SpringBoot整合Flowable

1. 引入依赖

flowable-spring-boot-starter-basic

<dependency>    <groupId>org.flowable</groupId>    <artifactId>flowable-spring-boot-starter-basic</artifactId>    <version>${flowable.version}</version></dependency>

完整pom

<parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>2.1.16.RELEASE</version>    <relativePath/> <!-- lookup parent from repository --></parent><properties>    <java.version>1.8</java.version>    <flowable.version>6.4.2</flowable.version>    <slf4j.version>1.7.25</slf4j.version></properties><dependencies>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-web</artifactId>    </dependency>    <dependency>        <groupId>org.mybatis.spring.boot</groupId>        <artifactId>mybatis-spring-boot-starter</artifactId>        <version>2.1.4</version>    </dependency>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-devtools</artifactId>        <scope>runtime</scope>        <optional>true</optional>    </dependency>    <dependency>        <groupId>mysql</groupId>        <artifactId>mysql-connector-java</artifactId>        <scope>runtime</scope>    </dependency>    <dependency>        <groupId>org.projectlombok</groupId>        <artifactId>lombok</artifactId>        <optional>true</optional>    </dependency>    <dependency>        <groupId>org.flowable</groupId>        <artifactId>flowable-spring-boot-starter-basic</artifactId>        <version>${flowable.version}</version>    </dependency>    <dependency>        <groupId>com.alibaba</groupId>        <artifactId>druid-spring-boot-starter</artifactId>        <version>1.1.10</version>    </dependency>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-test</artifactId>        <scope>test</scope>        <exclusions>            <exclusion>                <groupId>org.junit.vintage</groupId>                <artifactId>junit-vintage-engine</artifactId>            </exclusion>        </exclusions>    </dependency>    <dependency>        <groupId>org.slf4j</groupId>        <artifactId>slf4j-api</artifactId>        <version>${slf4j.version}</version>    </dependency>    <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-log4j12 -->    <dependency>        <groupId>org.slf4j</groupId>        <artifactId>slf4j-log4j12</artifactId>        <version>${slf4j.version}</version>    </dependency></dependencies>

2. 配置文件

application.properties 主要配置数据源

server.port=10000server.servlet.context-path=/spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driverspring.datasource.url=jdbc:mysql://127.0.0.1:3306/flowable-springboot?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai&nullCatalogMeansCurrent=true&useSSL=falsespring.datasource.username=rootspring.datasource.password=123456# druid configspring.datasource.druid.initial-size=5spring.datasource.druid.min-idle=5spring.datasource.druid.max-active=20spring.datasource.druid.max-wait=60000spring.datasource.druid.time-between-eviction-runs-millis=60000spring.datasource.druid.min-evictable-idle-time-millis=300000spring.datasource.druid.validation-query=SELECT 1 FROM DUALspring.datasource.druid.test-while-idle=truespring.datasource.druid.test-on-return=falsespring.datasource.druid.test-on-borrow=falsespring.datasource.druid.pool-prepared-statements=truespring.datasource.druid.max-pool-prepared-statement-per-connection-size=20spring.datasource.druid.filters=stat,wall,log4jspring.datasource.druid.connection-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

3. 启动查看数据库

启动时，默认会获取 classpath*:/processes/下的所有.bpmn20.xml, .bpmn文件，并完成部署。

查看数据库，表已经自动创建。

4. 设置流程文件位置

设置流程文件位置并在启动时完成部署；

查看 org.flowable.spring.boot.FlowableProperties 完成配置

# 是否开启自动部署流程定义 默认trueflowable.check-process-definitions=true# 流程定义文件位置flowable.process-definition-location-prefix=classpath*:/bpmn/# 流程文件后缀flowable.process-definition-location-suffixes[0]=**.bpmn20.xmlflowable.process-definition-location-suffixes[1]=**.bpmn

5. 自定义ID生成器

public class CustomIdGenerator implements IdGenerator {    @Override    public String getNextId() {        String uuid = UUID.randomUUID().toString();        String nextId = "custom:"   uuid.replaceAll("-", "");        return nextId;    }}

@Beanpublic IdGenerator idGenerator() {    return new CustomIdGenerator();}

6. Flowable配置类

org.flowable.spring.boot.FlowableProperties
org.flowable.spring.boot.process.FlowableProcessProperties
org.flowable.spring.boot.app.FlowableAppProperties
org.flowable.spring.boot.idm.FlowableIdmProperties
org.flowable.spring.boot.FlowableMailProperties
org.flowable.spring.boot.FlowableHttpProperties
