SpringBoot 配置文件以及依赖 加上跨域配置文件

配置目录：

application.properties的配置

#设置服务端口号
server.port = 8090

#配置数据源
spring.datasource.driver-class-name = org.mariadb.jdbc.Driver
spring.datasource.url = jdbc:mariadb://localhost:3306/数据库名
spring.datasource.username = root
spring.datasource.password = 123456

#连接池
spring.datasource.type=com.mchange.v2.c3p0.ComboPooledDataSource

# 配置 mybatis
mybatis.config-location=classpath:mybatis/mybatis-config.xml
# 设置 别名类型包 (实体类)
mybatis.type-aliases-package=com.hjb.carsales.entity
# 设置 mybatis 映射 的 SQL语法 xml文件
mybatis.mapper-locations=classpath:mapper/*.xml

#设置日志
logging.config=classpath:mybatis/logback-spring.xml

#JpaRepository save()加上下面一句话 才起作用
spring.jpa.hibernate.ddl-auto = update

#配置分页
pagehelper.helper-dialect= mariadb
pagehelper.reasonable= true

#如果是mariadb，需要配置如下
spring.jpa.database-platform=org.hibernate.dialect.MariaDB10Dialect
