Hessian实战施用之设置Hessian报文头信息

Hessian实战应用之设置Hessian报文头信息

?使用Hessian中，在Java模拟客户端的时候可能存在需要向Hessian报文头信息设置一些参数，如token信息。默认的HessianProxyFactory对没有方法设置报文头的方法。以下方法可以做到。

1.新建自己的HessianProxyFactory继承com.connection.ForwardHessianConnectionFactory

/** * 接口调用的HessianConnectionFactory * 重写Hessian的HessianURLConnectionFactory向报文头添加接入端的控制信息 *  * @author ZhangMingxue * @version 1.0 * @time 2013下午04:49:30 * @JDK 1.6 */public class ForwardHessianConnectionFactory extendsHessianURLConnectionFactory {// 报文头参数private Map<String, String> headerParamMap = null;/** * 报文头参数，通过构造方法传入 *  * @param headerParamMap */public ForwardHessianConnectionFactory(Map<String, String> headerParamMap) {this.headerParamMap = headerParamMap;}@Overridepublic HessianConnection open(URL url) throws IOException {HessianURLConnection hessianURLConnection = (HessianURLConnection) super.open(url);if (null != headerParamMap && !headerParamMap.isEmpty()) {Set<String> keySet = headerParamMap.keySet();for (String key : keySet) {// 向报文头中添加参数hessianURLConnection.addHeader(key, headerParamMap.get(key));}}return hessianURLConnection;}}

?2.创建HessianProxyFactory

/** * 创建HessianProxyFactory *  * @param jsc * @return */public HessianProxyFactory createHessianProxyFactory(JavaSamplerContext jsc) {HessianProxyFactory hessianProxyFactory = new HessianProxyFactory();// Request的Header设置参数Map<String, String> headerParamMap = addRequestHeaderParams(jsc);// 创建自己的HessianConnectionFactoryHessianConnectionFactory hessianConnectionFactory = new ForwardHessianConnectionFactory(headerParamMap);hessianConnectionFactory.setHessianProxyFactory(hessianProxyFactory);hessianProxyFactory.setConnectionFactory(hessianConnectionFactory);return hessianProxyFactory;}

??

/** * 接口接用请求转发 *  * @param jsc * @return */public Map<String, String> addRequestHeaderParams(JavaSamplerContext jsc) {Map<String, String> headerParamMap = new HashMap<String, String>();headerParamMap.put("xxxxx1", jsc.getParameter("id"));headerParamMap.put("xxxxx2", jsc.getParameter("authToken"));return headerParamMap;}

?3.客户端使用自己的HessianProxyFactory，获取远程接口。

?

public IPropose buildRemoterServer(JavaSamplerContext jsc) {HessianProxyFactory hessianProxyFactory = createHessianProxyFactory(jsc);IPropose iPropose = null;try {StringBuffer url = createServerURL(jsc,"xxx.xxx.xxxx.xxxxServlet");iPropose = (IPropose) hessianProxyFactory.create(IPropose.class,url.toString());} catch (MalformedURLException e) {e.printStackTrace();}return iPropose;}

?

@Overridepublic SampleResult runTest(JavaSamplerContext jsc) {SampleResult result = new SampleResult();result.sampleStart();try {IPropose iPropose = buildRemoterServer(jsc);Object bo = iPropose.createPl();//调用远程服务器方法result.sampleEnd();} catch (Exception e) {result.setSuccessful(false);result.setResponseMessage(e.getMessage());e.printStackTrace();}return result;}

?以上的JavaSamplerContext对象可以简单理解为Map类型的参数，由jmeter测试工具创建，主要用于存放测试的参数，根Hessian没有关系，主要是我的客户端是Jmeter，如果是客户端采用的是其它技术可以把JavaSamplerContext换成Map.
