二级审批流程的实现

1.设计一个二级审批流程

2.创建三个不同用户组为流程参与者

3.参与者协同完成流程

 

 

second_approve.bpmn 设计

 

对应xml文件如下

使用springboot打包

更新pom.xml

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.RELEASE</version>
        <relativePath/>
    </parent>


    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>   <!-- 基于plugin启动这个程序 -->
            </plugin>
        </plugins>
    </build>

在<dependencies></dependencies>中添加spring-boot的依赖

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

进入这个项目目录，然后输入  mvn package  ，就可以将项目打包：mvn package

target目录中，可以看到两个jar包：

直接使用以下指令来执行我们编译好的二级审批流程文件

java-jar xxxxxx.jar

 

 

将二级审批流程创建archetype脚手架

打开源码目录 Activiti-6.x\tooling\archetypes\activiti-archetype-unittest

安装脚手架 mvn clean install

copy activiti-archetype-unittest2

修改pom.xml中的 artifactId

创建main/java与main/resources两个目录

修改Main.java中的package，后面路径改为 ${package}; package ${package}

修改 META-INF/maven/archetype-metadata.xml

 1  <?xml version="1.0" encoding="UTF-8"?>
 2   <archetype-descriptor name="activiti-archetype-unittest2">
 3     <fileSets>
 4       <fileSet filtered="true" packaged="true">   <!-- filtered是否过滤，packaged：是否经过包结构过滤 -->
 5         <directory>src/main/java</directory>
 6         <includes>
 7           <include>**/*.java</include>
 8        </includes>
 9       </fileSet>
10      <fileSet filtered="false" packaged="false">
11        <directory>src/main/resources</directory>   <!-- 资源目录下面的三个文件 -->
12        <includes>
13          <include>activiti.cfg.xml</include>
14          <include>LeaveProcess.bpmn20.xml</include>
15         <include>logback.xml</include>
16       </includes>
17    </fileSet>
18    <fileSet filtered="true" packaged="true">
19        <directory>src/test/java</directory>
20       <includes>
21         <include>**/*.java</include>
22        </includes>
23      </fileSet>
24      <fileSet filtered="true" packaged="true">
25        <directory>src/test/resources</directory>
26        <includes>
27         <include>second_approve.bpmn20.xml</include>
28       </includes>
29      </fileSet>
30  
31   </fileSets>
32  </archetype-descriptor>

进入activiti-archetype-unittest2的路径下，执行 mvn clean install

在本地的maven仓库中已经创建好的脚手架

Create from archetype后Add Archetype

GroupId org.activiti

ArtifactId activiti-archetype-unittest2

Version 6.0.0

即可继续创建工程

 

 

完
