SpringBoot整合Mybatis访问数据库和阿里巴巴数据源

Posted 2021-03-01 讲文明懂礼貌

1、pom文件加入依赖

<!--加入mybatis依赖-->
        <!--引入satrter-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.2</version>
        </dependency>
        <!--mysql的jdbc驱动-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <scope>runtime</scope>
        </dependency>
        <!--引入第三方数据源-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.8</version>
        </dependency>

2、application.properties配置文件

#===============================数据库相关======================================

#数据库驱动（可以自动识别）
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/databaseName?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
spring.datasource.username=username
spring.datasource.password=password
#修改数据源(com.zaxxer.hikari.HikariDataSource)
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

useUnicode=true&characterEncoding=UTF-8：防止中文乱码
serverTimezone=UTC：设置时间，UTC是世界标准时间
未设置时间报数据库连接错误：The server time zone value ‘?й???????‘ is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration

3、添加mapper扫描

@MapperScan("mapper包路径")

4、开发mapper
