将原来的程序：
            ZipEntry entry = new ZipEntry( "file3.txt" );
            zos.putNextEntry( entry );
            workbook.write( zos );
            zos.closeEntry();
改为：
            ZipEntry entry = new ZipEntry( "file3.txt" );
            zos.putNextEntry( entry );
            workbook.write( new NonCloseableOutputStream( zos ) );
            zos.closeEntry();

其中 NonCloseableOutputStream 定义如下：
public class NonCloseableOutputStream extends java.io.FilterOutputStream {
    public NonCloseableOutputStream(OutputStream out) {
        super(out);
    }
    @Override public void close() throws IOException {
        flush();
    }
}



2. 使用binary使得mysql区分大小写
select * from table1 where binary field1 = 'abc';

logger.debug( "array: {}", (Object) splits );

这里要注意的就是要把数组的数据类型强制转换为Object

1、先停止mysql数据库

2、保存密码重置sql文件
     5.7.6（包括）以后的版本：ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
     5.7.5（包括）以前的版本：SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');
假设保存到文件: c:\reset.txt

3、以管理员身份打开命令行窗口，运行
C:\> cd "C:\Program Files\MySQL\MySQL Server 5.5\bin"
C:\> mysqld --init-file=C:\reset.txt

4、启动后，还不能马上用新密码连接数据库，需要重启mysql数据库

这是因为m2eclipse(maven插件)要在启动时需要进行的一个步骤。

This step can be disabled through the Eclipse preferences: Window / Preferences / Maven / "Download repository index updates on startup". This option is on the main "Maven" preference page (not a child page). Just uncheck the box to prevent this from happening.
我们可以停止这个动作。方法：Windows -> Preferences -> Maven 取消勾选 Download repository index updates on startup

我的做法是使用pdfclown来进行这项工作。官方网站是：https://pdfclown.org/ 先下载其最新版本。
参考其示例代码：https://pdfclown.org/2010/01/02/upcoming-0-0-8-whats-going-to-be-new/#more-30

使用这段代码，我们不仅可以得到文本的字符串，还能得到文本的页数和相对坐标。
我的思路是先把所有文本的字符串和坐标提取出来。然后排序，排序的顺序是纵坐标，然后横坐标。
这样排序完毕后，就能比较好的解决文本格式问题。
