一、事件日志

配置Event Logging
- 实验性的事件记录机制，性能影响较大
- 开启默认记录所有数据的变化过程，表记录快速增长
- 日志内容json格式，建议存入mongoDB、Elastic Search

具体实现代码

java

package com.laogoubi.config;

import org.activiti.engine.event.EventLogEntry;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.activiti.engine.test.ActivitiRule;
import org.activiti.engine.test.Deployment;
import org.junit.Rule;
import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.util.List;

/**
 * @ClassName ConfigEventLogTest
 * @Description EventLog
 * @Author eastern
 * @Date 2020/6/27 下午10:55
 * @Version 1.0
 **/
public class ConfigEventLogTest {

	private static final Logger logger = LoggerFactory.getLogger(ConfigEventLogTest.class);

	@Rule
	public ActivitiRule activitiRule = new ActivitiRule("activiti_eventlog.cfg.xml");

	@Test
	@Deployment(resources = {"com/laogoubi/my-process.bpmn20.xml"})
	public void test() {
		ProcessInstance processInstance = activitiRule.getRuntimeService().startProcessInstanceByKey("my-process");
		Task task = activitiRule.getTaskService().createTaskQuery().singleResult();
		activitiRule.getTaskService().complete(task.getId());
		List<EventLogEntry> eventLogEntryList =
				activitiRule.getManagementService().getEventLogEntriesByProcessInstanceId(processInstance.getProcessInstanceId());
		for (EventLogEntry eventLogEntry : eventLogEntryList) {
			logger.info("eventLogEntry.type = {}, eventLogEntry.data = {}", eventLogEntry.getType(), new String(eventLogEntry.getData()));
		}
		logger.info("eventLogEntryList.size = {}", eventLogEntryList.size());

	}
}

配置文件：activiti_eventlog.cfg.xml

xml
