文件名和其文檔類型的對應規則，每個文件都有不一樣的文件後綴.txt , .html , .zip 他們的文檔類型是不一樣的。詳細請看 文件名和對應的ContentType 對應表 。
並且提供了一個java讀取這些屬性的代碼供參考。

定義
HTML中的ContentType
Content-Type，內容類型，一般是指網頁中存在的Content-Type，用於定義網絡文件的類型和網頁的編碼，決定瀏覽器將以什麼形式、什麼編碼讀取這個文件，這就是經常看到一些Asp網頁點擊的結果卻是下載到的一個文件或一張圖片的原因。
ASP中的ContentType
2語法規則編輯
GZIP中的 Content-Type=text/ht*/js/css/php
3語法編輯
HTML
Response.ContentType [= ContentType]
Java Servlet
response.setContentType(String);
4參數編輯
HTML
content
即爲類型，具體參照下文的“ContentType的類型”
charset
ContentType
示例
下面的示例將內容類型設置爲 Channel Definition Format（CDF）。
<% Response.ContentType = "application/x-cdf" %>
下面的示例將 ContentType 屬性設置爲其他的常見值。
<% Response.ContentType = "text/HTML" %>
<% Response.ContentType = "image/GIF" %>
<% Response.ContentType = "image/JPEG" %>
應用於
Response 對象
關於詳細的類型對應參看ContentType的類型。
存到contentType.proerties 文件中，再使用classLoad讀出來
java代碼訪問
/**
* 根據文件名獲取ContentType
* @param object 文件名
* @param pro contentType-file 對應的 Properties對象
* @return ContentType
*/
private String getContentType(String object,Properties pro) {
if(object.contains(".")){
int index = object.lastIndexOf(".");
String suffix = object.substring(index+1); //獲取文件後綴
Object contentType = pro.get(suffix);
if(contentType != null)
return contentType.toString();
}
return "text/html";
}
/**
* 載入ContentType 文件
* @return
*/
public Properties loadFileContentType(){
InputStream is = getClass().getClassLoader().getSystemResourceAsStream("contentType.proerties");
Properties pro = new Properties();
try {
pro.load(is);
} catch (IOException e) {
e.printStackTrace();
}
return pro;
}contentType.proerties
