Spring Boot集成MyBatis Plus与ShardingSphere数据源配置失败求助

我正在使用Spring Boot 3.1.4框架集成MyBatis Plus 3.5.3和ShardingSphere 4.1.0，实现MySQL一主一从读写分离。主库部署在本地localhost:3306，从库通过Docker映射到localhost:3309，两个数据库均为MySQL 8.0+版本，本地可正常登录。

启动项目时出现如下错误：

描述：
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
原因：Failed to determine a suitable driver class

主启动类 #

package com.mercurows;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

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

import lombok.extern.slf4j.Slf4j;

@Slf4j
// @SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)
// @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
@SpringBootApplication
public class RwDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(RwDemoApplication.class, args);
        log.info("项目启动成功。。。");
    }
}

已尝试的解决方案 #

• 使用@SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)
• 使用@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
• 在mybatis-plus-boot-starter中添加排除依赖配置
• 修改部分依赖版本

期望项目正常启动，实现主从数据库读写分离，求可行的解决方案。
