好的,下面是基于SSH框架连接数据库实现图书信息管理系统的代码框架,仅供参考。
1. 数据库连接配置文件 applicationContext.xml
```xml
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/bookstore" />
<property name="username" value="root" />
<property name="password" value="123456" />
</bean>
```
2. 图书信息实体类 Book.java
```java
public class Book {
private Integer id;
private String name;
private String author;
private String press;
private Date publishDate;
// getter/setter 略
}
```
3. DAO接口 BookDao.java
```java
public interface BookDao {
void save(Book book);
void update(Book book);
void delete(Integer id);
Book findById(Integer id);
List<Book> findAll();
}
```
4. DAO实现类 BookDaoImpl.java
```java
public class BookDaoImpl extends HibernateDaoSupport implements BookDao {
@Override
public void save(Book book) {
getHibernateTemplate().save(book);
}
@Override
public void update(Book book) {
getHibernateTemplate().update(book);
}
@Override
public void delete(Integer id) {
getHibernateTemplate().delete(findById(id));
}
@Override
public Book findById(Integer id) {
return getHibernateTemplate().get(Book.class, id);
}
@Override
public List<Book> findAll() {
return (List<Book>) getHibernateTemplate().find("from Book");
}
}
```
5. Service层 BookService.java
```java
public interface BookService {
void add(Book book);
void update(Book book);
void delete(Integer id);
Book findById(Integer id);
List<Book> findAll();
}
```
6. Service实现类 BookServiceImpl.java
```java
public class BookServiceImpl implements BookService {
private BookDao bookDao;
public void setBookDao(BookDao bookDao) {
this.bookDao = bookDao;
}
@Override
public void add(Book book) {
bookDao.save(book);
}
@Override
public void update(Book book) {
bookDao.update(book);
}
@Override
public void delete(Integer id) {
bookDao.delete(id);
}
@Override
public Book findById(Integer id) {
return bookDao.findById(id);
}
@Override
public List<Book> findAll() {
return bookDao.findAll();
}
}
```
7. 控制器 BookController.java
```java
@Controller
@RequestMapping("/book")
public class BookController {
@Autowired
private BookService bookService;
@RequestMapping("/list")
public String list(Model model) {
List<Book> bookList = bookService.findAll();
model.addAttribute("bookList", bookList);
return "book/list";
}
@RequestMapping("/add")
public String add(Book book) {
bookService.add(book);
return "redirect:/book/list";
}
@RequestMapping("/delete/{id}")
public String delete(@PathVariable Integer id) {
bookService.delete(id);
return "redirect:/book/list";
}
@RequestMapping("/edit/{id}")
public String edit(@PathVariable Integer id, Model model) {
Book book = bookService.findById(id);
model.addAttribute("book", book);
return "book/edit";
}
@RequestMapping("/update")
public String update(Book book) {
bookService.update(book);
return "redirect:/book/list";
}
}
```
以上是基于SSH框架连接数据库实现图书信息管理系统的代码框架,具体实现过程中还需要进行一些改进和完善。
