Scala解析Json字符串的实例详解
Scala解析Json字符串的实例详解
1. 添加相应依赖
Json解析工具使用的 json-smart,曾经对比过Java的fastjson、gson。Scala的json4s、lift-json。其中 json-smart 解析速度是最快的。
<dependency>
<groupId>net.minidev</groupId>
<artifactId>json-smart</artifactId>
<version>2.3</version>
</dependency>2. Scala代码
package Test
import java.util
import net.minidev.json.JSONObject
import net.minidev.json.parser.JSONParser
import scala.collection.JavaConversions._
import scala.collection.mutable
import scala.util.parsing.json.JSON
/**

object Test {
def main(args: Array[String]): Unit = {
val str2 = "{\"name\":\"jeemy\",\"age\":25,\"phone\":\"18810919225\"}"
val jsonParser = new JSONParser()
val jsonObj: JSONObject = jsonParser.parse(str2).asInstanceOf[JSONObject]
val name = jsonObj.get("name").toString
println(name)
val jsonKey = jsonObj.keySet()
val iter = jsonKey.iterator
while (iter.hasNext) {
val instance = iter.next()
val value = jsonObj.get(instance).toString
println("key: " + instance + " value:" + value)
}
}
