您可以使用apache StringUtils使用左边界和右边界来切割字符串。您的左边界是清晰的“ return
{”，但我不确定您的右边界（JSON有效负载之后的字符串）。在下面的示例中，我使用]}作为分隔符来剪切JSON有效负载。使用prev.getResponseDataAsString（）将响应有效负载拉为字符串。
import org.apache.commons.lang3.StringUtils;import net.minidev.json.parser.JSONParser;import net.minidev.json.JSONObject;import net.minidev.json.JSONArray;String sInputString = "return {"items":[{"STANDARDRATEFORMAT":"0.00","ASSIGNED_HRS":0,"RESOURCE_NAME":"#Buddhika ","COST":"0.00","PERCENTASSIGNED":"100.00","EMAIL":"Buddhika75@mspblank.com","AVAILABLEFROM":"10-May-2011","ALLOCATED_HRS":"1872.00","RESOURCE_ID":36197221,"AVAILABLETO":"31-Mar-2012","calendar":{"exceptions":{},"weekDayHours":{}}}]}";//String sInputString = prev.getResponseDataAsString();try { // Use StringUtils to cut the string between the two String sCutString = StringUtils.substringBetween(sInputString, "return {"items", "]}"); String sFinalString = "{"items" + sCutString + "]}"; log.info("sFinalString=" + sFinalString); // Use JSonParser to parse the JSON JSonParser parser = new JSonParser(JSONParser.ACCEPT_NON_QUOTE|JSONParser.ACCEPT_SIMPLE_QUOTE); JSonObject rootObject = (JSONObject) parser.parse(sFinalString); //JSonObject rootObject = (JSONObject) parser.parse(prev.getResponseDataAsString()); JSonArray jResourceArray = (JSONArray) rootObject.get("items"); for (int i=0; i < jResourceArray.size(); i++) { log.info(jResourceArray.get(i).toString()); // You can access individual elements using this log.info("RESOURCE_ID=" + jResourceArray.get(i).get("RESOURCE_ID")); }}catch ( Exception ex) { log.info("Exception.." + ex);}
