MybatisSqlSessionFactoryBean 而不是 SqlSessionFactoryBean

    sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(mapperLocations));
    sessionFactory.setConfigLocation(new DefaultResourceLoader().getResource(configLocation));
    return sessionFactory.getObject();
