我没看到nutz字样

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.nutz.plugin.spring.boot.NutzDaoAutoConfiguration': Unsatisfied dependency expressed through field 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'io.shardingsphere.shardingjdbc.spring.boot.SpringBootConfiguration': Initialization of bean failed; nested exception is java.lang.NullPointerException

@wendal 大佬这个算吗

报错的是shardingsphere的类，不是nutz的

看看啥是啥变量为null吧，shardingsphere的配置文件都放好了？

配置放好了，只是转成dataSource的时候，调用了nutz的方法，启动就报错了


    @Bean
    public Dao myDao( SqlManager sqlManager, DaoRunner daoRunner) throws IOException, SQLException {
        DataSource dataSource = YamlShardingDataSourceFactory.createDataSource(ResourceUtils.getFile("classpath:sharding.yml"));
        NutDao dao = new NutDao(dataSource, sqlManager);
        dao.setRunner(daoRunner);
        return dao;
    }

怎么还调用YamlShardingDataSourceFactory？

读取分表的配置信息啊

sb本身有集成呀，当成普通数据源注入就行啊，肯定不要手动创建啊
