Springboot整合Flowable【查阅众多资料,功能完整,亲身验证】

本文主要是介绍Springboot整合Flowable【查阅众多资料,功能完整,亲身验证】，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、搭建一个基于maven的基础框架

1.环境说明:JDK11、Mysql8

2.项目结构概览:

二、项目相关代码及配置

1.pom.xml配置

<?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>sdata.ops.platform</groupId><artifactId>flowable</artifactId><version>1.0-SNAPSHOT</version><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.1</version><relativePath/> <!-- lookup parent from repository --></parent><properties><maven.compiler.source>11</maven.compiler.source><maven.compiler.target>11</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><!--Springboot项目自带 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--Springboot Web项目 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!--lombok --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.22</version></dependency><!-- idm依赖提供身份认证 --><dependency><groupId>org.flowable</groupId><artifactId>flowable-spring-boot-starter-ui-idm</artifactId><version>6.7.1</version></dependency><!-- modeler绘制流程图 --><dependency><groupId>org.flowable</groupId><artifactId>flowable-spring-boot-starter-ui-modeler</artifactId><version>6.7.1</version></dependency><!-- jpa --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jpa</artifactId></dependency><!-- mysql驱动 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><!-- flowable --><dependency><groupId>org.flowable</groupId><artifactId>flowable-spring-boot-starter</artifactId><version>6.7.1</version></dependency></dependencies>
</project>

2.application.yml配置

server:port: 8088flowable:idm:app:admin:# 登录的用户名user-id: admin# 登录的密码password: admin# 用户的名字first-name: *last-name: **
spring:# mysql连接信息datasource:# mysql8之后driver-class-name: com.mysql.cj.jdbc.Driver# mysql8之前#    driver-class-name: com.mysql.jdbc.Driverurl: jdbc:mysql://localhost:3306/flowable?useUnicode=true&characterEncoding=utf8&tinyInt1isBit=false&useSSL=false&serverTimezone=GMT&nullCatalogMeansCurrent=trueusername: rootpassword: rootjpa:properties:hibernate:hbm2ddl:auto: updatedialect: org.hibernate.dialect.MySQL5InnoDBDialectopen-in-view: true

3.流程引擎配置文件flowable.cfg.xml

<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://localhost:3306/flowable?useUnicode=true&amp;characterEncoding=utf8&amp;tinyInt1isBit=false&amp;useSSL=false&amp;serverTimezone=GMT&amp;nullCatalogMeansCurrent=true" /><property name="jdbcDriver" value="com.mysql.cj.jdbc.Driver" /><property name="jdbcUsername" value="root" /><property name="jdbcPassword" value="root" /><property name="databaseSchemaUpdate" value="true" /><property name="asyncExecutorActivate" value="false" /></bean></beans>

4.log4j.properties配置

log4j.rootLogger=DEBUG, CA
log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern= %d{hh:mm:ss,SSS} [%t] %-5p %c %x - %m%n

5.启动类JavaSkillPointApplication

package sdata;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class JavaSkillPointApplication {public static void main(String[] args) {SpringApplication.run(JavaSkillPointApplication.class, args);}}

6.TestController
