要在Spring Boot中测试Drools规则,你需要遵循以下步骤:
- 添加依赖项 确保你的项目中包含了以下依赖项:
<groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency><dependency> <groupId>org.drools</groupId> <artifactId>drools-compiler</artifactId> <version>7.59.0.Final</version> </dependency><dependency> <groupId>org.drools</groupId> <artifactId>drools-decisiontables</artifactId> <version>7.59.0.Final</version> </dependency><dependency> <groupId>org.kie</groupId> <artifactId>kie-spring</artifactId> <version>7.59.0.Final</version> </dependency>
- 创建Drools规则文件 在
src/main/resources
目录下创建一个名为rules
的文件夹。在此文件夹中,创建一个名为sampleRule.drl
的文件,并添加以下内容:
package com.example.drools rule "Sample Rule" when $person: Person(age < 18) then System.out.println("Person is under 18 years old."); end
- 创建实体类 在
com.example.drools
包中创建一个名为Person
的Java类,并添加以下内容:
public class Person { private String name; private int age; // Getters and setters }
- 配置Drools 在
com.example.drools
包中创建一个名为DroolsConfig
的Java类,并添加以下内容:
import org.kie.api.KieBase; import org.kie.api.KieServices; import org.kie.api.builder.KieBuilder; import org.kie.api.builder.KieFileSystem; import org.kie.api.builder.KieRepository; import org.kie.api.runtime.KieContainer; import org.kie.api.runtime.KieSession; import org.kie.internal.io.ResourceFactory; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class DroolsConfig { @Bean public KieBase kieBase() { KieServices kieServices = KieServices.Factory.get(); KieRepository kieRepository = kieServices.getRepository(); KieFileSystem kieFileSystem = kieServices.newKieFileSystem(); kieFileSystem.write(ResourceFactory.newClassPathResource("rules/sampleRule.drl")); KieBuilder kieBuilder = kieServices.newKieBuilder(kieFileSystem); kieBuilder.buildAll(); KieContainer kieContainer = kieServices.newKieContainer(kieRepository.getDefaultReleaseId()); return kieContainer.getKieBase(); } @Bean public KieSession kieSession() { return kieBase().newKieSession(); } }
- 编写测试用例 在
com.example.drools
包中创建一个名为DroolsTest
的Java类,并添加以下内容:
import org.junit.jupiter.api.Test; import org.kie.api.runtime.KieSession; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import static org.junit.jupiter.api.Assertions.*; @SpringBootTest class DroolsTest { @Autowired private KieSession kieSession; @Test void testSampleRule() { Person person = new Person(); person.setName("John Doe"); person.setAge(16); kieSession.insert(person); int rulesFired = kieSession.fireAllRules(); assertEquals(1, rulesFired); } }
现在,你可以运行DroolsTest
类中的测试用例来测试Drools规则。如果规则被正确触发,测试将通过。
