JsonArray

简单说说Json数组，见如下实例：


package com.json.jsonarray;

import net.sf.json.JSONObject;

import org.apache.commons.lang.StringEscapeUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONValue;

public class JsonArrayTest {


public static void main(String[] args) {
String s = "[0,{\"1\":{\"2\":{\"3\":{\"4\":[5,{\"6\":7}]}}}}]";
Object obj = JSONValue.parse(s);
JSONArray array = (JSONArray) obj;
System.out.println(array.get(0));
System.out.println(array.get(1));

/*
*
String str = "{\"params\":[{\"field0\":\"NAME\",\"operateflag0\":\"@contain#\",\"searchcontant0\":\"北\",\"logic0\":\"and\"},   {\"field1\":\"ID\",\"operateflag1\":\"@contain#\",\"searchcontant1\":\"1\",\"logic1\":\"or\"},{\"field2\":\"SEQUENCE\",\"operateflag2\":\"@contain#\",\"searchcontant2\":\"5\"}]}";
System.out.println("接收到的字符串：" + str);
// 将json字符串转成json对象
JSONObject jb = JSONObject.fromObject(str);
// 取查询参数params,是个json数组
net.sf.json.JSONArray jsons = jb.getJSONArray("params");
int jsonLength = jsons.size();
// 对json数组进行循环

for (int i = 0; i < jsonLength; i++) {
JSONObject tempJson = JSONObject.fromObject(jsons.get(i));
System.out.println("ddd:" + tempJson);
String field = StringEscapeUtils.escapeSql(tempJson
.getString("field" + i));
String operateFlag = StringEscapeUtils.escapeSql(tempJson
.getString("operateflag" + i));
String searchContant = StringEscapeUtils.escapeSql(tempJson
.getString("searchcontant" + i));
String logic = StringEscapeUtils.escapeSql(tempJson
.getString("logic" + i));
}
*/


}
}

以上代码复制就可以运行。
