【Spring九】三大框架的整合

三大框架整合的顺序：先hibernate,后spring,struts2
   1、建立工程
   2、设置编码格式
   3、设置所有的jsp的编码格式（preference->jsp）
   4、导入jar包

   5、写hibernate的配置文件、持久化类、映射文件

Classes.hbm.xml:

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

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

<hibernate-mapping>

     <class name="com.oterman.domain.Classes" >

           <id name= "cid" type ="long" length="5">

               <column name= "cid"></column >

               <generator class= "increment"></generator >

           </id>

           <property name= "cname" length ="20"></ property>

           <property name= "description" length="200" ></property>

     </class >

</hibernate-mapping>

================================
hibernate.cfg.xml:

<?xml version= '1.0' encoding ='utf-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >

<hibernate-configuration>

<session-factory>

     <property name="connection.username"> root</ property>

     <property name="connection.password"> root</ property>

     <property name="connection.url">

          jdbc:mysql:// localhost:3306/hibernate_itheima03

     </property >

     <property name="dialect">

          org.hibernate.dialect.MySQLDialect

     </property >

     <property name="connection.driver_class">

          com.mysql.jdbc.Driver

     </property >

     

     <property name="hbm2ddl.auto"> update</ property>

     <property name="show_sql"> true</ property>

     <mapping resource="com/oterman/domain/Classes.hbm.xml" />

</session-factory>

</hibernate-configuration>

 

   6、写dao
   7、写service
   8、spring的配置文件

       (1)、写sessionFactory

applicationContext.xml:

<beans xmlns="http://www.springframework.org/schema/beans"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      xmlns:aop="http://www.springframework.org/schema/aop"

      xmlns:tx= "http://www.springframework.org/schema/tx"

      xsi:schemaLocation="

          http://www.springframework.org/schema/beans

          http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

          http://www.springframework.org/schema/aop

          http://www.springframework.org/schema/aop/spring-aop-2.5.xsd

          http://www.springframework.org/schema/tx

          http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" >

     <import resource="applicationContext-db.xml"/>

     <import resource="applicationContext-classes.xml"/>

     

</beans>  

=======================================================

applicationContext-db.xml:

<beans xmlns="http://www.springframework.org/schema/beans"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

      xmlns:tx= "http://www.springframework.org/schema/tx"

      xsi:schemaLocation="

          http://www.springframework.org/schema/beans

          http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

          http://www.springframework.org/schema/aop

          http://www.springframework.org/schema/aop/spring-aop-2.5.xsd

          http://www.springframework.org/schema/tx

          http://www.springframework.org/schema/tx/spring-tx-2.5.xsd" >

           <!-- 配置sessionFactory及aop事务 -->

           <bean id= "sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" >

               <property name= "configLocation" >

                    <value> classpath:hibernate/hibernate.cfg.xml</value >

               </property>

           </bean>

          

           <bean id= "transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" >

               <property name= "sessionFactory">

                    <ref bean= "sessionFactory"/>

               </property>

           </bean>

          

           <tx:advice id= "tx" transaction-manager="transactionManager" > 

               <tx:attributes>

                    <tx:method name= "save*" read-only="false" />

               </tx:attributes>

           </tx:advice>

          

           <aop:config>

           <!--      <aop:pointcut expression="execution(* com.oterman.dao.impl.*.*(..))" id="trans"/> -->

               <aop:pointcut expression="execution(* com.oterman.service.*.*(..))" id= "trans"/>

               <aop:advisor advice-ref="tx" pointcut-ref="trans" />

           </aop:config>

</beans>

       (2)、测试

     @Test

     public void testSessionFactory(){

          ApplicationContext context= new ClassPathXmlApplicationContext("spring/applicationContext.xml" );

          SessionFactory sessionFactory=(SessionFactory) context.getBean("sessionFactory" );

