JBPM4.3总结三
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) {

}
public void setUserNo(String userNo) {

}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {

}
public String getUserSex() {

}
public String getIsValid() {

}
public void setIsValid(String 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;
}
/**

* @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) {

}
public long getDbid() {

}
public void setDbid(long dbid) {

}
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() {

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() {

}
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

}
// delete the user

}

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="userType" column="USERTYPE_" /> <!-- 类型 -->
<property name="userMail" column="USERMAIL_" /> <!-- 电子邮件
-->
<property name="signaturePic" column="SIGNATUREPIC_" /> <!--

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

<class name="com.t.MesGroupMember"

<many-to-one name="user"

column="PARENT_"

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"));
