我定义了以下变量:
def VAL1 = 'foo'
def VAL2 = 'bar'
def s2 = 'hello ${VAL1}, please have a ${VAL2}'
使这种替换起作用的最简单方法是什么?我如何构建 GStrings2
并对其进行评估?(VALs 和 s2 是从数据库中加载的,此代码段仅用于演示我的问题。)
如果可以SimpleTemplateEngine
将变量放入 Map?
import groovy.text.SimpleTemplateEngine
def binding = [ VAL1:'foo', VAL2:'bar' ]
def template = 'hello ${VAL1}, please have a ${VAL2}'
println new SimpleTemplateEngine().createTemplate( template ).make( binding ).toString()
编辑
您可以使用绑定而不是地图,因此以下在 groovyconsole 中有效:
// No def. We want the vars in the script's binding
VAL1 = 'foo'
VAL2 = 'bar'
def template = 'hello ${VAL1}, please have a ${VAL2}'
// Pass the variables defined in the binding to the Template
new SimpleTemplateEngine().createTemplate( template ).make( binding.variables ).toString()
那么:
def VAL1 = 'foo'
def VAL2 = 'bar'
def s2 = "hello ${VAL1}, please have a ${VAL2}".toString()
?
注意:注意双引号
