优化这段Java代码：if (("S".equals(dept) && "Y".equals(bagInfo.getBagSOpen()) && !"Y".equals(bagInfo.getBagSFinished())) || ("C".equals(dept) && "Y".equals(bagInfo.getBagCOpen()) && !"Y".equals(bagInfo.getBagCFinished())) || ("G".equals(dept) && "Y".equals(bagInfo.getBagGOpen()) && !"Y".equals(bagInfo.getBagGFinished()))) { record.setBagState("0"); record.setBagDescribe("需开包"); } else if (("S".equals(dept) && "Y".equals(bagInfo.getBagSOpen()) && "Y".equals(bagInfo.getBagSFinished())) || ("C".equals(dept) && "Y".equals(bagInfo.getBagCOpen()) && "Y".equals(bagInfo.getBagCFinished())) || ("G".equals(dept) && "Y".equals(bagInfo.getBagGOpen()) && "Y".equals(bagInfo.getBagGFinished()))) { record.setBagState("0"); record.setBagDescribe("开包完成"); } else if ((("S".equals(dept) && "N".equals(bagInfo.getBagSOpen()) && "N".equals(bagInfo.getBagSFinished())) || ("C".equals(dept) && "N".equals(bagInfo.getBagCOpen()) && "N".equals(bagInfo.getBagCFinished())) || ("G".equals(dept) && "N".equals(bagInfo.getBagGOpen()) && "N".equals(bagInfo.getBagGFinished())))) { record.setBagState("0"); record.setBagDescribe("正常"); } else { record.setBagState("0"); record.setBagDescribe("未知"); }

可以将代码中的重复部分提取出来，使用一个方法来判断是否符合条件并设置 record 的值。具体实现如下：

private void setRecordBagState(String dept, BagInfo bagInfo, Record record) {
    if (("Y".equals(getBagOpen(dept, bagInfo)) && !"Y".equals(getBagFinished(dept, bagInfo)))) {
        record.setBagState("0");
        record.setBagDescribe("需开包");
    } else if (("Y".equals(getBagOpen(dept, bagInfo)) && "Y".equals(getBagFinished(dept, bagInfo)))) {
        record.setBagState("0");
        record.setBagDescribe("开包完成");
    } else if (("N".equals(getBagOpen(dept, bagInfo)) && "N".equals(getBagFinished(dept, bagInfo)))) {
        record.setBagState("0");
        record.setBagDescribe("正常");
    } else {
        record.setBagState("0");
        record.setBagDescribe("未知");
    }
}

private String getBagOpen(String dept, BagInfo bagInfo) {
    switch (dept) {
        case "S":
            return bagInfo.getBagSOpen();
        case "C":
            return bagInfo.getBagCOpen();
        case "G":
            return bagInfo.getBagGOpen();
        default:
            return "";
    }
}

private String getBagFinished(String dept, BagInfo bagInfo) {
    switch (dept) {
        case "S":
            return bagInfo.getBagSFinished();
        case "C":
            return bagInfo.getBagCFinished();
        case "G":
            return bagInfo.getBagGFinished();
        default:
            return "";
    }
}

然后在原代码中调用 `setRecordBagState` 方法即可：

setRecordBagState(dept, bagInfo, record);
