我想暗潮服务像为.jpg，.png，.js文件，名为.css，.TXT等静态文件...
我编辑在standalone.xml暗流子系统：
<subsystem xmlns="urn:jboss:domain:undertow:4.0">
<buffer-cache name="default"/>
<server name="default-server">
<http-listener name="default" socket-binding="http" redirect-socket="https" enable-http2="true"/>
<https-listener name="https" socket-binding="https" security-realm="ApplicationRealm" enable-http2="true"/>
<host name="default-host" alias="localhost">
<location name="/images" handler="sh-resources"/>
<filter-ref name="server-header"/>
<filter-ref name="x-powered-by-header"/>
<filter-ref name="content-png" predicate="path-suffix['.png']"/>
<http-invoker security-realm="ApplicationRealm"/>
</host>
</server>
<servlet-container name="default">
<jsp-config/>
<websockets/>
</servlet-container>
<handlers>
<file name="sh-resources" path="/resource" directory-listing="true"/>
</handlers>
<filters>
<response-header name="server-header" header-name="Server" header-value="WildFly/11"/>
<response-header name="x-powered-by-header" header-name="X-Powered-By" header-value="Undertow/1"/>
<response-header name="content-png" header-name="Content-Type" header-value="image/png"/>
</filters>
</subsystem>
我甲肝在我的“/资源”文件夹“1.JPG”中，“2.png”，“js.js”，“c.css”一些文件：
HTTP：//本地主机：8080 /资源/ 1.JPG - >显示什么浏览器
HTTP：//本地主机：8080 /资源/ 2.png - >显示什么浏览器
HTTP：//本地主机：8080 /资源/ js.js - >显示什么浏览器
HTTP：//本地主机：8080 /资源/ c.css - >显示文件浏览器内容
HTTP：//本地主机：8080 /资源/ test.html文件 - >显示文件浏览器内容
为什么不能我看到的图像，但可以看到的CSS和HTML内容？ 我认为它是因为不正确的MIME类型设置？
PS：我想通过一个Servlet服务于静态文件和设置正确的MIME类型 - >一切完美的浏览器（Chrome），我可以看到的图像和.js文件的内容（和所有其他的文件结尾）。
我的servlet代码（应用程序正在运行，在“/”服务器的）：
@WebFilter("/*") //get all requests
public class MasterFilter implements javax.servlet.Filter {
//...
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
String path = req.getRequestURI();
if (path.startsWith("/resource")) {
String mimetype = "text/html;charset=UTF-8";
mimetype = path.contains(".png") ? "image/png" : mimetype;
mimetype = path.contains(".jpg") || path.contains(".jpeg") ? "image/jpeg" : mimetype;
mimetype = path.contains(".js") ? "text/javascript" : mimetype;
mimetype = path.contains(".css") ? "text/css" : mimetype;
response.setContentType(mimetype);
chain.doFilter(request, response); // Goes to static resource in local folder "webapp/resource/"
}
}
有什么建议么 ？ 提前致谢。
编辑：
与Servlet过滤器的上述解决方案正常工作。 但由于@ JGlass的答案，我还发现了另一种解决方案。 （记住，我绝对需要我的Servlet过滤器）：
“MasterFilter” 级转发给 “的serveResource” 的servlet：
@WebFilter("/*") public class MasterFilter implements javax.servlet.Filter { /*...*/ public void doFilter(..){ /*...*/ if (path.startsWith("/resource")) {//forward to "ServeResource" servlet } } }
2. “的serveResource” 的servlet提供静态文件：
@WebServlet("/resource/*")
public class ServeResource extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public ServeResource() {
super();
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
response)
*/
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
ServletContext cntx= req.getServletContext();
String fileUri = req.getRequestURI();
System.out.println("fileUri: "+fileUri);
// Get the absolute path of the image (or any file)
String filename = cntx.getRealPath(fileUri);
System.out.println("file realPath: "+filename);
// retrieve mimeType dynamically
String mime = cntx.getMimeType(filename);
System.out.println("mime type: "+mime);
if (mime == null) {
resp.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
return;
}
resp.setContentType(mime);
File file = new File(filename);
resp.setContentLength((int)file.length());
FileInputStream in = new FileInputStream(file);
OutputStream out = resp.getOutputStream();
// Copy the contents of the file to the output stream
byte[] buf = new byte[1024];
int count = 0;
while ((count = in.read(buf)) >= 0) {
out.write(buf, 0, count);
}
out.close();
in.close();
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request, response);
}
}
3.web.xml包含扩展名映射：
<mime-mapping>
<extension>html</extension>
<mime-type>text/html</mime-type>
</mime-mapping>
<mime-mapping>
<extension>txt</extension>
<mime-type>text/plain</mime-type>
</mime-mapping>
<mime-mapping>
<extension>js</extension>
<mime-type>text/javascript</mime-type>
</mime-mapping>
<mime-mapping>
<extension>jpg</extension>
<mime-type>image/jpeg</mime-type>
</mime-mapping>
<mime-mapping>
<extension>jpeg</extension>
<mime-type>image/jpeg</mime-type>
</mime-mapping>
<mime-mapping>
<extension>png</extension>
<mime-type>image/png</mime-type>
</mime-mapping>
<mime-mapping>
<extension>css</extension>
<mime-type>text/css</mime-type>
</mime-mapping>
<mime-mapping>
<extension>zip</extension>
<mime-type>application/zip</mime-type>
</mime-mapping>
