图书管理(spring+springMVC+mybatis整合)
对于三个框架学习以后,发现配置是一个很繁琐的过程,写一个整合记录,好让自己和需要的人学习学习.
首先用的是Oracle的数据库.
#准备工作
这是BookInfo表
这是BookTypeInfo表
两个表的主键都是ID,有自增的序列.没有增加触发器.
用最简单的表来做框架的整合.
导入相关jar包
#开始编程
首先创建文件夹还有基本的实体类
把接口和实现分成两个包,便于以后类多的时候查找,model里面就是放Oracle对应的实体类(对应的列名还有get、set方法)
编写mybatis里面对应的mapper
先写mapper文件,待会dao的实现就是使用mapper
IBookInfoMapper文件
public interface IBookInfoMapper {
//增加图书信息
public boolean addBook(BookInfo bookInfo);
//删除图书信息
public boolean delBook(int id);
//修改图书信息
public boolean editBook(BookInfo bookInfo);
//获取图书列表
public List getAllBook();
//获取某本图书
public BookInfo getBook();
}
这个是mybatis里面mapper都需要的
编写的BookInfoMapper.xml
select seq_bookId.nextval from dual
insert into bookInfo values (#{id},#{bookTypeInfo.id},#{bookName},#{author},#{price})
delete from BookInfo where id = #{id}
update BookInfo set bookTypeid =#{bookTypeInfo.id},bookName=#{bookName},author=#{author},price =#{price} where id = #{id}
因为后面要用到图书类型的下拉框,所以就顺便吧IBookTypeInfoMapper和BookTypeInfoMapper.xml写了
IBookTypeInfoMapper文件:
public interface IBookTypeInfoMapper {
//得到所有图书类型
public List getBookTypeList();
}
BookTypeInfoMapper.xml文件:
编写dao和service(实现类加上spring注解)
IBookInfoDao和IBookInfoMapper除了类名其他都一样,这里就不写了.
BookInfoDaoImpl文件:
package dao.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import mapper.IBookInfoMapper;
import model.BookInfo;
import dao.inter.IBookInfoDao;
@Repository
public class BookInfoDaoImpl implements IBookInfoDao{
@Autowired
//具体由我们配置好的mybatis的mapper来实现
private IBookInfoMapper iBookInfoMapper;
@Override
public boolean addBook(BookInfo bookInfo) {
// TODO Auto-generated method stub
return iBookInfoMapper.addBook(bookInfo);
}
@Override
public boolean delBook(int id) {
// TODO Auto-generated method stub
return iBookInfoMapper.delBook(id);
}
@Override
public boolean editBook(BookInfo bookInfo) {
// TODO Auto-generated method stub
return iBookInfoMapper.editBook(bookInfo);
}
@Override
public List getAllBook() {
// TODO Auto-generated method stub
return iBookInfoMapper.getAllBook();
}
@Override
public BookInfo getBook(int id) {
// TODO Auto-generated method stub
return iBookInfoMapper.getBook(id);
}
}
BookTypeInfoDaoImpl文件:
package dao.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import mapper.IBookTypeInfoMapper;
import model.BookTypeInfo;
import dao.inter.IBookTypeInfoDao;
@Repository
public class BookTypeInfoDaoImpl implements IBookTypeInfoDao{
@Autowired
private IBookTypeInfoMapper iBookTypeInfoMapper;
@Override
public List getBookTypeList() {
// TODO Auto-generated method stub
return iBookTypeInfoMapper.getBookTypeList();
}
}
service里面的接口也是和dao接口一样,这里就把service的接口写到一个java类里面了
IBookService文件:
public interface IBookService{
//增加图书信息
public boolean addBook(BookInfo bookInfo);
//删除图书信息
public boolean delBook(int id);
//修改图书信息
public boolean editBook(BookInfo bookInfo);
//获取图书列表
public List getAllBook();
//获取某本图书
public BookInfo getBook(int id);
//得到所有图书类型
public List getBookTypeList();
}
BookServiceImpl文件:
千万记得service注解要导入正确包。
import org.springframework.stereotype.Service;
@Service
public class BookServiceImpl implements IBookService {
@Autowired
private IBookInfoDao iBookInfoDao;
@Autowired
private IBookTypeInfoDao iBookTypeInfoDao;
@Override
public boolean addBook(BookInfo bookInfo) {
// TODO Auto-generated method stub
return iBookInfoDao.addBook(bookInfo);
}
@Override
public boolean delBook(int id) {
// TODO Auto-generated method stub
return iBookInfoDao.delBook(id);
}
@Override
public boolean editBook(BookInfo bookInfo) {
// TODO Auto-generated method stub
return iBookInfoDao.editBook(bookInfo);
