错误将JSP文件移至带有条纹的Web-Inf目录

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，显示欢迎的内容。

但是，当我移动欢迎。

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

加载 /myapp/welcome.action时，我会遇到以下错误：

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)

是否有必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

我的理解是：您 WelcomeActionBean 在不包装中（[Web，www，cripes，action]）自动处理 NameBasedActionResolver （阅读Javadoc），因此实际上映射到 /myapp/Welcome.action （如错误消息中所述）。

所以，当您要求 /Welcome.action, ，没有现有的 ActionBean 绑定到该URL和解析器的后备 /welcome.jsp （再次，请参阅 NameBasedActionResolver Javadoc）。当您将JSP移动到下面 /WEB-INF/jsp, ，好吧，您没运气，一切都失败了。

要解决这个问题：

• 访问“正确”（在当前状态）URL绑定IE /myapp/Welcome.action

• 或者，如果您希望您的动作限制 /Welcome.action 通过惯例，将其移至由 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");
      }
  }
  

• 或添加一个 @UrlBinding 要明确配置绑定的操作：

  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 是一个特殊的目录，客户无法访问其内容。 （这很有意义 - 您不希望客户能够下载您的 web.xml 或你的 .class 文件。）

您需要将JSP文件移到 WEB-INF.
