英文:
Spring Boot Neo4j partial update operation
问题
更新Spring Boot应用程序中的Neo4j数据库中的节点的最聪明方法是什么。
我会收到一个像这样的对象：
{
"name":"name",
"surname":"surname",
"likes":[
{
"name":"football",
"score":9
},
{
"name":"golf",
"score":6
}
]
}
我想使用同样的对象，但只选择一些值，例如：
{
"surname":"otherSurname"
}
并实现以下效果：
{
"name":"name",
"surname":"otherSurname",
"likes":[
{
"name":"football",
"score":9
},
{
"name":"golf",
"score":6
}
]
}
或者添加一些内容到列表中：
"likes": [
{
"name": "basketball",
"score": 7
}
]
有没有办法做到这一点？
起初，我尝试删除节点并保存一个新节点，但每次我都没有获得整个对象。
英文:
What is the smartest way to update nodes partially in Spring Boot application with Neo4j db.
I will get an object like this:
{
"name":"name",
"surname":"surname",
"likes":[
{
"name":"football",
"score":9
},
{
"name":"golf",
"score":6
}
]
}
I would like to use same object but with some choosen values for example:
{
"surname":"otherSurname"
}
and achive something like this:
{
"name":"name",
"surname":"otherSurname",
"likes":[
{
"name":"football",
"score":9
},
{
"name":"golf",
"score":6
}
]
}
Or add something to list:
"likes": [
{
"name": "basketball",
"score": 7
}
]
Is any way to do this?
At first I tried to delete the node and save a new one, but each time I don't get the whole object

如果您不首先删除节点，而是重新保存整个对象，它应该会更新新的值并添加/删除数据库中没有的内容。
如果您只想选择某些属性保存在对象或领域类中，我会编写一个自定义查询，仅设置更新/新值，然后保留其他部分。
我正在为这种情况制作一些示例，但目前还没有可以演示的内容。
英文:
If you don't delete the node first and, instead, re-save the whole object, it should update new values and add/remove things that aren't in the database.
If you only want to pick and choose certain properties to save out of an object or domain class, I would write a custom query to set the updated/new values only and leave the rest.
I'm working on some examples for scenarios like this, but I don't have anything to send for demonstrating just yet.
