log4j.properties文件放在src下，系统启动时会默认加载

junit测试代码

package dao;import java.io.IOException;import org.apache.log4j.PropertyConfigurator;import org.junit.Test;import com.dao.AddressMapper;import com.model.Address;import com.util.BeanFactoryUtil;public class AddressMapperTest {@Testpublic void addressMapperTest() throws IOException{//可以手动加载//PropertyConfigurator.configure(UserMapperTest.class.getClassLoader().getResource("log4j.properties"));AddressMapper addressMapper=(AddressMapper)BeanFactoryUtil.getInstance().getBean("addressMapper");Address address=addressMapper.getAddressByAid(4);System.err.println("address======="+address.getAddress());}}

控制台打印的日志信息：
