在setText（Java邮件）中发送文件内容

我有一个jsp文件：

email.jsp

<div id="foo">
    <span id="bar">test</span>
</div>

将导致如下结果：

email.setText("<div id="foo"><span id="bar">test</span></div>");

email.setText（“测试”）；

我如何才能做到这一点？

您可以编写一个实用方法：

 /**
 * @param fileName String: Path of the JSP file 
 * @return jspContent String : contents of the JSP file
 * @throws IOException
 */
private String readJSPContents(String fileName) throws IOException {
    InputStream io = getServletContext().getResourceAsStream(fileName);
    BufferedReader in = new BufferedReader(new InputStreamReader(io));
    String str;
    String jspContent = "";
    while ((str = in.readLine()) != null)
        jspContent+=str;
    in.close();
    return jspContent;
}

然后，

email.setText（readJSPContents（“email.jsp”），“utf-8”，“html”）

 /**
 * @param fileName String: Path of the JSP file 
 * @return jspContent String : contents of the JSP file
 * @throws IOException
 */
private String readJSPContents(String fileName) throws IOException {
    InputStream io = getServletContext().getResourceAsStream(fileName);
    BufferedReader in = new BufferedReader(new InputStreamReader(io));
    String str;
    String jspContent = "";
    while ((str = in.readLine()) != null)
        jspContent+=str;
    in.close();
    return jspContent;
}
