• Spring + Spring MVC + Hibernate项目开发集成(注解)


      在自己从事的项目中都是使用xml配置的方式来进行的,随着项目的越来越大,会发现配置文件会相当的庞大,这个不利于项目的进行和后期的维护。于是考虑使用注解的方式来进行项目的开发,前些日子就抽空学习了一下。在网上也查询了很多使用注解来搭建开发框架的文章,但是有一个问题就是,使用更新的软件版本会出错。这里我将使用最新的Spring,Hibernate来进行框架的搭建,经过测试,顺利运行。分享旨在与大家一起分享学习,共同进步,有不足之处,望不吝赐教,谢谢!

      本项目使用maven构建,采用Spring + Spring MVC + Hibernate + MySQL进行搭建,下面简要说明本项目所使用软件版本:

         maven:3.2.3
         hibernate:4.3.9.Final
         spring:4.1.6.RELEASE
         mysql:5.1.35

      接下来我看一下项目的整体结构:

      

         

    下面我们开始框架的搭建之旅吧。

    一,配置文件

    1,首先配置pom.xml,获得项目所需要的jar文件。

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    38     <mvc:annotation-driven/>
    39     
    40 </beans>

    3,配置web.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

          <welcome-file>default.jsp</welcome-file>
        </welcome-file-list>
    </web-app>

    4,配置Spring,在classpath路径下新建applicationContext.xml文件,配置如下:

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"
            default-autowire="byName" default-lazy-init="true">
        <context:component-scan base-package="cn.mylife"/>
            
        <context:property-placeholder location="classpath:hibernate.properties"/>
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">

        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
            <property name="hibernateProperties">  
                <props>  
                    <prop key="hibernate.dialect">${hibernate.dialect}</prop>  
                    <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>  
                    <prop key="hibernate.cache.provider_class">${hibernate.cache.provider_class}</prop>  
                    <prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop>  
                    <prop key="hibernate.jdbc.batch_size">${hibernate.jdbc.batch_size}</prop>  
                    <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop>  
                    <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>  
                    <!-- 这一个必须配置,否则会出现no session 的错误 -->
                    <!-- <prop key="hibernate.current_session_context_class">${hibernate.current_session_context_class}</prop> -->
                </props>  
            </property>
            <!-- 自动扫描制定位置下的实体进行映射  --> 
            <property name="packagesToScan" value="cn.mylife.entity"/>
        </bean>
        
        <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
            <property name="sessionFactory" ref="sessionFactory" />
        </bean>
        <tx:annotation-driven transaction-manager="transactionManager"/>
    </beans>

    二,代码实现

    1,创建entity实体类:cn.mylife.entity.User

    package cn.mylife.entity;
    
    import java.io.Serializable;
    
    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.GenerationType;
    import javax.persistence.Id;
    import javax.persistence.Table;
    
    /**
     * 用户User实体类
     * @author Xiongyan
     * @date 2015年5月6日 上午10:24:24
     * @version 0.0.1
     */
    @SuppressWarnings("serial")
    @Entity
    @Table(name="tb_user")
    public class User implements Serializable {
        @Id
        @GeneratedValue(strategy=GenerationType.AUTO)
        private Integer id;
        
        @Column(name="user_name", length=50, nullable=false)
        private String name;
    
        public Integer getId() {
            return id;
        }
    
        public void setId(Integer id) {
            this.id = id;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
    }

    2,实现dao层基类:cn.mylife.dao.BaseDao<T>

    package cn.mylife.dao;
    
    import java.io.Serializable;
    import java.util.List;
    
    import javax.annotation.Resource;
    
    import org.hibernate.SessionFactory;
    import org.springframework.stereotype.Repository;
    
    /**

     * 
     * @author Xiongyan

     */
    @Repository
    public class BaseDao<T> {
        @Resource
        private SessionFactory sessionFactory;

         */
        public void save(T t) {
            sessionFactory.getCurrentSession().save(t);
        }
    
        /**

         */
        public void delete(Serializable id, Class<T> clazz) {
            T t = get(id, clazz);
            if (t != null)
                sessionFactory.getCurrentSession().delete(t);
            else
                new RuntimeException("你要删除的数据不存在").printStackTrace();
            ;
        }
    
        /**

         */
        public void update(T t) {
            sessionFactory.getCurrentSession().update(t);
        }
    
        /**

         * 
         * @author Xiongyan
         * @date 2015年5月6日 下午5:29:46
         * @throws
         * @return T 返回类型
         */
        @SuppressWarnings("unchecked")
        public T get(Serializable id, Class<T> clazz) {
            return (T) sessionFactory.getCurrentSession().get(clazz, id);
        }
    
        /**
         * 查找所有数据
         *

         * @throws
         * @return List<T> 返回类型
         */
        @SuppressWarnings("unchecked")
        public List<T> getAll(Class<T> clazz) {
            return sessionFactory.getCurrentSession().createQuery(clazz.toString()).list();
        }
    }

    3,service层代码的实现

    package cn.mylife.service.user;
    
    import java.io.Serializable;
    import java.util.List;
    
    import javax.transaction.Transactional;

         */
        public List<T> getAll();
    }
    package cn.mylife.service.user.impl;
    
    import java.io.Serializable;

    }
    package cn.mylife.service.user;
    
    import cn.mylife.entity.User;
    
    public interface UserService extends BaseService<User>{
        
    }
    package cn.mylife.service.user.impl;
    
    import org.springframework.stereotype.Service;
    
    import cn.mylife.entity.User;
    import cn.mylife.service.user.UserService;
    
    @Service
    public class UserServiceImpl extends BaseServiceImpl<User> implements UserService{
        
    }

    4,controller层代码的实现

    package cn.mylife.controller;
    
    import org.springframework.context.annotation.Scope;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    @Controller
    @RequestMapping("/user")
    @Scope("prototype")
    public class UserController {
    
        @RequestMapping(value = "/save")
        public ModelAndView saveUser() {
            ModelAndView view = new ModelAndView("/jsps/testPage");
            System.out.println("-- 访问成功 --");
            return view;
        }
    
    }

    5,编写JSP页面

    <%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>测试页面</title>
    </head>
    <body>
    这只是一个测试页面。
    </body>
    </html>

    6,编写Spring测试代码:cn.mylife.junit.SpringJunit4.java

    package cn.mylife.junit;
    
    import javax.annotation.Resource;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    import cn.mylife.entity.User;
    import cn.mylife.service.user.UserService;
    
    @RunWith(SpringJUnit4ClassRunner.class)
    // 加载spring配置文件
    @ContextConfiguration(locations = { "classpath:applicationContext.xml" })
    public class SpringJunit4 {
        @Resource
        private UserService userService;
    
        @Test
        public void testUser() throws Exception {
            User user = new User();
            user.setName("中国人名共和国");
            userService.save(user);
        }
    }

    7,运行测试

    我们的测试代码运行成功,下面我们看一下数据库

    8,接下来我们测试一下Spring MVC。在浏览器中输入:http://localhost/mylife/user/save.do

    至此,咱们的开发框架搭建完成,本文还有很多不足和需要完善的地方,望指出,谢谢!
