class类:
public class Student { ???????public Student( ){ ???????System.out.println("public Student()"); ???} ???private void haha(){ ???????System.out.println("private void haha()"); ???}}
配置文件
class.properties
className=Day01.Student
methodName=haha
获取方法
//加载属性文件,取得类名的方法名 ?Properties props = new Properties(); ?InputStream is = new FileInputStream("src/Day01/class.properties");props.load(is); ?String className = props.getProperty("className").trim(); ?String methodName = props.getProperty("methodName").trim(); ?//通过反射,执行该类的方法 ?Class c = Class.forName(className); ?Constructor con = c.getConstructor(null); ?Method m = c.getDeclaredMethod(methodName,null);m.setAccessible(true); //方式属性是私有 ,如果是私有必须加上m.invoke(con.newInstance(null),null);
结果:
public Student()private void haha()
