如何在JavaScript中将自定义对象的arraylist转换为json

Question

I have a (java.util.List) List returned to the jag. That should be printed as a json .

   var storeForum = Packages.org.wso2.carbon.forum.registry.RegistryForumManager;

   var forum = new storeForum();

   var start = request.getParameter('start');
   var count = request.getParameter('count');

   var array =forum.fetchForumTopics(start,count, tenantDomainsArr, -1234, user.username);

forum.fetchForumTopics method returns

    List<customOjbect> 

How to print it as a json. Didn't find anything useful on net.

Answer 1

i'm not quite sure what a jag is - but you can use JSON.stringify() to convert an array of pairs or values into a JSON object

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

JSON.stringify(array) 

Answer 2

由于这是一个Java对象，您是否可以使用可以将相应的Object转换为JSON的Java模块尝试进行此转换？。您可能必须将该模块导入.jag（jaggery）文件。
