按照你的方法我修改之后，我依然报错了：Description: file [E:\idea\workplace\mybatis_scoring_system\target\classes\com\cvte\mapper\UserMapper.class] required a single bean, but 2 were found: - sqlSessionFactoryBean: defined by method 'sqlSessionFactoryBean' in class path resource [com/cvte/config/MyBatisConfig.class] - sqlSessionFactory: defined by method 'sqlSessionFactory' in class path resource [com/cvte/config/MybatisInterceptorConfig.class] 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

这个错误提示是因为你在配置 MyBatis 的时候，定义了两个 SqlSessionFactory，导致 Spring 无法确定要使用哪个 SqlSessionFactory。

你可以在 MyBatis 的配置类中，使用 @Primary 注解来标记一个 SqlSessionFactory，表示它是首选的 SqlSessionFactory。例如：

@Configuration
@MapperScan("com.cvte.mapper")
public class MyBatisConfig {

    @Bean
    @Primary
    public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource) {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dataSource);
        sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mapper/*.xml"));
        return sqlSessionFactoryBean;
    }
}

这样，就可以将 sqlSessionFactoryBean 标记为首选的 SqlSessionFactory，其他地方如果需要使用 SqlSessionFactory，就可以使用 @Autowired 注解来获取 sqlSessionFactoryBean 对象了。
