groovy学习资料：

The Apache Groovy programming language - Documentation

GStringTemplateEngine (Groovy 4.0.0)

模版中map的处理可参考：

groovy-map.each{}_weixin_30687051的博客-CSDN博客

模版中list的处理可参考：

创建目录：

File dir=File.createTempFile('tmp', '', new File(“路径”))

dir.mkdirs()

在父目录下创建目录:

File childDir= new File(rootDir, “子目录名称”)
childDir.mkdirs()

在目录下创建文件并写入内容【写入一个xml文件，这边使用groovy进行字符串替换模版占位符】：

String yhXml=“ceshi/pom.xml”

Map model；//model中可以存储模版中对应的内容

groovy进行字符串替换模版占位符：

//处理模版源文件

//获取模版

GStringTemplateEngine  templateEngine=new GStringTemplateEngine()

Template template

def classLoader = GroovyTemplate.class.classLoader

def resource = classLoader.getResource(name)
if (resource) {
   template =engine.createTemplate(resource)
}

template =engine.createTemplate(name)

//字符串替换模版占位符

Writable writable=template.make(model)

def result = new StringWriter()
writable.writeTo(result)

String pom = new String(result.toString())

//在目录下将pom内容写入创建文件中

new File(childDir, 'pom.xml').write(pom)
