3，logback.xml 日志输出文件，可直接在控制台输出sql,非常方便
<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
<!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
<property name="LOG_HOME" value="/test/log" />
<!-- <contextName>car-trace-logging</contextName>
设置变量，下面有用到。含义是日志保存路径

<!-- 控制台输出 -->

<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">

4，controller
package com.xdzo.fsf.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
import com.xdzo.fsf.domain.City;
import com.xdzo.fsf.service.CityService;
@RestController
@RequestMapping("/cityController")
public class CityController {
@Autowired
private CityService cityService;
//查询所有的用户
@GetMapping("/findCityById")
public City findUserById(@RequestParam("id") Long id) {
System.out.println(id);
return cityService.getCityById(id);
}
@RequestMapping("/showCity")
public List<City> showCity() {
List<City> list = cityService.getAllList();
System.out.println(list);
for(City c:list){
System.out.println("abc");
}
return list;
}
}
5,service
package com.xdzo.fsf.service;
import java.util.List;
import com.xdzo.fsf.domain.City;
public interface CityService {
public List<City> getAllList();
public City getCityById(Long id);
}
6,serviceImpl
package com.xdzo.fsf.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.xdzo.fsf.dao.CityDao;
import com.xdzo.fsf.domain.City;
@Service
public class CityServiceImpl implements CityService {
@Autowired
private CityDao cityDao;
public CityDao getCityDao() {
return cityDao;
}
public void setCityDao(CityDao cityDao) {
this.cityDao = cityDao;
}
@Override
public List<City> getAllList() {
return cityDao.selectAllCity();
}
@Override
public City getCityById(Long id) {
return cityDao.selectCityById(id);
}
}
7,dao
package com.xdzo.fsf.dao;
import java.util.List;
import com.xdzo.fsf.domain.City;
public interface CityDao {
public List<City> selectAllCity();
public City selectCityById(Long id);
}
8,mapper映射文件，放在resources下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xdzo.fsf.dao.CityDao">
<resultMap id="CityResultMap" type="com.xdzo.fsf.domain.City" >
<id column="id" property="id" jdbcType="BIGINT" />
<result column="city_name" property="city_name" jdbcType="VARCHAR" />
<result column="city_code" property="city_code" jdbcType="VARCHAR" />
</resultMap>
<select id="selectAllCity" resultMap="CityResultMap">
select * from city
</select>
<select id="selectCityById" parameterType="long" resultMap="CityResultMap">
select * from city where id=#{id,jdbcType=BIGINT}
</select>
</mapper>
9，数据库表
运行结果：
控制台信息输出：
非常详细，很方便查看sql运行等
直接创建，复制就可以使用，后面就可以按照自己的开发方式开发了，这个也是初创，当笔记了，有不对的地方，望大家多多指正，共同进步
