如何使用 Struts2 REST 插件创建自定义方法

My problem concerns the creation of a custom method within an action. I'm using Struts2 and REST Plugin in order to implement a RESTful WebService. My action class is the following:

public class SampleController implements ModelDriven<Object> {

private Sample sample = new Sample();
private Collection<Sample> list;
private int id;

public HttpHeaders create() {
    sdao.save(sample);
    return new DefaultHttpHeaders("create");
}   


public HttpHeaders destroy() {
    return new DefaultHttpHeaders("destroy");
}

public HttpHeaders show() {
    return new DefaultHttpHeaders("show").disableCaching();
}

public HttpHeaders update() {
    sdao.save(sample);
    return new DefaultHttpHeaders("update");
}

public HttpHeaders index() {
    list = sdao.findAll();
    return new DefaultHttpHeaders("index").disableCaching();
}

public Object getModel() {
    return (list != null ? list : sample);
}


public int getId() {
    return id;
}

public void setId(Integer id) {
    if (id != null) {
        this.sample = (Sample) sdao.findById(id);
    }
    this.id = id;
}

}

我可以通过 GET HTTP 方法正确访问资源.为了使用自定义方法，通过将参数传递给搜索资源来调用，即

public searchBySenderName(String senderName) {
    list.addAll(sdao.findBySenderName(senderName))
}
