如何使用Java中的GroovyScriptEngine加载字符串输入（groovy脚本）

Question

I have a string input, which is a groovy script, which contains one or more methods like :

def printHello()
{
    println("Inside printHello()")
}

def setData(String str)
{  
    println("Incoming data : " + str)
}

This is in a string format, which is my input.

From a Java program, I want to load this string by using GroovyScriptEngine.

I am able to load and invoke the above methods by using GroovyClassLoader successfully.

new GroovyClassLoader().parseClass(scriptStr)

Unfortunately, by using GroovyScriptEngine , I cannot able to load the string.

I stored this string input into a temporary groovy file and tried to load. It is working.

But my intention is to load a string input directly by using GroovyScriptEngine.

Is there any way to load groovy script content as string input to the GroovyScriptEngine instead of using a file path?

Please help me on this...

Note : This is for my comparison study between GroovyClassLoader and GroovyScriptEngine.

Answer 1

GroovyClassLoader can load the class directly but cannot handle it dependency. GroovyScriptEngine can only load the script but not the class. However, it can handles class dependency and hot reloading.
