第一步: 

1.1创建erp_parent父工程

         -- 创建子工程

             entity  --实体类

             dao

             biz

             web

         -- 给子工程添加依赖关系     

           entity >  dao > biz > web

1.2整合SSH和pom.xml的配置

</project>                                                                               

第二步:创建包in.itcast.erp.*和类

         2.1:在entity层创建dep(部门)实体和hbm.xml映射文件

        

        2.2:在dao层创建接口和实现类继承HibernateDaoSupport

              在dao接口创建 list<Dep> getList();//列出所有部门方法

              实现类调用数据库 getHibernateTemplate().find("from Dep");

              在dao层src/test/创建测试类

              事例代码:

                  void test(){

                        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath*:applicationContext_*.xml");

             IDepDao depDap = (IDepDao) ac.getBean("depDao");

             System.out.println(depDap.getList().size());

                   }

                  编写applicationContext_dao.xml

                         <bean id="depDao" class="cn.itcast.erp.dao.impl.DepDao">

          <property name="sessionFactory" ref="sessionFactory" ></property>

          </bean>

                   编写applicationContext_datasource.xml

                          <!-- 数据源 -->

     <bean id="dataSource" class=" com.mchange.v2.c3p0.ComboPooledDataSource">

          <property name="driverClass" value="oracle.jdbc.driver.OracleDriver"></property>

          <property name="jdbcUrl" value="jdbc:oracle:thin:@192.168.112.10:1521:ORCL"></property>

          <property name="user" value="erp31"></property>

          <property name="password" value="itcast"/>

     </bean>   

     

     <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">

          <property name="dataSource" ref="dataSource"/>

          <property name="hibernateProperties">

               <props>

                    <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>

                    <prop key="hibernate.show_sql">true</prop>

                    <prop key="hibernate.format_sql">true</prop>

                    <prop key="hibernate.hbm2ddl.auto">none</prop>

               </props>

          </property>

          <property name="mappingLocations" value="classpath:cn/itcast/erp/entity/*.hbm.xml">

          </property>

     </bean>

           2.3:在biz层创建接口和实现类

                在biz接口创建 list<Dep> getList();方法

                实现接口 并注入 private dao 提供set方法

                调用dao getList事例代码

                  getList(){

                         return depDao.getList();

                  }

                在实现类上面开启事物注解  @Transactional

                    编写applicationContext_biz.xml

                <bean id="depBiz" class="cn.itcast.erp.biz.impl.DepBiz">

          <property name="depDao" ref="depDao" ></property>

        </bean>

                编写applicationContext_tx.xml

                <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">

          <property name="sessionFactory" ref="sessionFactory"/>

        </bean>

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

         2.4:在web层创建Action类

                  注入 private biz 提供set方法

                  调用biz 事例代码:

                  list(){

                     List<Dep> list = depBiz.getList();

          // 转成json字符串

          String jsonString = JSON.toJSONString(list);

          HttpServletResponse response = ServletActionContext.getResponse();

          // 通知浏览读取内容使用的编码

          response.setContentType("text/html;charset=utf-8");

          try {

               response.getWriter().write(jsonString);

          } catch (IOException e) {

               e.printStackTrace();

          }

                 }

                   编写applicationContext_action.xml

                      <bean id="depAction" class="cn.itcast.erp.action.DepAction" scope="prototype">

               <property name="depBiz" ref="depBiz" ></property>

           </bean>

                  编写struts.xml

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

               <action name="dep_*" class="depAction" method="{1}" />

         </package>

 

第三步:

      编写web.xml 

      <context-param>

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

          <param-value>classpath*:applicationContext_*.xml</param-value>

      </context-param>

     <listener>

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

     </listener>

     <filter>

          <filter-name>openSessionInView</filter-name>

          <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>

     </filter>

     <filter-mapping>

          <filter-name>openSessionInView</filter-name>

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

     </filter-mapping>

     <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>

        使用easyui1.3.5创建dep.html
