@IocBean(args = {"refer:dao"})
public class CmsUserServiceImpl extends BaseServiceImpl<cms_user> implements CmsUserService {
    public CmsUserServiceImpl(Dao dao) {
        super(dao);
    }

都有了啊 - - 我想实现nutzwk的base封装方式

报错之前的10行日志也贴一下

加个无参数构造方法试试


public class BaseServiceImpl<T> extends EntityService<T> implements BaseService<T>{ public BaseServiceImpl(Dao dao) { super(dao); } ... public interface BaseService<T> { Dao dao(); int count(Condition cnd);

TestModule贴来看看

@IocBean
@At("/test")
public class TestModule {
    private static final Log log = Logs.get();
    @Inject
    private CmsUserService userService;

    @At("/str")
    @Ok("json")
    public String  test1(){
        log.info("ll");
        return "guojxx";
    }

    @At("/jetx")
    @Ok("jetx:hello.jetx")
    public void  jext(){
    }

    @At("/dao")
    public Object  testDao(@Param("::user.")cms_user user){
        return  null;
    }

    @At("/ser")
    @Ok("json")
    public Object testSer(){
        return  userService.query(Cnd.where("id","=","1"),"roleId");
    }
}

额,是不是项目没clean啊... 看不出哪里问题

额额额。。。对maven不太熟悉 多模块项目我直接启动。。

执行一下clean和install

什么情况?
