2.flowableconfig配置类

package org.fh.config;

import org.flowable.spring.springprocessengineconfiguration;
import org.flowable.spring.boot.engineconfigurationconfigurer;
import org.springframework.context.annotation.configuration;
import org.springframework.stereotype.controller;

/**
 * 说明：flowable配置
 * 作者：fh admin
 * from：fhadmin.cn
 */
@controller
@configuration
public class flowableconfig implements engineconfigurationconfigurer<springprocessengineconfiguration> {
    
    @override
    public void configure(springprocessengineconfiguration engineconfiguration) {
        engineconfiguration.setactivityfontname("宋体");
        engineconfiguration.setlabelfontname("宋体");
        engineconfiguration.setannotationfontname("宋体");
    }
    
}
3.重写 securityutils 重构流程编辑器获取用户信息

package org.flowable.ui.common.security;

import org.fh.util.jurisdiction;
import org.flowable.common.engine.api.flowableillegalstateexception;
import org.flowable.idm.api.user;
import org.flowable.ui.common.model.remoteuser;
import org.springframework.security.core.authentication;
import org.springframework.security.core.context.securitycontext;
import org.springframework.security.core.context.securitycontextholder;

import java.util.arraylist;
import java.util.list;

/**
 * 说明：重构流程编辑器获取用户信息
 * 作者：fh admin
 * from：fhadmin.cn
 */
public class securityutils {

    private static user assumeuser;
    
    private static securityscopeprovider securityscopeprovider = new flowablesecurityscopeprovider();

    private securityutils() {
    }

    /**
     * get the login of the current user.
     */
    public static string getcurrentuserid() {
        user user = getcurrentuserobject();
        if (user != null) {
            return user.getid();
        }
        return null;
    }

    /**
     * @return the {@link user} object associated with the current logged in user.
     */
    public static user getcurrentuserobject() {
        if (assumeuser != null) {
            return assumeuser;
        }

        remoteuser user = new remoteuser();
        user.setid(jurisdiction.getusername());
        user.setdisplayname(jurisdiction.getname());
        user.setfirstname(jurisdiction.getname());
        user.setlastname(jurisdiction.getname());
        user.setemail("admin@flowable.com");
        user.setpassword("123456");
        list<string> pris = new arraylist<>();
        pris.add(defaultprivileges.access_modeler);
        pris.add(defaultprivileges.access_idm);
        pris.add(defaultprivileges.access_admin);
        pris.add(defaultprivileges.access_task);
        pris.add(defaultprivileges.access_rest_api);
        user.setprivileges(pris);
        return user;
    }
    
    public static void setsecurityscopeprovider(securityscopeprovider securityscopeprovider) {
        securityutils.securityscopeprovider = securityscopeprovider;
    }

    public static securityscope getcurrentsecurityscope() {
        securitycontext securitycontext = securitycontextholder.getcontext();
        if (securitycontext != null && securitycontext.getauthentication() != null) {
            return getsecurityscope(securitycontext.getauthentication());
        }
        return null;
    }

    public static securityscope getsecurityscope(authentication authentication) {
        return securityscopeprovider.getsecurityscope(authentication);
    }

    public static securityscope getauthenticatedsecurityscope() {
        securityscope currentsecurityscope = getcurrentsecurityscope();
        if (currentsecurityscope != null) {
            return currentsecurityscope;
        }
        throw new flowableillegalstateexception("user is not authenticated");
    }

    public static void assumeuser(user user) {
        assumeuser = user;
    }

    public static void clearassumeuser() {
        assumeuser = null;
    }
}

工作流模块—————-www.fhadmin.cn—————

1.模型管理：web在线流程设计器、导入导出xml、复制流程、部署流程

2.流程管理：导入导出流程资源文件、查看流程图、根据流程实例反射出流程模型、激活挂起

3.运行中流程：查看流程信息、当前任务节点、当前流程图、作废暂停流程、指派待办人、自由跳转

4.历史的流程：查看流程信息、流程用时、流程状态、查看任务发起人信息

5.待办任务：查看本人个人任务以及本角色下的任务、办理、驳回、作废、指派一下代理人

6.已办任务：查看自己办理过的任务以及流程信息、流程图、流程状态(作废 驳回 正常完成)

办理任务时候可以选择用户进行抄送，就是给被抄送人发送站内信通知当前审批意见以及备注信息

注：当办理完当前任务时，下一任务待办人会即时通讯收到新任务消息提醒，当作废和完结任务时,任务发起人会收到站内信消息通知
