In back-end development, applications may have different configurations in different environments, such as database connections, log levels, etc., development, testing, and production each environment may not be configured in a consistent configuration.
With spring boot profile, configuration switching can be implemented in multiple scenarios to facilitate testing and deployment of production environments in development. Here's a general introduction to how the Yml configuration file and the pro

Recently, in the process of working, there is a need to manage the geoserver in an external program and find out that GeoServer's rest interface can meet the requirements by looking up data. The rest interface uses HTTP calls so that GeoServer can be simply invoked and configured without having to log on to the Web management interface.
GeoServer's website provides an introduction to rest's configuration APIs and examples at the address: http://docs.geoserver.org/stable/en/user/rest/index.html

different tests, enter a valid or invalid password (4 digits). However, each valid or invalid password will only detect one different error mode, for example, a system that uses 8080 as a valid password will not accept the illegal password 1234. If 1234 is accepted, an error will be generated. The input of another test is 1235, which is the same as the test intent of 1234, therefore, it is redundant. However, illegal input of 8081 or 8180 is slightly

Use two instances for demonstration.
1. There is a project that references WebService because it is sent to several servers at the same time. To facilitate switching, I need to be able to dynamically change its IP address (only the IP address is different, it is not different from WebService), so I only need to replace the server address.
2. Show how to extract the desired data from the query string to restore the data to the webpage, similar to the viewstate function of Asp.net.

③ Netstat-nao
The webservice connection port is also normal and is not occupied by other ports.
④ Telenet ip address and port
If the connection fails, this is definitely a problem. How can this problem be solved? I asked a professional about how to modify the server jump point.
⑤ Jump point
I am not quite clear about the jump point. I will first ask du Niang:
