网页显示如下。辛苦老师了

已经在群里回答你了，可以参照网友文章，将tomcat的url设置为支持中文

https://blog.csdn.net/smilefyx/article/details/70918025

老师，仍会报错

代码也有相应的转码操作

浏览器：http://localhost:8080/cityinfo/info_SearchShow.action?searchInfo.subsql=info_content&searchInfo.sqlvalue=师&searchInfo.type=like&showType=link&showpage=2

应该也没有乱码，但就是第二页没显示出来 

   请求 URL: http://localhost:8080/cityinfo/info_SearchShow.action?searchInfo.subsql=info_title&searchInfo.sqlvalue=工程师&searchInfo.type=like&showType=link&showpage=2

1. 说明tomcat设置不成功，仍然不能识别中文url

2. 不要用get请求传中文，用decode和encode转码。
