scala对象转json字符串

1.样例类转换成为JSON字符串

1. pom.xml文件

   <dependency>
       <groupId>org.json4s</groupId>
       <artifactId>json4s-native_2.11</artifactId>
       <version>3.5.4</version>
   </dependency>
   

2. 代码操作

   import org.json4s.native.Serialization
   implicit val formats = org.json4s.DefaultFormats
   val orderInfoJson: String = Serialization.write(scala对象)
   

2.scala迭代器类型转成JSON字符串

1. pom.xml文件

   <dependency>
   	<groupId>org.json4s</groupId>
   	<artifactId>json4s-native_2.11</artifactId>
   	<version>3.2.11</version>
   </dependency>
   

2. 代码操作

   import org.json4s.native.JsonMethods
   import org.json4s.JsonDSL._
   JsonMethods.compact(JsonMethods.render(迭代器对象))
