[GitHub] [dubbo] HelloToGithub opened a new issue, #11775: serialization配置fastjson2 Arrays.asList创建的集合对象 接收时对象会被解析成HashMap

HelloToGithub opened a new issue, #11775:
URL: https://github.com/apache/dubbo/issues/11775

   <!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy -->
   
   <!-- For all design discussions please continue. -->
   使用官方dubbo-example 
   1、dubbo 3.1.7
   2、serialization 配置为fastjson2
   对象包含集合 使用Arrays.asList创建对象的传输的时候 服务接收的时候会被解析成HashMap 使用 new ArrayList<>()不会有问题
   例子如下：
   Task,class  run
   `        ParamsDTO paramsDTO = new ParamsDTO();
           ParamsItemDTO paramsItemDTO = new ParamsItemDTO();
           paramsItemDTO.setA("aaa");
           paramsDTO.setParamsItems(Arrays.asList(paramsItemDTO));
           demoService.sayHello(paramsDTO);
   //        List<ParamsItemDTO> a = new ArrayList<>();
   //        a.add(paramsItemDTO);
   //        paramsDTO.setParamsItems(a);
   //        demoService.sayHello(paramsDTO);
   `
   ParamsDTO 
   `@Data
   public class ParamsDTO implements Serializable {
       private List<ParamsItemDTO> paramsItems;
   
   }`
   
   ParamsItemDTO 
   `@Data
   public class ParamsItemDTO implements Serializable {
   
       private String a;
   }
   `

   I tested, maybe it's the problem with fastjson2.
   `com.alibaba.fastjson2.JSONB#parseObject()`

   @wenshao 温老师，我不知道您在2.0.25上做了什么修复改动，可以分享吗？针对此问题并未生效。
   我测试和验证了这个问题，感觉应该在写入JSONWriter或者读取时FieldReader做改动。
   1）代码在处理Arrays.ArrayList和普通ArrayList时，序列化ArrayList并没有写类名，但是Arrays.ArrayList当作普通类写入类名，读取时就会当作普通Object处理。
   这里我想到的解决方案是：**把所有List的实现都不写类名序列化**。我试了下可以生效。
   2）代码在反序列化时，asm生成的代码中，处理Arrays.ArrayList字段，当作普通JsonObject处理，所以专成了HashMap。
   这个我想到的解决方案是：**Arrays.ArrayList不使用autoType处理，由他自己的itemReader处理**。
   我试了可以生效，但是这个改动比较复杂，我把握不住全局。
   期待跟温老师更进一步交流😀。
