Spring3+Hibernate4+SpringMVC整合Ext：项目架构搭建



前言

       前段时间突然想用SpringMVC结合Ext做一个框架原型，整合后发现SpringMVC配合Ext简直天衣无缝，当然SpringMVC结合别的UI框架应该也是天衣无缝的。SpringMVC比Struts2确实要强大很多，特别对于Ext框架JSON数据的完美支撑，开发起来相当舒服。Spring3整合Hibernate4的时候可能有点问题，跟Spring2+Hibernate3有很大的区别，区别在于Hibernate4实现了对事务的管理，所以Spring针对Hibernate4就没有提供HibernateDaoSupport这个类。

       整合有个原则是分框架的整合，比如我们先整合Spring、再整合SpringMVC接着整合Hibernate

   整合Spring

        整合的第一步将Jar引入到工程里面来，引入之后更改配置项目配置。下面是项目的web.xml文件的详细信息：

其实Spring的配置跟以前没多大区别，关键就是设置Spring的启动监听器和Spring配置文件的地址，下面是spring-base.xml的内容：

42.

<?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:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:context="http://www.springframework.org/schema/context"       xsi:schemaLocation="       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd       ">    <!-- 扫描注解Bean -->    <context:component-scan base-package="com.avicit">        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>    </context:component-scan>    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">        <property name="locations">            <list>            <value>classpath*:com/avicit/resource/jdbc/jdbc.properties</value>            <value>classpath*:com/avicit/resource/hibernate/hibernate.properties</value>            </list>        </property>    </bean>     <!-- 国际化的消息资源文件 -->    <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">        <property name="basenames">            <list>                <!-- 在web环境中一定要定位到classpath 否则默认到当前web应用下找  -->                <value>classpath:com/avicit/resource/message/messages</value>            </list>        </property>        <property name="defaultEncoding" value="UTF-8"/>        <property name="cacheSeconds" value="60"/>    </bean>        <import resource="classpath*:com/avicit/resource/spring/spring-dao.xml"/></beans>

这一段配置也没有什么特别地方，加载jdbc.properties数据库配置和hiberate.properties配置文件、设置扫描Annotation注册Bean的包，但是下面有段配置可能不是很熟悉：

[html] view plaincopyprint?

1. <context:component-scan base-package="com.avicit">  
2.     <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>  
3. </context:component-scan>  

    <context:component-scan base-package="com.avicit">        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>    </context:component-scan>

这里设置了不扫描的Annotation的类型，这是因为org.springframework.stereotype.Controller是SpringMVC的控制器的注解，使用这个注解注册的Bean在SpringMVC容器启动的时候已经实例化了，所以在Spring容器里面就不需要进行实例化了。

   整合SpringMVC

在web.xml文件的配置中可以看到这么一段配置：

[html] view plaincopyprint?

1.  <servlet>  
2.      <servlet-name>spring-dispatcher</servlet-name>  
3.      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
4.         <init-param>  
5. <param-name>contextConfigLocation</param-name>  
6. <param-value>classpath*:com/avicit/resource/spring/spring-dispather.xml</param-value>  
7.      </init-param>  
8.      <load-on-startup>1</load-on-startup>  
9.  </servlet>  
10.   
11.  <servlet-mapping>  
12.      <servlet-name>spring-dispatcher</servlet-name>  
13.      <url-pattern>/</url-pattern>  
14.  </servlet-mapping>  

    <servlet>        <servlet-name>spring-dispatcher</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>           <init-param><param-name>contextConfigLocation</param-name><param-value>classpath*:com/avicit/resource/spring/spring-dispather.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>spring-dispatcher</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>

这个就是SpringMVC的配置，配置SpringMVC的容器也可以说是调度器，下面看下spring-dispather.xml中的配置：

这一部分配置是依据官方来的文档来的，大家看看文档就可以明白这段配置，在这里就不赘述了。但是这里有很关键的一处配置是官方文档没有提到的，也是整合Hiberate4中关键的配置，如果没有配置Hibernate肯定跑不起来，这段配置：

[html] view plaincopyprint?

1. <!-- 开启controller注解支持 -->  
2. <!-- 注：如果base-package=com.avicit 则注解事务不起作用 TODO 读源码 -->  
3. <context:component-scan base-package="com.avicit">  
4.     <context:include-filter type="annotation"  
5.         expression="org.springframework.stereotype.Controller" />  
6.     <context:exclude-filter type="annotation"  
7.         expression="org.springframework.stereotype.Service" />  
8. </context:component-scan>  

<!-- 开启controller注解支持 --><!-- 注：如果base-package=com.avicit 则注解事务不起作用 TODO 读源码 --><context:component-scan base-package="com.avicit"><context:include-filter type="annotation"expression="org.springframework.stereotype.Controller" /><context:exclude-filter type="annotation"expression="org.springframework.stereotype.Service" /></context:component-scan>

这里配置了扫描Controller，通过Controller注解注册的Bean是SpringMVC的控制器，但是为什么要排除Service注解呢？这是因为通过Service注册的Bean是要进行事务处理的。要生成动态代理进行事务控制，所以如果不排除的话，Service注册的Bean是不带事务处理的。所以在整合Hibernate的时候就会报没有事务的异常。

   整合Hibernate

Hibernate在Spring中如何配置，也就是spring-dao.xml：

Hibernate的配置跟Hibernate3没有很大的区别，唯一的区别就是所有的操作都必须开启事务。

   关于Ext的整合

Spring3＋Hibernate4的框架整合差不多，后面会写如何实现SpringMVC整合Ext，Ext的Grid组件提供了RESTful方式的访问而SpringMVC也支持这种访问。如何处理对Ext的分页，如何返回json数据给Ext，那才是更有意思的部分。
