国农项目weblogic和Tuxedo实现连接
ProtocolHandle--->WtcClient-->WtcConnect
一、WtcConnect:获取Tuxedo的连接：
public class WtcConnect {
static Context ctx;
static TuxedoConnectionFactory tcf;
static {
try {
ctx = new InitialContext();
tcf = (TuxedoConnectionFactory) ctx.
lookup("tuxedo.services.TuxedoConnection");
} catch (NamingException ne) {
try {
throw new WtcException(TPException.TPENOENT,
"Could not get the tuxedo object: " + ne);
} catch (WtcException e) {
e.printStackTrace();
}
}
}
public static TuxedoConnection getConnection() {
TuxedoConnection conn = null;
try {
conn = tcf.getTuxedoConnection();
} catch (TPException e) {
e.printStackTrace();
}
return conn;
}
}
二、WtcClient类：
FldMessage---》fml32SetValue()---》TypedFML32---》tpCallFML32()----》TypedFML32----》fml32GetValue()---》FldMessage
1、FldMessage：
public class FldMessage {
private Integer ver;
private String reqsys;
private String reqnode;
private String txcode;
private Integer reqno;
private String encode;
private String dynauth;
private Integer mac;
private String data;
private String rspsys;
private String rspnode;
private Integer rspno;
private Integer rspstat;
}
2、tpCallFML32()
public boolean tpCallFML32() throws TPException, TPReplyException, Ferror {
TuxedoConnection tuxConn;
Reply tuxReply;
XmlFmlCnv c = new XmlFmlCnv();
if (fml32SetValue() == false) {
return false;
}
tuxConn = WtcConnect.getConnection();//获取连接
try {
tuxReply = tuxConn.tpcall(this.service, sndFmlBuffer, 0);//调用服务
rcvFmlBuffer = (TypedFML32) tuxReply.getReplyBuffer();//获取返回数据
tuxConn.tpterm();//关闭连接
} catch (TPReplyException tre) {
logger.error("tpcall threw TPReplyExcption " + tre);
throw tre;
} catch (TPException te) {
logger.error("tpcall threw TPException " + te);
throw te;
} catch (Exception ee) {
logger.error("tpcall threw exception: " + ee);
throw new TPException(TPException.TPESYSTEM, "Exception: " + ee);
} finally {
tuxConn.tpterm();
}
if (rcvFmlBuffer == null) {
logger.error("响应数据报文为空");
return false;
}
if (fml32GetValue() == false) {
return false;
}
return true;
}
3、fml32SetValue()【 FldMessage---》fml32SetValue()---》TypedFML32】
sndFmlBuffer.Fchg(sndFmlBuffer.Fldid("PHF_VER"), 0, sndFldMsg.getVer());//调用的是：TypedFML32.Fchg(TypedFML32.Fldid("字段名称"), 0, "字段值");
4、fml32GetValue()【TypedFML32----》FldMessage】
Object obj = null;
rcvFldMsg = new FldMessage();
TypedFML32 fml32 = new TypedFML32(new CnacexFld());
if (fldExist(rcvFmlBuffer, fml32.Fldid("PHF_VER"))) {
obj = rcvFmlBuffer.Fget(fml32.Fldid("PHF_VER"), 0);//从TypedFML32中获取字段值
if (obj != null)
rcvFldMsg.setVer(Integer.parseInt(obj.toString().trim()));
}
}
5、fldExist(TypedFML32 fml32, int filId)
private boolean fldExist(TypedFML32 fml32, int filId) {
try {
fml32.Fget(filId, 0);
} catch (Ferror e) {
if (e.getFerror() == e.FNOTPRES) {
return false;
}
return true;
}
return true;
}
三、ProtocolHandle类：
public class ProtocolHandle {
private int requestNo;
private ConfigData config = ConfigData.getInstance();
/**
* 底层数据交换
*/
public PackageModul handle(ProtocolCode code, PackageModul modul) {
int reqNo = 0;
synchronized (this) {
if (requestNo++ > 1000000)
requestNo = 0;
reqNo = requestNo;
}
WtcClient wtcClient = new WtcClient();
// 组装包内容
CRC32 crc32 = new CRC32();
FldMessage request = new FldMessage();
request.setVer(config.getProtocolVersion());
request.setReqsys(config.getReqSysNo());
request.setTxcode(code.getKey());
request.setReqno(reqNo & 0x7FFFFFFF);
// 组装body内容
String nameSpace = getRandomString(1);
String context = XmlUtil.toXml(modul,nameSpace);
int index = context.lastIndexOf("</"+nameSpace+":root>");
context = context.substring(0, index) + modul.getBody() + context.substring(index);
//设置crc32校验码
try {
crc32.update(context.getBytes("utf-8"));
} catch (UnsupportedEncodingException e1) {
e1.printStackTrace();
}
request.setMac((int) crc32.getValue() & 0x7FFFFFFF);
//设置传送数据
request.setData(context);
//设置要请求的服务
wtcClient.setService(code.getService());
wtcClient.setSndFldMsg(request);
try {
wtcClient.tpCallFML32();
} catch (TPReplyException e) {
throw new ProtocolException(this, reqNo, e);
} catch (TPException e) {
throw new ProtocolException(this, reqNo, e);
} catch (Ferror e) {
throw new ProtocolException(this, reqNo, e);
}
FldMessage response = wtcClient.getRcvFldMsg();
if (response == null)
throw new ProtocolException(this, reqNo, new NullPointerException());
String data = response.getData();//获取tuxedo返回的数据
response.getReqno(), data);
crc32.update(data.getBytes());
PackageModul result = XmlUtil.fromXml(data, PackageModul.class);
if (response.getRspstat() == 0) {
// 分解BODY内容
int start = data.indexOf(Constants.BODY_START);
int end = data.lastIndexOf(Constants.BODY_END)
+ Constants.BODY_END.length();
String body = null;
if (start >= 0 && end >= 0) {
body = data.substring(start, end);
data = data.substring(0, start) + data.substring(end);
}
result.setBody(body);
result.setFault(null);
}
result.setReqNo(reqNo);
return result;
}
private String getRandomString(int length) { //length表示生成字符串的长度
String base = "abcdefghijklmnopqrstuvwxyz";
Random random = new Random();
StringBuffer sb = new StringBuffer();
for (int i = 0; i < length; i++) {
int number = random.nextInt(base.length());
sb.append(base.charAt(number));
}
return sb.toString();
}
}
