Drools与Spring集成登录测试

来源：互联网发布：8月外贸数据编辑：程序博客网时间：2024/05/21 11:22

Drools5.2.0.Final与Spring3集成测试

在drools5.2，有一个jar包：drools-spring-5.2.0.Final.jar，其中定义了在spring中应用的drools的扩展。通过这些扩展，可以直接在spring的配置文件中，配置knowledgebase、session等bean，从而在spring配置的程序中直接应用。

drools-spring-5.2.0.Final.jar在droolsjbpm-integration-distribution-5.2.0.Final\binaries文件夹下。
