I would like to make an indirect call to a java method, which name is specified in a .properties file.
How can I do that ?

3You could use [reflection](https://docs.oracle.com/javase/tutorial/reflect/). – Elliott Frisch Apr 27 '15 at 02:56

look at this link good example for .properties file http://stackoverflow.com/questions/1318347/how-to-use-java-property-files – Zealous System Apr 27 '15 at 03:02

Lets be clear here. You want to get the name of the method you are going to call from the properties file. This way any method might be invoked depending on how the properties file is configured. Right? – candied_orange Apr 27 '15 at 03:45

Do you know the name of the **class** on which you want to call this **method** ? – EpicPandaForce Apr 27 '15 at 07:45

Object object = // .....
try(is = propertiesInputStream()) {
Properties p = new Properties();
p.load(is);
Method m = org.springframework.util.ReflectionUtils.findMethod(object.getClass(), p.get("method"));
Object result = org.springframework.util.ReflectionUtils.invokeMethod(m, object);
}

`org.springframework.util.ReflectionUtils.findMethod`? What's the dependency on that one? – EpicPandaForce Apr 27 '15 at 07:44

I believe, you don´t need Spring for this, the JDK provides you with an API to do reflection and invoke methods (even if they are private). Let me look for it... – Victor Apr 27 '15 at 08:24
