spring+springmvc+hibernate整合实例-阿里云开发者社区

最近要弄一个自动化生成表及其实体对应的增删改查的框架，于是我想到了hibernate,hibernate就有根据实体自动建表，而且增删改查，都不需要想mybatis那样在xml文件中配置。

不过怎样让该框架通过前端一个表单页面配置，从而让后台对应的生成，这个我还没想明白，不过说到这，不得不提传统的ssh框架，传统的ssh框架，通常是指spring+struts2+hibernate或spring+struts+hibernate

不过想到struts2就有恐惧感，太多的action和xml配置，比较繁琐,不如springmvc来的痛快。所以我想这也许是struts2现在用的人数不如springmvc多的原因之一。当然，也不能说struts2就不好了，据说struts2（struts）+spring+hibernate称之为最经典的mvc框架。

说到MVC,M指的是模型，V指的是视图，C值的控制器，通俗的理解，可以这么说，视图通过控制器的到模型(数据），这让我想到了JSP+Servlet+JDBC。jsp负责展示数据，servet处理前端请求，与jdbc交互，将数据返回给jsp。

目前MVC在互联网用的比较广。

不多说了，来一波整合吧。好久没整这个都忘记了，写一个作纪念，同时万一以后业务需要，省的去找，同时也给大家学习借鉴使用

一、准备环境

JDK8 Maven tomcat7(tomcat8)都行 mysql5.5以上

二、pom文件

            </plugin>



        </plugins>
        <finalName>${project.artifactId}</finalName>
    </build>

</project>

三、建立实体和DAO

package com.ssh.entity;

import lombok.Data;

import javax.persistence.*;

/**
 * Created by XRog
 * On 2/2/2017.2:03 PM
 */
@Data
@Entity
@Table(name = "Person")
public class Person {

    @Id
    @GeneratedValue
    private Long id;

    @Column(name = "created")
    private Long created = System.currentTimeMillis();

    @Column(name = "username")
    private String username;

    @Column(name = "address")
    private String address;

    @Column(name = "phone")
    private String phone;

    @Column(name = "remark")
    private String remark;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public Long getCreated() {
        return created;
    }

    public void setCreated(Long created) {
        this.created = created;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }
    
    
}

package com.ssh.repository;

import java.io.Serializable;
import java.util.List;

/**
 * Created by XRog
 * On 2/2/2017.2:28 PM
 */
public interface DomainRepository<T,PK extends Serializable>{
    T load(PK id);

    T get(PK id);

    List<T> findAll();

    void persist(T entity);

    PK save(T entity);

    void saveOrUpdate(T entity);

    void delete(PK id);

    void flush();
}

package com.ssh.repository;

import com.ssh.entity.Person;

/**
 * Created by XRog
 * On 2/2/2017.2:25 PM
 */
public interface PersonRepository extends DomainRepository<Person,Long> {
}

三、建立业务接口及其实现类

package com.ssh.service;

import com.ssh.entity.Person;

/**
 * Created by XRog
 * On 2/2/2017.2:39 PM
 */
public interface PersonService {
    Long savePerson();
    
    Person getId(Long id);
    
    void delete(Long id);
}

package com.ssh.repository.impl;

import java.util.List;

import javax.persistence.Query;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.ssh.entity.Person;
import com.ssh.repository.PersonRepository;

/**
 * Created by XRog
 * On 2/2/2017.2:30 PM
 */
@Repository
public class PersonRepositoryImpl implements PersonRepository {

    @Autowired
    private SessionFactory sessionFactory;

    private Session getCurrentSession() {
        return this.sessionFactory.openSession();
    }

    public Person load(Long id) {
        return (Person)getCurrentSession().load(Person.class,id);
    }

    public Person get(Long id) {
        return (Person)getCurrentSession().get(Person.class,id);
    }

    public List<Person> findAll() {
       Query query = getCurrentSession().createQuery("select * from user");
        return query.getResultList();
    }

    public void persist(Person entity) {
        getCurrentSession().persist(entity);
    }

    public Long save(Person entity) {
        return (Long)getCurrentSession().save(entity);
    }

    public void saveOrUpdate(Person entity) {
        getCurrentSession().saveOrUpdate(entity);
    }

    public void delete(Long id) {
        Person person = load(id);
        getCurrentSession().delete(person);
    }

    public void flush() {
        getCurrentSession().flush();
    }
}

四、ssh框架相关的xml和properties配置

applicationContext.xml配置如下:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

    <!--********************************************配置Spring***************************************-->
        <!-- 自动扫描 -->
        <context:component-scan base-package="com.ssh">
            <!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
            <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>


