The neo4j version is 4.4.11, and if I use spring’s save, the fields on the relationship between nodes disappear

There is a field on the relationship between the two nodes, but it disappears when I use spring’s save
And if I don’t send stationType, the relationship between these two nodes will simply disappear

I want the fields in the relationship not to disappear when I save it, and the relationship between the two nodes will not disappear if I don’t send stationType in
