Java中如何操作JSON格式的字符串
1. 首先需要一个类支持 JSONObject类,该类需要外部JAR包支持,下面是下载地址
jettison-1.0.jar包下载地址：http://www.kuaipan.cn/file/id_21487635482542624.htm
2. 下面在代码中演示如何用
1 import org.codehaus.jettison.json.JSONException; 2 import org.codehaus.jettison.json.JSONObject; 3 4 public class HelloWorldTest { 5 public static void main(String[] args) { 6 String jsonStr = "{\"b_action\":\"xts.run\",\"m\":\"portal/report-viewer.xts\",\"method\":\"execute\"," 7 + "\"ui.action\":\"run\",\"ui.tool\":\"CognosViewer\",\"ui.object\":\"/content/package[@name='zjfx_bdgc']/report[@name='a']\"," 8 + "\"ZTBM\":\"000010000200001000010000100001\",\"MBBM\":\"001\",\"p_d\":\"2011010000100001\"," 9 + "\"run.prompt\":\"false\",\"ZBYQ_DJ\":\"1111\",\"BDGC_DYDJ\":\"22222\",\"BDGC_JSXZ\":\"01\"," 10 + "\"JSZB_BDZXS\":\"01,02,03\",\"PDXS_GYC_PDZZXH\":\"02\",\"ZBYQ_BQTS1\":\"1\",\"ZBYQ_BQTS2\":\"2\"," 11 + "\"ZBYQ_DTRL1\":\"3\",\"ZBYQ_DTRL2\":\"4\",\"JGJS_JTTZ1\":\"5\"," 12 + "\"JGJS_JTTZ2\":\"6\",\"btnsearch\":\"查询\",\"btnreset\":\"重置\"}"; 13 14 try { 15 JSONObject obj = new JSONObject(jsonStr); 16 String b_action = (String)obj.get("b_action"); 17 System.out.println(b_action); 18 } catch (JSONException e) { 19 e.printStackTrace(); 20 } 21 } 22 }
