springboot 的一些常用配置

Idea版本：2020.2.3 Mysql版本：8.0.22-winx64

一、application.properties

jsp的参数

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

数据库链接必须的参数

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/how2java?characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=admin
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.properties.hibernate.hbm2ddl.auto=update

指明从哪里去找xml配置文件，同时指定别名

mybatis.mapper-locations=classpath:com/how2java/springboot/mapper/*.xml
mybatis.type-aliases-package=com.how2java.springboot.pojo
