生成代码：完成一个Java文本编辑器，要求实现基本的文本文件读取、自动保存、保存、设置字号颜色、查找等功能，实现剪切板操作，有菜单栏、工具栏和状态栏。

很高兴听到您的需求。下面是一个简单的Java文本编辑器的代码，它实现了您提到的大部分功能。您可以在此基础上进行修改和扩展。

代码中使用了Swing库来构建图形界面，其中JTextArea用于显示文本内容，JFileChooser用于选择文件，JMenuBar、JMenu、JMenuItem用于创建菜单，JToolBar用于创建工具栏，JLabel用于显示状态信息，JOptionPane用于显示确认对话框等。另外，我们还使用了一些Java API来实现文件读写、剪切板操作等功能。

您可以将代码保存为TextEditor.java，并在命令行中编译运行它，或使用Eclipse、IntelliJ IDEA等集成开发环境来运行它。
