Spring Boot MVC-不支持内容类型'application / json; charset = UTF-8'

您不能将

Collection, Map, Array or enumeration

用作

@JsonBackReference

。

请参阅链接：[https](https://fasterxml.github.io/jackson-

annotations/javadoc/2.2.0/com/fasterxml/jackson/annotation/JsonBackReference.html)

//fasterxml.github.io/jackson-
annotations/javadoc/2.2.0/com/fasterxml/jackson/annotation/JsonBackReference.html
。

尝试互换

@JsonBackReference

和

@JsonManagedReference

。它应该工作。
