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.String
import java.lang.GString
String#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
