bboss将一个组件同时发布为webservice,hessian,http三种服务方法介绍

bboss将一个组件同时发布为webservice,hessian,http三种服务方法介绍

1.概述
bboss提供cxf webservice（基于cxf 2.7.6），hessian(基于4.0.7),http(基于bboss mvc)三种服务的一次性便捷发布机制。

2.服务定义
在bboss ioc配置文件中将组件同时配置为webservice、hessian、http三种服务：

<properties>
	<!-- 生成令牌控制配置文件
	author：biaoping.yin
    CopyRight：bboss
    Date:2011.4.13
	-->
	<property name="/token/*.freepage" ws:servicePort="tokenService" 
	hessian:servicePort="tokenService"
	class="com.demo.common.action.TokenController" />
</properties>

从配置中可以知道：
com.demo.common.action.TokenController是服务组件实现类，首先通过name="/token/*.freepage" 将其配置为一个mvc控制器，以便接受http请求方式的服务调用，通过ws:servicePort="tokenService" 将其发布为一个cxf webservice服务，通过hessian:servicePort="tokenService"将其发布为一个hessian服务。hessian:servicePort是可选的配置，bboss 默认将所有的组件都发布为hessian服务，默认采用name属性作为hessian服务的唯一标识，无需额外配置，这里指定hessian:servicePort是由于name属性对应的值/token/*.freepage作为mvc请求的地址匹配模式，也可以作为hessian服务的标识，但是作为hessian服务的位置地址标识不太友好，所以通过hessian:servicePort指定了hessian的标识为tokenService。
3.服务接口定义
为了让TokenController正确地发布为webservice和hessian服务，还必须定义一个接口TokenService：

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService(name = "TokenService", targetNamespace = "com.demo.common.action.TokenService")
public interface TokenService {
	public @WebResult(name = "authTempToken", partName = "partAuthTempToken")
	String genAuthTempToken(
			@WebParam(name = "appid", partName = "partAppid") String appid,
			@WebParam(name = "secret", partName = "partSecret") String secret,
			@WebParam(name = "account", partName = "partAccount") String account)
			throws Exception;

	public @WebResult(name = "dualToken", partName = "partDualToken")
	String genDualToken(
			@WebParam(name = "appid", partName = "partAppid") String appid,
			@WebParam(name = "secret", partName = "partSecret") String secret,
			@WebParam(name = "account", partName = "partAccount") String account)
			throws Exception;

	public @WebResult(name = "publicKey", partName = "partPublicKey")
	String getPublicKey(
			@WebParam(name = "appid", partName = "partAppid") String appid,
			@WebParam(name = "secret", partName = "partSecret") String secret)
			throws Exception;
	public @WebResult(name = "tempToken", partName = "partTempToken") String genTempToken() throws Exception;
}

接口方法和接口上添加了webservice服务相关的注解，要实现接口的服务组件：

@WebService(name="TokenService",targetNamespace="com.demo.common.action.TokenService")
public class TokenController implements TokenService {
	/**
	 * 获取令牌请求
	 * @param request
	 * @return
	 */
	public @ResponseBody String getToken(HttpServletRequest request)
	{
		MemTokenManager memTokenManager = org.frameworkset.web.token.MemTokenManagerFactory.getMemTokenManagerNoexception();
		if(memTokenManager != null)//如果开启令牌机制就会存在memTokenManager对象，否则不存在
		{
			return  memTokenManager.buildDToken(request);
		}
		else
		{
			return null;
		}
	}
	
	public @ResponseBody String genTempToken() throws Exception
	{
		MemTokenManager memTokenManager = org.frameworkset.web.token.MemTokenManagerFactory.getMemTokenManagerNoexception();
		if(memTokenManager != null)//如果开启令牌机制就会存在memTokenManager对象，否则不存在
		{
			return  memTokenManager.genTempToken();
		}
		else
		{
			return null;
		}
	}
	
	/**
	 * 获取令牌请求
	 * @param request
	 * @return
	 * @throws Exception 
	 */
	public @ResponseBody String genAuthTempToken(String appid,String secret,String account) throws Exception
	{
		MemTokenManager memTokenManager = org.frameworkset.web.token.MemTokenManagerFactory.getMemTokenManagerNoexception();
		if(memTokenManager != null)//如果开启令牌机制就会存在memTokenManager对象，否则不存在
		{
			return  memTokenManager.genAuthTempToken(appid, secret, account);
		}
		else
		{
			return null;
		}
	}
	
