This method considers only response headers set or added via setHeader(java.lang.String, java.lang.String), addHeader(java.lang.String, java.lang.String), setDateHeader(java.lang.String, long), addDateHeader(java.lang.String, long), setIntHeader(java.lang.String, int), or addIntHeader(java.lang.String, int), respectively.
此方法仅考虑通过 setHeader(java.lang.String, java.lang.String), addHeader(java.lang.String, java.lang.String), setDateHeader(java.lang.String, long) 设置或添加的响应头、addDateHeader(java.lang.String, long)、setIntHeader(java.lang.String, int) 或 addIntHeader(java.lang.String, int) 分别。

HttpServletResponse#getHeaders(java.lang.String)returns you a list of all headers for that string value
HttpServletResponse#getHeaders(java.lang.String)返回该字符串值的所有标头的列表
回答by yunus kula
HttpServletResponse.getHeader("key") returns first value
HttpServletResponse.getHeader("key") 返回第一个值
HttpServletResponse.getHeaders("key) return all values belonging to this key.
HttpServletResponse.getHeaders("key) 返回属于该键的所有值。
