Question

我有以下Stripes 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}

    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？

Answer 1

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

因此，当您请求/Welcome.action时，没有任何现有的ActionBean绑定到该网址，并且解析程序会回退到/welcome.jsp（再次参见NameBasedActionResolver javadoc ）。当你在/WEB-INF/jsp下移动你的JSP时，你运气不好，一切都失败了。

要解决此问题，请：

访问“权限”（在当前状态下）网址绑定，即/myapp/Welcome.action

或者，如果您希望ActionBean通过约定绑定到/Welcome.action，请将其移至NameBasedActionResolver处理的包中，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");
    }
}

或者在您的操作中添加@UrlBinding以明确配置绑定：

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");
    }
}

Answer 2

WEB-INF是一个特殊目录，客户端无法访问其内容。（这很有意义 - 您不希望客户端能够下载您的web.xml或您的.class文件。）

您需要将JSP文件移到WEB-INF之外。

使用Stripes将JSP文件移动到WEB-INF目录时出错
