Maven搭建SpringMVC+Hibernate项目详解

今天复习一下SpringMVC+hibernate的搭建，本来想着将spring-Security权限控制框架也映入其中的，但是发现内容太多了，Spring-Security的就留在下一篇吧，这篇主要搭建SpringMVC4.1.4和Hibernate4.3.8，之前也打了好多SpringMVC的，这部分已经非常的熟悉了，毕竟业开发过一年多SpringMVC的，这次持久层采用Hibernate，数据源采用c3p0，数据库暂采用MySQL，主要是想复习一下Hibernate。搭建SpringMVC+Hibernate的框架的思路如下：

     1、设计数据库：设计好表结构，最好符合3NF，采用Hibernate tools将设计好的表自动生成对应的实体entity。 

     1、创建Maven项目，按需映入Maven包依赖。

     2、搭建Spring：配置Spring对控件层Bean的注入。

     3、搭建Hibernate：配置数据源，配置SessionFactory，配置事务，以及二级缓存ehcache的配置。

     4、测试Spring+Hibernate的框架搭建，写单元测试JUnit，测试事务配置等。

     5、映入SpringMVC：配置SpringMVC配置信息。

     6、配置web.xml容器

     7、测试三个框架的整合：Maven编译打包部署服务器，测试。

1、数据库设计

       设计一个权限、角色、用户的表。自然如果一个用户可以有多个角色，一个角色多个用户所拥有；一个角色拥有多个权限，一个权限对应多个角色。所以按照数据库表结构设计，符合3NF的话我们需要5张表进行存在。表的具体信息就不列出了（可以下在源码，里面还有数据库），表关系如下：

       

      这里面ID才用到是Java的UUID（36位）

2、创建Maven项目，编写pom.xml文件

      创建一个Maven的webapp项目，编写pom.xml文件，引入所需的包依赖，我这里就将所需的全部的映入了。

        

      pom.xml文件内容如下:

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

3、引入Spring配置

    编写配置文件，配置文件放在src/main/resources资源目录下（下同）。

   项目所需的配置信息config.properties

1. #application configs  

2.   

3. #jdbc c3p0 config  

4. jdbc.driver = com.mysql.jdbc.Driver  

5. jdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8  

6. jdbc.username = root  

7. jdbc.password = 12345  

8.   

9. #hibernate config  

10. hibernate.dialect = org.hibernate.dialect.MySQLDialect  

11. hibernate.show_sql = true  

12. hibernate.format_sql = false  

13. hibernate.hbm2ddl.auto = update  

14. hibernate.cache.use_second_level_cache = true  

15. hibernate.cache.use_query_cache = true  

16. hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory  

17. hibernate.cache.provider_configuration_file_resource_path = ehcache.xml  

3.1、spring配置

spring.xml的配置文件如下：

 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"
     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">


     <context:property-placeholder location="classpath:config.properties"/>

     <context:component-scan base-package="org.andy.work.service.impl,org.andy.work.dao.impl" />

 beans>

上面spring配置了对应包下组件bean自动注入管理，我们需要将dao,service的实现类交由spring管理，如（@Repository，@Service）。

3.2、引入日志文件配置Log4j

  log4j.properties的配置文件如下：

1. ### set log levels ###  

2. log4j.rootLogger = INFO , C , D , E   

3.   

4. ### console ###  

5. log4j.appender.C = org.apache.log4j.ConsoleAppender  

6. log4j.appender.C.Target = System.out  

7. log4j.appender.C.layout = org.apache.log4j.PatternLayout  

8. log4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n  

9.   

10. ### log file ###  

11. log4j.appender.D = org.apache.log4j.DailyRollingFileAppender  

12. log4j.appender.D.File = ../logs/springmvc_hibernate_demo.log  

13. log4j.appender.D.Append = true  

14. log4j.appender.D.Threshold = INFO   

15. log4j.appender.D.layout = org.apache.log4j.PatternLayout  

16. log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n  

17.   

