整合規則引擎urule

最近在做urle的規則引擎的整合，記錄一下遇到的坑

客戶端：

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 {
        //創建一個KnowledgeSession對象
        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 -> 每次都從服務端拉取
#1 -> 緩存在本地

    knowledgeUpdateCycle: 1

pom:

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

注：客戶端一般沒什么問題，但是我在配置的時候遇到jar包沖突的問題，是日志的jar包沖突，解決一下就好了

服務端：

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://測試
        databasetype: mysql
        datasourcename: datasource

這里要注意：spring的datasource屬性的url要改成jdbc-url，不然會報錯，感覺是因為datasource屬性被引用后項目把他當作一個數據源了。

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>

導入dbcp的jar包是因為配置類中需要dbcp的配置，導入io包的原因是在項目啟動后，添加變量庫保存文件時會報一個NoClassDefFoundError的錯誤，視情況而定
