Question

我通过Java（又名JRules）使用IBM的ILOG 7.1。我需要调试一些预先存在的功能，其中有一组规则正在执行。只有一些应该执行的规则实际上在我的跟踪输出中。所以我想知道：

规则是否实际上没有执行？
规则是否只是作为跟踪的一部分输出？

我不确定。

我必须执行并记录跟踪规则的Java代码如下：

public RulesDTO executeRules(RulesDTO rulesDTO) {
    try {
        String sessionId = rulesDTO.getSessionId();
        String clientIp = rulesDTO.getClientIp();
        LOG.info("Starting to execute rules.");
        String ruleSetName = rulesDTO.getRuleSetName();
        IlrSessionRequest request = this.rulesSessionProvider
                .createRequest(ruleSetName);

        Map<String, Object> parNameToObjectMap = new HashMap<String, Object>();
        parNameToObjectMap.put("params", rulesDTO);
        parNameToObjectMap.put("timeOut",
                getEngineExecutionTimeout());
        request.setInputParameters(parNameToObjectMap);
        boolean isTraceEnabled = true;

        // Enable trace to retrieve info on executed rules
        request.setTraceEnabled(isTraceEnabled);
        // get all traces
        request.getTraceFilter().setInfoAllFilters(isTraceEnabled);

        IlrSessionResponse response = null;
        try {
            // calls ILOG engine, itself, to execute rules
            response = executeRulesRequest(request, ruleSetName);
        }
        catch (TimeoutException te) {
            LOG.error(String.format("Rules %s timed out [timeout=%d]",
                    ruleSetName, getEngineExecutionTimeout()));
            throw te;
        }

        logRuleExecutions(rulesDTO.getID(), sessionId, response);

        return rulesDTO;
    }
    catch (Throwable t) {
        LOG.error("Rule set execution failed. ilogVersion=7.1", t);
        throw new RulesException(
                "Rule set execution failed. ilogVersion=7.1", t);
    }
}

private void logRuleExecutions(
        long searchId, String sessionId, IlrSessionResponse response) {
    IlrExecutionTrace executionTrace = response.getRulesetExecutionTrace();
    List<IlrExecutionEvent> executionEvents = executionTrace.getExecutionEvents();
    // ExecutedRule is a custom class I have wrapping IlrExecutionEvent
    List<ExecutedRule> executedRules = getRuleExecutions(executionEvents);
    int numRulesExecuted = executedRules.size();
    LOG.info("sessionId={}, SearchId={}, numRules={}",
            new Object[] {sessionId, searchId, numRulesExecuted});

    // loop over executedRules list and just log each one
    logFilteredRules(executedRules, searchId, sessionId);
}

private List<ExecutedRule> getRuleExecutions(List<IlrExecutionEvent> executionEvents) {
    List<ExecutedRule> executedRules = new LinkedList<ExecutedRule>();
    for (IlrExecutionEvent event : executionEvents) {
        if (event instanceof IlrRuleEvent) {
            IlrRuleEvent ruleEvent = (IlrRuleEvent) event;
            allRuleExecutions.add(convertToRuleExecution(ruleEvent));
        }
        else {
            List<IlrExecutionEvent> subEvents = ((IlrTaskEvent) event).getSubExecutionEvents();
            LOG.debug("Size of subEvents={}", subEvents.size());
            List<ExecutedRule> executedSubRules = getRuleExecutions(subEvents);
            executedRules.addAll(executedSubRules);
        }
    }
}

除了事实上只有一些规则似乎被调用之外，似乎只调用了早期的规则，而不是在初始规则之后应该执行的规则。任何帮助将不胜感激。谢谢。： - ）

我的ILOG规则被调用了，还是我的ILOG跟踪问题？
