2.数据库

Flowable 默认使用 H2 数据库,但是可以通过修改配置文件来指定,本文使用的是 Postgres
创建一个名为 flowable 的库
Flowable 首次启动时默认会自动创建表
也可以通过官方SQL脚本手动创建表

在这里插入图片描述

3.资源文件

4.BPMN 流程图绘制插件

IDEA 插件:Flowable BPMN visualizer

安装好该插件后即可在 IDEA 中通过右键创建流程模板了

在这里插入图片描述

右键可以创建不同节点

在这里插入图片描述

右键用该插件打开上面 bpmn 配置文件,如下图,本配置包含了大部分 Flowable节点的简单测试实现

在这里插入图片描述

5.测试代码

1.启动类

package org.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


@SpringBootApplication
public class WflApp {

    public static void main(String[] args) {
        SpringApplication.run(WflApp.class,args);
        System.out.println("Hello world!");
    }
}

2.Flowable 配置

package org.example.config;

import org.example.exp.external.MyExternalWorker;
import org.flowable.common.engine.impl.EngineDeployer;
import org.flowable.common.engine.impl.history.HistoryLevel;
import org.flowable.dmn.engine.deployer.DmnDeployer;
import org.flowable.engine.impl.rules.RulesDeployer;
import org.flowable.job.service.JobServiceConfiguration;
import org.flowable.job.service.impl.asyncexecutor.DefaultJobManager;
import org.flowable.spring.SpringProcessEngineConfiguration;
import org.flowable.spring.boot.EngineConfigurationConfigurer;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;

/**
 * @Author zhx & moon
 * @Since 1.8
 * @Date 2024-01-02 下午 6:18
 */
@Configuration
public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {

    @Value("${flowable.async-executor-activate}")
    boolean asyncExecutorActivate;

    @Value("${flowable.history-level}")
    HistoryLevel historyLevel;

    @Override
    public void configure(SpringProcessEngineConfiguration engineConfiguration) {

        //设置字体
        engineConfiguration.setActivityFontName("宋体");
        engineConfiguration.setLabelFontName("宋体");
        engineConfiguration.setAnnotationFontName("宋体");


        //设置 RULE 依赖
        List<EngineDeployer> customPostDeployers = new ArrayList<>();
        customPostDeployers.add(new RulesDeployer());
        customPostDeployers.add(new DmnDeployer());
        engineConfiguration.setCustomPostDeployers(customPostDeployers);

        // JOB 执行器
        engineConfiguration.setAsyncExecutorActivate(asyncExecutorActivate);
        engineConfiguration.setHistoryLevel(historyLevel);

        //设置外部处理器
        engineConfiguration.addCustomJobHandler(new MyExternalWorker());

        //设置 JOB Manger
        String engineName = engineConfiguration.getEngineName();
        JobServiceConfiguration configuration = new JobServiceConfiguration(engineName);
        DefaultJobManager jobManager = new DefaultJobManager(configuration);
        engineConfiguration.setJobManager(jobManager);
    }
}

3.Camel 配置

1.Camel 配置
package org.example.config;

import jakarta.annotation.PostConstruct;
import org.apache.camel.CamelContext;
import org.example.router.CamelRouter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

/**
 * @Author zhx & moon
 * @Since 1.8
 * @Date 2024-01-08 下午 3:06
 */
@Component
public class MyCamelContext {

    @Autowired
    CamelContext camelContext;

    @PostConstruct
    public void init() throws Exception {
        camelContext.addRoutes(new CamelRouter());
        System.out.println();
    }
}

2.Camel Router 定义
package org.example.router;

import org.apache.camel.builder.RouteBuilder;

/**
 * @Author zhx & moon
 * @Since 1.8
 * @Date 2024-01-08 下午 2:26
 */
public class CamelRouter extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        from("flowable://leave_approval_process:sid-bb78a1a1-3bd8-411a-920b-63ae2eb06949")
                .setBody(constant("hello world!"))
                .to("log:output");
    }
}

4.扩展类监听

1.外部工作类
package org.example.exp.external;

import org.flowable.common.engine.api.scope.ScopeTypes;
import org.flowable.common.engine.impl.interceptor.CommandContext;
import org.flowable.engine.impl.bpmn.helper.ErrorPropagation;
import org.flowable.engine.impl.cfg.ProcessEngineConfigurationImpl;
import org.flowable.engine.impl.persistence.entity.ExecutionEntity;
import org.flowable.engine.impl.util.CommandContextUtil;
import org.flowable.engine.impl.util.CountingEntityUtil;
import org.flowable.job.service.JobHandler;
import org.flowable.job.service.impl.persistence.entity.JobEntity;
import org.flowable.variable.api.delegate.VariableScope;
import org.flowable.variable.service.VariableService;
import org.flowable.variable.service.impl.persistence.entity.VariableInstanceEntity;

import java.util.List;

/**
 * @Author zhx & moon
 * @Since 1.8
 * @Date 2024-01-09 上午 10:07
 */
public class MyExternalWorker implements JobHandler {

    /**
     * 自定义实现覆盖默认实现
     */
    private static final String type = "async-continuation";

    /**
     * key 用于获取唯一的处理器 JobHandlers
     * @return
     */
    @Override
    public String getType() {
        return type;
    }

    /**
     * 定义一个异步任务 用于在流程外执行一些处理逻辑 弱关联性
     * @param job
     * @param configuration
     * @param variableScope
     * @param commandContext
     */
    @Override
    public void execute(JobEntity job, String configuration, VariableScope variableScope, CommandContext commandContext) {


        System.out.println("Step12 My External work take ...");

        ExecutionEntity executionEntity = (ExecutionEntity) variableScope;

        ProcessEngineConfigurationImpl processEngineConfiguration = CommandContextUtil.getProcessEngineConfiguration(commandContext);
        VariableService variableService = processEngineConfiguration.getVariableServiceConfiguration().getVariableService();
        List<VariableInstanceEntity> jobVariables = variableService.findVariableInstanceBySubScopeIdAndScopeType(executionEntity.getId(), ScopeTypes.BPMN_EXTERNAL_WORKER);
        for (VariableInstanceEntity jobVariable : jobVariables) {
            executionEntity.setVariable(jobVariable.getName(), jobVariable.getValue());
            CountingEntityUtil.handleDeleteVariableInstanceEntityCount(jobVariable, false);
            variableService.deleteVariableInstance(jobVariable);
        }

        if (configuration != null && configuration.startsWith("error:")) {
            String errorCode;
            if (configuration.length() > 6) {
                errorCode = configuration.substring(6);
            } else {
                errorCode = null;
            }
            ErrorPropagation.propagateError(errorCode, executionEntity);
        } else {
            CommandContextUtil.getAgenda(commandContext).planTriggerExecutionOperation(executionEntity);
        }
    }
}

2.普通Java服务扩展

三.测试

1.测试

创建流实例、查询待审批节点、审批、触发接收节点

输出日志

在这里插入图片描述

2.导出流进度

接口:/flowable-rest/wfl/buildFlowChart?instanceId=0626e0cb-af11-11ee-9530-00155da1d269

在这里插入图片描述
