我有以下条纹 ActionBean：

package myapp;

import net.sourceforge.stripes.action.*;

public class WelcomeActionBean extends MyAppActionBean {
    @DefaultHandler
    public Resolution view() {
        return new ForwardResolution("/welcome.jsp");
    }
}

当我在浏览器中加载 /myapp/Welcome.action 时，会显示welcome.jsp 的内容。

但是，当我将 welcome.jsp 移动到 /WEB-INF/jsp/welcome.jsp 并更改 ForwardResolution 参数以反映该更改时，即：

return new ForwardResolution("/WEB-INF/jsp/welcome.jsp");

加载 /myapp/Welcome.action 时出现以下错误：

net.sourceforge.stripes.exception.ActionBeanNotFoundException: Could not locate an ActionBean that is bound to the URL [/Welcome.action]. Commons reasons for this include mis-matched URLs and forgetting to implement ActionBean in your class. Registered ActionBeans are: {/controller/DefaultView.action=class net.sourceforge.stripes.controller.DefaultViewActionBean, /myapp/MyApp.action/=class myapp.MyAppActionBean, /myapp/Welcome.action/=class myapp.WelcomeActionBean, /controller/DefaultView.action/=class net.sourceforge.stripes.controller.DefaultViewActionBean, /myapp/MyApp.action=class myapp.MyAppActionBean, /myapp/Welcome.action=class myapp.WelcomeActionBean}

    javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
    net.sourceforge.stripes.controller.StripesFilter.doFilter(StripesFilter.java:247)

是否需要执行任何特殊配置才能将 JSP 文件存储在 WEB-INF 目录中？

我的理解如下：您WelcomeActionBean不在包中（[web，www，stripes，action]）由NameBasedActionResolver（阅读javadoc）自动处理，因此它实际上被映射到/myapp/Welcome.action（如错误消息中所述）。

因此，当您请求时/Welcome.action，该 URL 没有任何现有ActionBean绑定，并且解析器回退到/welcome.jsp（再次参见 NameBasedActionResolverjavadoc）。当您将 JSP 移到 . 下/WEB-INF/jsp时，您运气不佳，一切都失败了。

为了解决这个问题，要么：

  • 访问“正确”（在当前状态下）的 URL 绑定，即/myapp/Welcome.action

  • 或者，如果您希望 ActionBean 受/Welcome.action约定约束，请将其移动到由 处理的包中NameBasedActionResolver，例如action：

    package myapp.action;

import net.sourceforge.stripes.action.*;

public class WelcomeActionBean extends MyAppActionBean {
    @DefaultHandler
    public Resolution view() {
        return new ForwardResolution("/WEB-INF/jsp/welcome.jsp");
    }
}

  • 或者在@UrlBinding您的操作中添加一个以显式配置绑定：

    package myapp;

import net.sourceforge.stripes.action.*;

@UrlBinding("/Welcome.action")
public class WelcomeActionBean extends MyAppActionBean {
    @DefaultHandler
    public Resolution view() {
        return new ForwardResolution("/WEB-INF/jsp/welcome.jsp");
    }
}

WEB-INF是一个特殊目录，客户端无法访问其内容。（这是有道理的——您不希望客户端能够下载您web.xml或您的.class文件。）

您需要将 JSP 文件移到WEB-INF.
