Spring @RequestBody包含不同类型的列表（但接口相同）

您应该使用Jackson注释

@JsonTypeInfo

@JsonSubTypes

Animal

@JsonTypeInfo(use = Id.NAME, include = As.PROPERTY, property = "type")@JsonSubTypes({@JsonSubTypes.Type(value = Dog.class, name = "Dog"),        @JsonSubTypes.Type(value = Cat.class, name = "Cat")})public abstract class Animal {}
