SpringBoot下的工作流Activiti开发

發布時間：2025/5/22 javascript 24 豆豆

生活随笔收集整理的這篇文章主要介紹了 SpringBoot下的工作流Activiti开发小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1.準備pom.xml

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"

? ? ? ? ?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

? ? ? ? ?xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

? ? ? ? <artifactId>spring-boot-starter-parent</artifactId>

? ? ? ? <version>2.0.2.RELEASE</version>

? ? ? ? <relativePath/>

? ? </parent>

? ? <properties>

? ? ? ? <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

? ? ? ? <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

? ? ? ? <java.version>1.8</java.version>

? ? </properties>

? ? ? ? ? ? </plugin>

? ? ? ? </plugins>

? ? </build>

</project>

-----------------------------------------------------------------------------------------------------------------------

2.準備流程文件one-task-process.bpmn20.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

? ? <process id="leave1" isClosed="false" isExecutable="true" processType="None">

? ? ? ? <startEvent id="_2" name="start"/>

? ? ? ? <userTask activiti:assignee="${leave.userId}" activiti:exclusive="true" id="_3" name="submit"/>

? ? ? ? <exclusiveGateway gatewayDirection="Unspecified" id="_4" name="result"/>

? ? ? ? <userTask activiti:assignee="${leave.approver1}" activiti:exclusive="true" id="_5" name="approve1"/>

? ? ? ? <exclusiveGateway gatewayDirection="Unspecified" id="_6" name="result"/>

? ? ? ? <userTask activiti:assignee="${leave.approver2}" activiti:exclusive="true" id="_7" name="approve2"/>

? ? ? ? <exclusiveGateway gatewayDirection="Unspecified" id="_8" name="result"/>

? ? ? ? <endEvent id="_9" name="end"/>

? ? ? ? <sequenceFlow id="_10" sourceRef="_2" targetRef="_3"/>

? ? ? ? <sequenceFlow id="_11" sourceRef="_3" targetRef="_4"/>

? ? ? ? <sequenceFlow id="_12" name="y" sourceRef="_4" targetRef="_5">

? ? ? ? ? ? <conditionExpression xsi:type="tFormalExpression"><![CDATA[${leave.submit==true}]]></conditionExpression>

? ? ? ? </sequenceFlow>

? ? ? ? <sequenceFlow id="_13" name="n" sourceRef="_4" targetRef="_9">

? ? ? ? ? ? <conditionExpression xsi:type="tFormalExpression"><![CDATA[${leave.submit==false}]]></conditionExpression>

? ? ? ? </sequenceFlow>

? ? ? ? <sequenceFlow id="_14" sourceRef="_5" targetRef="_6"/>

? ? ? ? <sequenceFlow id="_15" name="n" sourceRef="_6" targetRef="_7">

? ? ? ? ? ? <conditionExpression xsi:type="tFormalExpression"><![CDATA[${leave.agree1==true}]]></conditionExpression>

? ? ? ? </sequenceFlow>

? ? ? ? <sequenceFlow id="_16" sourceRef="_7" targetRef="_8"/>

? ? ? ? <sequenceFlow id="_17" name="y" sourceRef="_6" targetRef="_3">

? ? ? ? ? ? <conditionExpression xsi:type="tFormalExpression"><![CDATA[${leave.agree1==false}]]></conditionExpression>

? ? ? ? </sequenceFlow>

? ? ? ? <sequenceFlow id="_18" name="n" sourceRef="_8" targetRef="_3">

? ? ? ? ? ? <conditionExpression xsi:type="tFormalExpression"><![CDATA[${leave.agree2==false}]]></conditionExpression>

? ? ? ? </sequenceFlow>

? ? ? ? <sequenceFlow id="_19" name="y" sourceRef="_8" targetRef="_9">

? ? ? ? ? ? <conditionExpression xsi:type="tFormalExpression"><![CDATA[${leave.agree2==true}]]></conditionExpression>

? ? ? ? </sequenceFlow>

? ? </process>

</definitions>

-----------------------------------------------------------------------------------------------------------------------

3.準備SpringBoot屬性文件application.properties

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/xh_activiti?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false&autoReconnect=true&failOverReadOnly=false&useUnicode=true&characterEncoding=UTF-8

spring.datasource.username=root

spring.datasource.password=123456

spring.jpa.properties.hibernate.hbm2ddl.auto=update

spring.jpa.show-sql=true

server.port=8082

server.tomcat.uri-encoding=UTF-8

spring.activiti.history-level=full

spring.activiti.database-schema-update=true

spring.activiti.check-process-definitions=false

-----------------------------------------------------------------------------------------------------------------------

4.實體類

包名：com.springboot.demo.domain

類名：Leave

實現：

package com.springboot.demo.domain;

import lombok.Data;

import java.io.Serializable;

import java.util.Date;

/**

?* @ClassName Leave

?* @Description TODO

?* @Author yunshuodeng

?* @Date 2019-05-05 15:47

?* @Version 1.0

?**/

@Data

public class Leave implements Serializable {

? ? private String userId;

? ? private Boolean submit;

? ? private String startDate;

? ? private String endDate;

? ? private float totalDay;

? ? private String desc;

? ? private String taskId;

? ? ? ? ? ? }

? ? ? ? }

? ? ? ? Map<String, Object> resultMap = new HashMap<>();

6.啟動應用，并按如下順序進行訪問

1）啟動流程

訪問地址：http://localhost:8082/level/v1/start?userId=10

返回結果：{"processId":"10001"}

2）填寫請假單申請

訪問地址：http://localhost:8082/level/v1/apply

參數列表：

{

"desc":"測試",

"startDate":"2019-05-05",

"endDate":"2019-05-09",

"totalDay":4,

"approver1":11,

"approver2":12,

"submit":true,

"processId":"10001"

}

返回結果：

{

? ? "taskId": "10010"

}

3）查看流程中待辦任務列表

訪問地址：http://localhost:8082/level/v1/find?userId=11

返回結果：{"datas":[{"userId":"10","submit":true,"startDate":"2019-05-05","endDate":"2019-05-09","totalDay":4.0,"desc":"測試","taskId":"10016","taskName":"approve1","approver1":"11","agree1":null,"approveDesc1":null,"approver2":"12","agree2":null,"approveDesc2":null,"processId":null}]}

4）直接領導審批

訪問地址：http://localhost:8082/level/v1/approve1

請求參數：

{

"taskId":10016,

"approveDesc1":"同意",

"agree1":true

}

返回結果：{

? ? "taskId": "10016"

}

5）部門領導審批

查看流程中待辦任務列表

訪問地址：http://localhost:8082/level/v1/find?userId=12

返回結果：

{"datas":[{"userId":"10","submit":true,"startDate":"2019-05-05","endDate":"2019-05-09","totalDay":4.0,"desc":"測試","taskId":"10022","taskName":"approve2","approver1":"11","agree1":true,"approveDesc1":"同意","approver2":"12","agree2":null,"approveDesc2":null,"processId":null}]}

執行審批操作

訪問地址：http://localhost:8082/level/v1/approve2

請求參數：

{

"taskId":10022,

"approveDesc2":"同意",

"agree2":true

}

返回結果：

{

? ? "taskId": "10022"

}
