使用的最新的nutzboot，我在NutDaoStarter的getDao方法打了断点都不进来，很奇怪

getDao 和 injectManyDao 都没进来

知道了，必须要先使用默认的dao，才可以注入其他的dao

但是我发现many的多注入貌似还是有问题，会注入jdbc.为前缀的

@wendal 请问DataSourceStater里的这段 case "com.alibaba.druid.pool.DruidDataSource": 是不是始终只取同一个DataSource

public static DataSource createDataSource(Ioc ioc, PropertiesProxy conf, String prefix) {
        switch (conf.get(prefix + "type", "druid")) {
        case "simple":
        case "org.nutz.dao.impl.SimpleDataSource":
            SimpleDataSource simpleDataSource = new SimpleDataSource();
            String jdbcUrl = conf.get(PRE + "jdbcUrl", conf.get(PRE + "url"));
            if (Strings.isBlank(jdbcUrl)) {
                throw new RuntimeException("need " + PRE + ".url");
            }
            simpleDataSource.setJdbcUrl(jdbcUrl);
            simpleDataSource.setUsername(conf.get(PROP_USERNAME));
            simpleDataSource.setPassword(conf.get(PROP_PASSWORD));
            return simpleDataSource;
        case "druid":
        case "com.alibaba.druid.pool.DruidDataSource":
            DataSource ds = ioc.get(DataSource.class, "druidDataSource");
            String[] tmp = ioc.getNamesByType(DruidPasswordCallback.class);
            for (String beanName : tmp) {
				if (!Strings.isBlank(beanName))
					((DruidDataSource)ds).setPasswordCallback(ioc.get(DruidPasswordCallback.class, beanName));
			}
            return ds;
        case "hikari":
        case "com.zaxxer.hikari.HikariDataSource":
            return ioc.get(DataSource.class, "hikariDataSource");
        default:
            break;
        }

知道了，看来DataSourceStarter也要改下才能支持many的注入

期待你的修改，我暂时没有多数据源的场景

正在改，等下就提交

@wendal 已提交，麻烦审核下

好的

已合并^_^

请问多久可以mvn -U

大概10分钟

吼吼，美得很，问题完美解决

Good

@wendal 只是还有一个不太科学的问题，那就是必须要先注入默认的dao，才会触发manyDao的注入，有没有什么方法可以规避

因为你写在getDao方法里面了

你可以这样试试

@IocBean(create="init")
public class NutDaoStarter {

     public void init() {
         injectManyDao();
     }

然后getDao方法里面就不要调用injectManyDao()了

不知道void方法是否可以注解iocbean，如果可以，我就把injectManyDao直接从getDao方法里抽取出来

不能的... 那样行不通的

按你说的方式提交了

合并了^_^
