本文主要是介绍Spring3+Hibernate4+SpringMVC整合Ext:项目架构搭建,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
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:
- <?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:
- <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:
- <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:
- <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"

- http://www.springframework.org/schema/mvc

- <!-- 会自动注册了validator ConversionService -->

- <property name="exceptionMappings">
- <props>
- <prop key="java.lang.Exception">
- error
- </prop>
- </props>
- </property>
- </bean>
- </beans>
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:
- <!-- 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。
这篇关于Spring3+Hibernate4+SpringMVC整合Ext:项目架构搭建的文章就介绍到这儿,希望我们推荐的文章对编程师们有所帮助!
