First, Docker pulls the Tomcat image, as shown in figure:
Second, install the Tomcat container, as shown:
Note:--link Connect to MySQL (otherwise the DB cannot be accessed.) Each container is independent)
Tomcat_mysql is an alias. DB configured as: tomcat_mysql:3306
Third, if the 80 port is occupied, then stop Tomcat and remove the Tomcat container, as shown in figure:
Four, replace the port of
If we use Dockerfile to build Docker mirrors, it would be very scary to accidentally cause the mirror to be larger than 1G. Are generally good hundreds of trillion. Larger mirrors tend to cause porting and migration is slow. Dockerfile, like code, needs to be optimized continuously. Using the following 4 optimization schemes, you can significantly reduce the size of the mirror.
The most important factor is to reduce the number of mirrored layers, whic

However, no shortcut menu for copying image link addresses is available in IE, myie, sogou, and other browsers that share the right-click menu with IE. Generally, only the image attributes are selected and then the image address is copied in the Properties dialog box, very troublesome!
Next we will add a shortcut menu for "co
The Assembly in the application domain can be updated without uninstalling the application domain through image replication. This is especially useful for applications that must be used continuously (such as ASP. NET websites.
When the Assembly is loaded, the common language runtime locks the Assembly file, so the file can be updated only after the Assembly is uninstalled. The only way to detach an assembly from an application domain is to detach the

What do you mean to create a copy of a picture? Because the images we take directly from the bitmapfactory are readable and cannot be modified. If the user wants to modify this image, it is generally based on the original image in memory and the original picture of the same size, and then modify the above, the user feels as if it was modified on the original, it

This function has been studied for a long time. It is easy to use ActiveX plug-ins written in C #. The server can also directly write data to folders, however, the client must install the framework, which is unrealistic for the customer.
Later, I studied how to use C ++ to implement ActiveX, upload post files to the server URL, and then accept post files. I was not familiar with C ++ for a long time, maybe I still don't use C ++, but Google and Baidu haven't found the correct solution.
Finally,
During image processing, we often need to process one or more areas of interest in the image. In opencv, we can easily obtain sub-images in the specified ROI Area. The following code demonstrates how to obtain a single ROI or multiple ROI image regions.
