Dear All

最近在做Drools6.3集成Spring Web应用,简直是噩梦啊。

1. 创建了maven web工程,将各种依赖包导入;

2. 在main/resources下创建,drools-bean.xml,并导入到applicationContext.xml中,drools-bean.xml文件内容如下:


<?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:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:task="http://www.springframework.org/schema/task" xmlns:kie="http://drools.org/schema/kie-spring" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd http://drools.org/schema/kie-spring https://raw.githubusercontent.com/droolsjbpm/droolsjbpm-integration/master/kie-spring/src/main/resources/org/kie/spring/kie-spring-6.0.0.xsd" default-lazy-init="true"> <kie:kmodule id="test-kmodule"> <kie:kbase name="test_kbase" packages="rules.test"> <kie:ksession name="ksession1" scope="prototype"/> </kie:kbase> </kie:kmodule> <bean id="kiePostProcessor" class="org.kie.spring.KModuleBeanFactoryPostProcessor" /> </beans>


tomcat一启动就报错,错误如下:

我的疑问:按照Drools6.3的官方文档,在Spring中定义<kmodule>是可以替换掉kmodule.xml文件的,感觉这个初始化是去zip文件,或者说是jar文件中找drl规则去了,我放到classes根目录下的规则文件视而不见,请问我是啥配置不对么?

找到原因了,我的Eclipse工程将web应用发布到了C盘:C:\Users\duanjunwei\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps,但Tomcat是在D盘,可能Drools不认C盘,修改下Eclipse下的tomcat发布路径配置Server Locations,选择第二项:Tomcat Installation,然后重新发布就可以了。这个问题折腾了好几天,Drools坑还是很多的。
