Groovy 字符串那点儿事儿

可以直接用+

assert ‘ab‘ == ‘a‘ + ‘b‘

支持多行

def aMultilineString = ‘‘‘line one
line two
line three‘‘‘

 out:

Fri Jan 03 11:14:58 CST 2020: INFO: line one
line two
line three

如果定义多行字符串时有缩进，可以去掉，下面俩方法就行

import java.lang.Stringimport java.lang.GStringString#stripIndent()
String#stripMargin()

巧合了，字符在行开头，下面两种一样

def aMultilineString1 = ‘‘‘
line one
line two
line three‘‘‘

def aMultilineString2 = ‘‘‘\n
line one
line two
line three‘‘‘

log.info aMultilineString1
log.info aMultilineString2

让字符串里出现 引号 和反斜杠

下面这些是用反斜杠也能出现在字符串里
