使用Jackson将Map转换为JsonParser [英] Convert Map to JsonParser using Jackson

问题描述

我想利用Jackson库的JsonParser API类。但是，构建一个json字符串构建器对我来说非常繁琐。所以我使用Map来包含我的Json对象的值。

I would like to take advantage of the JsonParser API class of the Jackson library. However, it is quite tedious for me to build a json string builder. So I made use of a Map to contain the values for my Json object.

   Map<String,Object> myMainMap = new HashMap<String,Object>();
   Map<String,String> myMap = new HashMap<String,String>();
   myMap.put("node1","value1");
   myMap.put("node2","value2");
   myMainMap.put("rootNode",myMap);

如何将此地图转换为org.codehaus.jackson.JsonParser以便我可以利用可用于此API的方法？

How do I convert this Map into a org.codehaus.jackson.JsonParser so that I can take advantage of the methods available for this API?

推荐答案

ObjectMapper mapper = new ObjectMapper();
System.out.println(mapper.writeValueAsString(myMap) );
