    公司正在考虑引用Nutz，让我来研究如何使用Nutz！于是我找来“Nutzbook”手册向导，来一步步建立一个web工程，但是到编写第一个模块类UserModule的时候，遇到了下列问题(之前的步骤全都正确执行，tomcat也能正常启动无报错)

    1. 异常信息

  1. 各个文件
    (1) MainModule.java
    package net.wendal.nutzbook;

import org.nutz.mvc.annotation.IocBy;
import org.nutz.mvc.annotation.Modules;
import org.nutz.mvc.annotation.SetupBy;
import org.nutz.mvc.ioc.provider.ComboIocProvider;

@SetupBy(value=MainSetup.class)
@IocBy(type=ComboIocProvider.class,args={"*js","ioc/","*anno","net.wendal.netzbook","*tx"})

@Modules(scanPackage=true)
public class MainModule {
}

(2)MainSetup.java
public class MainSetup implements Setup{

@Override
public void destroy(NutConfig conf) {
    // TODO Auto-generated method stub
}

@Override
public void init(NutConfig conf) {
    Ioc ioc = conf.getIoc();
    Dao dao = ioc.get(Dao.class);
    Daos.createTablesInPackage(dao, "net.wendal.netzbook", false);

    //初始化默认根用户
    if(dao.count(User.class) == 0){
       User user = new User();
       user.setName("admin");
       user.setPassword("123456");
       user.setCreateTime(new Date());
       user.setUpdateTime(new Date());
       dao.insert(user);
    }
}

}

求解答，如还需要知道些什么信息，请告知，谢谢！

UserModule 文件加 @IocBean了么

@IocBy(type=ComboIocProvider.class,args={"*js","ioc/","*anno","net.wendal.netzbook","*tx"})

应该是

@IocBy(type=ComboIocProvider.class,args={"*js","ioc/","*anno","net.wendal.nutzbook","*tx"})

应该是

@IocBy(type=ComboIocProvider.class,args={"*json","ioc/","*anno","net.wendal.nutzbook","*tx"})

@Rekoe *js 与 *json 等价的

@Rekoe 详细定义在ComboIocLoader里面, 里面有全部缩写

            loaders.put("js", JsonLoader.class);
            loaders.put("json", JsonLoader.class);
            loaders.put("xml", XmlIocLoader.class);
            loaders.put("annotation", AnnotationIocLoader.class);
            loaders.put("anno", AnnotationIocLoader.class);
            loaders.put("trans", TransIocLoader.class);
            loaders.put("tx", TransIocLoader.class);
            try {
                loaders.put("cache",
                            (Class<? extends IocLoader>) Lang.loadClass("org.nutz.jcache.NutCacheIocLoader"));
            }
            catch (ClassNotFoundException e) {}
            try {
                loaders.put("quartz",
                            (Class<? extends IocLoader>) Lang.loadClass("org.nutz.integration.quartz.QuartzIocLoader"));
            }
            catch (ClassNotFoundException e) {}

@wendal 好
