2.5.6配置 jbpm.cfg.xml
使用自己的SessionImpl，在文件后面加上
<transaction-context>
<hibernate-session current="true"/>
<object />
-->
在jbpm.hibernate.cfg.xml 注入自己的
<mapping resource="customize.hbm.xml" />
2.5.7自定义hibernate映射文件
新建 customize.hbm.xml,内容如下
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="org.jbpm.pvm.internal.identity.impl" default-access="field">
<!-- ### USER ########################################################### -->
<class name="com.t.MesUser" table="JBPM4_CUSTOMIZE_USER">
<id name="dbid" column="DBID_">
<generator />
</id>
<version name="dbversion" column="DBVERSION_" />
<property name="id" column="USERID_" /> <!-- 登陆ID -->
<property name="userNo" column="USERNO_" /> <!-- 员工工号 -->
<property name="userName" column="USERNAME_" /> <!-- 姓名 -->

<property name="remarks" column="REMARKS_" />
<many-to-one name="parentGroup"
column="PARENT_"?

</class>
</hibernate-mapping>
集成自己的表就完成了。当你调用 identityService.createUser()方法时，就往你自定义的user表里插入了一条记录。
2.6新建用户和组
identityService.createGroup("user_dept"); // 部门
identityService.createUser("user1", "test1", "test1"); // 新建用户1
identityService.createUser("user2", "test2", "test2"); /./新建用户2
identityService.createMembership("user1", "user_dept"); // 绑定用户和部门的关系
identityService.createMembership("user2", "user_dept");
2.7发布流程
发布流程：
ProcessEngine processEngine = Configuration.getProcessEngine();
RepositoryService repositoryService = processEngine
.getRepositoryService();
String deployId = repositoryService.createDeployment().addResourceFromClasspath("com/contract/contract.jpdl.xml").deploy();
删除流程:repositoryService.deleteDeploymentCascade(deployId));
2.8开始流程实例
executionService.startProcessInstanceById(request.getParameter("id"));
