springboot小项目总结

软件：Postman、Xmind、WinScp、intelliJ idea 、navicate、swagger2接口开发工具、linux。

项目搭建：配置文件

 1.注解使用@Mapper，爆红版本支持问题。找到支持@Mapper版本的依赖文件

 2.springboot项目打成war包使用的几个条件：加依赖、修改启动类、打包方式<Packing>改为war：https://blog.csdn.net/qq_23934475/article/details/81776037

3.Linux上环境搭建：jdk下载、tomcat、mysql

tar -zxvf apache-tomcat-9.0.34.tar.gz
mv apache-tomcat-9.0.34 tomcat
cd /tomact/bin
./startup.sh
service stop firewalld.service
service disable firewalld.service
firewall-cmd --state
./startup.sh

wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
tar -xzvf  mysql-5.7.26-linux-glibc2.12-x86_64.tar.gz
groupadd mysql
useradd -r -g mysql mysql
chown -R mysql.mysql /usr/local/mysql
mkdir data
yum install libaio
/usr/local/mysql/bin/mysqld --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data --initialize
vi /etc/my.cnf

[mysqld]
datadir=/usr/local/etc/mysql/data
basedir=/usr/local/etc/mysql
socket=/tmp/mysql.sock

# skip-grant-tables
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
/usr/local/mysql/bin/mysql -uroot -p
vi /etc/profile
export PATH=/usr/local/etc/mysql/bin
source /etc/profile
mysql -u root -p

4.将war包部署到tomcat下的webapps下。
