The STS and Virgo environments have been configured above, and the Virgo server can be successfully run. Next we will use STS to build several projects.
We simulate an example of registration. In our actual case, data is sometimes written to the database, written to a file, or written to the memory, which is convenient for different operations. This example may not completely explain the problem, but it is enough to explain how to build a project th
