6. 斜线字符串
正如早先提到的，斜线可以用于定义字符串。用斜线定义字符串有一个优点：那就是，字符串本身的内容无需转义反斜线。比如：
def winpathQuoted = 'C:\\windows\\system32'
def winpathSlashy = /C:\windows\system32/
println winpathSlashy // C:\windows\system32
assert winpathSlashy ==~ '\\w{1}:\\\\.+\\\\.+'
assert winpathSlashy ==~ /\w{1}:\\.+\\.+/
7. 多行斜线字符串
斜线字符串还能够跨越多行。这一点对于多行正则表达式非常有用。比如：
def name = "vishal"
def path = "c:/groovy/"
def multilineslashy = /
Hello $name
path $path
dollar = $
path = c:\/groovy
/
println multilineslashy
输出为：
Hello vishal
path c:/groovy/
dollar = $
path = c:/groovy
8. 斜线字符串中的美元符号$
在多行斜线字符串中，如果字符串内出现斜线/，那么它需要被转义。另外，如果字符串内出现了$美元符号（没有用于表达式时），也需要转义，否则会报MissingPropertyException异常。比如：
def name = "vishal"
def path = "c:/groovy"
def multilineSlashy = /
Hello $name
path = $path
dollar = $test
path = c:\/groovy
/
println multilineSlashy
输出：
Exception thrown
