Spring MVC 3 Return内容类型：文本/纯文本 [英] Spring MVC 3 Return Content-Type: text/plain

问题描述

我想在页面上显示简单文本，因此我想将 Content-Type 返回为 text / plain 。

I want to display simple text on a page and as such I want to return the Content-Type as text/plain.

使用下面的代码，我在页​​面上看到纯文本，但是返回 Content-Type 仍然是 text / html 。

Using the code below, I see plain text on the page, however the return Content-Type is still text/html.

我该如何解决？

注意：我正在使用带有Spring MVC的Tiles。返回的 m.health指向图块def，该图块def映射到仅包含下面1行的health.jsp。

NOTE: I'm using Tiles with Spring MVC. The returned "m.health" points to a tiles def that maps to a health.jsp which only contains the 1 line below.

更新说明 >：我无法控制HTTP标头请求中的 Content-Type 或 Accept 值。不管收到什么样的请求，我都希望我的响应返回 text / plain 。

UPDATE NOTE: I have no control over the Content-Type or Accept values in the HTTP Header request. I want my response to return text/plain no matter what kind of request comes in.

Controller：

Controller:

@RequestMapping(value = "/m/health", method = RequestMethod.GET, headers = "Accept=*")
public String runHealthCheck(HttpServletResponse response, HttpServletRequest request, Model model) throws Exception {
    model = executeCheck(request, response, TEMPLATE, false, model);
    model.addAttribute("accept", "text/plain");
    response.setContentType("text/plain");
    response.setCharacterEncoding("UTF-8");
    return "m.health";
}

JSP：

$ {状态}

${status}

推荐答案

如果您使用@ResponseBody附加注释您的方法：

It should work if you annotate your method additionally with @ResponseBody:

@RequestMapping(value = "/",
                method = RequestMethod.GET)
@ResponseBody
public String plaintext(HttpServletResponse response) {
    response.setContentType("text/plain");
    response.setCharacterEncoding("UTF-8");
    return "TEXT";
}
