使用Java的泛型和反射机制来实现，代码示例如下：

public class ObjectParameter {

    private String parameterName;
    private Class type;

    public ObjectParameter(String parameterName, Class type) {
        this.parameterName = parameterName;
        this.type = type;
    }

    public T getParameter(Object obj) throws IllegalAccessException, InvocationTargetException {
        Method method = null;
        T parameterValue = null;
        try {
            method = obj.getClass().getMethod("get" + parameterName);
            if(method.getReturnType().equals(type)) {
                parameterValue = (T) method.invoke(obj);
            }
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
        return parameterValue;
    }
}

使用时，可以创建一个ObjectParameter对象，指定参数名和类型，然后通过调用getParameter方法来获取参数值，例如：

User user = new User();
user.setName("Tom");
user.setAge(18);
ObjectParameter nameParameter = new ObjectParameter<>("Name", String.class);
String name = nameParameter.getParameter(user); // name = "Tom"
ObjectParameter ageParameter = new ObjectParameter<>("Age", Integer.class);
Integer age = ageParameter.getParameter(user); // age = 18
