Recently, I participated in the ERP system development of a material company, mainly responsible for warehousing systems. As the company's business processes are relatively complex and changeable, it is so painful to do it that It is immersed in the endless loop of business code change. Over time, there is a sense of despair. How can we adapt to such complex business changes well or easily? Recently, I did not really look at the posts of the great gods in the garden, but I have little but I may

For specific examples, see drools5.1 rule stream example. I have been developing applications based on rules and rules engines for a while. Now I will write some experiences for your reference. 1.The separation of logical expression and execution. This is fundamental.The implementation of business logic can be subdivided into the expression and execution of business logic. In traditional code, expressions and executions are mixed and expressed and ex
