Groovy为I/O操作提供了许多帮助方法,虽然你可以在Groovy中用标准Java代码来实现I/O操作,不过Groovy提供了大量的方便的方式来操作File、Stream、Reader等等。 读取文件 读取文本文件并打印每一行文本 new File(baseDir, 'haiku.txt').eachLine{ line ->
2.1. UsingFile.withReader Let’s start with theFile.withReadermethod.It creates a newBufferedReaderunder the covers that we can use to read the contents using thereadLinemethod. For example, let’s read a file line by line and print each line. We’ll also return the number of lines: ...
reader.read(buffer) return buffer } println reader//输出hello,world 这里是北京 an 如何拷贝文件? 我们写一个方法,把刚才的文件拷贝到另一个文件中去,代码如下: def copy(String sourcePath, String destPath) { try { //1 创建目标文件 def destFile = new File(destPath) if (!destFile.exists())...
