同学你好。同学是只有这一个页面乱码吗？还是只要点击了一次分类列表以后再点击别的页面也是乱码呢？祝学习愉快~

芝芝兰兰 2019-10-11 10:22:55

同学你好。可以尝试以下几步：

1、先清除缓存

1）将Tomcat停下，将曾经add进去的项目重新remove出来，然后在Tomcat上右键选择clean...

2）在Eclipse的头部导航中选择Project->clean...

3）然后在浏览器中使用Ctrl+Shift+Delete 清除缓存。将项目重新add到Tomcat中重启项目

2、在Chrome浏览器内的乱码页面上右键，选择查看网页源代码，或者使用快捷键Ctrl+U。看一下里面的编码方式是否为utf-8。

3、如果除了这个链接，其他都不乱码，把这个页面备份一下，删除后重新建一个jsp，然后把之前内容拷贝过来后保存。

如果解答了同学的疑问，望采纳~

祝学习愉快~

同学你好。同学使用的是Eclipse自带的浏览器呢，同学使用Chrome浏览器访问一下看看是否会有问题呢？祝学习愉快~

同学你好，控制台输出的list内容不是乱码的话，证明从数据库查询的数据不是乱码呢~同学可以尝试在下面红框位置添加一下字符编码过滤试试：

request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf8");
response.setContentType("text/html;charset=utf-8");

如果还是不行，请将项目目录都展开截图下~并附一下web.xml和Servlet的代码

祝学习愉快~

同学你好，问一下同学jsp页面中有乱码吗？如果有，建议同学复制源码中的页面替换一下。另外建议同学在链接数据库时，加上useUnicode=true&characterEncoding=UTF8，如：

如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~

不管是复制源码还是在连接数据库时加上那条语句，还是一样会乱码

登录进去就不会乱码，但是一点击分类列表就全乱码了

你好！可以把查询的数据输出到控制台，看一下是否乱码。另外，请把乱码的jsp页面贴出来，我们试一下。贴到回答里，不要贴到回复里，否则会失去格式。祝学习愉快！
