Groovy JSON 處理

生成JSON字串

class JSONHandle {
    static void main(String[] args){
        def jsonStr = JsonOutput.toJson([name:'assad',city:'Guangzhou',id:'237819321']);
        println(jsonStr);    
        //output:{"name":"assad","city":"Guangzhou","id":"237819321"}
    }
}
 

解析JSON字串

class JSONHandle {
    static void main(String[] args){

        def jsonStr = '{"name":"assad","city":"Guangzhou","id":"237819321"}';    //json字串
        def jsonSlurper = new JsonSlurper();                //建立 JsonSlurper 物件並解析文字
        def student = jsonSlurper.parseText(jsonStr);

        def name = student.name;             //通過訪問物件屬性的方式訪問json元素；
        def city = student.city;
    }
}
