十六、模块集成流程审批

程序员文章站 2022-06-28 19:04:39
ERP系统中流程审批是必需的模块，流程审批需要工作流的支持，工作流实现企业业务流程重组（BPR）与系统解耦合，工作流产品有很多，国内的工作流产品比较适合国内项目的业务，国外开源的工作流更接近于标准WfMC，对国内复杂的业务支持不够灵活。通常情况软件公司都会开放适合自己的工作流模块，以适应项目开发。我们开发流程审批也是使用自己开发的流程引擎，流程的定义工具现在没有提供，需要手工配置XML流程模块。......

ERP系统中流程审批是必需的模块，流程审批需要工作流的支持，工作流实现企业业务流程重组（BPR）与系统解耦合，工作流产品有很多，国内的工作流产品比较适合国内项目的业务，国外开源的工作流更接近于标准WfMC，对国内复杂的业务支持不够灵活。通常情况软件公司都会开放适合自己的工作流模块，以适应项目开发。我们开发流程审批也是使用自己开发的流程引擎，流程的定义工具现在没有提供，需要手工配置XML流程模块。

工作流引擎关键接口

启动流程
startWorkflow(processId,startUserId,nextUser.getId(),instanceid,type,
						title,nexttask,url,hmap,flag,testMode);
提交流程
wapi.submitWorkflow(instprocessid,instactivityid,instworkitemid,userIdLst,instanceid,
						type,title,nexttask,url,hmap,flag,testMode);
获取代办列表
getWorkitemList(user.getId(), testMode);

工作流模板

<?xml version="1.0" encoding="gb2312"?>
<!--
注意:
流程触发外部接口,其类加载器必须位于工作流引擎类加载器平级或者更高一级

模块实体类

package com.gf.model;

import java.io.Serializable;
import java.math.BigDecimal;

import com.baomidou.mybatisplus.annotations.TableField;
import com.baomidou.mybatisplus.annotations.TableId;
import com.baomidou.mybatisplus.annotations.TableName;
import com.baomidou.mybatisplus.enums.IdType;

@TableName("gf_expense")
public class ExpenseInfo implements Serializable{
	@TableId
	private String id = null;
	private String name = null;
	private String company = null;
	private String bank = null;
	private String bankAccount = null;
	private BigDecimal amount = null;
	private String userId = null;
	@TableField(exist=false)
	private String userName = null;
	
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getCompany() {
		return company;
	}
	public void setCompany(String company) {

	}	
}

SQL

create table gf_expense(id varchar(32),
	name varchar(100),
	company varchar(100),
	bank varchar(100),
	bankaccount varchar(100),
	amount decimal(10,2),
	userId varchar(100)
);

使用Mybatis-Plus操作数据

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
	PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
	"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.gf.mapper.ExpenseMapper">

</mapper>

package com.gf.mapper;

import org.apache.ibatis.annotations.Mapper;

import com.baomidou.mybatisplus.mapper.BaseMapper;
import com.gf.model.ExpenseInfo;

@Mapper
public interface ExpenseMapper extends BaseMapper<ExpenseInfo>{

}


package com.gf.service;

import com.baomidou.mybatisplus.service.IService;
import com.gf.model.ExpenseInfo;

public interface ExpenseService extends IService<ExpenseInfo>{

}


package com.gf.service.impl;

import org.springframework.stereotype.Service;

import com.baomidou.mybatisplus.service.impl.ServiceImpl;
import com.gf.mapper.ExpenseMapper;
import com.gf.model.ExpenseInfo;
import com.gf.service.ExpenseService;

@Service
public class ExpenseServiceImpl extends ServiceImpl<ExpenseMapper,ExpenseInfo>
	implements ExpenseService
{

}

模块Controller集成工作流引擎
