SpringBoot集成Mybati 配置多数据源参考上一篇文章
在Spring框架中使用MyBatis时，如果配置了多数据源，可能会导致之前配置的打印SQL语句的设置失效。这通常是因为在多数据源配置中，MyBatis的SQL打印功能只对默认数据源生效，而对于其他数据源，需要手动开启SQL打印。
1. 确保你已经在application.properties或application.yml中启用了MyBatis的SQL日志打印功能
# mybatis 配置
mybatis:type-aliases-package: com.roborock.framework.entitymapper-locations: classpath*:mappers/**/*.xmlconfiguration:log-impl: org.apache.ibatis.logging.stdout.StdOutImplmap-underscore-to-camel-case: true单数据源直接增加上面的配置mybatis.configuration.log-impl: org.apache.ibatis.logging.stdout.StdOutImpl 即可打印SQL语句
2. 多数据源时，只需要在其中的一个配置类中增加如下配置即可打印SQL语句，不需要在所有数据源配置中都增加
@Bean
@ConfigurationProperties(prefix = "mybatis.configuration")
public org.apache.ibatis.session.Configuration globalConfiguration() {return new org.apache.ibatis.session.Configuration();
}然后在其中一个配置类的SqlSessionFactory方法中增加入参Configuration configuration，使用bean.setConfiguration(configuration)即可！
完整代码如下：
package com.study.framework.config;import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.autoconfigure.jdbc.DataSourceProperties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;import javax.sql.DataSource;/*** @description rbk数据源配置类* //basePackages 自己mapper包路径*/
