框架整合的配置SSS
2017-09-29 09:55
274 查看
这是一个基于Spring的框架 表现层利用SpringMVC 服务层利用Spring 在持久层利用SpringData 关于数据库有两种情况，这一次的框架整合时基于关系型的数据库MySQL的整合，下面就直接占代码，关于一些注意的点，以及一些别的内容会在注释中详细的给出，若有不足或者是写错的地方，请多多指教，留下你宝贵的意见
这次使用的工具是IDEA，代码使用到的是Maven这个自动化的构建工具
（一）：关于pom.xml文件，连接了本地仓库以及关联了远程仓库

（三）：applicationContext.xml的配置
<?xml version="1.0" encoding="UTF-8"?>

<!--开启视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>
（四）持久层的代码
package com.qf.dao;
import com.qf.pojo.MyCity;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import javax.transaction.Transactional;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
public interface MyCityDao extends JpaRepository<MyCity,Long> {
//这样就已经具备了CRUD和分页查询的功能
//占位符的两种方式命名占位符和索引占位符
//添加不具备的功能，例如模糊查询,命名占位符，一一对应的形式
@Query("from MyCity where cityName like %?1%")
public List<MyCity> findLikeCity(String cityName);
//方式二
@Query("from MyCity where cityDesc=:cityDesc")
public List<MyCity> findLikeByDescCity(@Param("cityDesc") String cityDesc);
//这种方式其注解与其冒号后边的内容为一一对应
//一种是利用自带的CRUD，另一种方式，可以自己写更新语句
@Transactional
@Modifying
@Query("update MyCity set cityDesc =?1 where cid=?2")
public void updateCity(String cityDesc,Long cid );
}
（五）：服务层的代码（注：关于服务层的接口，就不在这儿写了，都是先写接口，再写实现）
package com.qf.service;
import com.qf.dao.MyCityDao;
import com.qf.dto.MyCityDto;
import com.qf.pojo.MyCity;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;
import java.util.ArrayList;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
@Service
public class MyCityServiceImpl implements MyCityService {
//利用注解的形式去注入dao层
@Autowired
private MyCityDao myCityDao;
public void setMyCityDao(MyCityDao myCityDao) {
this.myCityDao = myCityDao;
}
public void addCity(MyCityDto dto) {
MyCity pojo=new MyCity();
BeanUtils.copyProperties(dto,pojo);
myCityDao.save(pojo);
}
public void updateCity(MyCityDto dto) {
MyCity pojo=new MyCity();
BeanUtils.copyProperties(dto,pojo);
myCityDao.saveAndFlush(pojo);
}
public void deleteCity(Long id) {
myCityDao.delete(id);
}
public MyCityDto findByIdCity(Long id) {
MyCity myCity = myCityDao.findOne(id);
MyCityDto dto= new MyCityDto();
BeanUtils.copyProperties(myCity,dto);
return dto;
}
public List<MyCityDto> findAllCity() {
List<MyCity> myCities = myCityDao.findAll();
List<MyCityDto> list= new ArrayList<MyCityDto>();
for (MyCity myCity : myCities) {
MyCityDto dto= new MyCityDto();
BeanUtils.copyProperties(myCity,dto);
list.add(dto);
}
return list;
}
public List<MyCityDto> findByPage(int page, int size) {
Pageable pageable= new PageRequest(page,size);
List<MyCityDto> list= new ArrayList<MyCityDto>();
Page<MyCity> cities = myCityDao.findAll(pageable);
int totalPages = cities.getTotalPages();//获取总的页数
List<MyCity> content = cities.getContent();//这才是获取到数据
for (MyCity myCity : content) {
MyCityDto dto= new MyCityDto();
BeanUtils.copyProperties(myCity,dto);
list.add(dto);
}
return list;
}
}
（六）：表现层
package com.qf.action;
import com.qf.dao.MyCityDao;
import com.qf.dto.MyCityDto;
import com.qf.service.MyCityService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
@Controller
public class MyCityAction {
@Autowired
private MyCityService myCityService;
public void setMyCityService(MyCityService myCityService) {
this.myCityService = myCityService;
}
//@Qualifier("myCityService")这个是绝对定位的意思
@RequestMapping("/addCity.do")
public ModelAndView addCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
String cityName = request.getParameter("cityName");
String cityDesc = request.getParameter("cityDesc");
MyCityDto dto= new MyCityDto();
dto.setCityDesc(cityDesc);
dto.setCityName(cityName);
myCityService.addCity(dto);
mv.setViewName("/findAllCity.do");
return mv;
}