    <!--********************************************配置hibernate********************************************-->

    <!--扫描配置文件(这里指向的是之前配置的那个config.properties)-->
    <context:property-placeholder location="classpath:/config.properties" />

    <!--配置数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${jdbc.driver}" />  <!--数据库连接驱动-->
        <property name="jdbcUrl" value="${jdbc.url}" />     <!--数据库地址-->
        <property name="user" value="${jdbc.username}" />   <!--用户名-->
        <property name="password" value="${jdbc.password}" />   <!--密码-->
        <property name="maxPoolSize" value="40" />      <!--最大连接数-->
        <property name="minPoolSize" value="1" />       <!--最小连接数-->
        <property name="initialPoolSize" value="10" />      <!--初始化连接池内的数据库连接-->
        <property name="maxIdleTime" value="20" />  <!--最大空闲时间-->
    </bean>

    <!--配置session工厂-->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="packagesToScan" value="com.ssh.entity" />
        <property name="hibernateProperties">
            <props>
                
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <!--hibernate根据实体自动生成数据库表-->
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>   <!--指定数据库方言-->
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>     <!--在控制台显示执行的数据库操作语句-->
                <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>     <!--在控制台显示执行的数据哭操作语句（格式）-->
      
            </props>
        </property>
          
    </bean>

    <!-- 事物管理器配置  -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

</beans>

config.properties文件如下:

#database connection config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/ssh?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = 1234

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.show_sql = true
hibernate.format_sql = true
hibernate.hbm2ddl.auto = update

spring-mvc.xml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"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:task="http://www.springframework.org/schema/task"  
    xsi:schemaLocation="http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/task  
        http://www.springframework.org/schema/task/spring-task-3.1.xsd" >

    <!-- 扫描Controller层 -->
    <context:component-scan base-package="com.ssh.controller"/>
    
    <mvc:default-servlet-handler/>
    
    <!-- 开启注解 -->
    <mvc:annotation-driven />
    
    
    <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/" />
        <property name="suffix" value=".jsp" /><!--可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑 -->
    </bean>

     
</beans>

五、Controller

package com.ssh.controller;

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.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.ssh.entity.User;
import com.ssh.service.PersonService;
import com.ssh.service.UserService;


/**
 * Created by XRog
 * On 2/1/2017.12:36 AM
 */
@Controller
public class MainController {

    @Autowired
    private PersonService personService;

    @Autowired
    private UserService userService;
    
    @RequestMapping(value = "savePerson", method = RequestMethod.GET)
    @ResponseBody
    public String savePerson(){
       return "success";
    }
}

六、数据表

/*
SQLyog Ultimate v8.32 
MySQL - 5.7.20-log : Database - ssh
*********************************************************************
*/


/*!40101 SET NAMES utf8 */;

/*!40101 SET SQL_MODE=''*/;

/*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */;
/*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */;
/*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */;
/*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */;
CREATE DATABASE /*!32312 IF NOT EXISTS*/`ssh` /*!40100 DEFAULT CHARACTER SET utf8 */;

USE `ssh`;

/*Table structure for table `person` */

DROP TABLE IF EXISTS `person`;

CREATE TABLE `person` (
  `id` bigint(20) NOT NULL,
  `address` varchar(255) DEFAULT NULL,
  `created` bigint(20) DEFAULT NULL,
  `phone` varchar(255) DEFAULT NULL,
  `remark` varchar(255) DEFAULT NULL,
  `username` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

/*Data for the table `person` */

insert  into `person`(`id`,`address`,`created`,`phone`,`remark`,`username`) values (1,'1',1,'1','1','1');

/*!40101 SET SQL_MODE=@OLD_SQL_MODE */;
/*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */;
/*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */;
/*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;

七、配置web.xml文件

<?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"
         version="3.0">
        <!-- 地址为http://localhost:8080/  显示的默认网页-->
        <welcome-file-list>
          <welcome-file>/index.jsp</welcome-file>
        </welcome-file-list>

    <!--加载Spring的配置文件到上下文中去-->
