Little brother here to talk about his drools in combat in the end how to use the view: First, if the rules are written by developers, such as programming DRL files, in this case, you can play the rules into a jar package, deployed to Workbench, or kie-server; Second, if the rules are configurable, so that the business staff to configure, do not require the participation of developers, you can save the rules in the form of a string to the database;
