可以在struts2-core-{version}.jar中找到struts-default.xml，里面列舉了當前可以使用的所有result-type以及對應的class

此處是struts2.2.3的

1.chain

該類型是請求轉發給其他的action，如果為jsp則會報錯

需要注意的就是與redirect的區別，請求轉發是還在當前請求，

而redirect會響應一次瀏覽器然后瀏覽器再根據響應請求重定向的資源，注意看url的變化就明白了！

下面是apache給的示例，這個比較簡單，沒什么說的，

重定向操作，與請求轉發的區別看1的介紹

讓客戶端請求另外的網絡資源，可以為action，也可以為視圖資源

下面是apache的示例

[html]?view plaincopyprint?

<result?name="success"?type="redirect">??

??<param?name="location">foo.jsp</param>??

??<param?name="parse">false</param>??

</result>??

5.redirectAction

重定向至Action，與redirect的區別找了好久，但是也沒發現比較權威的說明

最明顯的區別當然是redirectAction只能請求action,如果請求視圖資源會報錯

然后還有個小區別就是redirectAction會為url添加.action后綴而redirect不會

有說redirectAction無法通過url傳參，但是我測試時完全可以通過request獲取到，

此處區別如果有哪位知道的麻煩告知，Thank you!

下面是apache的傳參的示例

[html]?view plaincopyprint?

<package?name="passingRequestParameters"?extends="struts-default"?namespace="/passingRequestParameters">??

???<--?Pass?parameters?(reportType,?width?and?height)?-->??

???<!--??

???The?redirect-action?url?generated?will?be?:??

???/genReport/generateReport.action?reportType=pie&width=100&height=100??

???-->??

???<action?name="gatherReportInfo"?class="...">??

??????<result?name="showReportResult"?type="redirect-action">??

?????????<param?name="actionName">generateReport</param>??

?????????<param?name="namespace">/genReport</param>??

?????????<param?name="reportType">pie</param>??

?????????<param?name="width">100</param>??

?????????<param?name="height">100</param>??

??????</result>??

???</action>??

</package>??

6.stream

這個返回類型主要用作下載文件或者在瀏覽器上顯示PDF等文檔

此處給一個顯示PDF文檔示例

項目web.xml中

[html]?view plaincopyprint?

<mime-mapping>????

??????<extension>pdf</extension>????

??????<mime-type>application/pdf</mime-type>????

??</mime-mapping>????

struts.xml中

[html]?view plaincopyprint?

<action?name="test"?class="com.iss.action.TestAction">??

????????????<result?name="success"?type="stream">??

????????????????<param?name="contentType">application/pdf</param>??

????????????????<param?name="inputName">inputStream</param>??

????????????????<param?name="contentDisposition">filename="a.pdf"</param>??

????????????</result>??

????????</action>??

TestAction.java中

[java]?view plaincopyprint?

public?class?TestAction?extends?ActionSupport??

{??

??????

????private?InputStream?inputStream;??

??

??

????public?InputStream?getInputStream()??

????{??

????????return?inputStream;??

????}??

??

????@Override??

????public?String?execute()?throws?Exception??

????{??

????????inputStream?=?new?FileInputStream("xxxxx/a.pdf");//要下載或顯示的文件路徑??

????????return?SUCCESS;??

????}??

}??

需要注意的地方是struts.xml中inputName的值要與TestAction中的get方法名相關，如在此處是getInputStream，inputName則為inputStream

7.plainText

響應以plain形式返回給客戶端

截取源碼的最重要的一部分

[java]?view plaincopyprint?

if?(charset?!=?null)?{??

???????????response.setContentType("text/plain;?charset="+charSet);??

???????}??

???????else?{??

???????????response.setContentType("text/plain");??

???????}??

8.freemarker,velocity,xslt

沒有嘗試過，有興趣的可以嘗試下

寫得很累。。。
