配置yml文件，链接数据库配置

spring：
  datasource:
    hikari:
      taodx:
        driver-class-name: com.mysql.jdbc.Driver
        jdbc-url: jdbc:mysql://localhost:3306/taodx?useUnicode=true&characterEncoding=utf8&useSSL=false
        username: root
        password: 123456

配置数据源文件

@Configuration
public class DataSourceConfig {
    @Bean(name = "taodxDataSoure")
    @ConfigurationProperties(prefix = "spring.datasource.hikari.taodx")
    public DataSource taodx(){
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "dynamicDataSource")
    @Primary
    public DataSource dynamicDataSource(){
        DynamicDataSource dynamicDataSource = new DynamicDataSource();
        dynamicDataSource.setDefaultTargetDataSource(taodx());
        Map<Object, Object> dsMap = new HashMap<>();
        dsMap.put("taodxDataSoure", taodx());
        dynamicDataSource.setTargetDataSources(dsMap);
        return dynamicDataSource;
    }
    
    /**
     * 根据数据源创建SqlSessionFactory
     */
    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dynamicDataSource());
        return sqlSessionFactoryBean.getObject();
    }

    /**
     * 配置事务管理器
     */
    @Bean
    public DataSourceTransactionManager transactionManager() throws Exception {
        return new DataSourceTransactionManager(dynamicDataSource());
    }
}
