SpringBoot+Mybatis-plus(多数据源配置)

SpringBoot+Mybatis-plus(多数据源配置)

1.添加依赖

<dependency>
   <groupId>com.baomidou</groupId>
   <artifactId>mybatis-plus-boot-starter</artifactId>
   <version>3.4.1</version>
</dependency>
<!--多数据源配置-->
<dependency>
   <groupId>com.baomidou</groupId>
   <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
   <version>2.4.2</version>
</dependency>
<!--P6SPY SQL 语句拦截-->
<dependency>
   <groupId>p6spy</groupId>
   <artifactId>p6spy</artifactId>
   <version>3.8.0</version>
</dependency>
<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <scope>8.0.20</scope>
</dependency>

2.添加依赖

spring:
  datasource:
    p6spy: true
    dynamic:
      datasource:
        master:
          username: root
          password: 12345678
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://127.0.0.1:3306/数据库1(默认)?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowMultiQueries=true&allowPublicKeyRetrieval=true&serverTimezone=Asia/Shanghai
        booking_car:
          username: root
          password: 12345678
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://127.0.0.1:3306/数据库2?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowMultiQueries=true&allowPublicKeyRetrieval=true&serverTimezone=Asia/Shanghai

3.serviceImpl实现

/**
 * @author MWX
 * @since 2021-02-18
 */
@Service
@RequiredArgsConstructor
@DS("booking_car")//动态切换默认数据库到booking_car
public class OrderServiceImpl implements OrderService {
    
    

    private final OrderDao orderDao;

    @Override
    public OrderEntity getUser(Long id) {
    
    
        return orderDao.selectById(id);
    }
}

4.测试同一项目连多个数据库效果

我也找了另一篇博文作为参考
