NetBeans IDE 是基于NetBeans Platform搭建的,它的所有功能都是以插件的方式实现的。我们也可以基于NetBeans Platform实现自己的应用,这一点,与Eclipse RCP是等同的。首先,我们先来熟悉一下NetBeans Module的开发 :-)。这个例子是一个用于配置NetBeans启动参数的插件,用它可以使用图形界面配置NetBeans启动参数。当然了,这这是一个例子,Bugs比较多,要使用同种功能的插件,看这里!
准备
点此访问NetBeans下载站点。下载最新的Java基本开发套件就可以了。开始
1. 创建工程
新建工程,选择模块开发:工程命名为CustomStartup,其他的使用默认配置。
2. 编写测试用例
插件随小,无脏俱全哦~ 再说,本着TDD的原则,我们还是先编写一下测试用例吧。测试代码如下:

4. 开始插件咯~
好了,上面贴了很多代码,貌似和NetBeans的插件开发没什么联系。现在我们正式开始介绍插件开发(模块开发)!a. 添加需要的依赖库,也就是Platform的一些APIs:
b.建立Options Panel类型的文件:
c. 打开Panel,设计界面:
d. 主要事件处理代码:
private void confirmJDKHomeBtnActionPerformed(java.awt.event.ActionEvent evt) {
String jdkHomeInput = jdkHomeTextField.getText();
nBConfFile.setNetBeansJDKHome(jdkHomeInput);
}
private void addParasBtnActionPerformed(java.awt.event.ActionEvent evt) {
String newValue = (String) this.argumentsTbl.getCellEditor(
this.argumentsTbl.getEditingRow(), 0).getCellEditorValue();
Vector<String> newRow = new Vector<String>();
newRow.add(newValue);
this.argsTblModel.addRow(newRow);
}
private void removeParasBtnActionPerformed(java.awt.event.ActionEvent evt) {
int selectedRow = this.argumentsTbl.getSelectedRow();
this.argsTblModel.removeRow(selectedRow);
nBConfFile.removeNetBeansDefaultOptions(selectedRow);
}
private void argumentsTblPropertyChange(java.beans.PropertyChangeEvent evt) {
int selectedRow = this.argumentsTbl.getSelectedRow();
if (selectedRow >= 0 && selectedRow <= nBConfFile.getNetBeansDefaultOptions().
size()) {
// edit parameter
String newValue = this.argsTblModel.getValueAt(selectedRow,
0).toString();
nBConfFile.editNetBeansDefaultOptions(selectedRow, newValue);
} else if (selectedRow >= 0 && this.argsTblModel != null &&
this.argsTblModel.getValueAt(selectedRow, 0) != null) {
// add parameter
String newValue = this.argsTblModel.getValueAt(selectedRow,
0).toString();
nBConfFile.addNetBeansDefaultOptions(newValue);
}
}
