How to deploy Drools stream and rules using my web application

Question

I just started my new project. My project manager said that Drools is a new technology and we will include the flow and drools rules and integrate our web application with it.

How to integrate Drools streams and rules into a web application?

Answer 1

It depends on what technology you use. If, for example, you use Java + Maven + Spring, you first need to enable the Drools dependencies:

<dependency> <groupId>org.drools</groupId> <artifactId>drools-core</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>drools-compiler</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>drools-spring</artifactId> <version>${drools.version}</version> </dependency> 

Define the application context:

 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:drools="http://drools.org/schema/drools-spring" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://drools.org/schema/drools-spring http://drools.org/schema/drools-spring.xsd"> <drools:kbase id="kbase1"> <drools:resources> <drools:resource source="classpath:Sample.drl" /> </drools:resources> </drools:kbase> <drools:ksession id="ksession1" type="stateful" kbase="kbase1" /> </beans> 

Then you can enter ksession1 as a bean.
