package com.milan.util;import java.util.Vector;/** * 響應對象 * */public class HttpRespons {    String urlString;           int defaultPort;       String file;         String host;         String path;         int port;         String protocol;         String query;         String ref;         String userInfo;         String contentEncoding;         String content;         String contentType;         int code;         String message;         String method;         int connectTimeout;         int readTimeout;         Vector<String> contentCollection;    public String getUrlString() {        return urlString;    }    public void setUrlString(String urlString) {        this.urlString = urlString;    }    public int getDefaultPort() {        return defaultPort;    }    public void setDefaultPort(int defaultPort) {        this.defaultPort = defaultPort;    }    public String getFile() {        return file;    }    public void setFile(String file) {        this.file = file;    }    public String getHost() {        return host;    }    public void setHost(String host) {        this.host = host;    }    public String getPath() {        return path;    }    public void setPath(String path) {        this.path = path;    }    public int getPort() {        return port;    }    public void setPort(int port) {        this.port = port;    }    public String getProtocol() {        return protocol;    }    public void setProtocol(String protocol) {        this.protocol = protocol;    }    public String getQuery() {        return query;    }    public void setQuery(String query) {        this.query = query;    }    public String getRef() {        return ref;    }    public void setRef(String ref) {        this.ref = ref;    }    public String getUserInfo() {        return userInfo;    }    public void setUserInfo(String userInfo) {        this.userInfo = userInfo;    }    public String getContentEncoding() {        return contentEncoding;    }    public void setContentEncoding(String contentEncoding) {        this.contentEncoding = contentEncoding;    }    public String getContent() {        return content;    }    public void setContent(String content) {        this.content = content;    }    public String getContentType() {        return contentType;    }    public void setContentType(String contentType) {        this.contentType = contentType;    }    public int getCode() {        return code;    }    public void setCode(int code) {        this.code = code;    }    public String getMessage() {        return message;    }    public void setMessage(String message) {        this.message = message;    }    public String getMethod() {        return method;    }    public void setMethod(String method) {        this.method = method;    }    public int getConnectTimeout() {        return connectTimeout;    }    public void setConnectTimeout(int connectTimeout) {        this.connectTimeout = connectTimeout;    }    public int getReadTimeout() {        return readTimeout;    }    public void setReadTimeout(int readTimeout) {        this.readTimeout = readTimeout;    }    public Vector<String> getContentCollection() {        return contentCollection;    }    public void setContentCollection(Vector<String> contentCollection) {        this.contentCollection = contentCollection;    }     }

3、創建 java請求類

java請求類需要繼承AbstractJavaSamplerClient類和實現Serializable接口。

package com.milan.test;import java.io.IOException;import java.io.Serializable;import java.util.HashMap;import java.util.Map;import org.apache.jmeter.config.Arguments;import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;import org.apache.jmeter.samplers.SampleResult;import com.milan.util.HttpHelper;public class JavaRequestTest extends AbstractJavaSamplerClient implements        Serializable {    // 設置默認值    public Arguments getDefaultParameters() {        Arguments params = new Arguments();        params.addArgument("url", "http://www.baidu.com");        params.addArgument("kw", "你好");        return params;    }    public SampleResult runTest(JavaSamplerContext arg0) {        SampleResult sr = new SampleResult();        sr.setSampleLabel("java請求測試-MiLan");        sr.sampleStart();//        // http請求        String strReturn = "";        try {            strReturn = Send(arg0);        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        // 設置返回值        sr.setResponseData(strReturn, null);        sr.setDataType(SampleResult.TEXT);        System.out.println(strReturn);        sr.setSuccessful(true);        sr.sampleEnd();        return sr;    }    // http請求    private String Send(JavaSamplerContext arg0) throws IOException {        String url = arg0.getParameter("url", "http://www.baidu.com");        String kw = arg0.getParameter("kw", "MiLan");        Map<String, String> map = new HashMap<String, String>();        map.put("kw", kw);        return HttpHelper.sendGet(url, map).getContent();    }}

4、生成jar包

生成jar包的時候，不能選擇jmeter的jar包。只能選擇自己有用到的jar包。剛才用到了javax.servlet-api-3.1.0.jar，所以要把這個jar包一起打包。

需要用fatjar打包，不然可能找不到引用jar包的類。不知道怎么用fatjar打包的，可以參考http://www.companysz.com/milanmi/p/4651904.html
