测试事务配置是否成功 报[{dataSource-1} inited]

spring整合mybatis已成功，配置spring事务管理器时，用测试类测试向数据库插入数据，显示 [{dataSource-1} inited]
用代码块功能插入代码，请勿粘贴截图

1、spring-persist-tx.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </tx:attributes>
    </tx:advice>

</beans>

2、spring-persist-mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </bean>
    
    <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="dataSource"></property>
        
        <property name="plugins">
            <array>
                <bean  class="com.github.pagehelper.PageHelper">
                    <property name="properties">
                        <props>
                            
                            <prop key="dialect">mysql</prop>

    </bean>
    
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.atguigu.crowd.mapper"></property>
    </bean>
</beans>

3、测试类（其中除了testTx方法，其他测试方法都成功了）

package com.atguigu.crowd;

import com.atguigu.crowd.entity.Admin;
import com.atguigu.crowd.mapper.AdminMapper;
import com.atguigu.crowd.service.api.AdminService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.sql.DataSource;
import java.sql.Connection;
import java.sql.SQLException;

/**
 * @author 123
 * date 2022-09-18
 */
// 在类上标记必要的注解，spring整合junit
// 指定Spirng给Junit提供的运行器类
@RunWith(SpringJUnit4ClassRunner.class)
// 加载Spring配置文件的注解
@ContextConfiguration(locations = {"classpath:spring-persist-mybatis.xml", "classpath:spring-persist-tx.xml"})
public class CrowdTest {

    @Autowired
    private DataSource dataSource;

    @Autowired
    private AdminMapper adminMapper;

    @Autowired(required = false)
    private AdminService adminService;

    @Test
    public void testConnection() throws SQLException {
        Connection connection = dataSource.getConnection();
        System.out.println(connection);
    }

    @Test
    public void testTx() {
        Admin admin = new Admin(null, "jerry", "123456", "杰瑞", "jerry@qq.com", null);
        adminService.saveAdmin(admin);
    }

    @Test
    public void testInertAdmin() {
        Admin admin = new Admin(null, "nn", "123123", "汤姆", "tom@qq.com", null);
        int count = adminMapper.insert(admin);

        // 如果实际开发中，所有想查看数值的地方都用sysout方式打印，会给项目上线运行带来问题！
        // sysout本质上是一个IO的操作，通常IO的操作是比较小号性能的。如果项目中sysout很多，对性能的影响就很大了
        // 若使用日志系统，那么通过日志级别就能批量的控制信息的打印
        System.out.println("受影响的行数：" + count);
    }

}

我的解答思路和尝试过的方法

1、删除target，重新生成。无效。
2、重新敲一遍spring-persist-tx.xml。无效

我想要达到的结果

哪位朋友遇到过类似的问题呀，求解 ~