18. ### exception ###  

19. log4j.appender.E = org.apache.log4j.DailyRollingFileAppender  

20. log4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log   

21. log4j.appender.E.Append = true  

22. log4j.appender.E.Threshold = ERROR   

23. log4j.appender.E.layout = org.apache.log4j.PatternLayout  

24. log4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n  

4、Hibernate配置

      Hibernate的配置主要包括：配置数据源c3p0，配置SessionFactory，配置事务管理器，配置事务管理，其spring-hibernate.xml文件如下：

 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:tx="http://www.springframework.org/schema/tx"

         <property name="dataSource" ref="dataSource" />

         <property name="hibernateProperties">
             <props>

     上面配置了二级缓存，ehcache，相关的具体信息查看上一篇Hibernate二级缓存以及ehcache的搭建配置，下面是二级缓存的配置。

4.1、ehcache.xml的配置

 xml version="1.0" encoding="UTF-8"?>
 <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">
     <diskStore path="D:/ehcache" />

      <defaultCache
             maxElementsInMemory="1000"
             eternal="false"
             timeToIdleSeconds="120"
             timeToLiveSeconds="120"
             maxElementsOnDisk="1000000"
             overflowToDisk="true"
             memoryStoreEvictionPolicy="LRU">

     defaultCache>



     <cache
          name="org.andy.work.entity.AcctUser"
          maxElementsInMemory="2"
          memoryStoreEvictionPolicy="LRU"
          eternal="true"
          diskPersistent="false"
          overflowToDisk="false"
          maxElementsOnDisk="1000000" />



 ehcache>

   上面Hibernate二级缓存ehcache存放磁盘是D:/ehcache

5、生成业务entity实体

      设计好数据表后，Hibernate的实体有工具Hibernate tools自动生成，Eclipse需要安装Hibernate tools插件（我在线安装过几次都不成功，推荐使用links离线安装，附录将介绍），所以不需要手工的书写，下面就贴一个用户信息的实体，AcctUser.java

 package org.andy.work.entity;

 // Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0

     private Set acctRoles = new HashSet(0);

     public AcctUser() {

     }

     public AcctUser(String id, String nickName) {
         this.id = id;
         this.nickName = nickName;
     }

     public AcctUser(String id, String nickName, String telephone,
             Date registerTime, Set acctRoles) {
         this.id = id;
         this.nickName = nickName;
         this.telephone = telephone;
         this.registerTime = registerTime;
         this.acctRoles = acctRoles;
     }

     @Id
     @Column(name = "id", unique = true, nullable = false, length = 36)
     public String getId() {
         return this.id;
     }

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

     @Column(name = "nick_name", nullable = false)
     public String getNickName() {
         return this.nickName;
     }

     public void setNickName(String nickName) {
         this.nickName = nickName;
     }

     @Column(name = "telephone")
     public String getTelephone() {
         return this.telephone;
     }

     public void setTelephone(String telephone) {
         this.telephone = telephone;
     }

     @Temporal(TemporalType.TIMESTAMP)
     @Column(name = "register_time", length = 19)
     public Date getRegisterTime() {
         return this.registerTime;
     }

     public void setRegisterTime(Date registerTime) {
         this.registerTime = registerTime;
     }

     @JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})
     @ManyToMany(fetch = FetchType.LAZY)
     @Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
     @JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) })
     public Set getAcctRoles() {
         return this.acctRoles;
     }

     public void setAcctRoles(Set acctRoles) {
         this.acctRoles = acctRoles;
     }

 }

上面有几个需要注意的：

     上面大多数都是Hibernate tools自动生成的，但是有几个需要手动添加：

              1、如果这个实体使用二级缓存的话，需要添加@cache注解；

              2、如果该实体里面还有集合元素（set， map，list），如果实体要采用二级缓存，那么这些集合元素必须也添加@cache注解。

              3、@JsonIgnoreProperties注解是为了防止SpringMVC在json返回时产生循环输出使用，如果不配置的话就会出现json死循环（还有多对多，一对多的属性时）。

             4、@JsonIgnore这个是在转换成json是忽略该属性，而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})则是忽略acctRoles里面的acctUsers和acctAuthorites属性。

6、创建Dao层

6.1Dao接口

              Dao层和Service层我们肯定采用的是面相接口编程的思想，所以，我们先定义一个通用的Dao接口，GenericDao.java

 package org.andy.work.dao;

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

 /**
  * 创建时间：2015-2-6 下午2:26:42
  *
  * @author andy
  * @version 2.2
  *
  * Dao通用接口
  */

 interface GenericDaoextends Serializable> {

     T load(PK id);

     T get(PK id);

     List findAll();

     void persist(T entity);

     PK save(T entity);

     void saveOrUpdate(T entity);

     void delete(PK id);

     void flush();
 }

            在定义具体的UserDao.java接口

 package org.andy.work.dao;

 import org.andy.work.entity.AcctUser;

 /**
  * 创建时间：2015-2-6 下午2:43:50
  *
  * @author andy
  * @version 2.2
  *
  * 用户Dao接口
  */

 public interface UserDao extends GenericDao {

 }

6.2、Dao层实现类

    我们需要将Dao层的实现类注入为bean，所以需要添加@Repository注解，UserDaoImpl如下：

 package org.andy.work.dao.impl;

 import java.util.List;

 import org.andy.work.dao.UserDao;
 import org.andy.work.entity.AcctUser;
 import org.hibernate.Session;
 import org.hibernate.SessionFactory;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.stereotype.Repository;

