MainSetup贴一下

MainSetup如下：

package net.sll.nutzbook;

/**
 * Created by sll on 2017/5/2.
 */
import java.util.Date;
import org.nutz.dao.Dao;
import org.nutz.dao.util.Daos;
import org.nutz.ioc.Ioc;
import org.nutz.mvc.NutConfig;
import org.nutz.mvc.Setup;
import net.sll.nutzbook.bean.User;

public class MainSetup implements Setup {

    // 特别留意一下,是init方法,不是destroy方法!!!!!
    public void init(NutConfig nc) {
        Ioc ioc = nc.getIoc();
        Dao dao = ioc.get(Dao.class);
        // 如果没有createTablesInPackage,请检查nutz版本
        Daos.createTablesInPackage(dao, "net.wendal.nutzbook", 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);
        }
    }

    public void destroy(NutConfig nc) {
    }

}

改成你自己的package

Daos.createTablesInPackage(dao, "net.wendal.nutzbook", false);

搞定了 谢谢！
