Activiti6.0学习实践（3）-应用工程（helloworld）构建

妖狐艹你老母 2023-06-24 15:27 24阅读 0赞

本章主要是通过构建一个流程应用，来了解通过idea来创建流程图和编写代码来创建一个流程应用。

**目录**

1、IDEA安装插件actiBPM

2、创建一个maven工程

3、创建BPMN流程图

3.1 创建一个BPMN 流程

3.2 修改元素的名称

4、BPMN定义文件xml化

5、修改pom文件添加依赖

6、创建应用入口DemoMain类

7、测试验证

8、问题处理小结

8.1、Idea工程报错， write-unsafe

8.2、流程定义获取name乱码

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

# 1、**IDEA安装插件actiBPM** #

启动idea，通过 File-setting 找到 plugins项目

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70][]

点击安装，安装完成后根据提示重启IDEA。

# 2、**创建一个maven工程** #

接下来，我们需要创建一个新的maven工程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 3][]

# 3、**创建BPMN流程图** #

下面我们通过这个工程创建一个二级审批流程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 4][]

## 3.1 **创建一个BPMN 流程** ##

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 5][]

下面我们就可以在这个界面上画流程图了（话说这个界面槽点多多）

我们要画的流程是一个二级审批流程：

开始--员工填写请假流程--部门主管审批—人力审批—结束

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 6][]

## 3.2 **修改元素的名称** ##

对每个元素进行修改名称，修改后的内容如下图所示

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 7][]

设定属性： form Property中的 id， name， type

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 8][]

注意上图中的类型后面实践中证明是错误的，只要都用小写就好，否则会报错误。（string， date等）

好，流程的配置到这里，暂时先放一下，我们回到工程

# **4、BPMN定义文件xml化** #

将我们设计的BPMN定义文件，复制，复制的时候重命名，通常是在后面增加20.xml。 20表示遵循BPMN2.0规范，重命名后，可以直接打开xml查看，和我们熟知的xml文档没有什么差别。

![20191224085722134.png][]

下面是本例中xml内容：

# 5、**修改pom文件添加依赖** #

在pom文件中，添加我们这工程的依赖，具体见如下pom.xml文件

<?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">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>com.study.myactiviti</groupId>
        <artifactId>myactiviti-app</artifactId>
        <version>1.0-SNAPSHOT</version>
    
        <dependencies>
            <dependency>
                <groupId>org.activiti</groupId>
                <artifactId>activiti-engine</artifactId>
                <version>6.0.0</version>
            </dependency>
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <version>4.11</version>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>ch.qos.logback</groupId>
                <artifactId>logback-classic</artifactId>
                <version>1.2.3</version>
            </dependency>
            <dependency>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
                <version>25.0-jre</version>
            </dependency>
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>5.1.45</version>
            </dependency>
        </dependencies>
    
    </project>

# 6、**创建应用入口DemoMain类** #

在入口类中，我们要实现整个流程引擎应用的串联。因此应用需要如下几个步骤

1.  创建流程引擎

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 9][]

2. 部署流程定义文件xml

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 10][]    3、启动流程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 11][]

4、处理流程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 12][]

这一步主要是获取任务列表，并获取任务中的表单属性，对表单属性进行处理。上面代码中引入了scanner进行命令式交互。

完成代码见下面：

package com.study.activiti;
    
    import com.google.common.collect.Maps;
    import org.activiti.engine.*;
    import org.activiti.engine.form.FormProperty;
    import org.activiti.engine.form.TaskFormData;
    import org.activiti.engine.impl.form.DateFormType;
    import org.activiti.engine.impl.form.StringFormType;
    import org.activiti.engine.repository.Deployment;
    import org.activiti.engine.repository.DeploymentBuilder;
    import org.activiti.engine.repository.ProcessDefinition;
    import org.activiti.engine.runtime.ProcessInstance;
    import org.activiti.engine.task.Task;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    import java.text.ParseException;
    import java.text.SimpleDateFormat;
    import java.util.Date;
    import java.util.HashMap;
    import java.util.List;
    import java.util.Scanner;
    
    /**
     * Describe:启动类
     *
     * @author cwqsolo
     * @date 2019/12/17
     */
    public class DemoMain {
    
        private static final Logger LOGGER = LoggerFactory.getLogger(DemoMain.class);
    
        public static void main(String[] args) throws ParseException {
            LOGGER.info("启动应用------>>>");
    
            //步骤1--创建流程引擎
            ProcessEngine processEngine = getProcessEngine();

# 7、**测试验证** #

下面将我们的demo应用跑起来，则会一步一步进行任务处理，在每个任务界面进行表单内容的输入

# **8、问题处理小结** #

## **8.1、Idea工程报错， write-unsafe** ##

问题描述：系统报write-unsafe错误，不过不影响工程。

解决：

修改idea的启动参数，即在下图红框处文件中，在最后添加-Dfile.encoding=UTF-8

## 8.2、**流程定义获取name乱码** ##

问题描述：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Nzb2xv_size_16_color_FFFFFF_t_70 16][]

解决：

检查数据库中记录，发现也是乱码，推断是入数据库就出问题。检查发现mysql的url没有配置字符集，增加UTF-8配置，如下图红框，问题解决
