基于restful注解(spring4.0.2整合flex+blazeds＋spring-mvc)<一>

摘自: http://www.blogjava.net/liuguly/archive/2014/03/10/410824.html

参考官网：
1.http://livedocs.adobe.com/blazeds/1/blazeds_devguide/
2.http://docs.spring.io/spring-flex/docs/1.5.2.RELEASE/reference/html/

1）下载blazeds（turnkey4.0.x版本）网址：http://sourceforge.net/adobe/blazeds/wiki/Home/
2）先创建maven工程，然后进入blazeds目录/tomcat/webapps/blazeds/WEB-INF/flex 连flex目录拷贝到src/main/resource目录下(也可以直接拷贝文件)
如图：

3）核心flex相关jar包
    下载spring-flex-core-1.5.2.RELEASE.jar
        blazeds-core-4.0.0.14931.jar
        blazeds-common-4.0.0.14931.jar
          blazeds-proxy-4.0.0.14931.jar
          blazeds-remoting-4.0.0.14931.jar
其中spring-flex-core-1.5.2.RELEASE.jar可以从远程maven中心仓库下载，而blazeds的jar在中心仓库版本有误，如图：

spring容器启动时spring-flex-core-1.5.2依赖的是
blazeds的4.0.0.14931版本，而maven中心仓库并无此jar包，因此以上四个包需手工打入本地maven仓库，打入命令
进入blazeds目录/resources/lib下执行以下maven命令

mvn install:install-file -Dpackaging=jar -DgroupId=com.adobe.blazeds -Dversion=4.0.0.14931 -DartifactId=blazeds-common -Dfile=flex-messaging-common.jar

mvn install:install-file -Dpackaging=jar -DgroupId=com.adobe.blazeds -Dversion=4.0.0.14931 -DartifactId=blazeds-core -Dfile=flex-messaging-core.jar

mvn install:install-file -Dpackaging=jar -DgroupId=com.adobe.blazeds -Dversion=4.0.0.14931 -DartifactId=blazeds-opt -Dfile=flex-messaging-opt.jar

mvn install:install-file -Dpackaging=jar -DgroupId=com.adobe.blazeds -Dversion=4.0.0.14931 -DartifactId=blazeds-proxy -Dfile=flex-messaging-proxy.jar

mvn install:install-file -Dpackaging=jar -DgroupId=com.adobe.blazeds -Dversion=4.0.0.14931 -DartifactId=blazeds-remoting -Dfile=flex-messaging-remoting.jar

至此在工程中即可引入相关jar包.
4) 配置flex/services-config.xml文件红色为修改后内容
channel对于flex来讲，相当于一个通信管道，在flex客户端端表现为endpoint="下面红色字体中endpoint.url属性"

1 <?xml version="1.0" encoding="UTF-8"?>
  2 <services-config>

100     </system>
101

5）搭建spring－mvc框架 web.xml

1     <context-param>
2         <param-name>contextConfigLocation</param-name>
3         <param-value>
4         classpath:applicationContext.xml
5         </param-value>
6     </context-param>
7
8     <listener>
9         <listener-class>
10             org.springframework.web.context.ContextLoaderListener
11         </listener-class>
12     </listener>
13
14     <servlet>
15         <servlet-name>spring-mvc</servlet-name>
16         <servlet-class>
17             org.springframework.web.servlet.DispatcherServlet
18         </servlet-class>
19         <init-param>
20             <param-name>contextConfigLocation</param-name>
21             <param-value>classpath:spring-mvc-servlet.xml</param-value>
22         </init-param>
23         <load-on-startup>1</load-on-startup>
24     </servlet>
25
26     <servlet-mapping>
27         <servlet-name>spring-mvc</servlet-name>
28         <url-pattern>*.htm</url-pattern>
29     </servlet-mapping>
30
31     <servlet>
32         <servlet-name>flex</servlet-name>
33         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
34         <init-param>
35             <param-name>contextConfigLocation</param-name>
36             <param-value>classpath:flex-servlet.xml</param-value>
37         </init-param>
38         <load-on-startup>1</load-on-startup>
39     </servlet>
40
41     <servlet-mapping>
42         <servlet-name>flex</servlet-name>
43         <url-pattern>/messagebroker/amf/*</url-pattern>
44     </servlet-mapping>

因为基于maven工程，配置文件都在src/main/resources目录下，flex和spring-mvc子容器单独配置classpath，否则会自动查找/WEB-INF/<servlet-name>-servlet.xml文件。

6）贴上applicationContext.xml文件，关键点见红色

1 <?xml version="1.0" encoding="UTF-8"?>
2 <beans xmlns="http://www.springframework.org/schema/beans"
3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4     xmlns:p="http://www.springframework.org/schema/p"
5     xmlns:context="http://www.springframework.org/schema/context"
6     xmlns:util="http://www.springframework.org/schema/util"
7     xmlns:mvc="http://www.springframework.org/schema/mvc"
8     xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
9         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
10         http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd
11         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">
12
13     <import resource="flex-context.xml"/>
14
15     
16     <context:component-scan base-package="com.lx.love.web" use-default-filters="false">
17         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
18         <context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
19     </context:component-scan>
20
21     <mvc:annotation-driven>
22         <mvc:message-converters register-defaults="true">
23             <bean class="org.springframework.flex.http.AmfHttpMessageConverter"/>
24           </mvc:message-converters>
25     </mvc:annotation-driven>
26
27
28     <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
29         <property name="contentNegotiationManager"  ref="contentNegotiationManager"/>
30         <property name="defaultViews">
31             <list>
32                 <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>
33                 <bean  class="org.springframework.flex.http.AmfView"/>
34             </list>
35         </property>
36     </bean>
37
38         <bean id= "contentNegotiationManager" class= "org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
39         
40         <property name= "favorPathExtension" value= "true" />
41         
42         <property name= "favorParameter" value= "true" />
43         <property name= "parameterName" value= "format"/>
44         
45         <property name= "ignoreAcceptHeader" value= "false"/>
46          <property name= "mediaTypes"> 
47             <map>
48               <entry key="json" value="application/json"/>
49               <entry key="xml" value="application/xml"/>
50               <entry key="amf" value="application/x-amf"/>
51             </map>
52         </property>
53         
54         <property name= "defaultContentType" value= "application/x-amf" />
55     </bean>
56
57 </beans>

