GroovyShell().parse传递参数 [英] GroovyShell().parse passing parameters

问题描述

我有一个Groovy脚本，需要从外部groovy脚本解析一个类.我不确定如何传递参数.这是有效的方法:

I have a groovy script that needs to parse a class from an external groovy script. I am not sure how to pass parameters. Here is what works:

我正在运行的Groovy脚本正在使用此行从external.groovy解析外部类:

Groovy script I am running is using this line to parse the external class from external.groovy:

new GroovyShell().parse(new File('External.groovy'))

这是external.groovy的样子:

Here is what external.groovy looks like:

class External {
    public external() {
        println "Hello"
    }
}

有效.

我遇到的问题，我找不到将参数传递给外部方法的方法.这是external.groovy的外观:

The problem I am having, I cant find a way to pass parameters to the external method. Here is what external.groovy should look like:

class External {
    public external(String name) {
        println name
    }
}

如何向正在运行的脚本中添加参数:

How do I add parameters to the running script:

new GroovyShell().parse(new File('external.groovy')) //need to include the 'Name' parameter to this

推荐答案

1. parse仅解析您的文件，不执行它
2. 您也必须拨打run
3. 您需要实例化文件，并且需要调用您的方法并为其指定参数
4. 您需要通过Binding对象提供参数

1. parse only parses your file and doesn't execute it
2. you have to call run as well
3. you need to instantiate your file AND you need to call your method and give it the parameter
4. you need to give the parameter via an Binding object

这是课程和电话

class External {
     public external(String name) {
        println name
    }
}
new External.external(somename)

然后

def bindings = new Binding()
bindings.setVariable("somename", "mrhaki")
def shell = new GroovyShell(bindings)
shell.parse(new File('external.groovy'))
shell.run()
