log4j没在src根目录下而是在src/res里面出现下面情况

log4j:ERROR Ignoring configuration file [log4j.properties].
log4j:WARN No appenders could be found for logger (org.springframework.core.env.StandardEnvironment).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

解决：

在测试类中添加

import org.apache.log4j.PropertyConfigurator;

以及

@BeforeClass
    public static void setup() {
        PropertyConfigurator.configure("src/res/log4j.properties");
    }

然后就解决了

test代码

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.wy.dao.CustomerDao;
import com.wy.po.Customer;
import org.apache.log4j.PropertyConfigurator;
public class DaoTest {
	
	@BeforeClass
    public static void setup() {
        PropertyConfigurator.configure("src/res/log4j.properties");
    }
	
	@Test
	public void findCustomerByIdDaoTest() {
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("res/applicationContext.xml");
		CustomerDao customerDao = (CustomerDao) applicationContext.getBean("customerDao");
		Customer customer = customerDao.findCustomerById(1);
		System.out.println(customer);
		
	}
}
