Spring MVC - 包含呈现的 JSP 视图的 AJAX-JSON 响应 [英] Spring MVC - AJAX-JSON Response to contain rendered JSP view
问题描述
我需要我的控制器返回一个包含更新的 HTML 代码的 AJAX JSON 响应.
I need my controller to return an AJAX JSON response that contains the updated HTML code.
更新后的 HTML 代码是通过呈现 JSP 视图创建的.
The updated HTML code is created by rendering a JSP view.
例如:JSP:
<tr>
<td>${data1}</td>
<td>${data2}</td>
</tr>
JSON 响应:
{"columns" : "2", "rows":"1", "data":rendered view}
目前我正在尝试使用我自己的"输出流创建一个虚拟响应，并将渲染的视图内容放入 json 响应中，但没有成功.
Currently I'm trying to create a dummy response with "my own" outputstream and put the rendered view content in the json response, but with no luck.
除了我无法让这个解决方案发挥作用之外，感觉不太对.有关正确操作方法的任何提示?
Other than the fact I can't get this solution to work, it doesn't feel right. Any tips on the proper way to do it?
谢谢，奥利
推荐答案
如果要捕获的视图在 /WEB-INF/views/my.jsp 中，则调用
If the view you want to capture is in /WEB-INF/views/my.jsp, then call
request.getRequestDispatcher("/WEB-INF/views/my.jsp").include(request, myResponse);
其中 myResponse 是您创建的 HttpServletResponseWrapper 或 Spring MockHttpServletResponse.在后一种情况下，您可以从 getContentAsString() 获取渲染输出.
where myResponse is either a HttpServletResponseWrapper that you've created, or a Spring MockHttpServletResponse. In the latter case you can get the rendered output from getContentAsString().
在下面编辑
我遇到了另一个关于捕获 servlet 响应的 SO 问题有一些指向您可以使用的 HttpServletResponseWrappers 的指针.
I ran into another SO question around capturing servlet responses that had some pointers to HttpServletResponseWrappers that you can use.
两个看起来不错的实现:
Two implementations that look good:
- DWR SwallowingHttpServletResponse
- Sitemesh PageResponseWrapper
