条带不将事件与{$event}绑定

Question

我是stripes的新手，所以很抱歉，如果这是一个简单的问题，现在我有这个课程：

 ....
 import net.sourceforge.stripes.action.DefaultHandler;
 import net.sourceforge.stripes.action.DontValidate;
 import net.sourceforge.stripes.action.ForwardResolution;
 import net.sourceforge.stripes.action.HandlesEvent;
 import net.sourceforge.stripes.action.RedirectResolution;
 import net.sourceforge.stripes.action.Resolution;
 import net.sourceforge.stripes.action.UrlBinding;
 import net.sourceforge.stripes.integration.spring.SpringBean;
 import net.sourceforge.stripes.validation.ValidationMethod;
 import net.sourceforge.stripes.validation.ValidationState;

@UrlBinding("/role/{$event}")
public class RoleActionBean extends BaseActionBean {

    @DefaultHandler @DontValidate
    @HandlesEvent("add")
    public Resolution listrole() {
        ...
        return new ForwardResolution("/jsp/role/list.jsp");
    }

    @HandlesEvent("add") @DontValidate
    public Resolution addrole() {
        ...
        return new ForwardResolution("/jsp/role/add.jsp");
    }

    @HandlesEvent("save")
    public Resolution saverole() 
    {
        ...
    }

    @HandlesEvent("view") @DontValidate
    public Resolution viewrole() {
        ...
    }

    @HandlesEvent("edit") @DontValidate
    public Resolution editrole() {
        ...
    }

    @HandlesEvent("update")
    public Resolution updaterole() {
        ...
    }

    @HandlesEvent("delete")
    public Resolution deleterole() {
        ...
    }



    @ValidationMethod(on={"save", "update"}, when=ValidationState.ALWAYS)
    public void validarDatosrole(){
        ... 
    }


    @ValidationMethod(on={"save", "update"}, when=ValidationState.ALWAYS)
    public void validarDatosrole2(){
        ...
    }

    ...
}

但当我尝试访问url的ActionBean时：

/role/add

或者任何其他事件，我得到了404，我正在尝试获得更干净的URL，以便在我使用它之前，可以更容易地限制用户可以使用spring安全性的操作：

@UrlBinding("/role.html")

然后转到URL：

role.html?add

我不知道我做错了什么，请帮助我，提前谢谢。

我相信这是因为您对add事件有两个处理程序方法。这会导致条带无法启动，并出现以下异常(然后使用404响应所有请求，因为servlet无法启动)

Answer 2

dhensche是正确的，您在发布的代码中有太多的添加处理程序。

如果我们假设这只是一个复制错误，并且您的ActionBean在您的UrlBinding更改之前是可用的，我认为您可能想要查看您的servlet映射配置。

由于您的链接将不再包含".action"，web请求可能不知道如何到达StripesDispatcher，这就是为什么您将收到404响应。

这篇博客文章有一个你想要做的事情的详细例子：Clean and usable URLs in Stripes

此外，您可能想要考虑命名解析方法以匹配它们处理的事件，并丢弃HandlesEvent注释。那么就不可能意外地定义重复的处理程序。
