Java project: campus errand management system (java + springboot + Vue + Maven + elementui + MySQL)

The front end uses vue+elementui, This system is only suitable for learning SpringBoot+VUE, The campus announcement will be added later 、 Campus snacks and other functions , I will continue to update the later code . The system is divided into administrators and students 、 Students are two roles added by administrators in the background .

Running environment :

Back end jdk1.8、maven3.5/3.6 mysql5.7 idea/eclipse

front end idea vue-cli node.js build vue Environmental Science webpack3.6.0 Specify the version
