启动一个FlowableRest的最小

前言

初步接触flowable时候一直很疑惑flowable rest到底怎么在项目里使用，如何配置，其实非常的简单，因为是用的springboot，已经配置好了，我们只需要在pom.xml文件中引入flowable-spring-boot-starter-process-rest这个包就可以了，下面就记录一下创建一个FlowableRest的后端项目。

项目结构如下：

一、创建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>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>devtao</groupId>
    <artifactId>FlowableRest</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <flowable.version>6.4.2</flowable.version>
    </properties>

    <dependencies>

        <!-- Spring Boot-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!--工作流依赖-->

        <!--flowable工作流依赖-->
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter</artifactId>
            <version>${flowable.version}</version>
        </dependency>
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter-process-rest</artifactId>
            <version>${flowable.version}</version>
        </dependency>


        <!--mysql依赖-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.22</version>
        </dependency>

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.21</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.21</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>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

二、创建springboot的启动类

SpringBootRestApplication.java

package devtao;

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

@SpringBootApplication
public class SpringBootRestApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootRestApplication.class, args);
    }

}

三、创建配置文件

application.yml

server:
  port: 8999

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/study_flowable?nullCatalogMeansCurrent=true&amp&useSSL=false&useUnicode=true&characterEncoding=utf8&serverTimezone=GMT
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
  resources:
#    static-locations: classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,classpath:/static/flowable-modeler
flowable:
  #关闭定时任务JOB
  async-executor-activate: false

四、测试

启动springboot，用postman测试，可以发现正常返回结果。

ok，到此为止一个最简单的flowable-rest项目已经启动完成，对分布式项目，调用flowable基本上都是使用的rest服务。
