【JavaWeb】springmvc + hibernate整合配置

1. web.xml配置

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
      <display-name>test2</display-name>
      <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
      </welcome-file-list>

       <!-- 统一编码 解决中文乱码问题-->
    <filter>
        <filter-name>charsetEncoding</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>charsetEncoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- spring MVC 配置-->
    <servlet>
         <servlet-name>spring</servlet-name>
         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
         <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
            classpath:application-config.xml<!-- spring的配置文件 -->
            </param-value>

         </init-param>
         <!--设置为1，优先级最高。配置容器在启动的时候就加载这个servlet并实例化-->
         <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- 请求映射 -->
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>*.do</url-pattern><!-- 只拦截.do为后缀的请求给spring处理 -->
    </servlet-mapping>


    </web-app>

2. spring的配置(spring.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:task="http://www.springframework.org/schema/task" xmlns:cache="http://www.springframework.org/schema/cache"
        xmlns:p="http://www.springframework.org/schema/p" 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/task
            http://www.springframework.org/schema/task/spring-task.xsd
        http://www.springframework.org/schema/cache
        http://www.springframework.org/schema/cache/spring-cache.xsd
        http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

        <!-- spring 的配置 -->
        <mvc:annotation-driven>
            <mvc:message-converters register-defaults="true">
                <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                    <constructor-arg value="UTF-8" />
                    <property name="writeAcceptCharset" value="false" />
                </bean>
            </mvc:message-converters>
        </mvc:annotation-driven>
        <!-- 扫描包 -->
        <context:component-scan base-package="controller,entity,dao,service" />
        <!-- 注解配置 -->  
        <context:annotation-config></context:annotation-config>
        <!-- 引入hibernate配置文件文件 -->
        <import resource="spring-hibernate.xml"></import>

        <!-- hibernate ehcache <cache:annotation-driven cache-manager="cacheManager"></cache:annotation-driven> 
            <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"> 
            <property name="cacheManager" ref="ehcache"></property> </bean> <bean id="ehcache" 
            class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:configLocation="classpath:config/ehcache.xml" 
            p:shared="true"/> -->

    </beans>

3. spring-hibernate配置（spring-hibernate.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:jdbc="http://www.springframework.org/schema/jdbc" 
        xmlns:tx="http://www.springframework.org/schema/tx"
        xmlns:aop="http://www.springframework.org/schema/aop"
        xmlns:p="http://www.springframework.org/schema/p"
        xsi:schemaLocation="http://www.springframework.org/schema/jdbc
            http://www.springframework.org/schema/jdbc/spring-jdbc.xsd
            http://www.springframework.org/schema/beans 
            http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/tx 
            http://www.springframework.org/schema/tx/spring-tx.xsd
            http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
            http://www.springframework.org/schema/context 
            http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 数据源和事物的配置 -->
        <context:property-placeholder location="classpath:application.properties"/>

        <!-- sessionFactory -->
        <bean id="sessionFactory" 
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="entity,service" />
    <property name="hibernateProperties">
    <props>
    <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
    <!-- <prop key="hibernate.current_session_context_class">thread</prop>  -->
    </props>
    </property>
    </bean> 

        <!-- dataSource -->
        <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
            destroy-method="close">
            <property name="driverClass" value="${jdbc.driverClassName}" />
            <property name="jdbcUrl" value="${jdbc.url}" />
            <property name="user" value="${jdbc.username}" />
            <property name="password" value="${jdbc.password}" />

            <!-- these are C3P0 properties -->
            <property name="acquireIncrement" value="${c3p0.acquireIncrement}" />
            <property name="minPoolSize" value="${c3p0.minPoolSize}" />
            <property name="maxPoolSize" value="${c3p0.maxPoolSize}" />
            <property name="maxIdleTime" value="${c3p0.maxIdleTime}" />
        </bean>

        <!-- 配置Hibernate事务管理器 -->
    <bean id="transactionManager"
    class="org.springframework.orm.hibernate5.HibernateTransactionManager">
      <property name="sessionFactory" ref="sessionFactory" />
       </bean> 
       <!-- 事物注解配置 -->
       <tx:annotation-driven transaction-manager="transactionManager"/>


    </beans>

注：需要导入c3p0的包

4. 数据库的配置（application.properties）

    #hibernate
    hibernate.max_fetch_depth=3
    hibernate.jdbc.fetch_size=50
    hibernate.jdbc.batch_size=10
    hibernate.show_sql=true
    hibernate.cache.use_second_level_cache=true
    hibernate.cache.use_query_cache=true
    hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory

    jdbc.driverClassName=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/xgp?useSSL=true
    jdbc.username=root
    jdbc.password=****
    jdbc.maxActive=50

    c3p0.acquireIncrement=10
    c3p0.minPoolSize=3
    c3p0.maxPoolSize=200
    c3p0.maxIdleTime=6000
