我是Kie Workbench的新手。我正在使用Java Rest调用在kie工作台中触发规则。请在下面找到代码:
public class RuleEngineConnector {
@Value("${brms.execution.server.url}")
private String SERVER_URL;
@Value("${brms.execution.server.username}")
private String USER;
@Value("${brms.execution.server.password}")
private String PASSWORD;
@Value("${brms.containerId}")
private String CONTAINER_ID;
private static final MarshallingFormat FORMAT = MarshallingFormat.JAXB;
public String getAdapter(AdapterRuleDO adapterRule) {
KieServicesConfiguration cfg = KieServicesFactory.newRestConfiguration(SERVER_URL, USER, PASSWORD);
cfg.setMarshallingFormat(FORMAT);
Set<Class<?>> extraClasses = new HashSet<Class<?>>();
extraClasses.add(AdapterRuleDO.class);
cfg.addJaxbClasses(extraClasses);
KieServicesClient kieServicesClient = KieServicesFactory.newKieServicesClient(cfg);
ServiceResponse<ExecutionResults> response = getRulesResponse(adapterRule, kieServicesClient);
List<AdapterRuleDO> listOfObjects = (List<AdapterRuleDO>) response.getResult().getValue("get-adapter");//to be changed
return listOfObjects.get(0).getAdapterName();
}
private ServiceResponse<ExecutionResults> getRulesResponse(AdapterRuleDO adapterRule, KieServicesClient kieServicesClient) {
List<Command<?>> commands = new ArrayList<Command<?>>();
KieCommands commandsFactory = KieServices.Factory.get().getCommands();
commands.add(commandsFactory.newInsert(adapterRule, "adapterRule"));
commands.add(commandsFactory.newFireAllRules());
commands.add(commandsFactory.newGetObjects("get-adapter"));
BatchExecutionCommand batchExecution = commandsFactory.newBatchExecution(commands);
RuleServicesClient ruleServicesClient = kieServicesClient.getServicesClient(RuleServicesClient.class);
ServiceResponse<ExecutionResults> response = ruleServicesClient.executeCommandsWithResults(CONTAINER_ID, batchExecution);
return response;
}
}
我正在正确触发规则,并且在触发规则后在AdapterRuleDO类中正确更新了值。一个问题是,当我再次调用此方法第二次执行规则时,我收到两个AdapterRuleDO对象,而对于每次后续调用,我都会得到一个附加对象。似乎会话中的对象已存储,并且没有为每个调用清除。我如何才能实现每个调用只能返回一个AdapterRuleDO对象的目的?
请注意,我只有一个使用了这一事实的决策表。
最佳答案
在搜索了不同的博客和用户论坛后,得到了一个很好的解决方案。上述问题可以通过以下步骤解决:
1)使用“ adapterRule”而不是“ get-adapter”来获取结果。
2)在KIE Workbench中,搜索部署描述符并进行以下更改:
<runtime-strategy>PER_REQUEST</runtime-strategy>
默认情况下,运行时策略为SINGLETON。
希望这有道理并能帮助别人。
