maven+springMVC+hibernate4架构

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。

　 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="

　　　　<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"

    <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>

            <param-value>UTF-8</param-value>
