一种实现方法是定义一个函数，该函数接收闭包旁边的输入参数（作为某种形式的键值），并使用evaluate函数在运行时定义给定的参数，从而使它们在闭包中可用。
类似于：

def withMyOwnVars(Map args, Closure body){
    args.each {
        // Define the name and value of the parameter. For strings, add quotes to make them evaluate correctly
        def paramName = it.key
        def paramValue = (it.value instanceof CharSequence) ? "'${it.value}'" : it.value

        // Run the evaluation of the parameter definition to make them available in the function's scope
        evaluate("${paramName} = ${paramValue}")
    }
    body()
}

// Usage will look like the following
withMyOwnVars(['myParam': 'my value', 'anotherParam': 6]) {
    println "I can now use myParam, and the value is ${myParam}"
    def result = 10 + anotherParam
}

或使用您要求的输入格式：

def withMyOwnVars(List args, Closure body){
    args.each { item ->
        def paramName = item[0]
        def paramValue = (item[1] instanceof CharSequence) ? "'${item[1]}'" : item[1]
        evaluate("${paramName} = ${paramValue}")
    }
    body()
}

// Usage will look like the following
withMyOwnVars([['myParam', 'my value'], ['anotherParam', 6]]) {
    println "I can now use myParam, and the value is ${myParam}"
    def result = 10 + anotherParam
}
