第一个插件自定义函数(Function)
代码具体如下,生成 jar 放到 lib\ext 目录下即可。
/*代码路径中,一定要放在 functions 目录中,否则 jmeter 会识别自定义函数失败*/
package interfacePerformance.functions;
import java.util.Collection;
import java.util.LinkedList;
import java.util.List;
import org.apache.jmeter.engine.util.CompoundVariable;
import org.apache.jmeter.functions.AbstractFunction;
import org.apache.jmeter.functions.InvalidVariableException;
import org.apache.jmeter.samplers.SampleResult;
import org.apache.jmeter.samplers.Sampler;
public class double2 extends AbstractFunction {
// private static final Logger log = LoggingManager.getLoggerForClass();
private static final List<String> desc = new LinkedList<String>();
/* KEY 要和类名一致,否则无法识别自定义函数 */
private static final String KEY = "__double2";
private Object[] values = null;
static {
desc.add("double2_value");
}
//描述参数
@Override
public List<String> getArgumentDesc() {
// TODO Auto-generated method stub
return desc;
}
//函数执行,返回结果
@Override
public String execute(SampleResult previousResult, Sampler currentSampler) throws
InvalidVariableException {
// TODO Auto-generated method stub
String numberString = ((CompoundVariable) values[0]).execute().trim();
int num;
try {num = Integer.valueOf(numberString);
} catch (Exception e) {
return null;
}
/* 默认返回 String 类型 */
/* num*2 为业务代码 */
return String.valueOf(num * 2);
}
//获取函数引用关键字
@Override
public String getReferenceKey() {
// TODO Auto-generated method stub
return KEY;
}
//设置参数
@Override
public void setParameters(Collection<CompoundVariable> parameters) throws
InvalidVariableException {
// TODO Auto-generated method stub
// 可以检查参数数量,主要包括以下两种方法
checkMinParameterCount(parameters, 1);
checkParameterCount(parameters, 1, 1);
values = parameters.toArray();
}
}
第二个插件采集器(Sampler)
TestSampler.java
import org.apache.jmeter.samplers.AbstractSampler;
import org.apache.jmeter.samplers.Entry;
import org.apache.jmeter.samplers.SampleResult;
/**
* @author nikey
* @date 2020/3/30
*/
public class TestSampler extends AbstractSampler {
public final static String FUNCTION = "function";
@Override
public SampleResult sample(Entry entry) {
SampleResult result = new SampleResult();
result.sampleStart();
// 输出GUI界面所输入的函数方法返回结果
System.out.println(this.getProperty(FUNCTION));
result.sampleEnd();
result.setSuccessful(true);
return result;
}
}
TestSamplerGUI.java
import org.apache.jmeter.samplers.gui.AbstractSamplerGui;
import org.apache.jmeter.testelement.TestElement;
import javax.swing.*;
import java.awt.*;
/**
* @author nikey
* @date 2020/3/30
*/
public class TestSamplerGUI extends AbstractSamplerGui {
private JTextField functionTextField = null;
public TestSamplerGUI(){
init();
}
@Override
public void configure(TestElement element) {
super.configure(element);
functionTextField.setText(element.getPropertyAsString(TestSampler.FUNCTION));
}
private void init() {
JPanel mainPanel = new JPanel(new GridBagLayout());
functionTextField = new JTextField(20);
mainPanel.add(functionTextField);
add(mainPanel);
}
@Override
public TestElement createTestElement() {
// 创建所对应的Sampler
TestElement sampler = new TestSampler();
modifyTestElement(sampler);
return sampler;
}
@Override
public String getLabelResource() {
return this.getClass().getSimpleName();
}
@Override
public void modifyTestElement(TestElement sampler) {
super.configureTestElement(sampler);
if(sampler instanceof TestSampler){
TestSampler testSampler = (TestSampler) sampler;
testSampler.setProperty(TestSampler.FUNCTION,functionTextField.getText());
}
}
@Override
public String getStaticLabel() {
// 设置显示名称
return "TestSampler";
}
private void initFields(){
functionTextField.setText("");
}
@Override
public void clearGui() {
super.clearGui();
initFields();
}
}
