Spring data couchbase 4.0.0 - Save Object with list is always empty
问题
我目前正在将我的项目升级到 Spring Data Couchbase 4.0.0，但是在我想保存带有列表的对象时遇到了问题。我不确定我的代码中是否有错误，或者这是否是一个 bug，但我找不到任何关于这个问题的信息。
我有一个简单的用户对象，带有一个属性 role，它是一个 ArrayList
user.getRole().add("ROLE_USER");
user.getRole().forEach(System.out::println);
// 将用户保存到数据库
this.userService.save(user);
对象 user 被正确保存，所有属性都被保存，除了列表。注释列表是空的，true 是正确的，角色为空，但没有数据。
"comment": {
"empty": true
},
"role": {
"empty": false
}
新版本中是否有什么变化，还是我做错了什么？

I am currently upgrading my project to spring data couchbase 4.0.0 and I am now experiencing problems when I want to save a Object with a list. I am not sure if there is an error in my code or this is a bug, but I could not find any informationen about this.
I have a simple user object with an attribute role, which is an ArrayList<String>. The user gets an role added and the save method is called. The interface userService Repository extends PagingAndSortingRepository and the normal save method is called, which worked before 4.0.0 perfectly.
user.getRole().add("ROLE_USER");
user.getRole().forEach(System.out::println);
//Save User in DB
this.userService.save(user);
The Object user is saved correctly, all attributes are saved except the List. The comment list was empty and the true is also correct, role is empty false but without data.
"comment": {
"empty": true
},
"role": {
"empty": false
},
Did something change with the new version or I am doing something wrong?

新版本的 Spring Data Couchbase 4.0.0 存在与保存列表/映射相关的错误。
根据文档，Spring Data Couchbase 应支持保存带有列表和组合对象的文档，但实际上并不支持。