}
@Override
public List getAllBook() {
// TODO Auto-generated method stub
return iBookInfoDao.getAllBook();
}
@Override
public BookInfo getBook(int id) {
// TODO Auto-generated method stub
return iBookInfoDao.getBook(id);
}
@Override
public List getBookTypeList() {
// TODO Auto-generated method stub
return iBookTypeInfoDao.getBookTypeList();
}
}
重要的一步mybatis、spring的配置文件
src下面创建一个config存放配置文件
mybatis.xml文件:
src根目录直接放spring配置文件beans.xml省的配置
beans.xml文件(一般要改的地方就数据库的datasource还有spring注解扫描的包):
oracle.jdbc.driver.OracleDriver
jdbc:oracle:thin:@localhost:1521:ORCLDB
scott
root
接下来就是测试了
写了那么久终于能测试下了555.
吐血,之前配置的BookMapper.xml里面的查找某本图书少了resultMap的声明,因为一次性写的所以找了挺久的.希望读到这篇文章的童鞋一定注意不要这样一口气在mapper里面写那么多方法,可以一个一个来,不然其中一个有问题所有的都不能运行.
放上我的测试类:
public class BookTest {
//测试新增图书信息
@Test
public void addBook(){
ApplicationContext ac =new ClassPathXmlApplicationContext("beans.xml");
IBookService bs = ac.getBean("bookService",IBookService.class);
BookInfo bi = new BookInfo();
bi.setAuthor("藤子不二雄3");
bi.setBookName("机器猫");
BookTypeInfo bti = new BookTypeInfo();
bti.setId(5);
bi.setBookTypeInfo(bti);
bi.setPrice(35.5);
try{
bs.addBook(bi);
System.out.println("ok");
}catch(Exception e ){
e.printStackTrace();
}
}
//测试更改图书信息
@Test
public void updateBook(){
ApplicationContext ac =new ClassPathXmlApplicationContext("beans.xml");
IBookService bs = ac.getBean("bookService",IBookService.class);
BookInfo bi = new BookInfo();
bi.setId(5);
bi.setAuthor("测试3");
bi.setBookName("机器猫");
BookTypeInfo bti = new BookTypeInfo();
bti.setId(5);
bi.setBookTypeInfo(bti);
bi.setPrice(35.5);
try{
bs.editBook(bi);
System.out.println("ok");
}catch(Exception e ){
e.printStackTrace();
}
}
//测试查询所有图书
@Test
public void selAllBook(){
ApplicationContext ac =new ClassPathXmlApplicationContext("beans.xml");
IBookService bs = ac.getBean("bookService",IBookService.class);
try{
List li =bs.getAllBook();
for(BookInfo bi:li){
System.out.println(bi.getAuthor()+" :"+bi.getBookName()+" "+bi.getBookTypeInfo().getBookTypeName());
}
}catch(Exception e){
e.printStackTrace();
}
}
//测试查找指定图书
@Test
public void getOneBook(){
ApplicationContext ac =new ClassPathXmlApplicationContext("beans.xml");
IBookService bs = ac.getBean("bookService",IBookService.class);
try{
BookInfo bi =null;
bi =bs.getBook(2);
if(bi!=null)
System.out.println(bi.getAuthor()+" :"+bi.getBookName());
else
System.out.println("kong ");
}catch(Exception e){
e.printStackTrace();
}
}
//测试删除特定图书
@Test
public void delBook(){
ApplicationContext ac =new ClassPathXmlApplicationContext("beans.xml");
IBookService bs = ac.getBean("bookService",IBookService.class);
try{
boolean flag =false;
flag =bs.deleteBook(5);
if(flag)
System.out.println("删除成功");
else
System.out.println("删除失败");
}catch(Exception e){
e.printStackTrace();
}
}
@Test
public void getAllType(){
ApplicationContext ac =new ClassPathXmlApplicationContext("beans.xml");
IBookService bs = ac.getBean("bookService",IBookService.class);
try{
List list = bs.getAllType();
for(BookTypeInfo bti :list){
System.out.println(bti.getId()+" :" +bti.getBookTypeName());
}
}catch(Exception e ){
e.printStackTrace();
}
}
}
接下来就准备到视图
配置spring、springMVC有关的web.xml##
org.springframework.web.context.ContextLoaderListener
contextConfigLocation
classpath*:beans.xml
org.springframework.web.util.IntrospectorCleanupListener
springMVC
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath*:config/spring-mvc.xml
1
springMVC
/
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encoding
utf-8
encodingFilter
/*
接下来写springMVC的配置文件
因为我在web.xml配置了文件名,文件路径,所以就不需要有配置文件的默认限制了.
