Springmvc 配置(spring+hibernate+springmvc）
新建web项目
导入jar 包
以上包再加上spring的所有jar包
目录结构如下：
建立包
entity ，dao, manager，web,
Spring 的配置文件全部放在config/spring目录下，包括数据库配置,这里将不再使用hibernate.cfg.xml进行配置，而是将其放在
spring-common.xml 里边。
我们将要配置的xml文件如下：
Web.Xml配置
<!-- 配置字符集 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 加载所有的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/spring/spring-*.xml</param-value>
</context-param>
<!-- 配置Spring监听 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置SpringMVC -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/spring/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
spring-mvc.xml配置
<!-- 注解扫描包 -->
<context:component-scanbase-package="com"/>
<!-- 开启注解 -->
<mvc:annotation-driven/>
<!-- 静态资源(js/image)的访问 -->
<mvc:resourceslocation="/js/"mapping="/js/**"/>
<mvc:resourceslocation="/image/"mapping="/image/**"/>
<!-- 定义视图解析器 -->
<beanid="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<propertyname="prefix"value="/jsp/"></property>
<propertyname="suffix"value=".jsp"></property>
</bean>
spring-common.xml配置
<!-- 配置数据源 -->
<beanid="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource">

</property>
</bean>

后台代码：
例子：Book增删改查的基本操作
Book.java（实体类）（jpa自动生成代码，这里的主键ID使用的是uuid）
package com.test.entity;
import java.io.Serializable;
import javax.persistence.*;
importorg.hibernate.annotations.GenericGenerator;
/**
*The persistent class for the book database table.
*
*/
@Entity
@Table(name="book")
public class Book implements Serializable {
privatestatic final long serialVersionUID = 1L;
@Id
@GeneratedValue(generator="system-uuid")
@GenericGenerator(name ="system-uuid",strategy="uuid")
@Column
privateint id;
@Column
private String auther;
@Column
private String bookname;
@Column
private String isbn;
@Column
private int price;
@Column
private int stock;
publicBook() {
}
publicint getId() {
returnthis.id;
}
publicvoid setId(int id) {
this.id= id;
}
publicString getAuther() {
returnthis.auther;
}
publicvoid setAuther(String auther) {
this.auther= auther;
}
publicString getBookname() {
returnthis.bookname;
}
publicvoid setBookname(String bookname) {
this.bookname= bookname;
}
publicString getIsbn() {
returnthis.isbn;
}
publicvoid setIsbn(String isbn) {
this.isbn= isbn;
}
publicint getPrice() {
returnthis.price;
}
publicvoid setPrice(int price) {
this.price= price;
}
publicint getStock() {
returnthis.stock;
}
publicvoid setStock(int stock) {
this.stock= stock;
}
}
Service的代码：
BookDao
package com.test.dao;
import java.util.List;
import com.test.entity.Book;
public interface BookDao {
public Book getBook(String id);
public List<Book> getAllBook();
public void addBook(Book book);
public boolean delBook(String id);
public booleanupdateBook(Book book);
}
BookDaoImpl
package com.test.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
import com.test.entity.Book;
public class BookDaoImpl implements BookDao {
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@Override
publicBook getBook(String id) {
//TODO Auto-generated method stub
String hql = "from book u where u.id=?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, id);
return (Book)query.uniqueResult();
}
@Override
publicList<Book> getAllBook() {
//TODO Auto-generated method stub
String hql = "from book";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
return query.list();
}
@Override
publicvoid addBook(Book book) {
//TODO Auto-generated method stub
sessionFactory.getCurrentSession().save(book);
}
@Override
publicboolean delBook(String id) {
//TODO Auto-generated method stub
String hql = "delete book u where u.id = ?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, id);
return (query.executeUpdate() > 0);
}
@Override
publicboolean updateBook(Book book) {
//TODO Auto-generated method stub
String hql = "update book u set u.bookname = ?,u.isbn=?,u.price=?,u.stock=?where u.id = ?";
Query query = sessionFactory.getCurrentSession().createQuery(hql);
query.setString(0, book.getAuther());
query.setString(1, book.getBookname());
query.setString(2, book.getIsbn());
query.setInteger(3, book.getPrice());
query.setInteger(4, book.getStock());
return (query.executeUpdate() > 0);
}
}
BookManager
package com.test.manager;
import java.util.List;
import com.test.entity.Book;
public interface BookManager {
public Book getBook(String id);
public List<Book> getAllBook();
public void addBook(Book book);
public boolean delBookr(String id);
public boolean updateBook(Book book);
}
BookManagerImpl
package com.test.manager;
import java.util.List;
import com.test.dao.BookDao;
import com.test.entity.Book;
public class BookManagerImpl implementsBookManager {
privateBookDao bookDao;
publicvoid setBookDao(BookDao bookDao) {
this.bookDao= bookDao;
}
@Override
publicBook getBook(String id) {
//TODO Auto-generated method stub
returnbookDao.getBook(id);
}
@Override
publicList<Book> getAllBook() {
//TODO Auto-generated method stub
returnbookDao.getAllBook();
}
@Override
publicvoid addBook(Book book) {
//TODO Auto-generated method stub
bookDao.addBook(book);
}
@Override
publicboolean delBookr(String id) {
//TODO Auto-generated method stub
returnbookDao.delBook(id);
}
@Override
publicboolean updateBook(Book book) {
//TODO Auto-generated method stub
returnbookDao.updateBook(book);
}
}
control的代码：
控制器后面在补充：
接下来是将bookDao注入
spring-beans.xml
<beanid="bookDao"class="com.test.dao.BookDaoImpl">
<propertyname="sessionFactory"ref="sessionFactory"></property>
</bean>
<beanid="bookManagerBase"class="com.test.manager.BookManagerImpl">
<propertyname="bookDao"ref="bookDao"></property>
</bean>
<!-- 此处为代理 -->
<beanname="bookManager"parent="transactionProxy">
<propertyname="target"ref="bookManagerBase"></property>
</bean>
启动项目没有报错则说名配置没问题，数据库的连接以及bean注入等都没问题，接下来可以测试一下是否正确。
