Spring+SpringMVC+SpringDataJpa集成

一使用maven工具导入jar包

二Spring集成SpringDataJpa

配置applicationContext.xml文件

<?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:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:jpa="http://www.springframework.org/schema/data/jpa"
       xsi:schemaLocation="
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd
         http://www.springframework.org/schema/tx
         http://www.springframework.org/schema/tx/spring-tx.xsd
        ** http://www.springframework.org/schema/data/jpa
         http://www.springframework.org/schema/data/jpa/spring-jpa.xsd**">

<!-- 扫描service部分的包 -->
    <context:component-scan base-package="cn.itsource.aisell.service" />
    <context:property-placeholder location="classpath:jdbc.properties" />

<!-- 配置连接池 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <!--连接数据4个属性 -->
        <property name="driverClassName" value="${jdbc.driverClassName}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <!--maxActive: 最大连接数量 -->
        <property name="maxActive" value="150" />
        <!--minIdle: 最小空闲连接 -->
        <property name="minIdle" value="5" />
        <!--maxIdle: 最大空闲连接 -->
        <property name="maxIdle" value="20" />
        <!--initialSize: 初始化连接 -->
        <property name="initialSize" value="30" />
        <!-- 用来配置数据库断开后自动连接的 -->
        <!-- 连接被泄露时是否打印 -->
        <property name="logAbandoned" value="true" />
        <!--removeAbandoned: 是否自动回收超时连接 -->
        <property name="removeAbandoned" value="true" />
        <!--removeAbandonedTimeout: 超时时间(以秒数为单位) -->
        <property name="removeAbandonedTimeout" value="10" />
        <!--maxWait: 超时等待时间以毫秒为单位 1000等于60秒 -->
        <property name="maxWait" value="1000" />
        <!-- 在空闲连接回收器线程运行期间休眠的时间值,以毫秒为单位. -->
        <property name="timeBetweenEvictionRunsMillis" value="10000" />
        <!-- 在每次空闲连接回收器线程(如果有)运行时检查的连接数量 -->
        <property name="numTestsPerEvictionRun" value="10" />
        <!-- 1000 * 60 * 30 连接在池中保持空闲而不被空闲连接回收器线程 -->
        <property name="minEvictableIdleTimeMillis" value="10000" />
        <property name="validationQuery" value="SELECT NOW() FROM DUAL" />
    </bean>

<!-- 集成hibernate的jpa功能 -->
    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!--待扫描的实体类包，不再需要persistence.xml了 -->
        <property name="packagesToScan" value="**扫描的实体类包**" />
        <!-- 3.配置JPA的实现 -->
        <!-- private JpaVendorAdapter jpaVendorAdapter; -->
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <!-- org.springframework.orm.jpa.vendor.AbstractJpaVendorAdapter -->
                <!-- private boolean showSql = false;是否显示sql语句 -->
                <property name="showSql" value="true" />
                <!-- private boolean generateDdl = false;是否建表 -->
                <property name="generateDdl" value="**false**" />
                <!-- private String databasePlatform;原来方言 -->
                <property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
            </bean>
        </property>
    </bean>

<!-- Jpa 事务配置 -->
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>
    <!-- 注解声明式事务管理 -->
    <tx:annotation-driven />

**<!-- Spring Data Jpa****配置 ******************************************-->
    <!-- base-package:扫描的包 -->
    <jpa:repositories base-package="cn.itsource.pss.repository" transaction-manager-ref="transactionManager" entity-manager-factory-ref="entityManagerFactory" />

</beans>

三Spring集成SpringMVC

配置applicationContext-mvc.xml

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc.xsd
    ">
    <!-- 对静态资源进行放行 -->
    <mvc:default-servlet-handler />
    <!-- 扫描controller部分的包 -->
    <!-- @Component组件, @Repository持久层, @Service业务逻辑层, and @Controller控制器 -->
    <context:component-scan base-package="cn.itsource.pss.web" />
    <!-- 添加mvc对@RequestMapping等注解的支持 -->
    <mvc:annotation-driven />

<!-- ViewResolver 视图解析器 (struts2视图类型类似) -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 设置视图路径的前后缀，该配置可以让我们写视图路径的时候更简单。 -->
        <!-- 希望跳转jsp是[/WEB-INF/views/前缀][xxx变量][.jsp后缀] -->
        <!-- * @see #setPrefix -->
        <property name="prefix" value="/WEB-INF/views/" />
        <!-- * @see #setSuffix -->
        <property name="suffix" value=".jsp" />
    </bean>

<!-- 错误：提示告诉开发者你没有配置文件上传解析器。 -->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 设置上传文件的最大尺寸为1MB -->
        <property name="maxUploadSize">
            <value>1048576</value>
        </property>
    </bean>
</beans>

四web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         id="WebApp_ID" version="3.1">

    <!-- 读取SpringMVC -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- 启动Spring的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

   <!--** **配置解决中文乱码的问题 -->
    <filter>
        <filter-name>characterEncodingFilter</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>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 配置核心控制器-->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <!-- 告诉SpringMVC到哪里去找配置文件 -->
            <param-name>contextConfigLocation</param-name>
            <!-- 注意:这里只读取springmvc的xml -->
            <param-value>classpath:applicationContext-mvc.xml</param-value>
        </init-param>
        <!-- Servlet默认在每一次访问的时候创建 -->
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>
