struts2+hibernate-jpa+Spring+maven 整合(2)

之前的一篇已经讲到了 spring 与struts2 的整合, 其实对于struts2+hibernate-jpa+Spring 之间的整合的文章已经相当多了,

也相当成熟了,只要不是各自的版本不兼容之外,其他的几乎没啥问题, 不行mybatis那样是不是的冒点让人头疼的事情来

下面修改pom.xml ,把hibernate 的jar 关联进来;

添加spring-hibernate-jpa.xml的配置

添加spring-datasource.xml

<?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"

    <bean

        <!-- <property name="filters" value="stat" /> -->
        <property name="filters" value="mergeStat" />
    </bean>
</beans>

最后修改 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    <!-- contextConfigLocation -->
    <context-param>
        <param-name>contextConfigLocation</param-name>

    <filter>
        <filter-name>encoding</filter-name>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

最后一点META-INF/persistence.xml 必须要有!

应为我是选择在自定义文件中配置数据源, 所以,这里面的内容必须为空,你也可以选择在这里配置你的数据源.但是可配置的属性比较少,但是胜在方便

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
    http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
    version="1.0">

    <persistence-unit name="webUnit" transaction-type="RESOURCE_LOCAL">
    <!-- <properties> -->

    <!-- <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" 
        /> -->

    <!-- <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/sshe?useUnicode=true&amp;characterEncoding=UTF-8" 
        /> -->
    <!-- <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" 
        /> -->

    <!-- <property name="hibernate.connection.username" value="root" /> -->
    <!-- <property name="hibernate.connection.password" value="123123" /> -->

    <!-- <property name="hibernate.max_fetch_depth" value="3" /> -->
    <!-- <property name="hibernate.jdbc.fetch_size" value="20" /> -->
    <!-- <property name="hibernate.jdbc.batch_size" value="10" /> -->

    <!-- <property name="hibernate.show_sql" value="true" /> -->
    <!-- <property name="hibernate.format_sql" value="true" /> -->

    <!-- <property name="hibernate.hbm2ddl.auto" value="update" /> -->

    <!-- <property name="hibernate.timeBetweenEvictionRunsMillis" -->
    <!-- value="12000" /> -->
    <!-- 每隔120秒检查连接池里的空闲连接 ，单位是秒 -->
    <!-- <property name="hibernate.minEvictableIdleTimeMillis" value="1200" 
        /> -->
    <!-- </properties> -->
    </persistence-unit>

</persistence>

整合到此结束, 启动即用,不再废话了!
