这个主要是因为T extends Serializable这样写之后,data字段的类型就是java.io.Serializable,在读取data字段的值的时候,就是通过readObject(in, java.io.Serializable.class)

最终就会执行到Hessian2Input#readObject(Class expectedClass, Class<?>... expectedTypes)中

  case 'H': {
      // 最终获取的是ObjectDeserializer
      Deserializer reader = findSerializerFactory().getDeserializer(expectedClass);

      boolean keyValuePair = expectedTypes != null && expectedTypes.length == 2;
      // ObjectDeserializer并没有实现readMap,所以最终调用的AbstractDeserializer#readMap,该方法最终都会抛出错误
      return reader.readMap(this
              , keyValuePair ? expectedTypes[0] : null
              , keyValuePair ? expectedTypes[1] : null);
  }

我不懂的是为啥这里是reader.readMap而不是reader.readObject,如果是readObject的话这个问题应该就不存在了

我觉得这应该是hessian2的bug

如果不设计文件传输的场景,建议用其他的序列化方式把
