使用 mybatis plus 動態數據源

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);
    }

}

這樣就可以使用動態數據源了。
