java - Jmeter采样器看不到资源文件

Question

我正在为 JMeter 创建自定义采样器。我能够将我的 jar 导入到库中，采样器在 GUI 中可见，但字段显示不正确。

这是我的代码。

自定义.java

public class Custom extends AbstractSampler implements TestBean {

  private String email = "";

  public Custom() {
    super();
  }

  public SampleResult sample(Entry entry) {
    SampleResult res = new SampleResult();
    res.setSampleLabel(getName());
    res.setResponseData(("Hello " + getEmail()).getBytes());
    res.setSuccessful(Boolean.TRUE);
    return res;
  }

  public void setEmail(String email){ this.email = email; }
  public String getEmail(){ return email; }
}

自定义BeanInfo.java

public class CustomBeanInfo extends BeanInfoSupport {

  protected CustomBeanInfo() {
    super(Custom.class);

    createPropertyGroup("contact", new String[]{
      "email"
    });

    PropertyDescriptor p = property("email");
    p.setValue(NOT_UNDEFINED, Boolean.TRUE);
    p.setValue(DEFAULT, "asd");
  }
}

CustomResources.properties

displayName=Custom Sampler
email.displayName=Email Address
email.shortDescription=User Email Address
contact.displayName=Contact

这就是它在 JMeter GUI 中的样子。我的猜测是属性文件未正确附加到采样器或未执行构造函数。

编辑 1:添加了 pom.xml 文件内容

编辑 2:使用采样器(将其添加到线程组)时，日志中出现以下错误

2016/03/25 09:28:23 WARN  - jmeter.testbeans.gui.GenericTestBeanCustomizer: org.apache.jmeter.protocol.java.sampler.Custom#email(java.lang.String) does not appear to have been configured 

Answer 1

问题是构造函数的修饰符

protected CustomBeanInfo() {

必须是

public CustomBeanInfo() {

不要问为什么 com/sun/beans/finder/InstanceFinder.class 在没有消息的情况下捕获异常:

protected T instantiate(Class<?> var1, String var2) {
    if (var1 != null) {// 90
        try {
            if (var2 != null) {// 92
                var1 = ClassFinder.findClass(var2, var1.getClassLoader());// 93
            }

            if (this.type.isAssignableFrom(var1)) {// 95
                return var1.newInstance();// 96
            }
        } catch (Exception var4) {// 99
            ;
        }
    }

    return null;// 103
}
