Question

我是Struts2的新手，刚刚完成了一个无动作映射的问题，我的动作new将会执行，但是当它返回JSP时，总会有 404 。试图设置名称空间和结果如下，但仍然没有让它工作。

struts.xml中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>

  <constant name="struts.devMode" value="true" />
  <constant name="struts.convention.result.path" value="/WebContent/jsp/" />

  <package name="default" extends="json-default">
    <action name="testAction" class="tw.com.rrstudio.java.test.TestAction" method="execute">
      <result name="login">index.jsp</result>
      <result name="success">TestAction.jsp</result>
    </action>
  </package>

</struts>

还尝试删除约定结果路径并将结果设置为此

<package name="default" extends="json-default">
  <action name="testAction" class="tw.com.rrstudio.java.test.TestAction" method="execute">
    <result name="login">/jsp/index.jsp</result>
    <result name="success">/jsp/TestAction.jsp</result>
  </action>
</package>

但仍然给出404。

的web.xml

    <url-pattern>/*</url-pattern>
  </servlet-mapping>

  <session-config>
    <session-timeout>10</session-timeout>
  </session-config>

</web-app>

我的动作java代码

package tw.com.rrstudio.java.test;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.interceptor.ServletRequestAware;
import com.opensymphony.xwork2.ActionSupport;

public class TestAction extends ActionSupport implements ServletRequestAware
{
  private static final long serialVersionUID=1L;
  public HttpServletRequest request;
  private String name="";

  public String execute() throws Exception
  {
    System.out.println("Debug: name="+name);
    System.out.println("Debug: path="+request.getContextPath());
    System.out.println("Debug: path="+request.getServletContext().getRealPath("/"));
    if(name!=null && !"".equals(name))
    {return "success";}
    else
    {return "login";}
  }

  @Override
  public void setServletRequest(HttpServletRequest request)
  {this.request=request;}

  public String getName()
  {return name;}

  public void setName(String name)
  {this.name=name;}
}

当我调用我的动作时，它会打印这样的调试消息，

http://127.0.0.1:8080/Struts2Test/testAction.action

调试：name =

Debug：path = / Struts2Test

Debug：path = D：\ eclipse \ workspace2.metadata.plugins \ org.eclipse.wst.server.core \ tmp0 \ wtpwebapps \ Struts2Test \
http://127.0.0.1:8080/Struts2Test/testAction.action?name=XYZ

调试：name = XYZ

Debug：path = / Struts2Test

Debug：path = D：\ eclipse \ workspace2.metadata.plugins \ org.eclipse.wst.server.core \ tmp0 \ wtpwebapps \ Struts2Test \

但总是给我404页面，没有任何消息。

HTTP Status 404 - 

type Status report
message 
description The requested resource is not available.

BTW，这是我的包结构。

  +Struts2Test/src

请提供任何建议或建议，感谢您的帮助。
