轻松打造J2EE的 SSH 与flash builder整合(由Spring类管理)

在此将我所配置方法,,告知大家..让大家少走弯路

下面将由我来 手把手教大家 如果 配置SSH 以及将flash builder整合到一起

并由Spring类来管理,,使flash builder直接通过AMF访问java后台类方

环境:

My Eclipse 8.5

Struts 1.2

Spring 2

hibernate 3.1

flash builder 4 / 或插件版

1.前期环境

新建项目名为: MyWeb

建包:

com.sshf.study.entity (实体包)

com.sshf.study.dao(数据访问包)

com.sshf.study.biz(业务逻辑)

并在 com.sshf.study.biz 包下

新建接口 IHelloWord.java

并再建包 impl, HellWordImpl.java 类(全速路径 com.sshf.study.biz.impl.HellWordImpl). 并实现IHelloWord接口

代码如下:

 

?

1 2 3 4 5 6 7 8 9 10 11 12

package com.sshf.study.biz; import com.sshf.study.biz.IHelloWord; public class HelloWordImpl implements IHelloWord{     /**      * 测试方法      * @param name      * @return      */     public String sayHello(String name){         return "HelloHello! " + name;     } }

 

稍后我们会 测试调用这个方法!

2.开始SSH搭建.

a.首先加入Spring框架

自己加入DataSource sessionFactory 实体bean DAOBean 以及事务..养成好习惯

以下是我的初期配置(稍后会添加):

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71

<?xml version="1.0" encoding="UTF-8"?> <!-- 导入命名空间--> <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-2.0.xsd         http://www.springframework.org/schema/tx         http://www.springframework.org/schema/tx/spring-tx-2.0.xsd         http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">         <!-- 配置事务管理 -->         <bean id="myHibTxManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">                 <property name="sessionFactory" ref="sessionFactory" />         </bean>                   <!--配置事务管理策略-->         <tx:advice id="txAdvice" transaction-manager="myHibTxManager">                 <tx:attributes>                         <tx:method name="to*" propagation="SUPPORTS" read-only="true" />                         <tx:method name="add*" propagation="REQUIRED" />                         <tx:method name="find*" propagation="REQUIRED" />                 </tx:attributes>         </tx:advice>                   <aop:config>                 <!--指定用于那些地方-->                 <aop:pointcut id="bizMethods" expression="execution(* com.sshf.study.*.impl.*.*(..))" />                  <!-- 织入 -->                    <aop:advisor advice-ref="txAdvice" pointcut-ref="bizMethods" />         </aop:config>         <!-- dataSource -->         <bean id="dataSource"                 class="org.apache.commons.dbcp.BasicDataSource">                 <property name="driverClassName"                         value="com.microsoft.sqlserver.jdbc.SQLServerDriver">                 </property>                 <property name="url" value="jdbc:sqlserver://localhost:1433"></property>                 <property name="username" value="sa"></property>                 <property name="password" value="dongqiao"></property>         </bean>         <bean id="sessionFactory"                 class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">                 <property name="dataSource">                         <ref bean="dataSource" />                 </property>                 <property name="hibernateProperties">                         <props>                                 <prop key="hibernate.dialect">                                         org.hibernate.dialect.SQLServerDialect                                 </prop>                         </props>                 </property>                 <property name="mappingResources">                         <list>                                 <value>entity/ConfigQuestionSecondKind.hbm.xml</value>                                 <value>entity/EngageSubjects.hbm.xml</value>                                 <value>entity/ConfigQuestionFirstKind.hbm.xml</value></list>                 </property>         </bean>                   <!-- DAO -->                   <!-- biz -->         <bean id="HW" class="com.sshf.study.biz.impl.HellWordImpl">         </bean>                             <!-- action -->         </beans>

 

 

 

b.添加Struts支持

如用到Action 一定不要忘了改 代理类 org.springframework.web.struts.DelegatingActionProxy

c.添加hibernate支持.

以上二步省略.. 相信大家都会配..

 

3.开始将flash builder整合到SSH中

a.下载blazeDS包 将WEB-INF 文件夹下的所有文件夹和文件 拷贝到/WebRoot/WEB-INF/目录下

注意:包括web.xml 全覆盖

b.打开Web.xml 进行配置spring

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13

<!--在web.xml中引入Spring的代码-->         <context-param>                 <!-- 参数名为contextConfigLocation -->                 <param-name>contextConfigLocation</param-name>                                   <!-- 配置多个文件之间，以","隔开 -->                 <param-value>/WEB-INF/classes/app.xml</param-value>         </context-param>         <listener>                 <listener-class>                         org.springframework.web.context.ContextLoaderListener                 </listener-class>         </listener>

 

 

 

(此处app.xml为spring配置文件名 默认为applicationContext.xml)

到此为止..SSH配置完毕..部署运行一下..看是否有错误..

