以上为基础配置，下面是各种框架整合的spring的配置 applicationContext.xml

#SSH（spring+springMVC+hibernate）框架整合

<!-- 1.注解扫描包，加载bean -->
    <context:component-scan base-package="com.xxx">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <!-- 2.加载属性文件 -->
    <bean id="annotationPropertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">

                <value>classpath:init.properties</value>
            </list>
        </property>
    </bean>
    <!-- 3.配置数据源：jdbc+pool -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
        destroy-method="close">
        <property name="driverClass" value="${jdbc.driver}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <!-- 请求超时时间 -->
        <property name="checkoutTimeout" value="30000" />
        <!-- 每60秒检查所有连接池中的空闲连接。默认值: 0，不检查 -->
        <property name="idleConnectionTestPeriod" value="30" />
        <!-- 连接数据库连接池最大空闲时间 -->
        <property name="maxIdleTime" value="30" />
        <!-- 连接池初始化连接数 -->
        <property name="initialPoolSize" value="5" />
        <property name="minPoolSize" value="5" />
        <property name="maxPoolSize" value="20" />
        <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 -->
        <property name="acquireIncrement" value="5" />
    </bean>
    
    <!-- 4.配置hibernate的SessionFactory -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!-- 注入数据源 相关信息看源码 -->
        <property name="dataSource" ref="dataSource" />
        <!-- hibernate配置信息 -->
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
                <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
                <!-- 开启二级缓存 ehcache -->
                <prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop>
                <prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop>
                <prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop>
                <prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path}
                </prop>
            </props>
        </property>
        <!-- 扫描hibernate注解配置的entity 
        <property name="packagesToScan" value="com.qf.wobb.model" />-->
        <property name="packagesToScan">  
            <list>
                <value>com.xxx.bz.model</value>
            </list>
        </property>
    </bean>
    
    <!-- 5.配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager"/>

第4步需要配置Hibernate的sessionFactory，并在第5步注入到事物管理器（HibernateTransactionManager）中。
Dao实现类需要注入SessionFactory

@Resource
private SessionFactory sessionFactory;

#面向JPA的SSH

        <!-- 连接池初始化连接数 -->

        <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 -->
        <property name="acquireIncrement" value="5"/>
    </bean>

    <!-- 4.配置jpa+hibernate -->
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
        </property>
        <!--扫描实体类-->
        <property name="packagesToScan" value="com.xyl.esys.entity"/>
        <!-- hibernate 配置 -->
        <property name="jpaProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>

                </prop>
            </props>
        </property>
    </bean>

    <!-- 5.配置事务 - jpa -->
    <bean id="transactionManager"
          class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>

与普通SSH框架不同的是在第四步和第五步
Dao实现类需要注入EntityManager

@PersistenceContext
private EntityManager em;

#SSS（spring+springMVC+springData）框架整合
只需在面向JPA的SSH配置最后加上一步即可

<!-- 6.配置 SpringData -->
<jpa:repositories base-package="com.xyl.esys.dao"
     entity-manager-factory-ref="entityManagerFactory"
     transaction-manager-ref="transactionManager"/>

#SSM（spring+springMVC+mybatis）整合

<!-- 1.注解扫描包，加载bean -->
    <context:component-scan base-package="com.xxx">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>
    <!-- 2.加载属性文件 -->
    <bean id="annotationPropertyConfigurer"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:init.properties</value>
            </list>
        </property>
    </bean>
    <!-- 3.配置数据源：jdbc+pool -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
        destroy-method="close">
        <property name="driverClass" value="${jdbc.driver}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <!-- 请求超时时间 -->
        <property name="checkoutTimeout" value="30000" />
        <!-- 每60秒检查所有连接池中的空闲连接。默认值: 0，不检查 -->
        <property name="idleConnectionTestPeriod" value="30" />
        <!-- 连接数据库连接池最大空闲时间 -->
        <property name="maxIdleTime" value="30" />
        <!-- 连接池初始化连接数 -->
        <property name="initialPoolSize" value="5" />
        <property name="minPoolSize" value="5" />
        <property name="maxPoolSize" value="20" />
        <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。默认值: 3 -->
        <property name="acquireIncrement" value="5" />
    </bean>

    <!-- 4.配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager" />

    <!-- 5.配置mybatis -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg index="0" ref="sqlSessionFactory" />
    </bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.xxx.sys.dao" />
    </bean>
    <!-- 自动扫描mapping.xml文件，**表示迭代查找 ，也可在mybatis-config.xml中单独指定xml文件 -->
		<!--<property name="mapperLocations" value="classpath:mapper/*.xml" />-->

		<!-- 具体指定xml文件，可不配
		<property name="configLocation" value="classpath:mybatis-config.xml" />
		-->

第4步直接配置事务管理器（DataSourceTransactionManager），并注入dataSource；

第5步配置mybatis。

采用注解方式定义DAO接口即可，无需实现类。

@Mapper
public interface IEntityDao {

    /**
     * @param e
     */
    @Insert("INSERT INTO sys_xxx (id, description, dicType, name, val) "
            + "VALUES (#{id}, #{description}, #{dicType}, #{name}, #{val})")
    public void create (Entity e);
}

#以上框架与mybatis混合开发，如：ssh+m ,sss+m
将SSM第5步配置加入上述框架中，即可实现各框架和mybatis的混合配置，因为mybatis仅仅需要dataSource而已。
