一个springboot(collect springmvc、hibernate、modleView）+rmi远程调用天气预报系统的小项目

newsSystem

先放上作业的代码地址

新闻系统

下面是在centos服务器上部署环境，建一个新数据库用户进行管理

yum install mysql mysql-server mysql-devel
create user newsadmin;
create database newsbase;
grant all privileges on newsbase.* to newsadmin@localhost identified by'password';
revoke all on *.* from 'admin'@'%';
grant all on *.* to 'admin'@'%' identified by 'wdnm'
  • 数据库用户名，密码在application.yml文件中配置

yum install java-1.8.0-openjdk-devel
安装maven到usr/local/apache-maven
export MAVEN_HOME=/usr/local/apache-maven
export PATH=${MAVEN_HOME}/bin:$PATH
服务器端Could not find or load main class org.apache.maven.wrapper.MavenWrapperMain
错误解决：mvn io.takari:maven:wrapper
  • 环境变量别写错

    mysql服务没启动的错误，很奇妙
