篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了MML华为MML AAA接口联调，Java版本相关的知识，希望对你有一定的参考价值。
1、我们先设置一些常量数据
package cn.cutter.ztesoft.HuWeiMML.constrant; /** * @description: AAA接口常量设置 * @author: xiaof * @create: 2018-07-26 10:07 **/ public class InfAAAMissionConstrant { /** *订单号，工单号，宽带账号 */ public static final String AAA_ORDER_ID = "orderId"; public static final String AAA_WORK_ORDER_ID = "workOrderId"; public static final String AAA_ACCOUNT = "accNbr"; public static final String USER_MOBILE = "mobile"; /** * 配置信息 */ // public static final String IOM_IP; public static final String AAA_IP = "IP"; public static final String AAA_PORT = "PORT"; public static final String AAA_USER_NAME = "USERNAME"; public static final String AAA_PASS_WORD = "PASSWORD"; public static final String AAA_CONFIG_TYPE = "AAA_SOCKET_INFO"; public static final String SERVICEFLAG = "AAA"; //消息头 AAA_MSG_STARTING_INT x1Cx1Dx1Ex1F public static final String AAA_MSG_STARTING = "`SC`"; public static final int AAA_MSG_STARTING_INT = 0x1C1D1E1F; public static final byte[] AAA_MSG_STARTING_BYTE = {0x1C, 0x1D, 0x1E, 0x1F}; /** * AAA IIN类型格式发送字节消息 0x60, 0x53, 0x43, 0x60 */ public static final byte[] AAA_IIN_MSG_STARTING_BYTE = {0x60, 0x53, 0x43, 0x60}; public static final int AAA_MSG_STARTTAG_LEN = 4; //消息开始标识长度 public static final int AAA_MSG_COMM_LEN = 12; /** * 消息头长度 */ public static final int AAA_MSG_HEAD_LEN = 20; /** * 消息长度部位 */ public static final int AAA_MSG_INFO_LEN = 4; //消息版本号 public static final String AAA_MSG_VERSION = "1.00"; public static final Integer AAA_MSG_VERSION_LEN = 4; public static final int AAA_MSG_STARTING_LEN = 4; /** * 终端标识 */ public static final String AAA_MSG_TERMINAL = "internal"; public static final Integer AAA_MSG_TERMINAL_LEN = 8; public static final Integer AAA_SERVICE_CODE_LEN = 8; public static final Integer AAA_MAX_HEAD_LEN = 56; // 会话控制字包括：DLGLGN，DLGBEG，DLGCON，DLGEND。 // 说明 // 操作员登录MML Server时客户端发DLGLGN，在进行其他操作时，客户端均发DLGCON。 // 操作员退出时，MMLServer给营帐的返回消息中会话控制字为DLGEND，表示会话的结束。 /** * 会话id长度 */ public static final int AAA_DLG_ID_LEN = 8; public static final String AAA_DLG_LGN = "DLGLGN"; public static final String AAA_DLG_BEG = "DLGBEG"; public static final String AAA_DLG_CON = "DLGCON"; public static final String AAA_DLG_END = "DLGEND"; /** * 会话控制字长度 */ public static final int AAA_DLG_CONTROLLER_LEN = 6; /** * 会话保留字 */ public static final int AAA_DLG_RSVD_LEN_DLGRSVD = 4; /** * 会话头长度 */ public static final int AAA_DLG_HEAD_LEN = 18; // 事务控制字包括：TXBEG，TXCON，TXEND。 // 说明 // 由Provision发起的操作，其事务控制字填写TXBEG。 // 当一条MML命令的消息结束时，MML Server返回给Provision的事务控制字为TXEND，表示一条事务结束。 /** * 事务id长度 */ public static final int AAA_TX_ID_LEN = 8; public static final String AAA_TX_BEG = "TXBEG"; public static final String AAA_TX_CON = "TXCON"; public static final String AAA_TX_END = "TXEND"; public static final Integer AAA_TX_CONTROLLER_LEN = 6; /** * 事务保留字长度 */ public static final int AAA_TX_RSVD_LEN_DLGRSVD = 4; /** * 事务头长度 */ public static final int AAA_TX_HEAD_LEN = 18; /** * 校验和长度 */ public static final Integer AAA_CHK_LEN = 4; /** * IIN校验和长度 */ public static final Integer AAA_IIN_CHK_LEN = 8; /** * 报文字段 */ /** * 返回值。十进制整数类型。 * 0表示执行成功，其他返回值的解释请参见DESC字段 */ public static final String RETN = "RETN"; /** * 查询属性名列表，以“&”分隔。 */ public static final String ATTR = "ATTR"; /** * 返回的记录的值，用&分割结果。s */ public static final String RESULT = "RESULT"; }
2、创建对应的信息vo载体
package cn.cutter.ztesoft.HuWeiMML.vo; /** * @program: * @description: * @author: xiaof * @create: 2018-07-26 15:25 **/ public class MsgInfo { /** * 消息和消息长度 */ private byte msg[]; private int msgLen; // 查询用户信息获取 用户IP地址 USERIPADDRESS，USERPORT 用户端口号，业务标识SERVICEFLAG 默认AAA private String userIpAddress; private String userPort; private String serviceFlag; //AAA服务类型,默认C280 private String serviceCode = "C280"; //AAA用来做指令标识 private String workOrderId; private String userName; private String passWord; public byte[] getMsg() { return msg; } public void setMsg(byte[] msg) { this.msg = msg; } public int getMsgLen() { return msgLen; } public void setMsgLen(int msgLen) { this.msgLen = msgLen; } public String getUserIpAddress() { return