求大神查看啊 , 谢谢啦

各路大神 帮小弟看看

自动注入userService的时候错了。你看看那里用了，贴出代码大家看看

package com.baobaotao.web; import java.util.Date; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.baobaotao.domain.User; import com.baobaotao.service.UserService; @Controller("loginController") public class LoginController{ @Autowired @Qualifier("userService") private UserService userService; @RequestMapping(value = "/index.html") public String loginPage(){ return "login"; } @RequestMapping(value = "/loginCheck.html") public ModelAndView loginCheck(HttpServletRequest request,LoginCommand loginCommand){ boolean isValidUser = userService.hasMatchUser(loginCommand.getUserName(), loginCommand.getPassword()); if (!isValidUser) { return new ModelAndView("login", "error", "用户名或密码错误。"); } else { User user = userService.findUserByUserName(loginCommand .getUserName()); user.setLastIp(request.getLocalAddr()); user.setLastVisit(new Date()); userService.loginSuccess(user); request.getSession().setAttribute("user", user); return new ModelAndView("main"); } } public UserService getUserService() { return userService; } public void setUserService(UserService userService) { this.userService = userService; } } 这是LoginController的全部代码

看看是不是UserService 没有声明注册成springbean

我在上面加了 @Service("userService")

[nyxiaobin123]

还想到2中可能性啊，经供参考，一个是你们UserService是接口类，注解放到实现类，还有就是是不是你的类没部署到tomcat里面啊？

第一种可能性,之前研究过 , 有做单元测试的 没问题 . 第二种可能性应该不会吧 ,我是用myeclipse发布到tomcat下的 , 发布到weblogic下也是报同样的错.

[酷酷小鱼]

问题终于解决了 !!!~~ 是web.xml中的 <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <param-value>classpath:applicationContext.xml</param-value> 这个写错了 我晕哦

[永远的EMT]

<param-value>classpath:applicationContext.xml</param-value> 这个怎么错了

[msmvc]

我也遇到的了类似的情况, 在写单元测试时 userService 自动注入时报错 原因是spring的自动扫描包的配置 <context:component-scan base-package="io.ifif.myapp" /> 放的地方不对 原来是放在了springmvc的配置文件中 (servlet-context.xml), 正常用web的controller访问是可以的 但是在单元测试时我直直接加载的spring的配置文件root-context.xml 解决方法是把自动扫描包的配置放到 root-context.xml中就OK了

[Y_Bei]

你是在写spring3.x的例子么？我也打完出现了一样的错误，请问你把配置那句改成什么了？

[a850254439]

我也出现了这个错误 有谁可以告诉你要怎么去改吗？

[请误操作]

我也遇到了这个问题，不能解决啊，谁能帮帮我

[qq_34476935]

我也是这个错误 找到了 我在 impl 中没有加注解 不知道你们怎么样

[qq_34934848]

他说说的是把classpath去掉

[byte[0]]

<param-value>classpath*:applicationContext.xml</param-value>
