Description:


Method annotationDrivenTransactionManager in com.test.yuhua.service.config.mybatis.MyBatisCommonConfig required a single bean, but 2 were found:
- commonDataSource: defined by method 'commonDataSource' in com.test.yuhua.service.config.mybatis.MyBatisCommonConfig
- dynamicDataSource: defined by method 'dynamicDataSource' in com.test.yuhua.service.config.mybatis.MyBatisSlaveConfig




Action:


Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

解决方法：

package com.test.yuhua.dashboard.config;

import org.mybatis.spring.boot.autoconfigure.MybatisAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.Configuration;

@Configuration
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class,MybatisAutoConfiguration.class})
public class SpringBeanConfig {

}
