开发过程中，经常遇到接口给了xml，需要转化成javabean，字段比较少还好，几十个字段或者更多的话，一个个字段去手打实在太麻烦了，我写了一个小工具来自动生成，省了不少事。

jb4.addActionListener(this);
jpanel.add(jb1);

contentPane.add(jpanel, BorderLayout.SOUTH);
jf.setSize(400, 300);
jf.setLocation(400, 200);
jf.setVisible(true);
jf.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
// 覆盖接口ActionListener的方法actionPerformed
public void actionPerformed(ActionEvent e) {
if (e.getSource() == jb1) {
jta.copy();
} else if (e.getSource() == jb2) {
jta.paste();
} else if (e.getSource() == jb3) {
jta.cut();
} else if (e.getSource() == jb4) {
jta.setText(aotuChange(jta.getText()));
}
}
public String aotuChange(String xml) {
xml = xml.replaceAll("<.*</", "public String ");
xml = xml.replace(">", "; ");
return xml;
}
public static void main(String[] args) {
new Test();
}
}

原理很简单，就是正则表达式替换

| public String aotuChange(String xml) {
xml = xml.replaceAll("<.*</", "public String ");
xml = xml.replaceAll("<(?!\\!)", "public String ");
xml = xml.replaceAll("/>", "; ");
xml = xml.replaceAll("(?<!-)>", "; ");
}

关键代码就这几行。
我把它生成了一个java小工具，可以直接双击运行。