关键点：23行定义将flex客户端传递来的AMF格式消息转换为java可识别的内容
28-36以及50行定义amf格式的返回值也即spring-mvc的返回视图根据http协议头的Accept Header来判断amf格式的返回
7) 上面flex-servlet.xml中引入的flex-context.xml文件内容，红色字体为关键内容

里面的关键点为13行配置message-broker在src/main/resources/下找到services-config.xml文件
14-16为可选增强功能，类似拦截器，异常转换为java可识别的异常等
19-26行用于在控制器类上注解@RemotingDestination(value="flexUserController" , channels={"${channel1},${channel2}"})
可选channels使用。至此xml文件配置完毕。
示例：java服务端关键点红色字体

23 public class FlexUserService {
24
25     @Autowired
26     private UserService userService;
27
28 //    @RemotingExclude
29 //    @RequestMapping(method=RequestMethod.POST)
30 //    public ModelAndView createUser(User user){
31 //        userService.createUser(user);

34 //        mav.addObject("user",user);
35 //        return mav;
36 //    }
37
38     @RemotingInclude
39     @RequestMapping(value="/register",method=RequestMethod.POST)
40     public User register(@RequestBody User user){
41         System.out.println("userName="+user.getUserName());
42         System.out.println("1234567");
43         user.setUserName("ztt");
44         user.setRealName("love");
45         user.setPassword("123456");
46         return user;
47     }
48
49     @RemotingInclude
50     @RequestMapping(value="/test",method=RequestMethod.POST)
51     public String testMy(String userName){
52         System.out.println("userName="+userName);
53         return userName;
54     }
55
56     /**

59      * @param requestEntity
60      * @return
61      * @throws UnsupportedEncodingException
62      */
63     @RemotingInclude
64     @RequestMapping(value="/handler5" , produces={MediaType.APPLICATION_JSON_VALUE})
65     public ResponseEntity<String> handle5(HttpEntity<byte[]> requestEntity)
66     throws UnsupportedEncodingException{
67         String requestHeader = requestEntity.getHeaders().getFirst("MyRequestHeader");
68         byte[] requestBody = requestEntity.getBody();
69         HttpHeaders responseHeaders = new HttpHeaders();
70         responseHeaders.set("lxx", "ztt");
71
72         return new ResponseEntity<String>("Hello World"+requestBody,responseHeaders,HttpStatus.CREATED);
73     }
74
75     @RemotingInclude
76     @RequestMapping(value="/handler")
77     public String handler(@RequestBody String requestBody){
78         System.out.println(requestBody);
79         return "/user/success";
80     }
81
82 }
83

@RemotingDestination(value="flexUserController" , channels={"${channel1}"})
其中value值对应flex客户端：destination值

1         <s:RemoteObject id="remoteObject" destination="flexUserController"  fault="remoteobject1_faultHandler(event)"
2                         endpoint="http://localhost:8081/iloveu/messagebroker/amf" >
3             <s:method name="register" result="getStringResultHandler(event)"/>
4             <s:method name="testMy" result="getStringResultHandler(event)" />
5         </s:RemoteObject>

如果flex客户端传递一个User.as类对象到java服务端

1 package com.lottery.ssc
2 {
3     [Bindable]
4     [RemoteClass(alias="com.lx.love.dto.User")]
5     public class User
6     {
7         private var _userName:String;
8         private var _password:String;
9         private var _realName:String;
10
11         public function User()
12         {
13         }
14
15         public function get realName():String
16         {
17             return _realName;
18         }
19
20         public function set realName(value:String):void
21         {
22             _realName = value;
23         }
24
25         public function get password():String
26         {
27             return _password;
28         }
29
30         public function set password(value:String):void
31         {
32             _password = value;
33         }
34
35         public function get userName():String
36         {
37             return _userName;
38         }
39
40         public function set userName(value:String):void
41         {
42             _userName = value;
43         }
44
45     }
46 }

里面get和set方法的属性名要和java服务器的属性名一致，flex客户端调用方式：

1             var user:User = new User();
2             user.password='123456';
3             user.userName='lx';
4             user.realName='liuguly';
5             remoteObject.register(user);

若java服务端返回一个对象，flex客户端调用方式：打印userName

1         protected function getStringResultHandler(event:ResultEvent):void{
2         var    user:Object = event.result;
3         Alert.show(user.userName);
4         Alert.show(event.result.toString());
5         }

至此，flex客户端和java服务端通信成功，一次完整的http协议请求－响应如下：
flex客户端http请求：以下http消息体出现的鸟文就是amf格式的二进制压缩流

POST /iloveu/messagebroker/amf HTTP/1.1
Host: localhost:8081
