You should first read the manual, then try google it. There have also been questions like this asked before, for example: How to deploy Drools Flow and rules by my web application

你应该先阅读手册,然后尝试谷歌它。之前也有人问过这样的问题,例如:How to deploy Drools Flow and rules by my web application

But anyways. This is how to integrate it if you use Maven and Spring:

但无论如何。如果您使用 Maven 和 Spring,这是如何集成它的:

you first need to include Drools dependencies:

您首先需要包含 Drools 依赖项:

    <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:

定义应用上下文:

<?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 inject ksession1as a bean.

然后你可以注入ksession1一个bean。

Try google: First result for Drools Maven Tutorial: http://www.installationwiki.org/Set_Up_for_JBoss_Drools.

试试谷歌:第一个结果Drools Maven Tutorialhttp: //www.installationwiki.org/Set_Up_for_JBoss_Drools

Note that Maven is a "build" tool (actually it's more) whereas Drools is a platform/library. So using Drools does normally not depend on Maven. You might thus want to get separate tutorials.

请注意,Maven 是一个“构建”工具(实际上它更多),而 Drools 是一个平台/库。所以使用 Drools 通常不依赖于 Maven。因此,您可能希望获得单独的教程。
