目的：用于查询翻页无法带参数的问题，可以用此解决，POJO.toSelect() 获取GET的查询URL

	public String toSelect() {
		StringBuffer sb = new StringBuffer();
		Field[] fields = Game.class.getDeclaredFields();
			for(Field field : fields){
				try{
				if(field.getType() == int.class){
					if(field.getInt(this) != 0){
						sb.append("&" + field.getName() + "=" + field.getInt(this));
					}
				}else if(field.getType() == String.class){
					if((String)field.get(this) != null && !"".equals((String)field.get(this))){
						sb.append("&" + field.getName() + "=" + field.get(this));
					}
				}else{
					continue;
				}
				}catch(Exception ex){
					continue;
				}
			}
		return sb.toString();
	}
