In this case, the project is created, and the development environment is ready below. 2. Prepare the Activiti Development Environment 2.1: add the Activiti jar package

Under the activiti-5.21.0-> directory are some sample projects that extract the activiti-rest project and import all the packages under the WEB-INF/lib in the activiti-rest directory. Add to classpath.

Because we are using the Mysql database, the Link driver of the Mysql database is not provided in the Activiti official package. We need to import it ourselves. Import the mysql-connector-java-5.1.7-bin.jar manually and add it to classpath.
