嗨我尝试在vaadin中的网格中添加按钮,但它打印按钮对象上的引用.

Grid statementEnquiriesList = new Grid();
statementEnquiriesList.addColumn("", Button.class);
        statementEnquiriesList.addColumn("DATE/TIME", String.class);
        statementEnquiriesList.addColumn("TRANSACTION ID", String.class);
        statementEnquiriesList.addColumn("FROM", String.class);

// historyList is an array object
for (int i = 0; i < historyList.size(); i++)
{
    HistoryList recordObj = historyList.get(i);
    Button addBtn = new Button();
    addBtn.setCaption("Add");
    statementEnquiriesList.addRow(addBtn , recordObj.getDate(), recordObj.getTransactionId(), recordObj.getFrom());
}

我怎样才能在此打印"添加"标题

我试图使用shell脚本运行mv命令,但它给了我

mv: cannot stat `/opt/logs/merchantportal/logger.log.20160501.*': No such file or directory
mv: cannot stat `/opt/logs/merchantapi/logger.log.20160501.*': No such file or directory

//这是我的SHELL SCRIPT

#!/bin/bash
now="$(date +'%Y%m%d')"
merchantPortalLogsPath="/opt/logs/merchantportal"
merchantApiLogsPath="/opt/logs/merchantapi"
currentDate="$(date +%Y%m%d)"
olderDate="$(date "+%Y%m%d" -d "1 days ago")"
merchantPortalLogsPathBackup=$merchantPortalLogsPath"."$olderDate
merchantApiLogsPathBackup=$merchantApiLogsPath"."$olderDate

mkdir $merchantPortalLogsPathBackup
mkdir $merchantApiLogsPathBackup
echo $merchantPortalLogsPath"/logger.log."$olderDate".*" $merchantPortalLogsPathBackup"/"
echo $merchantApiLogsPath"/logger.log."$olderDate".*" $merchantApiLogsPathBackup"/"

mv $merchantPortalLogsPath"/logger.log."$olderDate".*" $merchantPortalLogsPathBackup"/"
mv $merchantApiLogsPath"/logger.log."$olderDate".*" $merchantApiLogsPathBackup"/"

//但是目录是成功创造的

我正在使用 Jboss-fuse-6.3 和外部 Apache-activemq-5.15.2。我在一个队列上绑定了 50 个消费者，在 Active MQ 门户的“活动消费者”页面上，我注意到所有 50 个消费者都已绑定，但队列上的消息分布并不相同。

附上屏幕截图。在会话 ID“1”上，排队消息计数约为 1010 条，但在其他消费者会话上，排队消息仅为 10 条。

我正在对来自 Apache Camel Route 的消息进行排队。下面是我的蓝图 xml（我做错了什么吗）