	/**
	 * 获取令牌请求
	 * @param request
	 * @return
	 * @throws Exception 
	 */
	public @ResponseBody String genDualToken(String appid,String secret,String account) throws Exception
	{
		MemTokenManager memTokenManager = org.frameworkset.web.token.MemTokenManagerFactory.getMemTokenManagerNoexception();
		if(memTokenManager != null)//如果开启令牌机制就会存在memTokenManager对象，否则不存在
		{
			long dualtime = 30l*24l*60l*60l*1000l;
			return  memTokenManager.genDualToken(appid, secret, account,dualtime);
		}
		else
		{
			return null;
		}
	}
	/**
	 * 获取应用公钥
	 * @param appid
	 * @param secret
	 * @return
	 * @throws Exception 
	 */
	public @ResponseBody String getPublicKey(String appid,String secret) throws Exception
	{
		MemTokenManager memTokenManager = org.frameworkset.web.token.MemTokenManagerFactory.getMemTokenManagerNoexception();
		if(memTokenManager != null)//如果开启令牌机制就会存在memTokenManager对象，否则不存在
		{
			return  memTokenManager.getPublicKey(appid, secret);
		}
		else
		{
			return null;
		}
	}
	
	/**
	 * 获取令牌请求
	 * http://localhost:8081/demo/token/getParameterToken.freepage
	 * @param request
	 * @return
	 */
	public @ResponseBody String getParameterToken(HttpServletRequest request)
	{
		MemTokenManager memTokenManager = org.frameworkset.web.token.MemTokenManagerFactory.getMemTokenManagerNoexception();
		if(memTokenManager != null)//如果开启令牌机制就会存在memTokenManager对象，否则不存在
		{
			return  memTokenManager.buildParameterDToken(request);
		}
		else
		{
			return null;
		}
	}

服务方法返回参数前都有@ResponseBody 注解，这个是用来标注mvc框架将返回的String数据作为响应返回到客户端。

4.服务的三种客户端调用方法
定义好调用参数

String appid = "appid";
String secret = "xxxxxxxxxxxxxxxxxxxxxx";
String account = "yinbp";

hessian服务方式申请token（hessian提供的标准调用模式）

HessianProxyFactory factory = new HessianProxyFactory();
//String url = "http://10.25.192.142:8081/context/hessian?service=tokenService";
String url = "http://192.168.1.101:8080"+request.getContextPath()+"/hessian?service=tokenService";
TokenService tokenService = (TokenService) factory.create(TokenService.class, url);
String token = tokenService.genAuthTempToken(appid, secret, account);
//token = tokenService.genDualToken(appid, secret, account);

webservice方式申请token(cxf提供的服务调用模式)

url = "http://192.168.1.101:8080/demo/cxfservices/tokenService";
JaxWsProxyFactoryBean WSServiceClientFactory = new  JaxWsProxyFactoryBean();
WSServiceClientFactory.setAddress(url);
WSServiceClientFactory.setServiceClass(TokenService.class);
tokenService = (TokenService)WSServiceClientFactory.create();
token = tokenService.genAuthTempToken(appid, secret, account);
//token = tokenService.genDualToken(appid, secret, account);

http请求方式申请令牌

url = "http://192.168.1.101:8080/demo/token/genAuthTempToken.freepage?appid="+appid + "&secret="+secret + "&account="+account;
//url = "http://10.25.192.142:8081/demo/token/genDualToken.freepage?appid="+appid + "&secret="+secret + "&account="+account;
token = org.frameworkset.spi.remote.http.HttpReqeust.httpPostforString(url);

5.HttpReqeust组件介绍
HttpReqeust是bboss最新版本3.8.0中提供的http服务组件，专门用来执行http请求，并将处理结果返回给客户端，提供了以下主要方法：

//发送请求，参数url对应服务地址，返回String类型的响应
public static String httpPostforString(String url) throws Exception
//发送请求，参数url对应服务地址，params中存放了请求的参数对，返回String类型的响应
public static String httpPostforString(String url,Map<String, Object> params) throws Exception
//发送请求，参数url对应服务地址，参数params中存放了请求的参数对，参数files中存放了要上传到服务端的文件信息，返回String类型的响应
public static String httpPostforString(String url,Map<String, Object> params,
			Map<String, File> files) throws Exception
