整合规则引擎urule

最近在做urle的规则引擎的整合，记录一下遇到的坑

客户端：

RuleConfig:

@Configuration
@ImportResource({"classpath:urule-core-context.xml"})
public class RuleConfig {
    @Bean
    public PropertySourcesPlaceholderConfigurer propertySourceLoader() {
        PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
        configurer.setIgnoreUnresolvablePlaceholders(true);
        configurer.setOrder(1);
        return configurer;
    }
}

RuleController:

@RestController
public class RuleController {
    @RequestMapping("rule")
    public String rule(@RequestParam String data) throws IOException {
        //创建一个KnowledgeSession对象
        KnowledgeService knowledgeService = (KnowledgeService) Utils.getApplicationContext().getBean(KnowledgeService.BEAN_ID);
        KnowledgePackage knowledgePackage = knowledgeService.getKnowledge("aaa/bag");
        KnowledgeSession session = KnowledgeSessionFactory.newKnowledgeSession(knowledgePackage);

        Integer integer = Integer.valueOf(data);
        Map<String, Object> param = new HashMap();
        param.put("var", integer);
        session.fireRules(param);

        Integer result = (Integer) session.getParameter("var");
        return String.valueOf(result);
    }
}

yml:

urule:
    resporityServerUrl: http://localhost:9502

#0 -> 每次都从服务端拉取
#1 -> 缓存在本地

    knowledgeUpdateCycle: 1

pom:

<dependency>
    <groupId>com.bstek.urule</groupId>
    <artifactId>urule-console</artifactId>
    <version>2.1.7</version>
</dependency>

注：客户端一般没什么问题，但是我在配置的时候遇到jar包冲突的问题，是日志的jar包冲突，解决一下就好了

服务端：

dataSourceConfig:

@Configuration
@ImportResource({"classpath:urule-console-context.xml"})
@PropertySource(value = {"classpath:urule-console-context.properties"})
public class dataSourceConfig {
    @Bean
    public PropertySourcesPlaceholderConfigurer propertySourceLoader() {
        PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
        configurer.setIgnoreUnresolvablePlaceholders(true);
        configurer.setOrder(1);
        return configurer;
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource datasource() {
        return DataSourceBuilder.create().build();
    }

}

URuleServletRegistration:

@Component
public class URuleServletRegistration {
    @Bean
    public ServletRegistrationBean<HttpServlet> registerURuleServlet() {
        return new ServletRegistrationBean<>(new URuleServlet(), "/urule/*");
    }
}

yml:

urule:
    repository:
        #        dir: d://测试
        databasetype: mysql
        datasourcename: datasource

这里要注意：spring的datasource属性的url要改成jdbc-url，不然会报错，感觉是因为datasource属性被引用后项目把他当作一个数据源了。

pom：

<dependency>
    <groupId>com.bstek.urule</groupId>
    <artifactId>urule-console</artifactId>
    <version>2.1.7</version>
    <exclusions>
        <exclusion>
            <artifactId>slf4j-jdk14</artifactId>
            <groupId>org.slf4j</groupId>
        </exclusion>
    </exclusions>
</dependency>

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.8.0</version>
</dependency>

<dependency>
    <groupId>commons-dbcp</groupId>
    <artifactId>commons-dbcp</artifactId>
    <version>1.4</version>
</dependency>

导入dbcp的jar包是因为配置类中需要dbcp的配置，导入io包的原因是在项目启动后，添加变量库保存文件时会报一个NoClassDefFoundError的错误，视情况而定
