（1）将logback集成到junit中

package com.liutao.utils;

import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.core.joran.spi.JoranException;
import org.junit.runners.model.InitializationError;
import org.slf4j.LoggerFactory;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * 将logback集成到junit中
 *
 * @author LIUTAO
 * @version 2017/5/11
 * @see
 * @since
 */
public class JUnit4ClassRunner extends SpringJUnit4ClassRunner {
    static{
        LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
        JoranConfigurator configurator = new JoranConfigurator();
        configurator.setContext(lc);
        lc.reset();
        try {
            configurator.doConfigure("src/main/resources/conf/logback.xml");
        } catch (JoranException e) {
            e.printStackTrace();
        }
    }
    public JUnit4ClassRunner(Class<?> clazz) throws InitializationError {
        super(clazz);
    }
}

（2）添加单元测试

package com.liutao.test;

import com.liutao.dao.UserDao;
import com.liutao.entity.User;
import com.liutao.mapper.UserMapper;
import com.liutao.utils.JUnit4ClassRunner;
import junit.framework.TestCase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.web.WebAppConfiguration;

/**
 * 测试类
 *
 * @author LIUTAO
 * @version 2017/4/20
 * @see
 * @since
 */
@RunWith(JUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(locations = {"classpath:conf/applicationContext.xml"})
public class TestUser extends TestCase {
    private Logger logger = LoggerFactory.getLogger(TestUser.class);
    @Autowired
    private UserMapper userMapper;

    @Autowired
    private UserDao userDao;

    @Test
    public void findUser() throws Exception {
        logger.debug("the user is "+userMapper.getUsersByName("zhangfei"));
        logger.debug("the user is "+userMapper.getUsersByName("zhangfei"));
//        userMapper.updateUser(new User("张三丰",11,"zsf123",1));
    }

    @Test
    public void testFindUserByIdOfJpa(){
        logger.debug("this user was found by jpa is "+userDao.findUserById(1));
        logger.debug("this user was found by jpa is "+userDao.findUserById(1));
    }
}