     }

       (3)、写dao和service

       (4)、测service
       (5)、aop的配置
       (6)、测试service,看service是否是代理对象

     @Test

     public void testSaveClasses(){

          ApplicationContext context= new ClassPathXmlApplicationContext("spring/applicationContext.xml" );

          ClassesService classesService=(ClassesService) context.getBean("classesService" );

          

          Classes classes= new Classes();

          classes.setCname( "hah");

          classesService.saveClasses(classes);

          

     }

   9、写action
   10、把action放入到spring中
   11、写action的配置文件

struts.xml:

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

<!DOCTYPE struts PUBLIC

      "-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"

      "http://struts.apache.org/dtds/struts-2.1.7.dtd" >

<struts>

   <!-- 配置文件改了以后不用重新启动 -->

   <constant name="struts.devMode" value= "true"/>

   <!--全局错误处理  -->

   <package name="struts-global" namespace="/" extends="struts-default" >

           <global-results>

               <result name= "errHandler" type ="chain">

                    <param name="actionName" >errorProcessor </param>

               </result>

           </global-results>

          

           <global-exception-mappings>

               <exception-mapping exception="java.lang.Exception"

                    result= "errHandler" />

           </global-exception-mappings>

           <action name= "errorProcessor" class="com.oterman.exception.ErrorProcessor" >

               <result> error.jsp</result >

           </action>

     </package >

 

   <include file="struts2/struts-classes.xml"></include >

</struts>  

================================
struts-classes.xml:

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

<!DOCTYPE struts PUBLIC

      "-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN"

      "http://struts.apache.org/dtds/struts-2.1.7.dtd" >

<struts>

     <package name="classes"  namespace="/" extends="struts-global" >

           <!--class属性要和applicationContext.xml的id属性相对应，这样action才能有spring来产生  -->

           <action name= "classesAction_*" method ="{1}" class="classesAction" >

               <result> index.jsp</result >

           </action>

     </package >

</struts>  

   12、写web.xml配置文件 

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

<web-app version= "2.5"

      xmlns= "http://java.sun.com/xml/ns/javaee"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" >

  <welcome-file-list >

    <welcome-file >index.jsp </welcome-file>

  </welcome-file-list >

 

     <!--

     初始化spring容器时，会按照如下的规则加载spring的配置文件：

             1、如果在web.xml文件中有contextConfigLocation参数

                 则会按照该参数所指定的路径加载配置文件

             2、如果在web.xml文件中没有配置<context- param>，则会根据默认的路径

                 加载配置文件(WEB-INF/applicationContext.xml)

             3、在web- inf下的路径可以有如下的写法：

                 WEB-INF/*../application-*. xml

         说明：在web- inf下的配置文件没有办法进行测试

       -->

     <listener >

           <listener-class> org.springframework.web.context.ContextLoaderListener</listener-class >

     </listener >

     <context-param >

           <param-name> contextConfigLocation</param-name >

           <param-value> classpath:spring/applicationContext.xml</param-value >

     </context-param >

     

     <!--加载struts容器

          加载了4个配置文件

              default.properties

              struts-default.xml

              struts-plugin.xml

          多加载了一个struts2-spring- plugin-2.1.8.1.jar 包下的xml文件

          <bean type="com.opensymphony.xwork2.ObjectFactory" name="spring"

                class="org.apache.struts2.spring.StrutsSpringObjectFactory" />

          <constant name="struts.objectFactory" value="spring" />

           说明：该类改变了action的创建方式，交由spring容器来创建action，

                 先从spring容器中查找action,根据struts2的配置文件中的action元素的class属性的值和spring容器中配置文件中的ID值做匹配

       -->

     <filter >

           <filter-name> struts2</ filter-name>

           <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter </filter-class>

     </filter >

     <filter-mapping >

           <filter-name> struts2</ filter-name>

           <url-pattern> /*</ url-pattern>

     </filter-mapping >

 

</web-app>

   13、写jsp
   14、测试
