SpringBoot配置之：0配置也躲不过配置

# 开发环境配置
server:# 服务器的HTTP端口&＃xff0c;默认为80port: 80
数据源

现在流行用 druid 直接配置 &＃xff08;&＃xff09;

# Spring配置
spring:# 数据源datasource:type: com.alibaba.druid.pool.DruidDataSourcedriverClassName: com.mysql.cj.jdbc.Driverdruid:# 主库数据源url: jdbc:mysql://localhost:3306/test?useUnicode&＃61;true&characterEncoding&＃61;utf8&zeroDateTimeBehavior&＃61;convertToNull&useSSL&＃61;true&serverTimezone&＃61;GMT%2B8username: rootpassword: root


因为数据源的配置内容还是比较多&＃xff0c;一般习惯单独分个文件出来。详情见&＃xff1a;SpringBoot 配置之&＃xff1a;数据源配置

只配置必要的内容&＃xff1a;&＃xff08;详见&＃xff1a;SpringBoot 配置之&＃xff1a;Mybatis配置&＃xff09;

# MyBatis
mybatis:# 搜索指定包别名 &＃xff08;实体类所在的位置&＃xff09;typeAliasesPackage: com.example.demo.entity# 配置mapper的扫描&＃xff0c;找到所有的mapper.xml映射文件。 ** 可以匹配子目录mapperLocations: classpath*:mapper/**/*Dao.xml# Sql日志输出
logging:level:com.example.demo.mapper: trace # *Mapper.java 文件所在的包路径

完整依赖文件

pom.xml 中除了 阿里数据库连接池druid 是手动加的&＃xff0c;其它都是官方生成向导时勾选的。
因为要用到mybatis所以勾选了&＃xff1a;jdbc、mysql、mybatis
