No rules are fired in helloworld using Spring rest controller!
Wei Xiong
I am using Drools 6.5.0 with Spring boot. I have a very weird problem. I can successfully execute the helloworld rule in test environment but not through Spring rest controller. Both are using the same function from a service. Could you please help?
I have the following rules from Drools examples:
=========================================================
rule "Hello World"
dialect "mvel"
when
m : Message( status == Message.HELLO, message : message )
then
System.out.println( message );
// modify ( m ) { setMessage( "Goodbyte cruel world" ),
// setStatus( Message.GOODBYE ) };
modify ( m ) { message = "Goodbye cruel world",
status = Message.GOODBYE };
end
rule "Good Bye"
dialect "java"
when
Message( status == Message.GOODBYE, message : message )
then
System.out.println( message );
end
And I have the following as a service
@Service
@Transactional
public class RuleService {
private final Logger log = LoggerFactory.getLogger(RuleService.class);
@Autowired
private KieContainer kieContainer;
RuleService() {
}
public String ruleTest() {
log.debug("in ruleTest()");
KieSession ksession = this.kieContainer.newKieSession("PriceRulesKS");
ksession.setGlobal("list", new ArrayList<Object>());
final Message message = new Message();
message.setMessage("Hello World");
message.setStatus(Message.HELLO);
ksession.insert(message);
// and fire the rules
int ruleFiredCount = ksession.fireAllRules();
System.out.println("Rules checked: " + ruleFiredCount);
log.debug("Rules checked: " + ruleFiredCount);
ksession.dispose();
return message.getMessage();
}
}
=========================================================
And I have the following config
=========================================================
@Configuration
public class RuleConfiguration {
@Bean
public KieContainer kieContainer() throws IOException {
KieServices ks = KieServices.Factory.get();
return ks.getKieClasspathContainer();
}
}
=========================================================
For the following test environment, I was able to have 2 rules fired.
==========================================================
@RunWith(SpringRunner.class)
@SpringBootTest(classes = SmartPriceApp.class)
@Transactional
public class RuleServiceIntTest {
@Autowired
private RuleService ruleService;
@Test
public void testRuleService() {
String msg = ruleService.ruleTest(); //Two rules are fired!
System.out.println(msg);
}
}
==========================================================
However, if I am using the spring rest controller, No rules were fired. I need your help.
==========================================================
@RestController
@RequestMapping("/api")
public class PriceResource {
private final RuleService ruleService;
public PriceResource(RuleService ruleService) {
this.ruleService = ruleService;
}
@PostMapping(path="/priceres")
public PriceResult priceres(@RequestBody RequestWrapper requestWrapper) {
System.out.println(requestWrapper.product);
System.out.println(requestWrapper.customer);
String msg = this.ruleService.ruleTest(); //No rules are fired!
return new PriceResult(234.7, msg);
}
}
==========================================================
