【SpringMVC】三大框架整合纯java版

首先引入三大框架所用jar包

结构如下:

准备数据库连接所需配置jdbc.properties

jdbc.user=rootjdbc.password=aini1314jdbc.driverClass=com.mysql.jdbc.Driverjdbc.jdbcUrl=jdbc:mysql:///springmvc

以及hibernate所需配置hibernate.properties

hibernate.dialect=org.hibernate.dialect.MySQL5Dialecthibernate.hbm2ddl.auto=update

在web.xml中进行Spring的配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"><!-- 配置SpringMVC --> <servlet>  <servlet-name>dispatcherServlet</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <init-param><!-- 用哪种容器类 -->  <param-name>contextClass</param-name>  <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>  </init-param>  <init-param><!-- 入口配置 -->  <param-name>contextConfigLocation</param-name>  <param-value>cn.qblank.AppConfig</param-value>  </init-param>  </servlet>  <servlet-mapping>  <servlet-name>dispatcherServlet</servlet-name>  <url-pattern>/</url-pattern>  </servlet-mapping></web-app>

在AppConfig类代替xml进行hibernate的配置

package cn.qblank;import javax.sql.DataSource;import org.hibernate.SessionFactory;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.PropertySource;import org.springframework.core.env.Environment;import org.springframework.jdbc.datasource.DriverManagerDataSource;import org.springframework.orm.hibernate5.HibernateTransactionManager;import org.springframework.orm.hibernate5.LocalSessionFactoryBean;import org.springframework.transaction.PlatformTransactionManager;import org.springframework.transaction.annotation.EnableTransactionManagement;import org.springframework.web.servlet.ViewResolver;import org.springframework.web.servlet.config.annotation.EnableWebMvc;import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;import org.springframework.web.servlet.view.InternalResourceViewResolver;import org.springframework.web.servlet.view.JstlView;@Configuration@ComponentScan("cn.qblank")@PropertySource("classpath:jdbc.properties") //引入外部属性文件到Enviroment@EnableTransactionManagement@EnableWebMvcpublic class AppConfig extends WebMvcConfigurerAdapter{/** * 负责将控制器方法返回的字符串映射到某个JSP */@Beanpublic ViewResolver viewResolver(){//创建对象InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();// 支持jsp及标准taglibviewResolver.setViewClass(JstlView.class);//设置前后缀viewResolver.setPrefix("/WEB-INF/jsp/");viewResolver.setSuffix(".jsp");return viewResolver;}/** * 扫描实体类 */@Beanpublic LocalSessionFactoryBean sessionFactory(DataSource dataSource){LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();//加载数据源factoryBean.setDataSource(dataSource);//自动扫描实体类factoryBean.setPackagesToScan("cn.qblank.entity");return factoryBean;}/** * 配置数据源 * 依赖Environment */@Beanpublic DataSource dataSource(Environment env){DriverManagerDataSource ds = new DriverManagerDataSource();ds.setDriverClassName(env.getProperty("jdbc.driverClass"));ds.setUrl(env.getProperty("jdbc.jdbcUrl"));ds.setUsername(env.getProperty("jdbc.user"));ds.setPassword(env.getProperty("jdbc.password"));return ds;}/** * 创建事务类 * @param sessionFactory * @return */@Beanpublic PlatformTransactionManager transactionManager(SessionFactory sessionFactory){HibernateTransactionManager transactionManager = new HibernateTransactionManager();transactionManager.setSessionFactory(sessionFactory);return transactionManager;}/** * bootstrap映射路径 */@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {registry.addResourceHandler("/assets/**").addResourceLocations("/public/");}}

书写dao层接口

package cn.qblank.dao;import java.util.List;import org.springframework.stereotype.Repository;import org.springframework.transaction.annotation.Transactional;import cn.qblank.entity.Book;public interface IBookDao {/** * 查询所有 * @return */List<Book> findAll();/** * 添加图书 */void addBook(Book book);/** * 修改图书 */void updateBook(Book book);/** * 删除图书 */void deleteBook(Long id);/** * 通过id查找 */Book findById(long id);}

实现类BookDaoImpl

package cn.qblank.dao.impl;import java.util.List;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;import org.springframework.transaction.annotation.Transactional;import cn.qblank.dao.IBookDao;import cn.qblank.entity.Book;@Repository@Transactionalpublic class BookDaoImpl implements IBookDao{@Autowiredprivate SessionFactory sessionFactory;@SuppressWarnings("unchecked")@Overridepublic List<Book> findAll() {return sessionFactory.getCurrentSession().createQuery("from Book").list();}@Overridepublic void addBook(Book book) {Session session = sessionFactory.getCurrentSession();session.save(book);}@Overridepublic void updateBook(Book book) {sessionFactory.getCurrentSession().update(book);}@Overridepublic void deleteBook(Long id) {Session session = sessionFactory.getCurrentSession();//通过id查询到对象Book book = session.get(Book.class, id);session.delete(book);}@Overridepublic Book findById(long id) {return sessionFactory.getCurrentSession().get(Book.class, id);}}

同样的实现service层接口

package cn.qblank.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import cn.qblank.dao.IBookDao;import cn.qblank.entity.Book;import cn.qblank.service.IBookService;@Service@Transactionalpublic class BookServiceImpl implements IBookService{@Autowiredprivate IBookDao bookDao;@Overridepublic List<Book> findAll() {return bookDao.findAll();}@Overridepublic void addBook(Book book) {bookDao.addBook(book);}@Overridepublic void updateBook(Book book) {System.out.println("service:" + book);bookDao.updateBook(book);}@Overridepublic void deleteBook(Long id) {bookDao.deleteBook(id);}@Overridepublic Book findById(Long id) {return bookDao.findById(id);}}

书写控制类BookController

package cn.qblank.control;import java.util.List;import javax.validation.Valid;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.validation.BindingResult;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import cn.qblank.entity.Book;import cn.qblank.service.IBookService;@Controller  //控制器注解public class BookController {@Autowiredprivate IBookService bookService;@RequestMapping(method = RequestMethod.POST, value = "/add")public String add(@ModelAttribute @Valid Book book,BindingResult bindingResult){//调用业务//添加图书bookService.addBook(book);if (bindingResult.hasErrors()) {return "add";}//跳转return "redirect:/list";}/** * 展示图书列表 * @param model * @return */@RequestMapping(method = RequestMethod.GET, value = "/list")public String list(Model model){//调用service处理业务List<Book> books = bookService.findAll();//存入model中model.addAttribute("books", books);return "list";}/** * 删除功能 * @param book * @return */@RequestMapping(value = "/delete")public String delete(@ModelAttribute Book book){bookService.deleteBook(book.getId());return "redirect:/list";}/** * 跳转到修改页面 * @param model * @param book * @return */@RequestMapping(value = "/update/{id}")public String update(@PathVariable long id,Model model){Book book = bookService.findById(id);System.out.println(book);model.addAttribute("book",book);return "update";}/** * 跳转到主页 */@RequestMapping(value = "/updateJsp")public String updateJsp(Model model,@Valid Book book, BindingResult bindingResult){//if (bindingResult)book = bookService.findById(book.getId());//进行修改操作bookService.updateBook(book);return "redirect:/list";}/** * 跳转到jsp页面 * @return */@RequestMapping(method = RequestMethod.GET , value = "/addJsp")public String addJsp(@ModelAttribute @Valid Book book,BindingResult bindingResult){return "add";}}
