Spring+SpringMVC+Hibernate整合实例讲解

使用Maven构建项目，用pom.xml引入相应jar,配置以下文件

创建spring.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns="http://www.springframework.org/schema/beans"
  xmlns:aop="http://www.springframework.org/schema/aop"
  xmlns:context="http://www.springframework.org/schema/context"
  xmlns:tx="http://www.springframework.org/schema/tx"
  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-4.3.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
  <!-- 整合Hibernate -->
  <context:property-placeholder location="classpath:db.properties"/>
  
  <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="${jdbc.driver}"/>
    <property name="jdbcUrl" value="${jdbc.url}"/>
    <property name="user" value="${jdbc.username}"/>
    <property name="password" value="${jdbc.password}"/>
  </bean>
  
  <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
    <property name="mappingLocations" value="classpath:mapping/*.hbm.xml"></property>
  </bean>
  
  <bean name="hibernateTransactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"></property>
  </bean>
  
  <tx:advice id="txAdvice" transaction-manager="hibernateTransactionManager"></tx:advice>  
  
  <aop:config>
    <aop:pointcut expression="execution(* com.forum.service.*.*(..))" id="pointCut"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut"/>
  </aop:config>
  
  <context:component-scan base-package="com.forum">
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
  </context:component-scan>
</beans>

创建springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns="http://www.springframework.org/schema/beans"
  xmlns:aop="http://www.springframework.org/schema/aop"
  xmlns:context="http://www.springframework.org/schema/context"
  xmlns:mvc="http://www.springframework.org/schema/mvc"
  xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
    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-4.3.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">
  <!-- 配置MessageConvertor -->
  <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
    <property name="messageConverters">
      <list>
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
          <property name="supportedMediaTypes">
            <list>
              <value>application/json;charset=utf-8</value>
            </list>
          </property>
        </bean>
      </list>
    </property>
  </bean>
  
  <!-- 配置模板引擎 -->
  <bean name="templateResolver" class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">
    <property name="prefix" value="/WEB-INF/views/"/>
    <property name="suffix" value=".html"/>
    <property name="templateMode" value="HTML"/>
    <property name="cacheable" value="false"/>
    <property name="characterEncoding" value="UTF-8"/>
  </bean>
  
  <bean name="templateEngine" class="org.thymeleaf.spring5.SpringTemplateEngine">
    <property name="templateResolver" ref="templateResolver"/>
  </bean>
  
  <bean class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine"/>
    <property name="characterEncoding" value="utf-8"/>
  </bean>
  
  <mvc:annotation-driven></mvc:annotation-driven>
  
  <mvc:default-servlet-handler/>
  
  <context:component-scan base-package="com.forum">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
  </context:component-scan>
</beans>

创建hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory>
    <!-- 设置方言 -->
    <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
    <!-- 配置生成SQL的打印 -->
    <property name="hibernate.show_sql">true</property>
    <property name="hibernate.format_sql">true</property>
    <!-- 设置自动生成表 -->
    <property name="hibernate.hbm2ddl.auto">update</property>
    <property name="hibernate.connection.isolation">4</property>
  </session-factory>
</hibernate-configuration>

创建db.properties

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/数据库名
jdbc.username="" #这里自己填写
jdbc.password="" #这里自己填写

整合SSH的配置文件已经完成
