我试图阅读谷歌邮件(Gmail-imaps)账户中的所有邮件并下载其附件,但我只能收到一封未读邮件及其附件

发布我的代码片段

// Download function 

public void  download() throws Exception {

        PollingConsumer pollingConsumer = null;
        CamelContext context = new DefaultCamelContext();

        Endpoint endpoint =
                context.getEndpoint("imaps://imap.gmail.com?username="
                        + mailId + "&password=" + password 
                        + "&delete=false&peek=false&unseen=true&consumer.delay=60000&closeFolder=false&disconnect=false");

        pollingConsumer = endpoint.createPollingConsumer();
        pollingConsumer.start();

        pollingConsumer.getEndpoint().createExchange();
        Exchange exchange = pollingConsumer.receive();

        log.info("exchange : " + exchange.getExchangeId());
        process(exchange);

}

// mail process function

public void process(Exchange exchange) throws Exception {
    Map<String, DataHandler> attachments = exchange.getIn().getAttachments();

    Message messageCopy = exchange.getIn().copy();

    if (messageCopy.getAttachments().size() > 0) {
        for (Map.Entry<String, DataHandler> entry : messageCopy.getAttachments().entrySet()) {
            DataHandler dHandler = entry.getValue();
            // get the file name
            String filename = dHandler.getName();

            // get the content and convert it to byte[]
            byte[] data =
                    exchange.getContext().getTypeConverter().convertTo(byte[].class, dHandler.getInputStream());

            FileOutputStream out = new FileOutputStream(filename);
            out.write(data);
            out.flush();
            out.close();
            log.info("Downloaded attachment, file name : " + filename);

        }
    }
}
//下载功能
public void download()引发异常{
PollingConsumer PollingConsumer=null;
CamelContext=新的DefaultCamelContext();
端点=
context.getEndpoint(“imaps://imap.gmail.com?username="
+mailId+“&password=“+password”
+“&delete=false&peek=false&unseen=true&consumer.delay=60000&closeFolder=false&disconnect=false”);
pollingConsumer=endpoint.createPollingConsumer();
pollingConsumer.start();
pollingConsumer.getEndpoint().createExchange();
Exchange=pollingConsumer.receive();
log.info(“exchange:+exchange.getExchangeId());
过程(交换);
}
//邮件处理功能
公共作废进程(Exchange)引发异常{
映射附件=exchange.getIn().getAttachments();
messageCopy=exchange.getIn().copy();
如果(messageCopy.getAttachments().size()>0){
对于(Map.Entry:messageCopy.getAttachments().entrySet()){
DataHandler dHandler=entry.getValue();
//获取文件名
字符串文件名=dHandler.getName();
//获取内容并将其转换为字节[]
字节[]数据=
exchange.getContext().getTypeConverter().convertTo(字节[].class,dHandler.getInputStream());
FileOutputStream out=新的FileOutputStream(文件名);
输出。写入(数据);
out.flush();
out.close();
log.info(“下载的附件,文件名:”+文件名);
}
}
}

帮助我遍历所有邮件(来自收件箱,未读)。

您需要运行
Exchange=pollingConsumer.receive()在循环中

例如

Exchange ex = pollingConsumer.receive();
while (ex != null) {
    process(ex);
    ex = pollingConsumer.receive();
}

但我的问题是,我如何反复浏览我的邮件。现在我收到1封未读邮件,但我需要所有来自inboxI的未读邮件。对不起。我根据题目误读了你的问题。编辑修复的答案。
