@Bean(name = "dao")
    @Primary
    @Autowired
    public Dao primaryDao(@Qualifier("ds1DataSource") DataSource primaryDataSource, SqlManager sqlManager, DaoRunner daoRunner) {
        NutDao dao = new NutDao(primaryDataSource, sqlManager);
        dao.setRunner(daoRunner);
        return dao;
    }

@Qualifier("ds1DataSource") DataSource primaryDataSource,
这个名子使用 datasource 名子就行。
