CXF webservice服务端查询数据库出错

hannah837 2013-07-23 02:05:18

准备用webservice做一个单点登录系统，对外发布了一个webservice，服务端与客户端的通讯没有问题，但是服务端实现类访问数据库的时候会出现invocation target exception，就像spring没有注入一样。

接口如下：



package com.x.member0.service;

import javax.jws.WebService;

import com.yuanhua.member0.entity.User;

@WebService

public interface IUserService {

	/**

	 * 验证用户信息 getAuthentication

	 * 

	 * 

	 *@param item

	 * 

	 */

	public  User getAuthentication(User item);

服务端实现类如下：



package com.x.member0.service.impl;



import java.util.List;



import javax.jws.WebService;



import com.x.common.dao.ICommonDao;

import com.x.common.dao.sqlimpl.CommonDaoSqlImpl;

import com.x.common.service.BaseService;

import com.x.member0.entity.User;

import com.x.member0.service.IUserService;



/**

 * 用户信息dao UserDao

 * 

 *  

 * 

 */

@WebService(endpointInterface = "com.x.member0.service.IUserService")

public class UserServiceImpl extends BaseService implements IUserService {

	 



	/*

	 * (non-Javadoc)

	 * @see

	 * com.yuanhua.member1.service.impl.IUserDao#getAuthentication(com.yuanhua

	 * .member0.entity.User)

	 */

	public User getAuthentication(User item) {

		String hql = "from User where loginName='" + item.getLoginName()

				+ "' and userPwd='" + item.getUserPwd() + "' and isDeleted=0";

		 

		 User u = (User) this.getCommonDao().obj(hql);//无法访问dao层

		return item;

	}

客户端：



package aa;



import org.springframework.context.ApplicationContext;

import org.springframework.context.support.FileSystemXmlApplicationContext;



import com.x.member0.entity.User;

import com.x.member0.service.IUserService;



public class TestClient {



	public static void main(String[] args) {

		testWebserviceClient();

	}



	public static void testWebserviceClient() {

		// 加载客户端配置文件

		ApplicationContext context = new FileSystemXmlApplicationContext(

				"src/applicationContext.xml");

		// 获取webservice接口

		IUserService service = (IUserService) context

				.getBean("yhProtalWebservice");

		User item = new User();

		item.setLoginName("admin");

		item.setUserPwd("admin");

		User u = service.getAuthentication(item);

		System.out.println(u);

运行后，客户端的值可以很顺利的传到服务端，无论传字符串、对象、集合都可以。
服务端实现类里面写死一个值，也可以顺利的传回客户端，webservice通讯应该是没有问题。
但是一旦到了访问数据库的，就是调用dao层的方法，就会出现invocation target exception，就像spring没有注入一样。但是spring中我肯定注入过这个bean。

控制台报错如下
