spring+springmvc+hibernate整合实例

2022-11-14 14:53:19

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-->

        <context-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>

                classpath:applicationContext.xml

            </param-value>

        </context-param>
