将JSP文件移动到带条纹的WEB-INF目录时出错

Question

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，将显示welcome.jsp的内容。

但是，当我将welcome.jsp移至/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.

为了将JSP文件存储在WEB-INF目录中是否需要执行任何特殊配置？

Answer 1

我的理解如下：您的WelcomeActionBean不在包装中[[web，www，条纹，动作]），由NameBasedActionResolver自动读取（阅读javadoc），因此它实际上被映射到NameBasedActionResolver（如错误消息中所述）。

因此，当您请求/myapp/Welcome.action时，该URL上没有任何现有的/Welcome.action，解析器回退到ActionBean（再次请参见/welcome.jsp javadoc）。而且，当您将JSP移到NameBasedActionResolver下时，运气不佳，一切都会失败。

要解决此问题，请选择：

• 访问“权限”（在当前状态下）URL绑定，即NameBasedActionResolver

• 或者，如果您希望您的ActionBean通过约定绑定到/WEB-INF/jsp，请将其移动到/myapp/Welcome.action处理的包中，例如/Welcome.action：

  NameBasedActionResolver

• 或在操作中添加NameBasedActionResolver以显式配置绑定：

  action

Answer 2

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");
    }
}

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@UrlBinding或

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");
    }
}

文件。）

您需要将JSP文件移到WEB-INF之外。
