jPBM4.3 -- 第二节 管理流程定义

1.添加依赖的jar包

把jbpm.jar和lib文件夹下的所有jar包加到项目中

2.添加配置文件

把jbpm-4.3\examples\src路径下的

jbpm.cfg.xml

jbpm.hibernate.cfg.xml

jbpm.mail.properties

jbpm.mail.templates.examples.xml

logging.properties

拷贝到src目录下如图所示：

 

写一个test类进行测试代码如下

package com.darren;

 

import java.util.List;

import org.jbpm.api.Configuration;

import org.jbpm.api.NewDeployment;

import org.jbpm.api.ProcessDefinition;

import org.jbpm.api.ProcessDefinitionQuery;

import org.jbpm.api.ProcessEngine;

import org.jbpm.api.RepositoryService;

import org.junit.Test;

 

publicclass HelloWordTest {

 

    @Test

    publicvoid testDeploy() {

 

        // 1.get the singleton ProcessEngine that is created from the default

        // configuration file 'jbpm.cfg.xml'

        // 1.使用默认的配置文件创建流程引擎 -》自动寻找classpath下的jbpm.cfg.xml文件

        ProcessEngine processEngine = Configuration.getProcessEngine();

 

        // 2.the repository service that provides access to the process

        // repository.

        // 2.得到了访问流程存储库的服务

        RepositoryService repositoryService = processEngine.getRepositoryService();

 

        // 3.create a new deployment. The deployment will only be deployed into

        // the repository after invoking the NewDeployment.deploy().

        // 3.创建一个新的部署。部署只会被部署到存储库调用NewDeployment.deploy后()。

        NewDeployment newDeployment = repositoryService.createDeployment();

 

        // 4.adds a resource as a resource from theclasspath

        // 4.从classpath路径添加一个资源

        newDeployment.addResourceFromClasspath("helloWorld.jpdl.xml");

 

        // 5.after adding resources, this will perform the actual deployment.

        // 5.在添加资源后,这将执行实际的部署，部署流程，并返回流程的Id

        String deploymentId = newDeployment.deploy();

 

        // create a query for process definitions

        //创建一个查询过程定义

        ProcessDefinitionQuery processDefinitionQuery = repositoryService.createProcessDefinitionQuery();

 

        // execute the query and obtain the list of ProcessDefinitions

        //执行查询和获得ProcessDefinitions的列表

        List<ProcessDefinition> processDefiniList = processDefinitionQuery.list();

 

        for (ProcessDefinition definition : processDefiniList) {

            System.out.println(definition.getId());

        }

 

        // deletes deployment, contained process definitions, related process

        // instances and their history information

        //删除部署,包含流程定义,相关的过程实例和他们的历史信息

        repositoryService.deleteDeploymentCascade(deploymentId);

        System.out.println(repositoryService.createProcessDefinitionQuery().list().size());

    }

}
