before entering this question, let's look at Drools: in many industry applications such as banking, insurance, business rules are often very complex and rules are constantly evolving, and many of the existing system practices are essentially binding business rules to program code. the main problems are as follows: 1) When the business rules change, the corresponding code will have to change, every time even small changes need to go through the develo

1, the basic matching rules 1.1 Variables Drools uses the matching method to compare the fact, such as Java code account:account (Balance > 100) The meaning of this rule is to find all account instances with the type account in fact and the balance property value greater than 100. You can specify a variable to describe a type or a property that maps a class. For example, Java code $account: Account ($type:

1. What is drools. Drools is a Java-language based rule engine framework. Solves the problem that the complex business logic in the business system is hard coded into the program code. The advent of drools can separate business logic from program code, and can also change business logic in real time. Support the rule implementation of simple scripting language,
