Java Web Implementation reads the image under the specified drive letter (ii)

Previously wrote an article on how to read the image under the specified drive letter, although the function can be implemented, but the use of the I/O flow, the efficiency is not high. Now there is a better way to use and more convenient.

We know that when our images are placed under Tomcat under WebApps's app directory, using src= "127.0.1:8080/xx/123.png" This way you can access the images. So if we can use the specified folder as a Tomcat workspace, then we can access the image directly.

All we need to do is add in Tomcat's Conf->server.xml host:

<context path= "/img" docbase= "H:/kk"         debug= "0" reloadable= "false" crosscontext= "false" verbosity= " DEBUG >     </Context>

Where path is the virtual path, Docbase is the specified folder.

We put 123.png images in the H:/KK, we can access our images in the browser input 127.0.0.1:8080/img/123.png.
