	各路大神帮小弟看看
10分	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
	引用 2 楼 w3226327 的回复: 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

10分	看看是不是UserService 没有声明注册成springbean
	引用 5 楼 nyxiaobin123 的回复: 看看是不是UserService 没有声明注册成springbean 我在上面加了 @Service(“userService”)
20分	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？
	引用 7 楼 nyxiaobin123 的回复: 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.
	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
