Struts2 返回一个为字符串的response

有些时候我们只想做个简单的ajax测试，但是又不想写serverlet就用struts2，这时候就需要返回一个简单的response就可以了。

package actions;

import java.io.InputStream;
import java.io.StringBufferInputStream;

import com.opensymphony.xwork2.ActionSupport;

public class TextResultAction extends ActionSupport {
<wbr><wbr><wbr> privateInputStream inputStream;</wbr></wbr></wbr>

<wbr><wbr><wbr> publicInputStream getInputStream() {<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr>return inputStream;<br><wbr><wbr><wbr> }</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr> publicvoid setInputStream(InputStream inputStream) {<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr>this.inputStream = inputStream;<br><wbr><wbr><wbr> }</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

<wbr><wbr><wbr> publicString execute() throws Exception {<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr>inputStream = new StringBufferInputStream(<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>"Hello World! This is a text string response from a Struts 2Action.");<br><wbr><wbr><wbr><wbr><wbr><wbr><wbr>return SUCCESS;<br><wbr><wbr><wbr> }<br> }</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>

struts中的配置

<action name="text-result" class="actions.TextResultAction">
<wbr> &lt;result type=<span class="code-quote">"stream"</span>&gt;<br><wbr><wbr><wbr><wbr>&lt;param name=<span class="code-quote">"contentType"</span>&gt;text/html&lt;/param&gt;<br><wbr><wbr><wbr><wbr>&lt;param name=<span class="code-quote">"inputName"</span>&gt;inputStream&lt;/param&gt;<br><wbr><wbr>&lt;/result&gt;<br> &lt;/action&gt;</wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
