只是想知道幕后是什么。实际上,我们似乎可以使用以下方式设置编码:

  • response.setContentType("text/html; charset=UTF-8")
  • response.setCharacterEncoding("UTF-8")

有什么区别?

最佳答案

javadoc很清楚区别:

void setCharacterEncoding(String charset) Sets the character encoding (MIME charset) of the response being sent to the client, for example, to UTF-8. If the character encoding has already been set by setContentType(java.lang.String) or setLocale(java.util.Locale), this method overrides it. Calling setContentType(java.lang.String) with the String of text/html and calling this method with the String of UTF-8 is equivalent with calling setContentType with the String of text/html; charset=UTF-8.


void setContentType(String type) 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.
