在Spring Web App中运行junit时，出现错误：java.lang.IllegalStateException：无法加载ApplicationContext

Question

我正在尝试为我的Web应用程序编写单元测试，尝试了很多方法，但是仍然出现错误，告诉我无法加载applicationContext文件UserService.java：

package com.baobaotao.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.baobaotao.dao.LoginLogDao;
import com.baobaotao.dao.UserDao;
import com.baobaotao.domain.LoginLog;
import com.baobaotao.domain.User;

@Service
public class UserService {

    @Autowired
    private UserDao userDao;

    @Autowired
    private LoginLogDao loginLogDao;

    public boolean hasMatchUser(String userName, String password) {
        int matchCount = userDao.getMatchCount(userName, password);
        return matchCount > 0;
    }

    public User findUserByUserName(String userName) {
        return userDao.findUserByUserName(userName);
    }

    public void loginSuccess(User user) {
        user.setCredits(5 + user.getCredits());
        LoginLog loginLog = new LoginLog();
        loginLog.setUserId(user.getUserId());
        loginLog.setIp(user.getLastIp());
        loginLog.setLoginDate(user.getLastVisit());
        userDao.updateLoginInfo(user);
        loginLogDao.insertLoginLog(loginLog);       
    }
}

Answer 1

在stacktrace中，有一条消息，提示缺少BasicDataSource类。

您的类路径上是否有Apache Commons DBCP jar ？
