JSON JDK13 JDK1.3 JSON对象转换 jdk1.3对象嵌套转换
因为JDK1.3/1.4不支持泛型，所以写法比支持对象嵌套的要复杂，附件是自己研究的一个例子 /* ===========================JSON字符串转换为Java Object===============================*/ String sibill = ""; sibill = "{\"blno\":\"123\",\"cutofftime\":\"2011-1-12\",\"vsl\":\"vsl\",\"voy\":\"voy\",\"port\":\"port\",\"consigneename\":\"consigneename\",\"consigneeaddress\":\"consigneeaddress\",\"consigneecityc\":\"consigneecitycountry\","+ "\"cntr\":[{\"cntrno\":\"111111\",\"cl\":\"拼箱\",\"sealnum\":\"sealnum1\",\"size\":\"40\",\"box\":\"H1\",\"cgo\":[{\"cgonum\":\"cgonum11\",\"cgoweight\":\"cgoweight1\",\"cgosize\":\"cgosize1\",\"cgohscode\":\"cgohscode1\",\"cgoowner\":\"cgoowner1\"}]},"+ "{\"cntrno\":\"222222\",\"cl\":\"整箱\",\"sealnum\":\"sealnum2\",\"size\":\"48\",\"box\":\"G1\",\"cgo\":[{\"cgonum\":\"cgonum21\",\"cgoweight\":\"cgoweight1\",\"cgosize\":\"cgosize1\",\"cgohscode\":\"cgohscode1\",\"cgoowner\":\"cgoowner1\"},{\"cgonum\":\"cgonum22\",\"cgoweight\":\"cgoweight2\",\"cgosize\":\"cgosize2\",\"cgohscode\":\"cgohscode2\",\"cgoowner\":\"cgoowner2\"}]}]"+ "}"; /* 第一步 (直接转换为Java Object) */ SiBillBean sibillbean = (SiBillBean)JSONObject.toBean(JSONObject.fromObject(sibill),SiBillBean.class); /* 第二布 (取出嵌套对象属性值) */ JSONArray arrCntr = sibillbean.getCntr(); for (int i = 0; i < arrCntr.size(); i++) { JSONObject cntr = (JSONObject)arrCntr.get(i); CntrBean cntrBean = (CntrBean)JSONObject.toBean(cntr,CntrBean.class); System.out.println(cntrBean); JSONArray arrCgo = cntrBean.getCgo(); for (int j = 0; j < arrCgo.size(); j++) { JSONObject cgo = (JSONObject)arrCgo.get(j); CgoBean cgoBean = (CgoBean)JSONObject.toBean(cgo,CgoBean.class); System.out.println(cgoBean); } } /* 第二布 end */ /* ===========================Java Object转换为JSON字符串===============================*/ //CGO 1/2/3 CgoBean cgoBean1 = new CgoBean(); cgoBean1.setCgonum("cgo11"); CgoBean cgoBean2 = new CgoBean(); cgoBean2.setCgonum("cgo21"); CgoBean cgoBean3 = new CgoBean(); cgoBean3.setCgonum("cgo22"); //CNTR1 CntrBean cntrBean1 = new CntrBean(); cntrBean1.setCntrno("cntr1"); JSONArray jsonArrayCntr1 = new JSONArray(); jsonArrayCntr1.add(0, cgoBean1); cntrBean1.setCgo(jsonArrayCntr1); //CNTR2 CntrBean cntrBean2 = new CntrBean(); cntrBean2.setCntrno("cntr2"); JSONArray jsonArrayCntr2 = new JSONArray(); jsonArrayCntr2.add(0, cgoBean2); jsonArrayCntr2.add(1, cgoBean3); cntrBean2.setCgo(jsonArrayCntr2); //SIBILL SiBillBean sibillb = new SiBillBean(); sibillb.setBlno("COSU 123456789"); JSONArray jsonArraySiBill = new JSONArray(); jsonArraySiBill.add(0, cntrBean1); jsonArraySiBill.add(1, cntrBean2); sibillb.setCntr(jsonArraySiBill); System.out.println(JSONObject.fromObject(sibillb));
