当我创建我的类时，注释位用于调试，这个类在一段时间内没有改变，因此它们不再是必需的。
编辑：sendToServer()就在那里，所以每次我向流写一些内容时，我都不必输入flush()和reset()：
static void sendToServer(Object obj) throws IOException {
out.writeObject(obj);
out.flush();
out.reset();
}
其中out是在连接时与服务器建立的ObjectOutputStream。
编辑2：这是我将SQLTableModel的实例发送到服务器的地方：
ConnectionPane.sendToServer("add");
ConnectionPane.sendToServer(lblTableName.getText());
ConnectionPane.sendToServer(addTable.getModel());
String response = (String) ConnectionPane.in.readObject();
if (response.equals("done")) {
closeFrame();
}
这是在服务器端接收它的位：
else if (cmd.equals("add")) {
String tableName = (String) client.in.readObject();
String exec = "add " + tableName + " (";
SQLTableModel data = (SQLTableModel) client.in.readObject(); //this is where the exception is thrown
...
addTable是一个空表，其中包含用户填写信息的列名。完成后，他们点击添加，然后发送该表模型。
答案 0 :(得分：3)
在projectclient.ConnectionPane.sendToServer(ConnectionPane.java:131)，您调用某个对象的序列化，最终导致EventListenerList的序列化。该对象的代码试图传递序列化java.lang.reflect.Constructor以及那些失败的内容。但是，这是根本原因，而反序列化时，近因是一个例外。序列化已中止但有例外，但显然您没有在 write 侧检测到它，并且您看到异常转移到读取端。
正如您在编辑中解释的那样，sendToServer将其参数序列化。然后问题在于projectclient.AddRecordFrame.btnAddRecordActionPerformed(AddRecordFrame.java:144)，它决定了要发送给服务器的对象。
如果您确实尝试序列化整个SQLTableModel，那么这显然是一种误导的方法，因为它是一个Swing GUI类并包含大量的簿记代码 - 其中包括{{1}在你的情况下失败了。您可能只想传输表格内容，这是您控制的集合 - EventListenerList。仅将该集合发送到服务器。
答案 1 :(得分：2)
只需查看堆栈跟踪，这一行告诉我们：
at javax.swing.event.EventListenerList.writeObject(EventListenerList.java:257)
换句话说，AbstractTableModel会保留一个任意事件侦听器对象的列表，这些对象可以是任何类，Serializable或不是AbstractTableModel，当Serializable被序列化时，尝试用于序列化这些事件侦听器。当听众自己不是data时，这将失败。这可以解释为什么它是一个短暂的问题，因为事件监听器可以随着程序的运行而来来去去。
但是肯定还有其他问题：特别是，您没有做出任何特殊安排来序列化Serializable数组的内容，并且它所包含的对象不能保证{{1自己。
