log4j配置文件

### 设置###
log4j.rootLogger = debug,stdout

### 输出信息到控制抬 ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n

config.java（javaconfig方式）

@Configuration
@ComponentScan("com.xx")
@MapperScan("com.xx.dao")
public class Appconfig {


    @Bean
    public SqlSessionFactoryBean sqlSessionFactoryBean(DataSource dataSource){
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration();

        sqlSessionFactoryBean.setConfiguration(configuration);
        sqlSessionFactoryBean.setDataSource(dataSource);
        return sqlSessionFactoryBean;
    }

    @Bean
    public DataSource dataSource(){
        DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();

        return driverManagerDataSource;

Dao层

import org.apache.ibatis.annotations.Select;

import java.util.List;
import java.util.Map;

public interface IndexDao {

    @Select("select * from city")
    public List<Map<String,Object>> list();
}

Service层

@Service
public class IndexService {

    @Autowired
    IndexDao dao;

    public List<Map<String,Object>> list(){
        return dao.list();
    }
}

测试类

public class Test {

    public static void main(String[] args) {
        AnnotationConfigApplicationContext annotationConfigApplicationContext =
                new AnnotationConfigApplicationContext(Appconfig.class);
        System.out.println(annotationConfigApplicationContext.getBean(IndexService.class).list());
    }
}