@RequestMapping("/deleteCity.do")
public ModelAndView deleteCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
return mv;
}
@RequestMapping("/updateCity.do")
public ModelAndView updateCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
return mv;
}
@RequestMapping("/findAllCity.do")
public ModelAndView findAllCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
List<MyCityDto> city =myCityService.findAllCity();
mv.addObject("list",city);
mv.setViewName("/ListCity.jsp");
return mv;
}
}
（七）：测试代码
package com.qf.test;
import com.qf.dao.MyCityDao;
import com.qf.pojo.MyCity;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
public class test {
@Test
public void addCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
MyCity city= new MyCity();
city.setCityDesc("坐上那火车去拉萨");
city.setCityName("西藏");
dao.save(city);
}
@Test
public void deleteCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
dao.delete(2L);
}
@Test
public void updateCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
MyCity city= new MyCity();
city.setCid(3L);
city.setCityName("新疆");
city.setCityDesc("地大物博");
dao.saveAndFlush(city);
}
@Test
public void findCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
MyCity daoOne = dao.findOne(3L);
System.out.print(daoOne.getCityDesc()+"\t"+daoOne.getCityName());
}
@Test
public void findAllCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
List<MyCity> daoAll =dao.findAll();
for (MyCity myCity : daoAll) {
System.out.println(myCity.getCityDesc()+"\t"+myCity.getCityName());
}
}
//分页查询数据
@Test
public void findByPageCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
Pageable pageable = new PageRequest(0,2);
//此处的分页查询与别的地方有所不同，其第一页从0开始，
// 第二页在page 的位置输入1即可，不用自己去计算
Page<MyCity> cities = dao.findAll(pageable);
int totalPages = cities.getTotalPages();
//获取总页数的方法
for (MyCity city : cities) {
System.out.println(city.getCityDesc()+"\t"+city.getCityName());
}
}
}

（四）持久层的代码
package com.qf.dao;
import com.qf.pojo.MyCity;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import javax.transaction.Transactional;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
public interface MyCityDao extends JpaRepository<MyCity,Long> {
//这样就已经具备了CRUD和分页查询的功能
//占位符的两种方式命名占位符和索引占位符
//添加不具备的功能，例如模糊查询,命名占位符，一一对应的形式
@Query("from MyCity where cityName like %?1%")
public List<MyCity> findLikeCity(String cityName);
//方式二
@Query("from MyCity where cityDesc=:cityDesc")
public List<MyCity> findLikeByDescCity(@Param("cityDesc") String cityDesc);
//这种方式其注解与其冒号后边的内容为一一对应
//一种是利用自带的CRUD，另一种方式，可以自己写更新语句
@Transactional
@Modifying
@Query("update MyCity set cityDesc =?1 where cid=?2")
public void updateCity(String cityDesc,Long cid );
}
（五）：服务层的代码（注：关于服务层的接口，就不在这儿写了，都是先写接口，再写实现）
package com.qf.service;
import com.qf.dao.MyCityDao;
import com.qf.dto.MyCityDto;
import com.qf.pojo.MyCity;
import org.springframework.beans.BeanUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;
import java.util.ArrayList;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
@Service
public class MyCityServiceImpl implements MyCityService {
//利用注解的形式去注入dao层
@Autowired
private MyCityDao myCityDao;
public void setMyCityDao(MyCityDao myCityDao) {
this.myCityDao = myCityDao;
}
public void addCity(MyCityDto dto) {
MyCity pojo=new MyCity();
BeanUtils.copyProperties(dto,pojo);
myCityDao.save(pojo);
}
public void updateCity(MyCityDto dto) {
MyCity pojo=new MyCity();
BeanUtils.copyProperties(dto,pojo);
myCityDao.saveAndFlush(pojo);
}
public void deleteCity(Long id) {
myCityDao.delete(id);
}
public MyCityDto findByIdCity(Long id) {
MyCity myCity = myCityDao.findOne(id);
MyCityDto dto= new MyCityDto();
