在java中，有个List<PassengerDetailInfoPhoneNbr> phoneList的集合，数据为[{ "passengerPhoneNbr": "13614383602", "ecifPhoneNbr": "", "agentPhoneNbr": "13614380243", "customPhoneNbr": "", "chnName": "张忠", "oldFltDt": "2023-05-31 08:00:00", "oldDptAirportCd": "DSN", "oldArvAirportCd": "CGQ", "oldFltNbr": "KN2359", "newFltDt": "2023-06-01 08:00:00", "newDptAirportCd": "DSN", "newArvAirportCd": "CGQ", "newFltNbr": "KN2359" }]，现在根据passengerPhoneNbr，ecifPhoneNbr，agentPhoneNbr，customPhoneNbr,去重新生成数据，最后的格式为[{ "phoneEncryption": "13614383602", "chnName": "张忠", "oldFltDt": "2023-05-31 08:00:00", "oldDptAirportCd": "DSN", "oldArvAirportCd": "CGQ", "oldFltNbr": "KN2359", "newFltDt": "2023-06-01 08:00:00", "newDptAirportCd": "DSN", "newArvAirportCd": "CGQ", "newFltNbr": "KN2359" }, { "phoneEncryption": "", "chnName": "张忠", "oldFltDt": "2023-05-31 08:00:00", "oldDptAirportCd": "DSN", "oldArvAirportCd": "CGQ", "oldFltNbr": "KN2359", "newFltDt": "2023-06-01 08:00:00", "newDptAirportCd": "DSN", "newArvAirportCd": "CGQ", "newFltNbr": "KN2359" }, { "phoneEncryption": "13614380243", "chnName": "张忠", "oldFltDt": "2023-05-31 08:00:00", "oldDptAirportCd": "DSN", "oldArvAirportCd": "CGQ", "oldFltNbr": "KN2359", "newFltDt": "2023-06-01 08:00:00", "newDptAirportCd": "DSN", "newArvAirportCd": "CGQ", "newFltNbr": "KN2359" }, { "phoneEncryption": "", "chnName": "张忠", "oldFltDt": "2023-05-31 08:00:00", "oldDptAirportCd": "DSN", "oldArvAirportCd": "CGQ", "oldFltNbr": "KN2359", "newFltDt": "2023-06-01 08:00:00", "newDptAirportCd": "DSN", "newArvAirportCd": "CGQ", "newFltNbr": "KN2359" } ]

你可以使用Java 8的Stream API和lambda表达式来实现该操作。首先，你需要创建一个新的PassengerDetailInfoPhoneNbr对象的列表。然后，使用forEach()方法对原始列表中的每个元素进行遍历，根据每个元素的passengerPhoneNbr、ecifPhoneNbr、agentPhoneNbr、customPhoneNbr属性的值来创建新的PassengerDetailInfoPhoneNbr对象，并将其添加到新的列表中。最后，将新列表作为结果返回即可。以下是代码示例：

List<PassengerDetailInfoPhoneNbr> phoneList = ... // 从某个地方获取PassengerDetailInfoPhoneNbr对象列表
List<PassengerDetailInfoPhoneNbr> newPhoneList = new ArrayList<>();

phoneList.forEach(phone -> {
    // 根据passengerPhoneNbr、ecifPhoneNbr、agentPhoneNbr、customPhoneNbr属性的值创建新的PassengerDetailInfoPhoneNbr对象
    PassengerDetailInfoPhoneNbr newPhone1 = new PassengerDetailInfoPhoneNbr();
    newPhone1.setPhoneEncryption(phone.getPassengerPhoneNbr());
    newPhone1.setChnName(phone.getChnName());
    newPhone1.setOldFltDt(phone.getOldFltDt());
    newPhone1.setOldDptAirportCd(phone.getOldDptAirportCd());
    newPhone1.setOldArvAirportCd(phone.getOldArvAirportCd());
    newPhone1.setOldFltNbr(phone.getOldFltNbr());
    newPhone1.setNewFltDt(phone.getNewFltDt());
    newPhone1.setNewDptAirportCd(phone.getNewDptAirportCd());
    newPhone1.setNewArvAirportCd(phone.getNewArvAirportCd());
    newPhone1.setNewFltNbr(phone.getNewFltNbr());
    newPhoneList.add(newPhone1);

    PassengerDetailInfoPhoneNbr newPhone2 = new PassengerDetailInfoPhoneNbr();
    newPhone2.setPhoneEncryption(phone.getEcifPhoneNbr());
    newPhone2.setChnName(phone.getChnName());
    newPhone2.setOldFltDt(phone.getOldFltDt());
    newPhone2.setOldDptAirportCd(phone.getOldDptAirportCd());
    newPhone2.setOldArvAirportCd(phone.getOldArvAirportCd());
    newPhone2.setOldFltNbr(phone.getOldFltNbr());
    newPhone2.setNewFltDt(phone.getNewFltDt());
    newPhone2.setNewDptAirportCd(phone.getNewDptAirportCd());
    newPhone2.setNewArvAirportCd(phone.getNewArvAirportCd());
    newPhone2.setNewFltNbr(phone.getNewFltNbr());
    newPhoneList.add(newPhone2);

    PassengerDetailInfoPhoneNbr newPhone3 = new PassengerDetailInfoPhoneNbr();
    newPhone3.setPhoneEncryption(phone.getAgentPhoneNbr());
    newPhone3.setChnName(phone.getChnName());
    newPhone3.setOldFltDt(phone.getOldFltDt());
    newPhone3.setOldDptAirportCd(phone.getOldDptAirportCd());
    newPhone3.setOldArvAirportCd(phone.getOldArvAirportCd());
    newPhone3.setOldFltNbr(phone.getOldFltNbr());
    newPhone3.setNewFltDt(phone.getNewFltDt());
    newPhone3.setNewDptAirportCd(phone.getNewDptAirportCd());
    newPhone3.setNewArvAirportCd(phone.getNewArvAirportCd());
    newPhone3.setNewFltNbr(phone.getNewFltNbr());
    newPhoneList.add(newPhone3);

    PassengerDetailInfoPhoneNbr newPhone4 = new PassengerDetailInfoPhoneNbr();
    newPhone4.setPhoneEncryption(phone.getCustomPhoneNbr());
    newPhone4.setChnName(phone.getChnName());
    newPhone4.setOldFltDt(phone.getOldFltDt());
    newPhone4.setOldDptAirportCd(phone.getOldDptAirportCd());
    newPhone4.setOldArvAirportCd(phone.getOldArvAirportCd());
    newPhone4.setOldFltNbr(phone.getOldFltNbr());
    newPhone4.setNewFltDt(phone.getNewFltDt());
    newPhone4.setNewDptAirportCd(phone.getNewDptAirportCd());
    newPhone4.setNewArvAirportCd(phone.getNewArvAirportCd());
    newPhone4.setNewFltNbr(phone.getNewFltNbr());
    newPhoneList.add(newPhone4);
});

// 返回新的PassengerDetailInfoPhoneNbr对象列表
return newPhoneList;
