Struts2+Spring2.5+Hibernate3.2实例教程(2-7)V0.1

3） 配置文件修改
3.1）删除Bitrac\src\com\albertsong\bitrac\dao\Member.hbm.xml
3.2)建目录Bitrac\src\META-INF，在这个目录下面新建一个文件persistence.xml，内容如下：

1. <? xml version = " 1.0 " encoding = " UTF-8 " ?>
2. < persistence   xmlns = " http://java.sun.com/xml/ns/persistence "
3.     xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance "
4.     xsi:schemaLocation = " http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd "
5.     version = " 1.0 " >
6.     < persistence-unit   name = " punit " >
7.     </ persistence-unit >
8. </ persistence >

3．3）修改web.xml文件，添加
<filter>
        <filter-name>OpenEntityManagerInViewFilter</filter-name>
        <filter-class>
            org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter
        </filter-class>
    </filter>

    <filter-mapping>
        <filter-name>OpenEntityManagerInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

3．4）修改applicationContext.xml，修改后内容如下：

1. <? xml version = " 1.0 " encoding = " UTF-8 " ?>
2. < beans   xmlns = " http://www.springframework.org/schema/beans "
3.     xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance "
4.     xmlns:aop = " http://www.springframework.org/schema/aop "
5.     xmlns:tx = " http://www.springframework.org/schema/tx "
6.     xsi:schemaLocation = "
7.     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
8.     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
9.     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd " >
10.  
11.     < bean
12.         class = " org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor "   />
13.    
14.     < bean   id = " entityManagerFactory "
15.         class = " org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean " >
16.         < property   name = " dataSource " ref = " dataSource " />
17.         < property   name = " jpaVendorAdapter " >
18.             < bean
19.                 class = " org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter " >
20.                 < property   name = " database " value = " MYSQL " />
21.                 < property   name = " showSql " value = " true " />
22.             </ bean >
23.         </ property >
24.     </ bean >
25.  
26.     < bean   id = " dataSource "  
27.         class = " org.springframework.jdbc.datasource.DriverManagerDataSource " >
28.         < property   name = " driverClassName " value = " com.mysql.jdbc.Driver " />  
29.         < property   name = " url " value = " jdbc:mysql://localhost:3306/bitrac " />  
30.         < property   name = " username " value = " root " />
31.         < property   name = " password " value = "" />
32.     </ bean >
33.    
34.     < bean   id = " transactionManager "
35.         class = " org.springframework.orm.jpa.JpaTransactionManager " >
36.         < property   name = " entityManagerFactory " ref = " entityManagerFactory " />
37.     </ bean >
38.    
39.     < tx:annotation-driven   transaction-manager = " transactionManager " />
40.    
41.     < bean   id = " memberDao " class = " com.albertsong.bitrac.dao.MemberDaoImpl " />
42.    
43.     < bean   name = " adminAction " class = " com.albertsong.bitrac.action.AdminAction " scope = " prototype " >
44.         < property   name = " memberDao " ref = " memberDao " />
45.     </ bean >
46. </ beans >

4）运行程序
启动Tomcat，浏览http://localhost:8080/bitrac/
正常的话，我们已经完成了一个最简单的Struts2+Spring2.5+JPA(Hibernate)程序了。

源代码这里下载：
Lib 源代码不带jar，这里包括了当前需要的所有jar，解压后放到/WebRoot/WEB-INF/lib下。

后记：
如果仔细的看完这两章，那么对于Java Web开发常用的操作和一般流程应该熟悉了。从第三章开始，将正式开始Bitrac博客程序的开发。

Javaeye对文章的长度有限制，很好。
一直想做一个完整的例子再发出来，结果写得很长，分开贴也很累，还不如写一点儿贴一点儿。
