flowable 的ProcessEngine配置

1 flowable process engine 是通过  flowable.cfg.xml 配置文件配置的。在spring 环境中是使用 flowable-context.xml 配置文件的，

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine() 方法会从 classpath 中寻找配置文件 flowable.cfg.xml 进行创建。


说明：flowable.cfg.xml 配置文件必须包含一个 ID 为processEngineConfiguration 的bean

flowable.cfg.xml 配置文件内容如下

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

  <bean id="processEngineConfiguration" 
      class="org.flowable.engine.impl.cfg.StandaloneProcessEngineConfiguration">

    <property name="jdbcUrl" value="jdbc:mysql://196.131.9.62/flow1?allowMultiQueries=true&amp;useUnicode=true&amp;characterEncoding=UTF-8&amp;useSSL=false" />
    <property name="jdbcDriver" value="com.mysql.jdbc.Driver" />
    <property name="jdbcUsername" value="root" />
    <property name="jdbcPassword" value="123456" />

    <property name="databaseSchemaUpdate" value="true" />

    <property name="asyncExecutorActivate" value="false" />
  </bean>

</beans>

2 将 flowable 与 springboot 集成

2.1 pom 文件如下

<?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">

  </properties>

2.2 application.yml 配置

server:
  port: 8060

spring:
  application:
    name: flow
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/flow2?useUnicode=true&characterEncoding=UTF-8&useSSL=false&zeroDateTimeBehavior=convertToNull
    username: root
    password: root123

      minimum-idle: 3
      connection-timeout: 30000
      maximum-pool-size: 50
      idle-timeout: 60000
flowable:
  #关闭定时任务JOB
  async-executor-activate: false
  database-schema-update: false
  process:

    definition-cache-limit: 100

2.3 获得常用的 service 类BaseService

@Service
public class BaseService {

    @Autowired
    @Getter
    private RepositoryService repositoryService;

    @Autowired
    @Getter
    private RuntimeService runtimeService;

    @Autowired
    @Getter
    private TaskService taskService;

    @Autowired
    @Getter
    private IdmIdentityService idmIdentityService;

    @Getter
    @Autowired
    private HistoryService historyService;

    @Autowired
    @Getter
    private ManagementService managementService;

}
