淺析hibnate+spring mvc

  除了hibnate+  spring mvc模式，還有PHP mvc ，asp.net mvc模式，他們均可以搭建不一樣的框架。

  只不過平臺不一樣，一種Java平臺，能夠到java.com網站下載。能夠開發javaweb,javabean,一種net平臺。數據庫不一樣，asp.net使用sql,spring mvc可以使用MySQL

oracle。

  

開發框架搭建

建立工程

         在Eclipse的Java EE版本或MyEclipse中建立一個Dynamic Web Project。並建立以下包：

（1）com.dao：系統的DAO；

（2）com.model：表的實體類（使用Hibernate），在該工程中不配置.hbm.xml映射文件，採起註解的方式；

（3）com.service：業務邏輯接口類和實現類；

（4）com.web：Spring MVC的Controllor類；

（5）com.config：Spring和Spring MVC的配置文件。

建立成功後包結構以下所示：
   springmvctest
        src 
        ----com
            ----amigo
                ----dao
                ----model
                ----service
                ----web
         ----config
         WebContent
         ----META-INF
         ----WEB-INF
             ----lib
             ----classes

 引入相關包

         須要將Spring、Spring MVC、Hibernate、MySQL驅動、log4j、c3p0數據源等的相關包引入。lib目錄下的jar包以下：

 配置文件 配置web.xml

         在web.xml中須要配置Spring的配置文件（applicationContext.xml）和Spring MVC配置文件（spring-mvc.xml），配置指定全部.do的請求都由Spring的DispatcherServlet類進行處理。

web.xml文件的參考配置以下：

<? xml version = " 1.0 "  encoding = " UTF-8 " ?>

配置 spring 的配置文件

 

         Spring的配置文件applicationContext.xml文件中主要配置對Hibernate的事務的管理，該配置文件的參考配置以下：

<? xml version = " 1.0 "  encoding = " UTF-8 " ?>

  配置 Spring MVC 配置文件

 

Spring MVC的配置文件spring-mvc.xml中主要是Controller的配置信息，該文件的參考配置以下：

<? 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:p ="http://www.springframework.org/schema/p"
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-3.0.xsd 
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"    
    default-lazy-init ="true" >
     < context:annotation-config  />
     <!-- 使Spring支持自動檢測組件，如註解的Controller  -->
     < context:component-scan  base-package ="com.amigo.web" />

     < bean  id ="viewResolver"       class ="org.springframework.web.servlet.view.InternalResourceViewResolver"
          p:prefix ="/WEB-INF"
          p:suffix =".jsp"   />
    
     < bean  class ="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"   />
     <!--  啓動 Spring MVC 的註解功能，完成請求和註解 POJO 的映射  -->
     < bean      class ="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >
         < property  name ="messageConverters" >
             < list >
                 < bean  class ="org.springframework.http.converter.StringHttpMessageConverter" >  
                 </ bean >
             </ list >
         </ property >
     </ bean >
</ beans >

 

 建立數據庫和表

建立test數據庫和user_info表的SQL語句以下（爲了簡便，user_info只有一個USER_NAME字段）：

CREATE   DATABASE  test;
USER  test;
CREATE   TABLE  user_info (
  USER_NAME   varchar ( 32 )  NOT   NULL ,
  PRIMARY   KEY  ( USER_NAME )
) ENGINE = InnoDB  DEFAULT  CHARSET = utf8;

3、實例代碼

3.1 DAO層

BaseHibernateDao類的代碼以下所示：

package  com.amigo.dao;

import  javax.annotation.Resource;

import  org.hibernate.HibernateException;
import  org.hibernate.Session;
import  org.hibernate.SessionFactory;
import  org.springframework.dao.DataAccessException;
import  org.springframework.dao.DataAccessResourceFailureException;
import  org.springframework.dao.support.DaoSupport;
import  org.springframework.orm.hibernate3.HibernateTemplate;
import  org.springframework.orm.hibernate3.SessionFactoryUtils;

public   class  BaseHibernateDao  extends  DaoSupport {
    private SessionFactory sessionFactory;
    private HibernateTemplate hibernateTemplate;
    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    @Resource(name="sessionFactory")
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
        this.hibernateTemplate=createHibernateTemplate(sessionFactory);
    }

    public Session getSession() {
        if (this.sessionFactory == null) {
            throw new HibernateException("Session Create Fail,SessionFactory is null!");
        }
        return this.sessionFactory.getCurrentSession();
    }

    protected HibernateTemplate createHibernateTemplate(
            SessionFactory sessionFactory) {
        return new HibernateTemplate(sessionFactory);
    }

