log4j.logger.org.mybatis=DEBUG

# console log
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c - %m%n


log4j.appender.DAILY_ALL=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DAILY_ALL.layout=org.apache.log4j.PatternLayout
log4j.appender.DAILY_ALL.layout.ConversionPattern="%p %d{yyyy-MM-dd HH\:mm\:ss} [%t] %-50.50c(%L) - %m%n
log4j.appender.DAILY_ALL.file=${search1.root}/WEB-INF/log/console.log

10，项目架构如下

11，配置mapper文件

<select id="selectUserById" parameterType="int" resultMap="userResultMap">
        select 
        <include refid="solumnBase"></include>
         from user where id = #{id}
    </select>

12，mapper类

User selectUserById(int id);

13,service实现类，注解注入DAO

@Service
public class UserServiceImpl implements UserService {

	@Autowired
	private UserMapper userMapper;
	
	public User selectUserById(int id) {
		return userMapper.selectUserById(id);
	}

}

14，controller类

@Controller
public class UserController {

	@Autowired
	private UserService userService;
	
	@ResponseBody
	@RequestMapping("/user")
	public String getUserById() {
		return userService.selectUserById(1).toString();
	}
	
}

15测试搭建好的框架

16，测试通过
