JSF 渲染器 - 将编码输出存储在字符串中以便重新定位
我想将 UIComponent 的encodeAll() 方法生成的响应存储到字符串中，以便在其他地方使用该内容。
我已经尝试设置一个 FacesContextWrapper，它提供了一个特殊的 ResponseWriter，该 ResponseWriter 应该将内容写入 StringWriter，但它不起作用。看来我的 ResponseWriter 从未被调用过。
我知道还有其他方法并在正确的位置进行编码，也许我会这样做，但我仍然想知道如何做到这一点。尤其是内容的压缩，标签之间不能有空格，不能换行，非常重要。
编辑：
我有一些方面，这些内容用于传递给javascript，因此我需要将方面的渲染内容压缩到一行。 首先，我尝试围绕 writer 获取内容，然后自己压缩它并将其作为参数附加到 javascript 中，但它不起作用。 现在我将内容渲染在正确的位置，但它没有压缩为一行。
EDIT2：
如果在行末尾使用“\n\”，Javascript 字符串只能是多行的。我无法更改encodeAll() 方法生成的内容，所以这真的很难。我真的必须捕获生成的内容，然后手动压缩字符串！但如何做到这一点呢？ ResponseWriter 包装对我不起作用。
解决方案：
我想与其他人分享我的解决方案！ ResponseWriter 提供了一个名为 cloneWithWriter(Writer w) 的方法，我不知道。通过将此方法与自定义 StringWriter 实现结合使用，您可以捕获缓冲区中的输出，并最终将该缓冲区用作字符串
I would like to store the response generated by the encodeAll() method of a UIComponent into a string to use the content somewhere else.
I alread tried to set up a FacesContextWrapper which provides a special ResponseWriter that should write the content to a StringWriter, but it does not work. It seems my ResponseWriter is never called.
I know there is the other way and encode in the right place and probably I will do so, but I would still like to know how to do that. Especially the compression of the content, there should be no spaces between tags and no linebreaks, is very important.
EDIT:
I have some facets and the content of these is used to be passed to javascript, because of that i would need the rendered content of the facets to be compressed to a single line.
First i tried to wrap around the writer to get the content, then compress it myself and append it to the javascript as parameter, but it didn't work.
Now i render the content at the right place, but it's not compressed to a single line.
EDIT2:
Javascript Strings can only be multilined if "\n\" is used at the end of the line. I can't change the content produced by the encodeAll() method so it's really hard. I really will have to capture the content that is generated and then manually compress the string! But how to do that? ResponseWriter-wrapping did not work for me.
SOLUTION:
I would like to share my solution with others!
ResponseWriter offers a method called cloneWithWriter(Writer w) which i didn't know. By using this method with a custom StringWriter implementation you can capture the output in a buffer and finally use that buffer as string
