[解决办法]

引用:

你在代码里加个输出,看看语句 if(rs.getString("guige").trim().equals("PSP110-0.8(冷改穿)")) 是否是true.

对的，先按这种方法排查一下！看看究竟获取到值没。如果是false说明你后台处理有问题的！

[解决办法]
那这样试试:


 if(rs.getString("guige").trim().replaceAll("&nbsp;","").equals("PSP110-0.8(冷改穿)"))

[解决办法]
public static void main(String[] args){
System.out.println(" zz".trim().equals("zz"));
System.out.println(" zz".trim().equals(" zz"));
}
