to happen 是不是dubbo的序列化哪里有问题？ ### Anything else _No response_ ### Are you willing to submit a pull request to fix on your own? - [X] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
