cfx Spring 和 Spring MVC一起用报错

yangxiao_livecom 2012-11-22 11:05:44
问题描述：
在做WebService的时候，用CFX技术和Spring进行整合，然后通过WebService的方法调用业务逻辑代码，发现用Spring的依赖注入没有成功（失效）。去调web.xml中有关WebService代码，程序运行成功。

web.xml文件如下



<?xml version="1.0" encoding="UTF-8"?>

Controller代码


@Controller

@RequestMapping("/user")

public class UserController {

	

	private IUserService userServer;

	private IDeptService deptServer;

	

	public IDeptService getDeptService() {

		return deptServer;

	}



	public void setDeptService(IDeptService deptServer) {

		this.deptServer = deptServer;

	}



	public IUserService getUserService() {

		return userServer;

	}



	public void setUserService(IUserService userServer) {

		this.userServer = userServer;

	}



	@RequestMapping(value="/login",method=RequestMethod.POST)

	public String login(@RequestParam String name,@RequestParam String password,Model model,HttpServletRequest request) throws Exception{

		TUser user1 = userServer.getUserByName(name);

		if(user1 == null) {

			model.addAttribute("message", "用户不存在");

			return "login";

		}else if(password == null || !password.equals(user1.getPassword()) ){

			model.addAttribute("message", "密码错误");

			return "login";

		}else {

			request.getSession().setAttribute(Constants.USER_INFO_SESSION, user1);

			return "welcome";

		}

	}

以下略...


上面代码中 login（）方法时，userServer为null,注入没有成功，请问为何

谢谢楼上各位的回贴，在web.xml文件中注释掉WebService相关配置，或者两者都单独运行都能成功 spring配置文件如下：

WebService代码： 

@WebService(endpointInterface = "hy.ea.service.Login", serviceName = "Login")
public class LoginImpl implements Login {
 
	public String login(TUser user) {
		try {
			if(null == user)
				return "传入User为空";
			TUser user1 = userServer.getUserByName(user.getName());
			if(user1 != null)
				return "成功";
			else{
				return "调用返回空";
			}
		} catch (Exception e) {			
			e.printStackTrace(); 
			return e.getMessage();
		} 
	}
	
	private IUserService userServer;

	/**
	 * @return the userServer
	 */
	public IUserService getUserServer() {
		return userServer;
	}

	/**
	 * @param userServer the userServer to set
	 */
	public void setUserServer(IUserService userServer) {
		this.userServer = userServer;
	}
}
UserService代码如下： 

@Service("userServer")
public class UserServiceImpl implements IUserService {
	
	private IUserDao userDao;
	
	public IUserDao getUserDao() {
		return userDao;
	}

	public void setUserDao(IUserDao userDao) {

	}

	public void addUser(TUser user) throws Exception {

	}

	public void deleteUser(int id) throws Exception {
		userDao.delete(getUserById(id));
	}

	public TUser getUserById(int id) throws Exception {
		return userDao.findById(id);
	}
	
	public TUser getUserByName(String name) throws Exception {
		List list = userDao.findByName(name);
		return list==null || list.size() == 0 ? null : (TUser)list.get(0);
	}

	public List<TUser> getUserList() throws Exception {
		return userDao.findAll();
	}

	public void updateUser(TUser user) throws Exception {
		userDao.merge(user);
	}
}

@Repository("userDao")
public class UserDaoImpl extends HibernateDaoSupport implements IUserDao {
	
	private static final Logger log = LoggerFactory.getLogger(UserDaoImpl.class);
	protected void initDao() {
	}

关键的SPRING配置不给，怎么让别人排错？ 据我经验 你那就没注入

IUserService userServer这个实现类有没有问题？ spring配置文件里注册了它吗？ 还是使用注解的？
cfx集成spring mvc
前言 由于公司项目年代久远还在使用JAX-RS框架写rest接口，平时开发使用起来并不方便，例如获取request对象步骤繁琐，上传文件还需要添加依赖，新模块的接口还需要写配置rs.xml等等；中途简单尝试过两次都失败了，在某次新开excel导入接口，写上传文件写到崩溃，下定决心进行集成。 MAVEN依赖： <!--spring 4.3.13--> <dependency> <groupId>org.springframework</groupId>
spring mvc 3.2 使用总结
用spring mvc有一段时间了，今天有时间对这个框架的一些使用进行一些总结。 官网上面对spring mvc有一个很详细的demo，地址： https://github.com/SpringSource/spring-mvc-showcase 就拿这个例子作为总结的代码。 1.首先介绍一下WebApplicationInitializer，可以通过下面的代码来实现对spring s
