本文详细介绍使用Activiti流程引擎进行流程定义的查询、启动、任务处理及删除等操作，包括流程部署信息、流程定义数据的查询，流程图查看，个人任务查询与完成，以及流程定义的删除。

查询流程部署信息表
表 act_re_deployment

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.repository.Deployment;

public class Text6 {
    //act_re_deployment 	部署信息表
    public static void main(String[] args) {
        //查询部署的流程定义
        ProcessEngine pe=
                ProcessEngines.getDefaultProcessEngine();
        //查询部署对象的信息
        Deployment d=pe.getRepositoryService()
                .createDeploymentQuery()
                .list().get(0);
        System.out.println(d.getId()+","+d.getName()+","+d.getDeploymentTime());


    }
}

查询流程定义数据表

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.ProcessDefinition;

public class Text61 {
    //act_re_procdef      流程定义数据表
    public static void main(String[] args) {
        //查询部署的流程定义
        ProcessEngine pe=
                ProcessEngines.getDefaultProcessEngine();

        //查询流程定义的信息
        ProcessDefinition definition=
                pe.getRepositoryService()
                .createProcessDefinitionQuery()
                //.deploymentId("1") //根基id查找
                //.processDefinitionKey("myProcess_1")//通过流程定义的key值进行查询,只能得到一个值,是数据库最先查到key
                .processDefinitionKeyLike("%1%")//通过流程定义的key模糊查询
                .orderByProcessDefinitionVersion().asc()
                //.orderByProcessDefinitionVersion().desc()
                .list().get(0);
        System.out.println("流程定义的id:"+definition.getId());
        System.out.println("流程定义的key"+definition.getKey());
        System.out.println("流程定义的name"+definition.getName());
        System.out.println("流程定义的资源文件:"+definition.getResourceName());
        System.out.println("流程定义的图片文件:"+definition.getDiagramResourceName());
        System.out.println("流程定义的版本:"+definition.getVersion());

    }
}

删除流程定义
act_re_deployment 部署信息表

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;

public class Text63 {
    //删除流程定义
    public static void main(String[] args) {
        ProcessEngine pe= ProcessEngines.getDefaultProcessEngine();
        //act_re_deployment 	部署信息表
        pe.getRepositoryService().deleteDeployment("1");
        System.out.println("删除");
    }
}

查询key值相同的多版本流程定义

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.repository.ProcessDefinition;

import java.util.List;

public class Text64 {
    //查询同key的多版本流程定义
    public static void main(String[] args) {
        ProcessEngine pe=ProcessEngines.getDefaultProcessEngine();
        List<ProcessDefinition> list=pe.getRepositoryService()
                .createProcessDefinitionQuery()
                .processDefinitionKey("myProcess_1")
                .list();
        for(ProcessDefinition definition:list){
            System.out.println("流程定义的id："+definition.getId());
            System.out.println("流程定义的key:"+definition.getKey());
            System.out.println("流程定义的name："+definition.getName());
            System.out.println("流程定义的资源文件:"+definition.getResourceName());
            System.out.println("流程定义图片文件:"+definition.getDiagramResourceName());
            System.out.println("流程定义的版本:"+definition.getVersion());

        }
    }
}
