JSON 使用
import com.google.gson.JsonObject;
使用方法: google gson
Gson gson = new GsonBuilder().enableComplexMapKeySerialization().create(); // 解决特殊字符串被转义 Gson gson = new GsonBuilder().setPrettyPrinting().disableHtmlEscaping().create(); List<Map<String,Object>> jsonList = new ArrayList<Map<String,Object>>(); Map<String,Object> jsonMap = new HashMap<String,Object>(); jsonMap.put("fileName", item.getFieldName()); jsonMap.put("newFileUrl", saveUrl+newFileName); jsonMap.put("oldName", oldName); jsonMap.put("fileSize", SysUtil.formatTwo(Double.valueOf(fileSize/1024))); jsonList.add(jsonMap); Map<String,Object> jsonMap = new HashMap<String,Object>(); jsonMap.put("formIndex", request.getParameter("formIndex")); jsonMap.put("formId", request.getParameter("formId")); jsonMap.put("faction", request.getParameter("faction")); jsonMap.put("error", "0"); jsonMap.put("files", jsonList); String jsonStr = gson.toJson(jsonMap);
import org.json.simple.JSONObject;
使用方法:
JSONArray objs = new JSONArray(); JSONObject obj = new JSONObject(); obj.put("fieldName", item.getFieldName()); obj.put("newFileUrl", saveUrl + newFileName); obj.put("oldname", oldName); obj.put("fileSize", SysUtil.formatTwo(Double.valueOf(fileSize/1024))); objs.add(obj); JSONObject result = new JSONObject(); result.put("error", 0); result.put("files", objs); result.put("formId", request.getParameter("formId")); result.put("formIndex", request.getParameter("formIndex")); result.put("faction", request.getParameter("faction")); result.toJSONString());