BeanUtils.copyProperties(myCity,dto);
return dto;
}
public List<MyCityDto> findAllCity() {
List<MyCity> myCities = myCityDao.findAll();
List<MyCityDto> list= new ArrayList<MyCityDto>();
for (MyCity myCity : myCities) {
MyCityDto dto= new MyCityDto();
BeanUtils.copyProperties(myCity,dto);
list.add(dto);
}
return list;
}
public List<MyCityDto> findByPage(int page, int size) {
Pageable pageable= new PageRequest(page,size);
List<MyCityDto> list= new ArrayList<MyCityDto>();
Page<MyCity> cities = myCityDao.findAll(pageable);
int totalPages = cities.getTotalPages();//获取总的页数
List<MyCity> content = cities.getContent();//这才是获取到数据
for (MyCity myCity : content) {
MyCityDto dto= new MyCityDto();
BeanUtils.copyProperties(myCity,dto);
list.add(dto);
}
return list;
}
}
（六）：表现层
package com.qf.action;
import com.qf.dao.MyCityDao;
import com.qf.dto.MyCityDto;
import com.qf.service.MyCityService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
@Controller
public class MyCityAction {
@Autowired
private MyCityService myCityService;
public void setMyCityService(MyCityService myCityService) {
this.myCityService = myCityService;
}
//@Qualifier("myCityService")这个是绝对定位的意思
@RequestMapping("/addCity.do")
public ModelAndView addCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
String cityName = request.getParameter("cityName");
String cityDesc = request.getParameter("cityDesc");
MyCityDto dto= new MyCityDto();
dto.setCityDesc(cityDesc);
dto.setCityName(cityName);
myCityService.addCity(dto);
mv.setViewName("/findAllCity.do");
return mv;
}
@RequestMapping("/deleteCity.do")
public ModelAndView deleteCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
return mv;
}
@RequestMapping("/updateCity.do")
public ModelAndView updateCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
return mv;
}
@RequestMapping("/findAllCity.do")
public ModelAndView findAllCity(HttpServletRequest request){
ModelAndView mv= new ModelAndView();
List<MyCityDto> city =myCityService.findAllCity();
mv.addObject("list",city);
mv.setViewName("/ListCity.jsp");
return mv;
}
}
（七）：测试代码
package com.qf.test;
import com.qf.dao.MyCityDao;
import com.qf.pojo.MyCity;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import java.util.List;
/**
* Created by Administrator on 2017/9/28.
*/
public class test {
@Test
public void addCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
MyCity city= new MyCity();
city.setCityDesc("坐上那火车去拉萨");
city.setCityName("西藏");
dao.save(city);
}
@Test
public void deleteCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
dao.delete(2L);
}
@Test
public void updateCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
MyCity city= new MyCity();
city.setCid(3L);
city.setCityName("新疆");
city.setCityDesc("地大物博");
dao.saveAndFlush(city);
}
@Test
public void findCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
MyCity daoOne = dao.findOne(3L);
System.out.print(daoOne.getCityDesc()+"\t"+daoOne.getCityName());
}
@Test
public void findAllCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
List<MyCity> daoAll =dao.findAll();
for (MyCity myCity : daoAll) {
System.out.println(myCity.getCityDesc()+"\t"+myCity.getCityName());
}
}
//分页查询数据
@Test
public void findByPageCity(){
ClassPathXmlApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml");
MyCityDao dao = context.getBean(MyCityDao.class);
Pageable pageable = new PageRequest(0,2);
//此处的分页查询与别的地方有所不同，其第一页从0开始，
// 第二页在page 的位置输入1即可，不用自己去计算
Page<MyCity> cities = dao.findAll(pageable);
int totalPages = cities.getTotalPages();
//获取总页数的方法
for (MyCity city : cities) {
System.out.println(city.getCityDesc()+"\t"+city.getCityName());
}
}
}