userIpAddress; } public void setUserIpAddress(String userIpAddress) { this.userIpAddress = userIpAddress; } public String getUserPort() { return userPort; } public void setUserPort(String userPort) { this.userPort = userPort; } public String getServiceFlag() { return serviceFlag; } public void setServiceFlag(String serviceFlag) { this.serviceFlag = serviceFlag; } public String getServiceCode() { return serviceCode; } public void setServiceCode(String serviceCode) { this.serviceCode = serviceCode; } public String getWorkOrderId() { return workOrderId; } public void setWorkOrderId(String workOrderId) { this.workOrderId = workOrderId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getPassWord() { return passWord; } public void setPassWord(String passWord) { this.passWord = passWord; } }
3、创建编码解码器，进行报文的编码解码（关键，划重点哦，特别是校验和的计算）
package cn.cutter.ztesoft.HuWeiMML.Template; import cn.cutter.ztesoft.HuWeiMML.vo.MsgInfo; import java.io.IOException; /** * @program: * @description: MML消息解码，编码器 * @author: xiaof * @create: 2018-08-15 11:38 **/ public interface MsgCoder { /** * 指令编码 * @param msg * @return * @throws IOException */ byte[] toWire(MsgInfo msg) throws IOException; /** * 指令解码 * @param input * @return * @throws IOException */ byte[] fromWire(byte input[]) throws IOException; }
package cn.cutter.ztesoft.HuWeiMML.Template; import cn.cutter.ztesoft.HuWeiMML.constrant.InfAAAMissionConstrant; import cn.cutter.ztesoft.HuWeiMML.vo.MsgInfo; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import java.util.Arrays; /** * * * 1 1 1 1 1 1 * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | 0x60, 0x53, 0x43, 0x60 | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | msg length 4B | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | | * | msg head 20B | * | | * | | * | | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | | * | Conversation head (18B) | * | | * | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | | | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | * | | * | transaction head (18) | * | | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | | * ~ operator msg(N * 4B) ~ * | | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * | | * | check(8B) | * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * * @program: * @description: MML指令编码解析 * @author: xiaof * @create: 2018-08-15 11:40 **/ public class MMLMsgBinCoder implements MsgCoder { private static final Log logger = LogFactory.getLog(MMLMsgBinCoder.class);

4、创建对应的成帧器，来获取发送每一帧信息
package cn.cutter.ztesoft.HuWeiMML.Template; import java.io.IOException; import java.io.OutputStream; /** * @program: * @description: 成帧器 * @author: xiaof * @create: 2018-08-15 10:34 **/ public interface Framer { /** * 添加成帧信息并将制定消息输出到制定流 * @param message * @param out * @throws IOException */ void frameMsg(byte message[], OutputStream out) throws IOException; /** * 扫描指定的流，抽取下一条消息 * @return * @throws IOException */ byte[] nextMsg() throws IOException; }
package cn.cutter.ztesoft.HuWeiMML.Template; import cn.cutter.ztesoft.HuWeiMML.constrant.InfAAAMissionConstrant; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import java.io.DataInputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.util.Arrays; /** * @program: * @description: MML成帧器 * @author: xiaof * @create: 2018-08-15 10:35 **/ public class MMLFramer implements Framer { private static final Log logger = LogFactory.getLog(MMLFramer.class); private static final int MAX_MESSAGE_LENGTH = 65535; private static final int BYTE_MASK = 0xff; private static final int SHORT_MASK = 0xffff; private static final int BYTE_SHIFT = 8; private DataInputStream in; public MMLFramer(InputStream in) { this.in = new DataInputStream(in); } @Override public void frameMsg(byte[] message, OutputStream out) throws IOException { //1.判断消息是否超长了 if(message.length > MAX_MESSAGE_LENGTH) { throw new IOException("消息超长了"); } //输出消息 out.write(message); out.flush(); } @Override public byte[] nextMsg() throws IOException { boolean isMsg = false; int length = 0; try { //1.