Spring的优越性不用我说大家也都很清楚,项目实际开发中最常用的非IOC和AOP莫属。其优越性深受广大ds男的热捧,在项目中如果不是自己写框架技术选型时Spring也是不可或缺的,尤其是跟一些ORM(hibernate,mybatis等)框架结合更是解决了很多人的问题。
下面就讲解一些maven结合Spring跟主流的hibernate4是如何搭建开发环境,如有对spring,hibernate不清楚的地方可以去其他地方查查资料。(之所以没有选择Spring4.0以上,主要原因是Spring4.0以上的主要改变是对JDK8的支持,servlet版本则对3.0支持出色,由于目前系统大多采用JDK6,servlet采用2.5)
Ok废话少说,且看下面配置:
1. 新建maven项目
具体maven如何使用请参考maven分类中maven的用法,这里不再多说。
2. 打开父模块pom.xml 引入spring配置
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>3.2.10.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>3.2.10.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.2.10.RELEASE</version> </dependency>
3. 引入hibernate4配置
<dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>4.3.6.Final</version> </dependency>
4. 配置spring-config.xml(放到classpath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" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:property-placeholder location="classpath:config.properties" />
<bean name="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="url" value="${jdbc_url}" /> <property name="username" value="${jdbc_username}" /> <property name="password" value="${jdbc_password}" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="hibernateProperties"> <props> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> </props> </property> <property name="packagesToScan"> <list> <value>com.duke.test.domain</value> </list> </property> </bean> <bean name="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <tx:annotation-driven transaction-manager="transactionManager" />
<context:component-scan
base-package="com.duke.test.dao.impl,com.duke.test.service.impl" />
</beans>
5. config.properties文件(放到classpath下)
hibernate.dialect=org.hibernate.dialect.Oracle10gDialect jdbc_driverClassName=oracle.jdbc.driver.OracleDriver jdbc_url=jdbc:oracle:thin:@127.0.0.1:1521:orcl jdbc_username=scott jdbc_password=scott hibernate.hbm2ddl.auto=none hibernate.show_sql=true hibernate.format_sql=false jdbc_valid=SELECT 1 FROM DUAL
6. 配置spring-mvc.xml (放到classpath下)
<?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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <context:component-scan base-package="com.duke.test.controller" /> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> </list> </property> </bean> <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:order="3"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <property name="contentType" value="text/html" /> <property name="prefix" value="/WEB-INF/views/" /> <property name="suffix" value=".jsp" /> </bean> </beans>
7. 配置web.xml
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-config.xml</param-value> </context-param> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>dukeMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dukeMVC</servlet-name> <url-pattern>*.htm</url-pattern> </servlet-mapping>
到此maven+spring+hibernate配置已结束。文中有不清楚的可及时给我留言!
