接口/枚举列出标准的mime类型常量

时间:2011-10-21 20:25:45

标签: java gwt mime-types content-type guava

我正在查看标准库(如apache commons,jax,jboss,javax)中的接口或枚举列出了所有标准mime类型(也就是内容类型)的值。

这个界面不应该与其他类太深,因为很难将整个群体包含为gwt源代码。

例如

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

,或者

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

我们有一个 Guava 类:com.google.common.net.MediaType

它与源代码和Issue 823中所述的Guava 12一起发布。 Sources也可用。

如果您使用的是Spring Framework,则常见内容类型有MediaType个类:

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

Java 7救援!

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());

如果你在Android上有多种选择,只有第一种是" enum":

例如

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

正如上面的答案所指出的,你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且方便的链接,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

我用静态类解决了这个问题:

@SuppressWarnings("serial")
public class MimeTypes {

    private static final HashMap<String, String> mimeTypes;

    static {
        mimeTypes = new HashMap<String, String>() {

答案 9 :(得分:-3)

如前面的答案中所述,大多数常见的MIME类型都是在Web服务器中配置的。例如,在tomcat conf /中我们有web.xml,其中配置了以下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>
...

创建启动Web应用程序时启动的启动侦听器,并解析此XML文件并为您创建ENUMS并将其绑定到servlet上下文以便共享下游。
