java解析JSON

在www.json.org上公布了很多Java下的json解析工具，其中json-lib比较简单，下面源代码是解析和构造JSON的演示程序。
这是使用json-lib的程序：

package com.jshx.httptransfer.utils;

import java.util.HashMap;
import java.util.Map;

import net.sf.json.JSONObject;

public class test {
	public static void main(String[] args) {
		String json ="{\"name\":\"reiz\"}";
		JSONObject jsonObj = JSONObject.fromObject(json);
		String name = jsonObj.getString("name");
		
		jsonObj.put("initial", name.substring(0, 1).toUpperCase());
		String[] likes = new String[] { "JavaScript", "Skiing", "Apple Pie" };
		jsonObj.put("likes", likes);
		
		Map<String, String> ingredients = new HashMap<String, String>();
		ingredients.put("apples", "3kg");
		ingredients.put("sugar", "1kg");
		ingredients.put("pastry", "2.4kg");
		ingredients.put("bestEaten", "outdoors");
		jsonObj.put("ingredients",ingredients);
		    
		System.out.println(jsonObj);
		
		Map<String, String> tt = jsonObj.getJSONObject("ingredients");
		System.out.println(tt.get("apples"));
	}
}

要依赖ezmorph和commons的lang、logging、beanutils、collections等组件。

// 填写需要过滤的JSON字段
            String[] excludes = new String[] { "dbTableName" };
            List<PropertyFilter> filters = new ArrayList();
            filters.add(new IgnoreNullFieldPropertyFilter());
//JSON json = JSONSerializer
                    .toJSON(resultMap, JsonUtils.configJson(excludes, filters, "yyyy-MM-dd HH:mm:ss"));
JSONObject detailArray = JSONObject.fromObject(jshxWorkReply,JsonUtils.configJson(excludes, filters, "yyyy-MM-dd HH:mm:ss"));
