如何在Struts2中定义StreamResult的输出名称？

Question

伙计们,我无法在网上清楚地找到这些信息.我有一个动作,我正在生成一个文本文件,但总是作为"generatePDF.action"文件出现在客户端.我希望它显示为receipt.txt文件.

这是我的注释:

   @Action(value = "/generateTXT",
    results = {
        @Result(name = "ok", type = "stream",
        params = {"inputName", "inputStream",
                  "contentType", "application/octet-stream",
                  "contentDispostion", "attachment;filename=receipt.txt"})
    })

如果您正在使用约定插件,那么让我们使用以下代码进行"/ YourApplicationContext/stream/stream-test"下的参考运行,然后解析为"/YourApplicationContext/stream/document.txt":

package struts2.stream;

import com.opensymphony.xwork2.ActionSupport;
import java.io.InputStream;
import java.io.StringBufferInputStream;
import org.apache.struts2.convention.annotation.Result;


@Result(name = ActionSupport.SUCCESS, type = "stream", params =
{
    "contentType",
    "text/hmtl",
    "inputName",
    "inputStream",
    "contentDisposition",
    "filename=document.txt"
})
public class StreamTestAction extends ActionSupport{
    public InputStream inputStream;

    @Override
    public String execute(){
    inputStream = new StringBufferInputStream("Hello World! This is a text string response from a Struts 2 Action.");      
    return SUCCESS;
    }
}

请注意"contentDisposition"并将其值设置为"filename ='document.txt'"更改'document.txt'可以获得您想要的内容.
