Question

我在jtable排序机制中找不到问题，当我在搜索代码中实现排序时，它给出了数组索引超出范围，填充表代码在初始阶段工作正常但在搜索发生后它是也卡住了。

我的应用程序有一个文本字段区域，它接受用于从数据库中搜索的关键字。现在搜索后，它会在jtable上显示它，我想为它提供表格分类器。任何帮助表示赞赏。 thks。我还提供了下面的堆栈跟踪。

//问题代码

// for searching data from data base and display it in table
// according to the keyword typed.

Answer 1

首先，请不要使用KeyListeners，如果你想要这种行动，请使用ActionListener - 有100个原因，但是现在，只要相信我们;）

尝试在更改模型之前将分拣机设置为null

jTable1.setRowSorter(null);

由于多个线程尝试更新模型不同步而导致突变事件，我经常遇到此问题。

Answer 2

挖掘一下（就像我有时间和事情一样困扰我： - ）

首先：@MadProgrammer的答案是正确的 - 如果客户端代码负责将分类器和模型保持同步，而不是将该负担委托给表。

承担负担的客户代码：

TableModel model = .. //create some model;
table.setModel(model);
table.setRowSorter(new TableRowSorter(model));
// has to remove the rowSorter _before_ setting a new model
// because the old rowSorter still references the old model
table.setRowSorter(null);
TableModel newModel = ... // create some model ;
table.setModel(newModel);
table.setRowSorter(new TableRowSorter(newModel);

让表格照顾：

table.setAutoCreateRowSorter();
TableModel model = .. //create some model;
table.setModel(model);
// nothing to fear, simply set the new
TableModel newModel = ... // create some model ;
table.setModel(newModel);

BTW：在OP的上下文中，没有必要重置模型 - 它基本上是相同的，只是不同的数据。所以

// initially setting the model and rowSorter (in populate)
...
// in re-populating, instead of re-creating the same model 
//table.setModel(newModel);
// clear
((DefaultTableModel) table.getModel()).setRowCount(0);
...
// and - while we are at it - cleanup the logic 
while(result.next()) {
    Object[] rowData = {result.getInt("emp_id"), 
        result.getString("emp_name"), result.getString("emp_address")};
    ((DefaultTableModel) jTable1.getModel()).addRow(rowData);
}

找不到ArrayIndexOutOfBoundsException：6＆gt; 1表示？在排序jtable时
