Example Analysis of mybatis reverse Engineering

This article shares with you the content of a sample analysis of mybatis reverse engineering. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

In the past, during the live broadcast, some friends saw that the editor used the tool to generate mybatis entity classes, mapper files and dao,service,controller.

two. Springboot multi-environment configuration

Sometimes, we do not want to configure the database, but sometimes we do use the database, so it is very inconvenient to delete, add and delete each time. Therefore, there is a multi-environment configuration, which is easier. Just rename the file, as shown in the following figure:

This module only encapsulates some common functions of jdk, such as this initialization writes a common tool method: convert the first letter of String to uppercase, followed by lowercase.
