在Scala中使用fasterxml.jackson验证嵌套的case类,可以通过以下步骤实现:
libraryDependencies += "com.fasterxml.jackson.core" % "jackson-databind" % "2.12.5"
{
"name": "John",
"age": 30,
"address": {
"street": "123 Main St",
"city": "New York"
}
}
在Scala中,可以定义对应的嵌套case类如下:
case class Address(street: String, city: String)
case class Person(name: String, age: Int, address: Address)
import com.fasterxml.jackson.databind.ObjectMapper
val json = """{
"name": "John",
"age": 30,
"address": {
"street": "123 Main St",
"city": "New York"
}
}"""
val mapper = new ObjectMapper()
val person = mapper.readValue(json, classOf[Person])
// 验证嵌套的case类
val address = person.address
println(s"Street: ${address.street}")
println(s"City: ${address.city}")
在上述代码中,我们使用ObjectMapper类将JSON数据反序列化为Person对象。然后,我们可以通过访问嵌套的case类属性来验证数据的正确性。
请注意,以上答案仅供参考,具体实现方式可能因项目环境和需求而异。
