在Bean注入時新增一行程式碼 

VFS.addImplClass(SpringBootVFS.class);

完整示例：

@Configuration
public class MybatisConfig {
    //DataSource配置
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource druidDataSource() {
        DruidDataSource druidDataSource = new DruidDataSource();
        return druidDataSource;
    }

    //提供SqlSeesion
    @Bean
    public SqlSessionFactory sqlSessionFactoryBean() throws Exception {

        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(druidDataSource());
        //新增一行如下程式碼
        VFS.addImplClass(SpringBootVFS.class);
        PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

        sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:mapper/*.xml"));
        sqlSessionFactoryBean.setTypeAliasesPackage("com.pojo");
        return sqlSessionFactoryBean.getObject();
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        return new DataSourceTransactionManager(druidDataSource());
    }
}
