首先是pom依赖：

		<!-- mybatis -->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.2</version>
        </dependency>

		<!-- mysql5.x连接驱动 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.38</version>
        </dependency>
        
		<!--druid数据源 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.19</version>
        </dependency>

       其次是数据源和mybaits配置，下面以yml形式展示：

spring:
  #   数据源基本配置
  datasource:
    username: root
    password: 12345
    url: jdbc:mysql://localhost:3306/study?characterEncoding=UTF-8&useSSL=false
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    #   数据源其他配置
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    #   配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
    filters: stat,wall,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
# mybatis配置
mybatis:
  # config-location: classpath:mybatis/mapper/mybatis-config.xml
  # type-aliases-package: 
  # mapper-locations: classpath:mapper/*.xml
  configuration:
    map-underscore-to-camel-case: true
    cache-enabled: true

       方便项目的快速搭建。