 /**
  * 创建时间：2015-2-6 下午2:45:14
  *
  * @author andy
  * @version 2.2
  */
 @Repository("userDao")
 public class UserDaoImpl implements UserDao {

     @Autowired
     private SessionFactory sessionFactory;

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

     @Override
     public AcctUser load(String id) {
         return (AcctUser) this.getCurrentSession().load(AcctUser.class, id);
     }

     @Override
     public AcctUser get(String id) {
         return (AcctUser) this.getCurrentSession().get(AcctUser.class, id);
     }

     @SuppressWarnings("unchecked")
     @Override
     public List findAll() {
         List acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list();
         return acctUsers;
     }

     @Override
     public void persist(AcctUser entity) {
         this.getCurrentSession().persist(entity);

     }

     @Override
     public String save(AcctUser entity) {
         return (String) this.getCurrentSession().save(entity);
     }

     @Override
     public void saveOrUpdate(AcctUser entity) {
         this.getCurrentSession().saveOrUpdate(entity);
     }

     @Override
     public void delete(String id) {
         AcctUser entity = this.load(id);
         this.getCurrentSession().delete(entity);
     }

     @Override
     public void flush() {
         this.getCurrentSession().flush();

     }

 }

7、创建Service层

 7.1、Service层接口

 package org.andy.work.service;

 import java.util.List;

 import org.andy.work.entity.AcctUser;

 /**
  * 创建时间：2015-2-6 下午3:18:57
  *
  * @author andy
  * @version 2.2
  *  userService接口
  */

 public interface UserService {
     AcctUser load(String id);

     AcctUser get(String id);

     List findAll();

     void persist(AcctUser entity);

     String save(AcctUser entity);

     void saveOrUpdate(AcctUser entity);

     void delete(String id);

     void flush();
 }

7.2、service层实现类

   UserServiceImpl就需要注入上面定义的Dao层bean。

 package org.andy.work.service.impl;

 import java.util.List;

 import org.andy.work.dao.UserDao;
 import org.andy.work.entity.AcctUser;
 import org.andy.work.service.UserService;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.stereotype.Service;

 /**
  * 创建时间：2015-2-6 下午3:24:16
  *
  * @author andy
  * @version 2.2 UserService 的实现
  */
 @Service("userService")
 public class UserServiceImpl implements UserService {

     @Autowired
     private UserDao userDao;

     @Override
     public AcctUser load(String id) {
         return userDao.load(id);
     }

     @Override
     public AcctUser get(String id) {
         return userDao.get(id);
     }

     @Override
     public List findAll() {
         return userDao.findAll();
     }

     @Override
     public void persist(AcctUser entity) {
         userDao.persist(entity);
     }

     @Override
     public String save(AcctUser entity) {
         return userDao.save(entity);
     }

     @Override
     public void saveOrUpdate(AcctUser entity) {
         userDao.saveOrUpdate(entity);
     }

     @Override
     public void delete(String id) {
         userDao.delete(id);
     }

     @Override
     public void flush() {
         userDao.flush();
     }

 }

8、测试Spring和Hibernate的整合

    我们可以在src/test/java编写测试类，测试上面的配置，如果测试成功已经基本大功告成。

 package org.andy.work.service;

 import java.util.Date;
 import java.util.List;
 import java.util.UUID;

 import org.andy.work.entity.AcctUser;
 import org.apache.log4j.Logger;
 import org.junit.Test;
 import org.junit.runner.RunWith;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.test.context.ContextConfiguration;
 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

 import com.alibaba.fastjson.JSON;

 /**
  * 创建时间：2015-2-6 下午3:31:07
  *
  * @author andy
  * @version 2.2
  */
 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(locations = { "classpath:spring.xml",
         "classpath:spring-hibernate.xml" })
 public class TestUserService {

     private static final Logger LOGGER = Logger
             .getLogger(TestUserService.class);

     @Autowired
     private UserService userService;

     @Test
     public void save() {
         AcctUser acctUser = new AcctUser();
         acctUser.setId(UUID.randomUUID().toString());
         acctUser.setNickName("andy");
         acctUser.setRegisterTime(new Date());
         acctUser.setTelephone("13022221111");
         String id = userService.save(acctUser);
         LOGGER.info(JSON.toJSONString(id));
     }

