@Inject 注入 还是报空指针

@wendal 你的意思是UserMastManagerBiz 是手动new的，不是注入的吗？

@wendal /*
* 本配置文件声明了整个应用的数据库连接部分。
*/
var ioc = {

dataSource : {
    type : "com.alibaba.druid.pool.DruidDataSource",
    fields : {
       driverClass : "oracle.jdbc.driver.OracleDriver",
       jdbcUrl : "jdbc:oracle:thin:@:1521:orcl",
       user : "",
       password : ""
    } 
},
dao : {
    type : "org.nutz.dao.impl.NutDao",
    args : [ {
       refer : "dataSource"
    } ]
}

};

我在js中没有声明bean，全都是以注入方式写的

这里是生成了这个userManagerServiceImpl 这个对象吧

@wendal

@Controller
@RequestMapping("/home")
public class Home {

private Logger logger = Logger.getLogger(Home.class);

@Inject
private UserManagerServiceImpl  userManagerService;

/**
 * 个人日记-注册页面
 * 
 * @return
 * @Description:
 */
@RequestMapping(value = "/{site}/register" , method = RequestMethod.GET)
public ModelAndView register(HttpServletRequest request,
       HttpServletResponse response) {
    logger.info("进入注册页   register START");
    ModelAndView mav = new ModelAndView();
    mav.setViewName("homePage/registerPage");
    logger.info("进入注册页   register End");
    return mav;
}

/**
 * 个人日记-正在注册
 * 
 * @return
 * @Description:
 */
@SuppressWarnings("unused")
@RequestMapping(value = "/{site}/registering" , method = RequestMethod.POST)
public ModelAndView registering(HttpServletRequest request,
       @RequestParam("email") String email,
       @RequestParam("username") String nickName,
       @RequestParam("password") String password,
       HttpServletResponse response) {
    logger.info("正在注册   registering START");
    ModelAndView mav = new ModelAndView();
    mav.setViewName("homePage/registerPage");

    email = email==null?"":email.trim();
    nickName = nickName==null?"":nickName.trim();
    password = password==null?"":password.trim();

    UserRegisterServiceRequestDTO requestDTO = new UserRegisterServiceRequestDTO();
    requestDTO.setEmail(email);
    requestDTO.setNickName(nickName);
    requestDTO.setPassword(password);

    if(requestDTO != null){
       userManagerService.addUser(requestDTO);
       mav.setViewName("redirect:/home/homePage/logining.do");
    }else{
       mav.addObject("errorTips", "您输入数据有误!");
       request.getSession().setAttribute("information", null);
    }

    logger.info("正在注册   registering End");
    return mav;
}

}

@wendal 直接用Mvcs.ctx().getDefaultIoc(UserManagerServiceImpl.class)将
@Inject
private UserManagerServiceImpl userManagerService; 替代吗？

@wendal

现在又出现一个问题:当我在类中直接使用
Mvcs.ctx().getDefaultIoc(UserManagerServiceImpl.class) 时，会出现
Multiple markers at this line
- Syntax error on token "ctx", Identifier expected after this
token
- Syntax error on token ".", { expected

请问这是什么原因？

@wendal

改成 Mvcs.ctx.getDefaultIoc(UserManagerServiceImpl.class);
会出现
Syntax error on token "getDefaultIoc", Identifier expected after this token

这也是版本问题吗

@wendal

打扰你很久了，可是改成
Mvcs.ctx.getDefaultIoc.get(UserManagerServiceImpl.class);
还是报Syntax error on tokens, delete these tokens

我用的是nutz-1.b.51.jar

@wendal

谢谢啦，麻烦你这么久，问题终于解决了。
学习nutz有段时间了，现在在做毕设，正在搭环境，不想用SSH,所以想用新学的nutz做一下，毕竟用SSH的同学太多了，也找个机会练练手，看看自己对nutz掌握的怎样了。
最后由衷说一声： 谢谢啦！！！！！

@wendal

是eclipse ，可能是我对nutz还不太熟吧，所以卡壳的地方比较多
