问题是这样的:
在第一次点击添加按钮
弹出子窗口时,数据都是正常录入的
并且能添加到主窗口的表格和数据库中但是关闭这个子窗口
再重新打开
就出现了问题了,这次数据自己录入了两次,就是我输入的值录入一次,然后程序自己自个又录入一次当我再次关闭这个子窗口,又重新打开
这次我输入一次,程序多重复录入两次!!!程序自己重复录入的次数和我关闭再打开的次数有关!!!如果第一次打开,我输入一次,点击确认按钮一次,程序总是正常的,应该不是监听器释放的问题,而关闭一个窗口,应该是将其所有资源都释放了为什么和和子窗口的打开关闭次数有关???
代码如下:

这些插件 在每次点击增加用户的时候都是新的重新new的
但是

JLabel passwordLabel =new JLabel("密码:");

JLabel userRightSetLabel=new JLabel("权限:");
至始至终就一个
虽然你每次点击增加新用户时都重新new 了button
但是每次new的和上次关闭的的button是一样的 我输出来看过了 坐标之类的都一样
javax.swing.JButton[,120,0,60x26,alignmentX=0.0,alignmentY=0.5,border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@3ee284,flags=296,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,disabledSelectedIcon=,margin=javax.swing.plaf.InsetsUIResourc[top=2,left=14,bottom=2,right=14],paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=true,rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=确认,defaultCapable=true]
add_User_Window.dispose();并没有销毁窗口只是影藏了
这样就很明显了 你点击了那个按钮 其实点击了两个按钮先前的那一个一起点了 而且你每次触发新增用户都会给按钮重新添加yesButton.addActionListener(new ActionListener() 动作监听,当然是执行两次按钮事件 依次类推三次 四次
