接口/枚举列出标准 mime 类型常量

我在标准库(如 apache commons、 jax、 jboss、 javax)中寻找列出所有标准 mime-type (即 content-type)值的接口或枚举。

这个接口不应该被太深的其他类所阻碍，因为这会使得将整个类包含为 gwt 源代码变得很困难。

比如说

interface ContentType{
String JSON = "Application/JSON";
blah ... blah ...
}

或者,

enum ContentType{
JSON("Application/JSON"),
blah ... blah ...
}

正如在前面的回答中所提到的，大多数常见的 MIME 类型都是在 webserver 中配置的。例如，在 tomcat conf/中，我们配置了 web.xml 和以下 MIME:

   <mime-mapping>
<extension>abs</extension>
<mime-type>audio/x-mpeg</mime-type>
</mime-mapping>
<mime-mapping>
<extension>ai</extension>
<mime-type>application/postscript</mime-type>
</mime-mapping>
<mime-mapping>
<extension>aif</extension>
<mime-type>audio/x-aiff</mime-type>
</mime-mapping>
...

创建一个启动监听器，它在 Web 应用启动时启动，并解析这个 XML 文件，为您创建 ENUMS，并将其绑定到 servlet 上下文，以便在下游共享。

我们有一个 番石榴类: com.google.common.net.MediaType。

它与番石榴12一起发布，如源代码和 第823期中所述。 消息来源也是可用的。

如果您使用的是 Spring 框架，那么对于常见的内容类型，有一个 MediaType类:

MediaType.TEXT_HTML
MediaType.TEXT_PLAIN
MediaType.TEXT_XML
MediaType.APPLICATION_JSON
MediaType.IMAGE_JPEG
...

JAX-RS呼叫 javax.ws.rs.core.MediaType

现在还有来自包 org.apache.httpcomponents.httpcore的类 org.apache.http.entity.ContentType，从4.2开始。

Java 7来救场了！

您可以传递文件或文件名，它将返回 MIME 类型。

String mimeType = MimetypesFileTypeMap
.getDefaultFileTypeMap()
.getContentType(attachment.getFileName());

在 机器人注释中还有一个 MediaType类，如果你想和 android 一起使用的话，请参阅 给你。

如果你使用的是机器人系统，你有多种选择，只有第一种是一种“枚举”:

比如说

@Override
public String getType(Uri uri) {
return URLConnection.getFileNameMap().getContentTypeFor(
uri.getLastPathSegment());
}

我用一个静态类解决了这个问题:

正如上面的答案所指出的，您可以使用具有所需常量的 javax.ws.rs.core.MediaType。

我还想分享一个非常酷和方便的链接，我发现它在一个地方提供了对所有 Javax 常量的引用-https://docs.oracle.com/javaee/7/api/constant-values.html。
