在src/main/resource下新建application.properties文件

spring.datasource.url=jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull
spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.view.prefix=/WEB-INF/templates/
spring.view.suffix=.jsp

配置类,springboot入口
