用myEclipse8.5 + flex4 + Spring BlazeDS Integration + Blaze + Gilead整合过程

以下是框架整合顺序（前提条件是，myEclipse8.5与Flash Bulider4整合在一起）；

1、先建立一个普通web工程

2、右键webroot，选择import -> general ->file system，选中BlazeDS文件夹，会自动把BlazeDS的配置文件自动加入web工程

3、添加flex项目类型，修改flex的src路径和flex服务器路径

4、配置流行的S2SH框架（在web.xml配置struts2的action时候要这样<url-pattern>*.action</url-pattern>，否则日后flex不能与java、通信）

5、配置 Spring BlazeDS Integration 和 Gilead

--------------------------------------------------------------------------------

特别说明一下在使用gilead框架时候用到以下2个类的作用；

这2个类是必须的，不用改是官方的！！

类名：SpringApplicationContext 

view plaincopy to clipboardprint?
01.import org.springframework.context.ApplicationContext;  
02.import org.springframework.web.context.support.WebApplicationContextUtils;  
03. 
04.public class SpringApplicationContext {  
05.      
06.    private static SpringApplicationContext instance = null;  
07. 
08.    private SpringApplicationContext() {  
09.        super();  
10.    }  
11.      
12.    public static SpringApplicationContext getInstance() {  
13.        if (instance == null) {  
14.            return new SpringApplicationContext();  
15.        } else {  
16.            return instance;  
17.        }  
18.    }  
19.      
20.    public Object getSessionFactory() {  
21.        ApplicationContext appContext = WebApplicationContextUtils  
22.                .getWebApplicationContext(flex.messaging.FlexContext  
23.                        .getServletConfig().getServletContext());  
24.        return appContext.getBean("sessionFactory");  
25.    }  
26.      
27.} 
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

public class SpringApplicationContext {
 
 private static SpringApplicationContext instance = null;

 private SpringApplicationContext() {
  super();
 }
 
 public static SpringApplicationContext getInstance() {
  if (instance == null) {
   return new SpringApplicationContext();
  } else {
   return instance;
  }
 }
 
 public Object getSessionFactory() {
  ApplicationContext appContext = WebApplicationContextUtils
    .getWebApplicationContext(flex.messaging.FlexContext
      .getServletConfig().getServletContext());
  return appContext.getBean("sessionFactory");
 }
 
}

作用：这个类是用于适配的，取得sessionFactory

类名：SpringFactory

39.        }

41.        public Object lookup() {

 }
}

作用：用来返回实际的Spring管理的bean

 

在flex中的类与java端的类进行绑定的方法；

view plaincopy to clipboardprint?
01.package vo{  
02.    import mx.collections.ArrayCollection;  
03.      
04.    import net.sf.gilead.pojo.actionscript.LightEntity;  
05.      
06.    /**再现Java端的User类， 
07.     * 否则Hibernate无法存储信息 
08.     * *.as类必须和 *.java类 完全一样，字段个数，字段类型 
09.     * 否则出错 
10.     */ 
11.    [Bindable]  
12.    [RemoteClass(alias="com.oa.beans.User")]  
13.    public class UserVO extends LightEntity{  
14.        /**id*/ 
15.        public var id:int;  
16.        /**用户名*/ 
17.        public var username:String;  
18.        /**密码*/ 
19.        public var password:String; 
package vo{
 import mx.collections.ArrayCollection;
 
 import net.sf.gilead.pojo.actionscript.LightEntity;
 
 /**再现Java端的User类，
  * 否则Hibernate无法存储信息
  * *.as类必须和 *.java类 完全一样，字段个数，字段类型
  * 否则出错
  */
 [Bindable]
 [RemoteClass(alias="com.oa.beans.User")]
 public class UserVO extends LightEntity{
  /**id*/
  public var id:int;
  /**用户名*/
  public var username:String;
  /**密码*/
  public var password:String;

建一个和Java类完全一样的 as类，as类要继承LightEntity

然后加上
[RemoteClass(alias="com.oa.beans.User")]
也就是为该类对应一个Java为别名
