反射实现的通用toString()方法

每次实现Object的toString()方法很麻烦，所以通过反射写了个通用的toString()方法

public String toString() {

		StringBuffer buffer = new StringBuffer();

		Class clazz = getClass();
		String fullName = clazz.getName();
		int position = fullName.lastIndexOf(".");
		String shortName = fullName.substring(position + 1);

		buffer.append(shortName);
		buffer.append(": [");

		Field[] fields = clazz.getDeclaredFields();
		Field.setAccessible(fields, true);
		for (int i = 0; i < fields.length; i++) {
			Field field = fields[i];
			try {
				buffer.append(field.getName());
				buffer.append("=");
				buffer.append(field.get(this));
				buffer.append(", ");
			} catch (IllegalArgumentException e) {
				e.printStackTrace();
			} catch (IllegalAccessException e) {
				e.printStackTrace();
			}
		}
		buffer.setLength(buffer.length() - 2);
		buffer.append("]");

		return buffer.toString();
	}