    @Override
    protected void checkDaoConfig() throws IllegalArgumentException {
        if (this.hibernateTemplate == null) {
            throw new IllegalArgumentException("'sessionFactory' or 'hibernateTemplate' is required");
        }
    }
    
    protected final Session getSession(boolean allowCreate)
            throws DataAccessResourceFailureException, IllegalStateException {
        return (!allowCreate ? SessionFactoryUtils.getSession(
                getSessionFactory(), false) : SessionFactoryUtils.getSession(
                getSessionFactory(),

     this.hibernateTemplate.getEntityInterceptor(),    this.hibernateTemplate.getJdbcExceptionTranslator()));
    }

    protected final DataAccessException convertHibernateAccessException(
            HibernateException ex) {
        return this.hibernateTemplate.convertHibernateAccessException(ex);
    }

    protected final void releaseSession(Session session) {
        SessionFactoryUtils.releaseSession(session, getSessionFactory());
        if(null!=session)session=null;
    }

    public final void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }

    public final HibernateTemplate getHibernateTemplate() {
        return this.hibernateTemplate;
    }
}

USER_INFO表的Dao類UserInfoDao類的代碼以下所示：

package  com.amigo.dao;
import  org.springframework.stereotype.Repository;

@Repository
public   class  UserInfoDao  extends  BaseHibernateDao  {
}

  業務邏輯層

接口類IHelloService的代碼以下：

package  com.amigo.service;
public   interface  IHelloService  {
    public int addUser(String userName) throws Exception;;
}

實現類HelloService類的代碼以下：

package  com.amigo.service;
import  javax.annotation.Resource;

import  org.apache.commons.logging.Log;
import  org.apache.commons.logging.LogFactory;
import  org.springframework.stereotype.Repository;
import  org.springframework.stereotype.Service;

import  com.amigo.dao.UserInfoDao;
import  com.amigo.model.UserInfo;

@Service( " helloService " )
@Repository
public   class  HelloService  implements  IHelloService  {
    private static final Log log = LogFactory.getLog(HelloService.class);
    private UserInfoDao userDao;

    public UserInfoDao getUserDao() {
        return userDao;
    }

    @Resource
    public void setUserDao(UserInfoDao userDao) {
        this.userDao = userDao;
    }

    @Override
    public int addUser(String userName) throws Exception {
        log.info("----------------addUser---------------");
        UserInfo userInfo = new UserInfo();
        userInfo.setUserName(userName);
        userDao.getSession().save(userInfo);
        return 1;
    }
}

 控制層

   控制類HelloControllor類接收userName參數，並調用相應的Service類將用戶名保存到USER_INFO表中，該類的代碼以下：

package  com.amigo.web;

import  javax.annotation.Resource;
import  javax.servlet.http.HttpServletRequest;
import  javax.servlet.http.HttpServletResponse;

import  org.apache.commons.logging.Log;
import  org.apache.commons.logging.LogFactory;
import  org.springframework.stereotype.Controller;
import  org.springframework.web.bind.annotation.RequestMapping;
import  org.springframework.web.bind.annotation.ResponseBody;
import  com.amigo.service.IHelloService;

@Controller
@RequestMapping( " /test " )
public   class  HelloControllor  {
    private static final Log log = LogFactory.getLog(HelloControllor.class);

    private IHelloService helloService;

    public IHelloService getHelloService() {
        return helloService;
    }

    @Resource
    public void setHelloService(IHelloService helloService) {
        this.helloService = helloService;
    }

    @RequestMapping("/hello.do")
    public @ResponseBody 
        String sayHello(HttpServletRequest request, HttpServletResponse response) throws Exception {
        request.setCharacterEncoding("UTF-8");
        String userName = request.getParameter("userName");
        log.info("userName=" + userName);
        int resultCode = helloService.addUser(userName);
        String rspInfo = "你好!" + userName + ",操做結果碼=" + resultCode;
        response.setHeader("Content-type","text/html;charset=UTF-8"); 
        response.getOutputStream().write(rspInfo.getBytes("UTF-8"));
        return "";
    }
}

@Controller註解標識一個控制器，@RequestMapping註解標記一個訪問的路徑；若是@RequestMapping註解在類級別上，則表示一相對路徑，在方法級別上，則標記訪問路徑；

、測試

測試時能夠經過訪問http://localhost:8080/springmvctest/test/hello.do?userName=amigo777，經過userName參數將用戶名添加到USER_INFO表中。

從實例代碼能夠看出，POJO、DAO層、Service層和Controller層都是採用註解的方式將service、dao注入的，減小了配置量，方便了開發工做。
