前文：

maven的核心功能在于pom.xml文件对jar包的依赖、继承、管理。

一、maven管理目录

二、安装配置

主要是配置中央和本地仓库

三、创建一个maven——springboot工程

1.pom.xml核心：继承父类工程版本控制、导入依赖jar包

2.启动类@SpringBootApplication

@注解根据：导入的jar包和application.properties的参数 底层自动配置和扫描包，减少了大量手动配置的xml文件

3.application.properties配置文件

mysql和mybatis需要手动设置参数

#端口、路径、springmvc视图解析器
    server.port=8006
    server.contextPath=/
    spring.mvc.view.prefix=/WEB-INF/views/
    spring.mvc.view.suffix=.jsp
    
    #mysql
    spring.jpa.database = MYSQL
    spring.datasource.url = jdbc:mysql:///zzydb?useUnicode=true&characterEncoding=utf8&autoReconnect=true&allowMultiQueries=true
    spring.datasource.username =root
    spring.datasource.password =root
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    
    #jap
    spring.jpa.hibernate.ddl-auto=update
    mybatis.typeAliasesPackage=com.richtime.common.pojo
    mybatis.mapperLocations=classpath:mapper/*.xml
    mybatis.configuration.mapUnderscoreToCamelCase=true
    mybatis.configuration.cacheEnabled=false
