今天完成的事情：
完成静态页面改成动态页面
看别的师兄日报,还需要一个优秀学学员表
插入以下数据
添加el表达式
输入结果如下
期间又一次遇到1366错误数据插入失败,明知道是编码问题但是忘记怎么改了,为此浪费了不少时间,这次把修复过程放上来
====================================================
设置数据库编码为UTF-8:
修改/etc/mysql/my.conf文件
在末尾添加:
然后重新创建表
并在末尾加上
ENGINE=InnoDB DEFAULT CHARSET=utf8;
然后git推送代码的时候遇到了问题,也把过程放上来
git的使用
一台新电脑首先创建公钥
rm -rf /home/fanchen/ss.sh
先删除原来的公匙
ssh-keygen -t rsa -C "github账号邮箱"
生成公匙,一直确定
cat /home/fanchen/.ssh/id_rsa.pub
打开公匙文件
点击setting然后点击ssh and keys
点击new SSH key
输入title(谁便起)
输入id_rsa.pub的内容
完成
如果输入git push -u origin master提示
sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey).
可以执行以下语句
ssh -T git@git.coding.net
或者
ssh -vT git@git.coding.net
我们可能看到如下语句:
OpenSSH_7.2p2 Ubuntu-4ubuntu2.1, OpenSSL 1.0.2g 1 Mar 2016

debug1: /etc/ssh/ssh_config line 19: Applying options for *

debug1: No more authentication methods to try.

解决办法是输入:
eval "$(ssh-agent -s)"
我们会看到
Agent pid xxxxx
继续输入:
ssh-add
最后显示如下即成功
ssh-add /home/chen/.ssh/bitbucket.id_rsa.pub
然后去试试推送文件吧.

=====================================================
明天计划的事情：
完成tiles页面的复用
遇到的问题：
因为我建了两个表,一个是专业表,一个是优秀学生表,所以需要同时遍历两个数据表,
我新建了Pp_number类
准备遍历出'专业'表的'人数'字段
但是报异常了
Caught exception while allowing TestExecutionListener

明天再看看
收获：
对SSM框架更熟悉了,也学会了简单的使用EL表达式
----------------------------------------------------------------------------------------
代码链接放的是最早的代码,还有很多多余的地方没删除,
看师兄日报知道师兄已经工作了,好厉害
我也要努力啊
