Groovy:groovy.lang.MissingMethodException:没有方法的签名 [英] Groovy : groovy.lang.MissingMethodException: No signature of method

问题描述

我只是从常规开始.此错误看起来很基本.但我似乎没有解决这个问题.感谢任何指导我正确方向的帮助

I'm just starting with groovy. This error looks basic. but i don't seem to get through this. Appreciate any help in guiding me through the right direction

我正在定义一个类似于下面的字符串，并将其传递给testSender方法

I'm defining a string like below and passing it to testSender method

def line = "5 1 -81.42 Ido1"
testSender(line.toString())

testSender方法的定义

Definition of testSender method

def testSender(line){
     try {
         println line  
     } catch(e) {
         println e.printStackTrace()
     }
}

运行此命令时，出现此错误

When I run this, getting this error

groovy.lang.MissingMethodException: 
No signature of method: GroovySQLQuery$_main_closure1.testSender() 
is applicable for argument types: (java.lang.String) values: [5 1 -81.42 Ido1]

推荐答案

应为:

class GroovySQLQuery { 
    static void main(String[] args) { 
        def line = "5 1 -81.42 Ido1" 
        testSender(line.toString()) 
    } 

    static testSender(line) { 
        println line 
    } 
}
