卡蒙达不包含任何历史记录

我有一个问题,每当我在Camunda process Service中创建一个流程实例时,它都不会写入任何ACT_HI_OP_LOG。我不知道为什么它不将历史保存到数据库中。

@Component
@Order(Ordering.DEFAULT_ORDER + 1)
public class ProcessEngineConfiguration implements ProcessEnginePlugin {

    private String tenantId;

    @Override
    public void preInit(ProcessEngineConfigurationImpl processEngineConfiguration) {
        HistoryLevel historyLevel = new HistoryLevelFull();
        processEngineConfiguration.setHistoryLevel(historyLevel);
        processEngineConfiguration.setTenantCheckEnabled(true);
//      processEngineConfiguration.setHistory(org.camunda.bpm.engine.ProcessEngineConfiguration.HISTORY_FULL);
        processEngineConfiguration.setTenantIdProvider(new TenantIdProvider() {

            @Override
            public String provideTenantIdForProcessInstance(TenantIdProviderProcessInstanceContext ctx) {
                return tenantId;
            }

            @Override
            public String provideTenantIdForHistoricDecisionInstance(TenantIdProviderHistoricDecisionInstanceContext ctx) {
                return tenantId;
            }

            @Override
            public String provideTenantIdForCaseInstance(TenantIdProviderCaseInstanceContext ctx) {
                return tenantId;
            }
        });

        processEngineConfiguration.setJobExecutor(processEngineConfiguration.getJobExecutor());

    }

我就是这样开始这个过程的。

ProcessInstance pi = null;

        try {
            identityService.setAuthentication(getAuthentication());
            pi = runtimeService.startProcessInstanceByKey(flowName, businessKey, variables);


        } finally {
            identityService.setAuthentication(null);
        }
        if (pi == null)
            return null;
