### 步骤 ###

1.pom

<dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
        <version>1.1.16</version>
    </dependency>
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.3</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>

2.application.yml

spring:
      datasource:
        driverClassName: com.mysql.cj.jdbc.Driver
        type: com.alibaba.druid.pool.DruidDataSource
        url: jdbc:mysql://127.0.0.1:3306/demo?useUnicode=true&serverTimezone=GMT%2B8&characterEncoding=utf-8&allowMultiQueries=true&useSSL=false
        username: demo
        password: 1
    
        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
        maxPoolPreparedStatementPerConnectionSize: 20
        filters: stat,wall,log4j
        connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
        defaultAutoCommit: false
    
    mybatis:
      mapper-locations: classpath:mapper/*.xml

3.Database新建的数据库链接（EasyCode）
