2.5集成自定义用户表
2.5.1 Jbpm4提供了实现接口

1.interface User
2.Interface Group
3.Interface  GroupMember
4.Interface   IdentitySession
想要集成自己的表，首先需要实现jbpm提供的接口，然后再进行配置。
2.5.2 User 用户表
import java.io.Serializable;
import java.sql.Blob;
import org.jbpm.api.identity.User;
/**
* 用户表 MesUser
*
* @version 1.0
*
*/
public class MesUser implements Serializable, User {
private static final long serialVersionUID = 1L;
private String id;
private String userNo;// 员工工号
private String userName;// 员工姓名
private String userSex;// 性别

private String userPassword;// 密码
private String userType;// 类型
private String userMail;// 电子邮件

private String isValid;// 是否有效Y/N
private Blob signaturePic;// 电子签名
private String remarks;// 备注
protected long dbid; // 数据库内部自生成的ID
protected int dbversion;

public int getDbversion() {

return dbversion;

}

public MesUser() {

}

public MesUser(String id, String userName, String userMail) {

this.id = id;

this.userName = userName;

this.userMail = userMail;

}

public void setDbversion(int dbversion) {
this.dbversion = dbversion;
}

public long getDbid() {
return dbid;
}

public void setDbid(long dbid) {
this.dbid = dbid;
}

public void setId(String id) {

this.id = id;

}

public String getUserNo() {

return userNo;

}

public void setUserNo(String userNo) {

this.userNo = userNo;

}

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

public String getUserSex() {

return userSex;

}

public void setUserSex(String userSex) {

this.userSex = userSex;

}

public String getUserPassword() {

}

public void setUserPassword(String userPassword) {

}

public String getUserType() {

}

public void setUserMail(String userMail) {

}

public String getIsValid() {

return isValid;

}

public void setIsValid(String isValid) {

this.isValid = isValid;

}

public Blob getSignaturePic() {

return signaturePic;

}

public void setSignaturePic(Blob signaturePic) {

this.signaturePic = signaturePic;

}

public String getRemarks() {

return remarks;

}

public void setRemarks(String remarks) {

this.remarks = remarks;

}

/**

* 显示用户姓名+工号

*

* @return

*/

public String getDisplayName() {

return userName + "(" + id + ")";

}

// 实现User接口所必须实现的几个方法

public String getId() {

return this.id;

}

public String getGivenName() {

return null;

}

public String getFamilyName() {

return null;

}

public String getBusinessEmail() {

return this.userMail;

}

}
2.5.3 Group部门表

import java.io.Serializable;

import org.jbpm.api.identity.Group;

public class MesGroup implements Serializable,Group {

private static final long serialVersionUID = 1L;

private String id;

private String groupName;//组织名称

private String groupType;//组织类型

private MesGroup parentGroup;//父组织

private String remarks;//备注

protected long dbid;

protected int dbversion;

public int getDbversion() {

return dbversion;

}

public void setDbversion(int dbversion) {

this.dbversion = dbversion;

}

public long getDbid() {

return dbid;

}

public void setDbid(long dbid) {

this.dbid = dbid;

}

public String getParentGroupID() {

return parentGroup!=null?parentGroup.getId():null;

}

public String getParentGroupName() {

return parentGroup==null ? "xxx" : parentGroup.getGroupName();

}

public void setId(String id) {

this.id = id;

}

public String getGroupName() {

return groupName;

}

public void setGroupName(String groupName) {

this.groupName = groupName;

}

public String getGroupType() {

return groupType;

}

public void setGroupType(String groupType) {

this.groupType = groupType;

}

public MesGroup getParentGroup() {

return parentGroup;

}

public void setParentGroup(MesGroup parentGroup) {

this.parentGroup = parentGroup;

}

public String getRemarks() {

return remarks;

}

public void setRemarks(String remarks) {

this.remarks = remarks;

}

//实现Group接口必须的几个方法

public String getName(){

return this.groupName;

} 

public String getType(){

return this.groupType;

}

public String getId() {

return id;

}

}
2.5.4 GroupMember 用户部门关系表

import java.io.Serializable;

public class MesGroupMember implements Serializable {

private static final long serialVersionUID = 1L;

protected long dbid;

protected int dbversion;

private MesUser user;

private MesGroup group;

protected String role;

public int getDbversion() {

return dbversion;

}

public void setDbversion(int dbversion) {

this.dbversion = dbversion;

}

public long getDbid() {

return dbid;

}

public String getRole() {

return role;

}

public void setRole(String role) {

this.role = role;

}

public void setDbid(long dbid) {

this.dbid = dbid;

}

public MesGroup getGroup() {

return group;

}

public void setGroup(MesGroup group) {

this.group = group;

}

public String getUserNo() {

return user.getUserNo();

}

public String getUserID() {

}

public String getUserName() {

return user.getUserName();

}

public MesUser getUser() {

return user;

}

public void setUser(MesUser user) {

this.user = user;

}

}
2.5.5 IdentitySession 实现类

import java.util.Arrays;

import java.util.List;

import org.jbpm.pvm.internal.id.DbidGenerator;

import org.jbpm.pvm.internal.identity.spi.IdentitySession;

/**

@SuppressWarnings("unchecked")

}

public String createH() {

Test t = new Test();

// delete the related memberships

}

// delete the user

session.delete(user);

}

public String createGroup(String groupName, String groupType,

Restrictions.eq("g.id", groupId)).uniqueResult();

session.delete(membership);

}

}
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 class="xxx . Xxx . xxx . MesIdentitySessionImpl">

</object>

</transaction-context>

1.注释掉jbpm4自己的hbm.xml文件

<!--

<import resource="jbpm.identity.cfg.xml" />

-->

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 class="assigned" />

</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="userSex" column="USERSEX_" />  <!-- 性别 -->

<property name="userPassword" column="USERPASSWORD_" />  <!-- 密码 -->

<property name="userType" column="USERTYPE_" />  <!-- 类型 -->

<property name="userMail" column="USERMAIL_" />  <!-- 电子邮件 -->

<property name="signaturePic" column="SIGNATUREPIC_" /> <!-- 电子签名 -->

<property name="remarks" column="REMARKS_" /> <!-- 备注 -->

</class>



<!-- ### MEMBERSHIP ##################################################### -->

<class name="com.t.MesGroupMember" table="JBPM4_CUSTOMIZE_MEMBERSHIP">

<id name="dbid" column="DBID_">

<generator class="assigned" />

</id>

<version name="dbversion" column="DBVERSION_" />



<many-to-one name="user"

column="USER_"

class="com.t.MesUser"

foreign-key="FK_MEM_USER"

index="IDX_MEM_USER"/>

<!--

<property name="id" column="ID_" />

<property name="groupName" column="NAME_" />

<property name="groupType" column="TYPE_" />

<property name="remarks" column="REMARKS_" />

<many-to-one name="parentGroup"

column="PARENT_"

class="com.t.MesGroup"

foreign-key="FK_GROUP_PARENT"

index="IDX_GROUP_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"));