读取2个字节，用来获取信息长度信息 byte beginMark[] = new byte[4]; byte msgLength[] = new byte[4]; in.read(beginMark); //判断是否，IIN开始标识 if(Arrays.equals(beginMark, InfAAAMissionConstrant.AAA_IIN_MSG_STARTING_BYTE)) { isMsg = true; } else { return new byte[0]; } //读取消息长度 从消息头到操作信息结束（包括填充的空格）的长度，16进制字符(0-F)表示的16位整数(4B)，取值范围为56到65000(10进制) in.read(msgLength); length = tranByteToInt(msgLength); } catch (IOException e) { // e.printStackTrace(); //输出报错信息 logger.error(e.getMessage(), e); return null; } //2.创建相应长度的字节数组 byte msg[] = new byte[length + InfAAAMissionConstrant.AAA_IIN_CHK_LEN]; //3.读取相应数据长度字节进入数组 in.readFully(msg); //这个方法会不断读取数据，直到数组填满，否则阻塞 return msg; } /** * 转换消息长度 * @return */ private int tranByteToInt(byte byteMsgLength[]) { //获取数据16进制 String hexStr = new String(byteMsgLength); int result = Integer.parseInt(hexStr, 16); return result; } }
5、根据模板模式，设计模板类，用来与MML服务器通信
package cn.cutter.ztesoft.HuWeiMML.Template; import java.io.InputStream; import java.io.OutputStream; /** * @program: * @description: MML操作接口 * @author: xiaof * @create: 2018-08-15 15:17 **/ public interface MMLOperatorInvoke { void doCammand(InputStream in, OutputStream os); }
package cn.cutter.ztesoft.HuWeiMML.Template; import cn.cutter.ztesoft.HuWeiMML.vo.MsgInfo; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import java.io.*; import java.net.Socket; /** * @program: 湖北移动智慧装维支撑系统 * @description: 华为MML指令IIN类型 * @author: xiaof * @create: 2018-08-15 10:29 **/ public class AAAMMLIINTemplate { private static final Log logger = LogFactory.getLog(AAAMMLIINTemplate.class); private static final String MML_LOGOUT = "logout:"; private static final String MML_LOGIN_COMMAND = "LOGIN:USER={1},PSWD={2}"; public static void sendMML(String ip, int port, MsgInfo msgInfo, MMLOperatorInvoke mmlOperatorInvoke) { //1.声明相应输入输出对象变量 InputStream is = null; OutputStream os = null; BufferedReader br = null; try { //2.创建socket对象 Socket socket = new Socket(ip, port); socket.setSoTimeout(10 * 1000); //10s超时 //3.建立相应输入输出流 is = socket.getInputStream(); br = new BufferedReader(new InputStreamReader(is)); os = socket.getOutputStream(); //先发送登陆指令 MsgCoder msgCoder = new MMLMsgBinCoder(); String loginMsgCommand = MML_LOGIN_COMMAND.replace("{1}", msgInfo.getUserName()) .replace("{2}", msgInfo.getPassWord()); msgInfo.setMsg(loginMsgCommand.getBytes()); msgInfo.setMsgLen(loginMsgCommand.length()); msgInfo.setServiceCode("C280"); byte loginMsg[] = msgCoder.toWire(msgInfo); int loginTimes = 0; boolean isOk = false; os.write(loginMsg); os.flush(); byte buf[] = new byte[65500]; logger.info("发送AAA登陆信息：" + new String(loginMsg)); while(loginTimes < 3 && !isOk) { is.read(buf); logger.info(new String(buf)); ++loginTimes; if(buf.length > 0) isOk = true; } if(isOk) mmlOperatorInvoke.doCammand(is, os); } catch (Exception e) { logger.error(e.getMessage(), e); } finally { try { //退出登陆logut MsgCoder msgCoder = new MMLMsgBinCoder(); msgInfo.setMsg(MML_LOGOUT.getBytes()); msgInfo.setMsgLen(MML_LOGOUT.length()); byte logoutMsg[] = msgCoder.toWire(msgInfo); logger.info("发送AAA登出信息：" + new String(logoutMsg)); os.write(logoutMsg); os.flush(); if(br != null) { br.close(); } if(is != null) { is.close(); } if(os != null) { os.close(); } } catch (IOException e) { logger.error(e.getMessage(), e); } } } public static void sendMMLHeartBeat(String ip, int port, MsgInfo msgInfo, MMLOperatorInvoke mmlOperatorInvoke) { //1.声明相应输入输出对象变量 InputStream is = null; OutputStream os = null; BufferedReader br = null; try { //2.创建socket对象 Socket socket = new Socket(ip, port); socket.setSoTimeout(10 * 1000); //10s超时 //3.建立相应输入输出流 is = socket.getInputStream(); br = new BufferedReader(new InputStreamReader(is)); os = socket.getOutputStream(); //先发送登陆指令 mmlOperatorInvoke.doCammand(is, os); } catch (Exception e) { logger.error(e.getMessage(), e); } finally { try { //退出登陆logut if(br != null) { br.close(); } if(is != null) { is.close(); } if(os != null) { os.close(); } } catch (IOException e) { logger.error(e.getMessage(), e); } } } }
6、发送指令操作
直接调用（各个地方的某些字段可能不同，这个参考常量文件设置，还有部分参数在msginfo中设置，其余部分基本不需要修改，直接使用）
AAAMMLIINTemplate.sendMML 方法即可
最后想说一句，这个接口是真的不友好，特别是跟我联调的那哥们都不了解他们自己的服务器，接口文档也不详细，问啥都是不知道，哎，真的是伤，
脑壳疼，希望这里能帮助广大没办法只能调华为的这个鬼MML接口的同行们了。。。