如有错误 自己 改正. 在确保SSH集成后无错 方可 继续.!!

以下步骤很重要

b.新建包com.sshf.study.flash

在该包下新建二个类 SpringFactoryInstance.java FlexFactoryImpl.java

SpringFactoryInstance.java代码

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

package com.sshf.study.flash;   import org.apache.commons.logging.Log;   import org.apache.commons.logging.LogFactory;   import org.springframework.beans.BeansException;   import org.springframework.beans.factory.NoSuchBeanDefinitionException;   import org.springframework.context.ApplicationContext;   import org.springframework.web.context.support.WebApplicationContextUtils;   import flex.messaging.FactoryInstance;   import flex.messaging.FlexContext;   import flex.messaging.FlexFactory;   import flex.messaging.config.ConfigMap;   import flex.messaging.services.ServiceException;   public class SpringFactoryInstance extends FactoryInstance {       private Log log = LogFactory.getLog(getClass());       SpringFactoryInstance(FlexFactory factory, String id, ConfigMap properties) {           super(factory, id, properties);       }       public Object lookup() {           System.out.println("3---spring工厂类的方法lookup");           ApplicationContext appContext = WebApplicationContextUtils.getRequiredWebApplicationContext(FlexContext.getServletConfig().getServletContext());           String beanName = getSource();           try {               log.info("Lookup bean from Spring ApplicationContext: " + beanName);               return appContext.getBean(beanName);           } catch (NoSuchBeanDefinitionException nex) {               ServiceException e = new ServiceException();               String msg = "Spring service named '" + beanName + "' does not exist.";               e.setMessage(msg);               e.setRootCause(nex);               e.setDetails(msg);               e.setCode("Server.Processing");               throw e;           } catch (BeansException bex) {               ServiceException e = new ServiceException();               String msg = "Unable to create Spring service named '" + beanName + "'.";               e.setMessage(msg);               e.setRootCause(bex);               e.setDetails(msg);               e.setCode("Server.Processing");               throw e;           } catch (Exception ex) {               ServiceException e = new ServiceException();               String msg = "Unexpected exception when trying to create Spring service named '" + beanName + "'.";               e.setMessage(msg);               e.setRootCause(ex);               e.setDetails(msg);               e.setCode("Server.Processing");               throw e;           }      } }

 

 

FlexFactoryImpl.java代码

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

package com.sshf.study.flash; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import flex.messaging.FactoryInstance; import flex.messaging.FlexFactory; import flex.messaging.config.ConfigMap;  public class FlexFactoryImpl implements FlexFactory {       private Log log = LogFactory.getLog(getClass());               /*override interface method*/       public void initialize(String id, ConfigMap configMap) {           System.out.println("1---flex工厂实现类重写的方法initialize");       }       /*override interface method*/       public FactoryInstance createFactoryInstance(String id, ConfigMap properties) {           System.out.println("2---flex工厂实现类重写的方法createFactoryInstance");           log.info("Create FactoryInstance.");           SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);           instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));           return instance;       }       /*override interface method*/       public Object lookup(FactoryInstance instanceInfo) {           System.out.println("4---flex工厂实现类重写的方法lookup");           log.info("Lookup service object.");           return instanceInfo.lookup();       }   }

 

 

打开/WEB-INF/flex/services-config.xml 配置文件

加入FlexFactory实现类

 

?

1 2 3

<factories>                <factory id="flexFactoryImpl" class="com.sshf.study.flash.FlexFactoryImpl"/> </factories>

 

 

 

 

打开/WEB-INF/flex/remoting-config.xml 配置文件

然后将 services中的factory的实现类所调用的类配置关联

 

?

1 2 3 4 5 6 7 8 9

<destination id="flash">           <properties>               <!-- flexFactory实现类 -->               <factory>flexFactoryImpl</factory>               <!-- 对外的访问类  为spring配置中的bean id -->               <source>HW</source>               <scope>application</scope>           </properties>  </destination>

 

 

到此为止 配置完毕

部署运行..有错误改之

4.新建一个flex 项目

并新建一个mxml

不一一做介绍了..添加一个 文本框 和一个 按钮..

点击 按钮 将 文本框中 字符串 传入到 HelloWordImpl 的 sayHello中.并取返回值 输出

代码如下:

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

以上为整合内容.

由于本人最近较忙..故没有多少时间!!

有时间给大家做一些 控件 以及 其它 与java后台高级交互文章..

that's all ! 董侨 QQ5596152
