使用 mybatis plus 动态数据源

1.pom.xml 增加

 <dependency>

            <groupId>com.baomidou</groupId>

            <artifactId>dynamic-datasource-spring-boot-starter</artifactId>

            <version>2.5.3</version>

        </dependency>

2.配置 application.yml

spring:

  datasource:

    dynamic:

      druid:

          initial-size: 0

          max-active: 8

          min-idle: 2

          max-wait: -1

          min-evictable-idle-time-millis: 30000

          max-evictable-idle-time-millis: 30000

          time-between-eviction-runs-millis: 0

          validation-query: select 1

          validation-query-timeout: -1

          test-on-borrow: false

          test-on-return: false

          test-while-idle: true

          pool-prepared-statements: true

          max-open-prepared-statements: 100

          filters: stat,wall

          share-prepared-statements: true

      datasource:

        master:

          url: jdbc:mysql://localhost:3306/wuxianji?useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=GMT%2B8

          username: root

          password: root

          druid:

            initial-size: 5

3.修改 SpringBootApplication 注解配置

import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)

public class DemoApplication {

    public static void main(String[] args) {

        SpringApplication.run(DemoApplication.class, args);

    }

}

这样就可以使用动态数据源了。
