java反射实现根据类名和方法名字符串调用
import java.lang.reflect.Method; public class Test { public static void main(String[] args) throws Exception { String className = "com.runqianapp.ngr.alias.example.FunClass"; String methodName = "sayHello"; Class clz = Class.forName(className); // Object obj = clz.newInstance(); //获取方法 Method m = obj.getClass().getDeclaredMethod(methodName, String.class); //调用方法 String result = (String) m.invoke(obj, "aaaaa"); System.out.println(result); } } class FunClass{ public String sayHello(String s){ System.out.println(s); return "hello!"; } }
