如果注释掉这行:

//nb.getAppContext().setMainPackage("xin.epei.starter");

就没有错误。不知道错误出在哪?

mainlaucher往上放package,不要在api里

        nb.run();
    }

    public void init() {
        System.out.println("xin.epei.api started....");
    }

    public void depose() {
    }
}

找到问题了,这个开始类,并不能加@IocBean,代码如下即可:

@AdaptBy(type = JsonAdaptor.class)
@SetupBy(value = MainSetup.class)
@Modules
@IocBy(args = {"*slog"})
public class MainLauncher {
    @Inject("refer:$ioc")
    private Ioc ioc;
    @Inject
    private PropertiesProxy conf;
    protected List<Setup> setups;

    public static void main(String[] args) throws Exception {
        NbApp nb = new NbApp().setArgs(args).setPrintProcDoc(true);
        nb.getAppContext().setMainPackage("xin.epei.starter");
        nb.run();
    }
}
