activiti5.17使用自定义的user和group表的几种方法

一、不使用原有的表

1、在spring.xml里添加：

<list>

</list>

</property>

2、用户管理工厂类CustomUserEntityManagerFactory.java：

public Session openSession() {
            // 返回自定义的UserManager实例 return userEntityManager;
        }
    }

3、组管理工厂类CustomGroupEntityManagerFactory.java:

package com.gs.workflow.util;
    
    import org.activiti.engine.impl.interceptor.Session;
    import org.activiti.engine.impl.interceptor.SessionFactory;
    import org.activiti.engine.impl.persistence.entity.GroupEntityManager;
    import org.springframework.beans.factory.annotation.Autowired;
    
    /** * Created by gj.hu on 2015/8/24. */ public class CustomGroupEntityManagerFactory implements SessionFactory{
        private GroupEntityManager groupEntityManager;
    
        @Autowired
        public void setGroupEntityManager(GroupEntityManager groupEntityManager) {
            this.groupEntityManager = groupEntityManager;
        }
    
        public Class<?> getSessionType() {
            // 返回原始的GroupEntityManager类型 return GroupEntityManager.class;
        }
    
        public Session openSession() {
            // 返回自定义的GroupEntityManager实例 return groupEntityManager;
        }
    }
     4、覆盖用户管理类CustomUserEntityManager.java   @Service  public class CustomUserEntityManager extends UserEntityManager{
        private static final Log logger = LogFactory
                .getLog(CustomUserEntityManager.class);
    
        @Autowired
        private UserManager userManager;//自己实现的获取用户数据的Service
    
        @Override
        public UserEntity findUserById(final String userCode) {
            if (userCode == null)
                return null;
    
            try {
                UserEntity userEntity = null;
                com.gs.entity.User bUser = userManager.getUser(Long.valueOf(userCode));
                userEntity = ActivitiUtils.toActivitiUser(bUser);
                return userEntity;
            } catch (EmptyResultDataAccessException e) {
                return null;
            }
        }
    
        @Override
        public List<Group> findGroupsByUser(final String userCode) {
            if (userCode == null)
                return null;
    
            List<com.gs.entity.Group> bGroups = userManager.getUser(Long.valueOf(userCode)).getGroupList();
    
            List<Group> gs = null;
            gs = ActivitiUtils.toActivitiGroups(bGroups);
            return gs;
    
        }
    
        @Override
        public List<User> findUserByQueryCriteria(UserQueryImpl query, Page page) {
            throw new RuntimeException("not implement method.");
        }
    
        @Override
        public IdentityInfoEntity findUserInfoByUserIdAndKey(String userId,
                                                             String key) {
            throw new RuntimeException("not implement method.");
        }
    
        @Override
        public List<String> findUserInfoKeysByUserIdAndType(String userId,
                                                            String type) {
            throw new RuntimeException("not implement method.");
        }
    
        @Override
        public long findUserCountByQueryCriteria(UserQueryImpl query) {
            throw new RuntimeException("not implement method.");
        }
    }
     5、覆盖组管理类CustomGroupEntityManager.java:  @Service
    public class CustomGroupEntityManager extends GroupEntityManager {
        private static final Log logger = LogFactory
                .getLog(CustomGroupEntityManager.class);
    
        @Autowired
        private GroupManager groupManager;
    
        @Override
        public GroupEntity findGroupById(final String groupCode) {
            if (groupCode == null)
                return null;
    
            try {
                com.sanshen.js.entity.account.Group bGroup = groupManager.getGroupByGroupId(groupCode);
    
                GroupEntity e = new GroupEntity();
                e.setRevision(1);
    
                // activiti有3种预定义的组类型：security-role、assignment、user // 如果使用Activiti // Explorer，需要security-role才能看到manage页签，需要assignment才能claim任务 e.setType("assignment");
    
                e.setId(bGroup.getGroupId());
                e.setName(bGroup.getName());
                return e;
            } catch (EmptyResultDataAccessException e) {
                return null;
            }
    
        }
    
        @Override
        public List<Group> findGroupsByUser(final String userCode) {
            if (userCode == null)
                return null;
    
            List<com.sanshen.js.entity.account.Group> bGroupList = groupManager.getUser(Long.valueOf(userCode)).getGroupList();
    
            List<Group> gs = new ArrayList<Group>();
            GroupEntity g;
            for (com.sanshen.js.entity.account.Group bGroup : bGroupList) {
                g = new GroupEntity();
                g.setRevision(1);
                g.setType("assignment");
    
                g.setId(bGroup.getGroupId());
                g.setName(bGroup.getName());
                gs.add(g);
            }
            return gs;
        }
    
        @Override
        public List<Group> findGroupByQueryCriteria(GroupQueryImpl query, Page page) {
            throw new RuntimeException("not implement method.");
        }
    
        @Override
        public long findGroupCountByQueryCriteria(GroupQueryImpl query) {
            throw new RuntimeException("not implement method.");
        }
    }      参考：http://124444154-qq-com.iteye.com/blog/1830995 二、调用IdentifyService接口完成同步     参考：http://blog.csdn.net/szwangdf/article/details/25640357 三、覆盖IdentifyService接口实现：一个一个覆盖就行了 四、用视图覆盖同名的ACT_ID_*表：      1、必须先删除ACT_ID_*表      2、分别创建同名视图 DROP VIEW IF EXISTS act_id_membership;  
    DROP VIEW IF EXISTS act_id_user;  
    DROP VIEW IF EXISTS act_id_group;
    
    CREATE or replace VIEW act_id_user(ID_,REV_,FIRST_,LAST_,EMAIL_,PWD_,PICTURE_ID_ ,CONSTRAINT id_pk PRIMARY KEY(ID_) RELY DISABLE NOVALIDATE) AS SELECT TO_CHAR(au.login_name) AS ID_, 0 AS REV_, to_char(au.user_name_cn) AS FIRST_, '' AS LAST_, to_char(au.email) AS EMAIL_, to_char(au.PASSWORD) AS PWD_, '' AS PICTURE_ID_ FROM base_user au;  
      
    CREATE VIEW act_id_group AS SELECT ar.name AS ID_, NULL AS REV_, ar.name AS NAME_, 'assignment' AS TYPE_ FROM s_role ar;  
      
    CREATE VIEW act_id_membership AS SELECT (SELECT u.username FROM s_user u WHERE u.id=ur.user_id) AS USER_ID_, (SELECT r.name FROM s_role r WHERE r.id=ur.role_id) AS GROUP_ID_ FROM s_user_role ur;
     创建的视图要保证数据类型一致，例如用户的ACT_ID_MEMBERSHIP表的两个字段都是字符型，一般系统中都是用NU MBER作为用户、角色的主键类型，所以创建视图的时候要把数字类型转换为字符型。
     3、在spring.xml里添加： 
         
          
           < bean id = "processEngineConfiguration" class = "org.activiti.spring.SpringProcessEngineConfiguration" >      ...      < property name = "dbIdentityUsed" value = "false" >      ... </ property ></ bean >
