response.setContentType(MIME)的作用是使客户端浏览器，区分不同种类的数据，并根据不同的MIME调用浏览器内不同的程序嵌入模块来处理相应的数据。

例如web浏览器就是通过MIME类型来判断文件是GIF图片。通过MIME类型来处理json字符串。
Tomcat的安装目录\conf\web.xml 中就定义了大量MIME类型 ，可以参考。
response.setContentType("text/html; charset=utf-8"); html
.setContentType("text/plain; charset=utf-8"); 文本
text/javascript json数据
application/xml xml数据

这
个方法设置发送到客户端的响应的内容类型，此时响应还没有提交。给出的内容类型可以包括字符编码说明，例
如：text/html;charset=UTF-8.如果该方法在getWriter()方法被调用之前调用，那么响应的字符编码将仅从给出的内容类型
中设置。该方法如果在getWriter()方法被调用之后或者在被提交之后调用，将不会设置响应的字符编码，在使用http协议的情况中，该方法设置
Content-type实体报头。

一般在Servlet中，习惯性的会首先设置请求以及响应的内容类型以及编码方式：

复制代码 代码如下:
response.setContentType("text/html;charset=UTF-8");
request.setCharacterEncoding("UTF-8");
response.setContentType()的String参数及对应类型
<option value="image/bmp">BMP</option>
<option value="image/gif">GIF</option>
<option value="image/jpeg">JPEG</option>
<option value="image/tiff">TIFF</option>
<option value="image/x-dcx">DCX</option>

<option value="text/html">HTML</option>

<option value="text/xml">XML</option>
<option value="application/afp">AFP</option>
<option value="application/pdf">PDF</option>
<option value="application/rtf">RTF</option>
<option value="application/msword">MSWORD</option>
<option value="application/vnd.ms-excel">MSEXCEL</option>
<option value="application/vnd.ms-powerpoint">MSPOWERPOINT</option>
<option value="application/wordperfect5.1">WORDPERFECT</option>
<option value="application/vnd.lotus-wordpro">WORDPRO</option>
<option value="application/vnd.visio">VISIO</option>
<option value="application/vnd.framemaker">FRAMEMAKER</option>
<option value="application/vnd.lotus-1-2-3">LOTUS123</option>

MIME
映射策略就是在网页中使用哪个应用程序（即插件），打开哪种文件。另外还有使用权限问题。比如对PDF文档，用“application/pdf
“策略。这在动态网页中很常见。出现这种现象，有两种情形：一是使用一个应用程序去打开它不能打开的文档，比如用在标签中定义“DWG”文档用
“application/pdf
”，就会出现无法打开的问题。二是文件扩展名符合要求，但文件内容（格式）不符合要求。你可以检查你浏览的网页源代码，获得出错信息。检查方法是：查看—
源文件。寻找类似于“application/pdf “的字符串，就可以看到，要打开的文件是否与应用程序匹配。 追问
如果不相匹配如何解决回答这通常是由网页编写人来更改。比如：你在源文件里面找到你要打开的文件的HTML标签，在里面加上应用程序即可。比如，你要在网
页上打开一个PDF文档，找到PDF文档那一行，在HTML标签里加上 type=“application/pdf “
就可以了。比如以下HTML文件： <!----------测试MIME-----------><html>
<head><title>测试MIME</title></head><body>
<a type="application/pdf" href="test.pdf">测试MIME</a>
</body> </html
将上面的代码保存为test.html，再在相同的位置存储一个pdf文档，双击它就会在网页中打开该文档。
