JSON转换成复合BEAN问题？

第一个JAVABEAN：
public class ResultRules {
 private String gTaskId;
 private int ulRet;
 private String execStatus;
 private int ulRetParam1;
 private int ulRetParam2;
 private int ulTaskStatus;
 private String cmdName;
 private int nNUms;
 private List<Rules> rules;

 public String getgTaskId() {
  return gTaskId;
 }

 public void setgTaskId(String gTaskId) {
  this.gTaskId = gTaskId;
 }

 public int getUlRet() {
  return ulRet;
 }

 public void setUlRet(int ulRet) {
  this.ulRet = ulRet;
 }

 public String getExecStatus() {
  return execStatus;
 }

 public void setExecStatus(String execStatus) {
  this.execStatus = execStatus;
 }

 public int getUlRetParam1() {
  return ulRetParam1;
 }

 public void setUlRetParam1(int ulRetParam1) {
  this.ulRetParam1 = ulRetParam1;
 }

 public int getUlRetParam2() {
  return ulRetParam2;
 }

 public void setUlRetParam2(int ulRetParam2) {
  this.ulRetParam2 = ulRetParam2;
 }

 public int getUlTaskStatus() {
  return ulTaskStatus;
 }

 public void setUlTaskStatus(int ulTaskStatus) {
  this.ulTaskStatus = ulTaskStatus;
 }

 public String getCmdName() {
  return cmdName;
 }

 public void setCmdName(String cmdName) {
  this.cmdName = cmdName;
 }

 public int getnNUms() {
  return nNUms;
 }

 public void setnNUms(int nNUms) {
  this.nNUms = nNUms;
 }

 public List<Rules> getRules() {
  return rules;
 }

 public void setRules(List<Rules> rules) {
  this.rules = rules;
 }

}

 

第二个JAVABEAN：

public class Rules {
 private int nSnmpTry;
 private int nSnmpVersion;
 private String szCommunity;
 private int nType;
 private int nCurrentTick;
 private String szParam;
 private String szOid;
 private int PollTime;
 private String szUpdateTime;
 private String szCreateTime;
 private String szSnmpIP;
 private int ID;
 private int nSnmpTimeOut;
 private int nSnmpPort;

 public int getnSnmpTry() {
  return nSnmpTry;
 }

 public void setnSnmpTry(int nSnmpTry) {
  this.nSnmpTry = nSnmpTry;
 }

 public int getnSnmpVersion() {
  return nSnmpVersion;
 }

 public void setnSnmpVersion(int nSnmpVersion) {
  this.nSnmpVersion = nSnmpVersion;
 }

 public String getSzCommunity() {
  return szCommunity;
 }

 public void setSzCommunity(String szCommunity) {
  this.szCommunity = szCommunity;
 }

 public int getnType() {
  return nType;
 }

 public void setnType(int nType) {
  this.nType = nType;
 }

 public int getnCurrentTick() {
  return nCurrentTick;
 }

 public void setnCurrentTick(int nCurrentTick) {
  this.nCurrentTick = nCurrentTick;
 }

 public String getSzParam() {
  return szParam;
 }

 public void setSzParam(String szParam) {
  this.szParam = szParam;
 }

 public String getSzOid() {
  return szOid;
 }

 public void setSzOid(String szOid) {
  this.szOid = szOid;
 }

 public int getPollTime() {
  return PollTime;
 }

 public void setPollTime(int pollTime) {
  PollTime = pollTime;
 }

 public String getSzUpdateTime() {
  return szUpdateTime;
 }

 public void setSzUpdateTime(String szUpdateTime) {
  this.szUpdateTime = szUpdateTime;
 }

 public String getSzCreateTime() {
  return szCreateTime;
 }

 public void setSzCreateTime(String szCreateTime) {
  this.szCreateTime = szCreateTime;
 }

 public String getSzSnmpIP() {
  return szSnmpIP;
 }

 public void setSzSnmpIP(String szSnmpIP) {
  this.szSnmpIP = szSnmpIP;
 }

 public int getID() {
  return ID;
 }

 public void setID(int iD) {
  ID = iD;
 }

 public int getnSnmpTimeOut() {
  return nSnmpTimeOut;
 }

 public void setnSnmpTimeOut(int nSnmpTimeOut) {
  this.nSnmpTimeOut = nSnmpTimeOut;
 }

 public int getnSnmpPort() {
  return nSnmpPort;
 }

 public void setnSnmpPort(int nSnmpPort) {
  this.nSnmpPort = nSnmpPort;
 }

 public Rules() {

 }

 public Rules(int nSnmpTry, int nSnmpVersion, String szCommunity, int nType, int nCurrentTick, String szParam, String szOid, int pollTime, String szUpdateTime, String szCreateTime, String szSnmpIP, int iD, int nSnmpTimeOut, int nSnmpPort) {
  super();
  this.nSnmpTry = nSnmpTry;
  this.nSnmpVersion = nSnmpVersion;
  this.szCommunity = szCommunity;
  this.nType = nType;
  this.nCurrentTick = nCurrentTick;
  this.szParam = szParam;
  this.szOid = szOid;
  this.PollTime = pollTime;
  this.szUpdateTime = szUpdateTime;
  this.szCreateTime = szCreateTime;
  this.szSnmpIP = szSnmpIP;
  this.ID = iD;
  this.nSnmpTimeOut = nSnmpTimeOut;
  this.nSnmpPort = nSnmpPort;
 }

 

调用代码：

JSONArray jsonArray = JSONArray.fromObject(result);
  Map<String, Class> map = new HashMap<String, Class>();
  map.put("rules", Rules.class);
  for (int i = 0; i < jsonArray.size(); i++) {
   JSONObject jsonObject = (JSONObject) jsonArray.get(i);
   ResultRules resultRules = (ResultRules) jsonObject.toBean(jsonObject, ResultRules.class, map);
   System.out.println(resultRules.getUlTaskStatus());
  }

 

 

 

报错情况如下：
