我在跟nutzbook走一遍教程,然后在登录的时候出现了dao为null的情况,下面是我的代码:
MainModule:

// 请注意星号!!不要拷贝少了
@IocBy(type=ComboIocProvider.class, args={
        "*js", "ioc/",
        "*anno", "net.wendal.nutzbook",
        "*tx",
        "*quartz"})
@Modules(scanPackage = true)
@SetupBy(value = MainSetup.class)
@ChainBy(args="mvc/nutzbook-mvc-chain.js")
public class MainModule {
}

昨天是好的,但是今天就坏了,不知道哪里搞错了...

哪个类的dao是null?

按nutzbook教程走,写了跟BaseModule,里面放了Dao

@IocBean
public class BaseModule {

    /** 注入同名的一个ioc对象 */
    @Inject
    protected Dao dao;

}

我看日志nutz没有打印获取的数据库版本啥的,应该是不正常吧

日志里面没有异常.

MainSetup.init方法已经调用过dao操作, 并没有抛异常,你多虑了.

那我什么原因啊...

你访问啥东西?报啥错误? 贴出来啊

我访问login方法,然后断点看到dao是null,然后抛出空指针


@IocBean
@At("/user")
@Ok("json:{locked:'password|salt',ignoreNull:true}")
//@Ok("json")
@Fail("http:500")
@Filters(@By(type=CheckSession.class, args={"me", "/"}))
public class UserModule extends BaseModule{


    @At("/")
    @Ok("jsp:jsp.user.list")
    public void index(){

    }

    @Filters()
    @At
    public Object login(@Param("username")String username,@Param("password") String password,HttpSession session){
        User user = dao.fetch(User.class, Cnd.where("name", "=", username).and("password", "=", password));
        if(user==null){
            return false;
        }else{
            session.setAttribute("me",user.getId());
            return true;
        }
    }
}

挖槽找到问题了....妈的倒错包了....

import org.nutz.ioc.loader.annotation.Inject;

@Inject
    protected Dao dao;

倒成这个了...
@com.google.inject.Inject
