// 方法一

SwiftParser parser = new SwiftParser(mt940);

SwiftMessage swiftMessage = parser.message();

System.out.println("getSender:" + swiftMessage.getSender());

System.out.println("getReceiver:" + swiftMessage.getReceiver());

System.out.println("getType:" + swiftMessage.getType());

System.out.println("getMtId:" + swiftMessage.getMtId());

System.out.println("getSignature:" + swiftMessage.getSignature());

System.out.println("*******************************************");

SwiftBlock1 swiftBlock1 = swiftMessage.getBlock1();

System.out.println("getApplicationId:" + swiftBlock1.getApplicationId());

System.out.println("getServiceId:" + swiftBlock1.getServiceId());

System.out.println("getLogicalTerminal:" + swiftBlock1.getLogicalTerminal());

System.out.println("getSequenceNumber:" + swiftBlock1.getSequenceNumber());

System.out.println("*******************************************");

SwiftBlock2 swiftBlock2 = swiftMessage.getBlock2();

System.out.println("getBlockValue:" + swiftBlock2.getBlockValue());

System.out.println("*******************************************");

SwiftBlock4 swiftBlock4 = swiftMessage.getBlock4();

Field[] fields = swiftBlock4.getFieldsByName("61");

for (Field field : fields) {

System.out.println("getTagValue:" + field.getValue());

System.out.println("AMOUNT:" + field.getComponent(5));

}

System.out.println("*******************************************");

// 方法二

MT940 mt = MT940.parse(mt940);

for (Field61 tx : mt.getField61()) {

System.out.println("Amount: " + tx.getComponent(Field61.AMOUNT));

System.out.println("Transaction Type: " + tx.getComponent(Field61.TRANSACTION_TYPE));

System.out.println("Reference Acc Owner: " + tx.getComponent(Field61.REFERENCE_FOR_THE_ACCOUNT_OWNER));

}

}

}

运行结果：
