我收到的响应的标题为:
Content-Length:18588
Content-Type:application/json;charset=UTF-8
Date:Wed, 02 Dec 2015 12:58:51 GMT
Server:Apache-Coyote/1.1
是否有可能在将“application/json”编码字符串发送到 View 之前将其更改为“text/plain;charset=ISO-8859-1”编码？我正在使用 Spring MVC。 任何帮助将不胜感激。
最佳答案
您的要求是在将响应发送回客户端之前设置所需的内容类型，因此请使用httpServletResponse.setContentType("text/plain;charset=ISO-8859-1");
这是来自 javax.servlet.ServletResponse(setContentType(java.lang.String type) 的方法
以下摘录自文档。
Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/html;charset=UTF-8. The response's character encoding is only set from the given content type if this method is called before getWriter is called.
This method may be called repeatedly to change content type and character encoding. This method has no effect if called after the response has been committed. It does not set the response's character encoding if it is called after getWriter has been called or after the response has been committed.
Containers must communicate the content type and the character encoding used for the servlet response's writer to the client if the protocol provides a way for doing so. In the case of HTTP, the Content-Type header is used.
请注意:您应该在将响应提交回客户端之前使用此方法。从上面的摘录中可以看到这一点 - “如果在提交响应后调用此方法则无效。如果在调用 getWriter 或在提交响应后调用该方法，则它不会设置响应的字符编码。"
附注:
- 为了使您的应用程序更具可扩展性，即将来支持更多语言的可能性，请使用“UTF-8”编码方案。