在配置好的config里面配置spring-mvc.xml:
写对应的jsp页面
book_add.jsp:
新增图书
book_edit.jsp:
Insert title here
修改图书${book.bookTypeInfo.id }
book_list.jsp:
书名 作者 价格 类型 操作
${book.bookName}
${book.author}
${book.price}
${book.bookTypeInfo.bookTypeName}
编辑
删除
新增
failed_delete.jsp:
error
Delete Book Failed
springMVC的controller
src创建controller包,创建BookController
package controller;
import java.util.List;
import model.BookInfo;
import model.BookTypeInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;
import service.inter.IBookService;
@RequestMapping("book")
@Controller
public class BookController {
@Autowired
private IBookService bookService;
@RequestMapping("bookList")
/**
* 获取图书列表并转到页面
* @return
*/
public ModelAndView showList(){
List li = null;
try{
li =bookService.getAllBook();
}catch(Exception e){
e.printStackTrace();
}
return new ModelAndView("book_list","list",li);
}
@RequestMapping("toaddBook")
/**
* 获取所有图书类型并转到页面
* @return
*/
public ModelAndView toAddBookView(){
List li=null;
try{
li =bookService.getBookTypeList();
}catch(Exception e){
e.printStackTrace();
}
return new ModelAndView("book_add","list" ,li);
}
@RequestMapping("addBook")
/**
* 图书新增
* @param bi
* @return
*/
public String toAddBookView(BookInfo bi){
try{
System.out.println(bi.getBookName());
bookService.addBook(bi);
}catch(Exception e){
e.printStackTrace();
}
return "redirect:bookList";
}
@RequestMapping("toEditBook")
/**
* 这个方法用来把图书对象加入到request然后转到toEdit
* @param id
* @param redirectAttributes
* @return
*/
public String toEditBook(int id ,RedirectAttributes redirectAttributes){
BookInfo bi =bookService.getBook(id);
//相当于在这次的request里面加一个属性
redirectAttributes.addFlashAttribute("book",bi);
return "redirect:toEdit";
}
@RequestMapping("toEdit")
/**
* 获取图书类型然后转到book_edit页面
* @return
*/
public ModelAndView toEditBook(){
List li=null;
try{
li =bookService.getBookTypeList();
}catch(Exception e){
e.printStackTrace();
}
return new ModelAndView("book_edit","list" ,li);
}
@RequestMapping("editBook")
@ResponseBody
/**
* 修改方法
* @param book
* @return
*/
public String editBook(BookInfo book){
try{
bookService.editBook(book);
return "succeed";
}catch(Exception e){
e.printStackTrace();
}
return "falied";
}
@RequestMapping("delBook")
/**
* 删除方法
* @param id
* @return
*/
public String delBook(int id){
boolean flag=false;
try{
bookService.delBook(id);
flag = true;
}catch(Exception e){
e.printStackTrace();
}
if(flag){
return "redirect:bookList";
}else{
return "failed_delete";
}
}
}
最后把我的包和类都截图下
整合到这完毕.功能测试成功!哈哈.不过码代码累啊,第一次写整合帖,还出错了.不过经验也学到了,希望能给需要的童鞋一点启发.整个项目我会发上来.给需要的人.