 }

9、引入SpringMVC

     添加spring-mvc.xml文件

 xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:mvc="http://www.springframework.org/schema/mvc" 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"
     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">


     <context:component-scan base-package="org.andy.work.controller" />


     <mvc:annotation-driven>

         <mvc:message-converters register-defaults="true">
             <bean
                 class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                 <property name="supportedMediaTypes">
                     <list>
                         <value>text/html;charset=UTF-8value>
                         <value>application/json;charset=UTF-8value>
                     list>
                 property>

             bean>
         mvc:message-converters>
     mvc:annotation-driven>


     <bean
         class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <property name="viewClass"
             value="org.springframework.web.servlet.view.JstlView" />
         <property name="prefix" value="/WEB-INF/views" />
         <property name="suffix" value=".jsp" />
     bean>

 beans>

   上面配置了包扫描Controller，将@Controller注入为spring的bean。以及springmvc的json处理，和视图层的配置。

10、配置web.xml容器

      web容器是web项目的大脑，所以web容器，首先需要引入spring，让spring管理各个框架，并将其注入为bean。然后配置控制层的filter信息。并且配置了springmvc拦截的url为以.hmls结尾的请求。

web.xml文件如下：

 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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     id="WebApp_ID" version="2.5">

11、创建控制层Controller

     控制层UserController

 package org.andy.work.controller;

 import java.util.List;

 import org.andy.work.entity.AcctUser;
 import org.andy.work.service.UserService;
 import org.apache.log4j.Logger;
 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.stereotype.Controller;
 import org.springframework.ui.ModelMap;
 import org.springframework.web.bind.annotation.PathVariable;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.bind.annotation.ResponseBody;

 /**
  * 创建时间：2015-2-7 上午11:49:00
  * @author andy
  * @version 2.2
  * 描述： 用户Controller
  */
 @Controller
 @RequestMapping("/user")
 public class UserController {

     private static final Logger LOGGER = Logger.getLogger(UserController.class);

     @Autowired
     private UserService userService;

     @RequestMapping("/showInfo/{userId}")
     public String showUserInfo(ModelMap modelMap, @PathVariable String userId){
         LOGGER.info("查询用户：" + userId);
         AcctUser userInfo = userService.load(userId);
         modelMap.addAttribute("userInfo", userInfo);
         return "/user/showInfo";
     }

     @RequestMapping("/showInfos")
     public @ResponseBody List showUserInfos(){
         LOGGER.info("查询用户全部用户");
         List userInfos = userService.findAll();
         return userInfos;
     }
 }

12、创建视图层

   在src/main/webapp/WEB-INF/views下 创建user/showInfo.jsp

 <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
 <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
 <%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

 <%
     String path = request.getContextPath();
     String basePath = request.getScheme() + "://"
             + request.getServerName() + ":" + request.getServerPort()
             + path + "/";
 %>
 >
 <html>
 <head>
 <base href="<%=basePath%>" />
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 <script type="text/javascript" src="js/jquery-1.9.1.min.js">script>
 <title>userInfotitle>
 head>
 <body>
     用户信息 昵称： ${userInfo.nickName} 用户id：${userInfo.id} 用户电话:${userInfo.telephone } 注册时间：
     <fmt:formatDate value="${userInfo.registerTime }" pattern="yyyy-MM-dd HH:mm:ss" />
     角色：[
     <c:forEach items="${ userInfo.acctRoles}" var="role">
                         ${role.name }   权限[
                            <c:forEach items="${ role.acctAuthorities}" var="authority">
                              ${authority.name }
                            c:forEach> ]
                       c:forEach>
     ]

     <br /> ajax显示全部用户信息：
     <div id="show_all_user">div>
 body>
 <script type="text/javascript">
     $.ajax({
         type : "get",
         url : "user/showInfos.htmls",
         dataType : "json",
         success : function(data) {
             $(data).each(
                     function(i, user) {
                         var p = "昵称:" + user.nickName + "    电话:"
                                 + user.telephone + "    注册时间:"
                                 + user.registerTime + "    id:" + user.id +
                         "p>";
                         $("#show_all_user").append(p);
                     });
         },
         async : true
     });
 script>
 html>

13、部署服务器测试

          使用Maven打包部署：clean compile  package

          部署到tomcat，测试

          主要测试上面的  http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls

                                  和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls  （json数据返回）

          上面视图层就包含了这两条url请求的测试：

        

     ok，到此Spring+SpringMVC+Hibernate搭建完毕。

喜欢我的文章的，可以关注微信公众号“测试项目开发”，需要什么内容可以在里面提，我看到后会给大家解答。
