本文重点讲解flowable 集成spring boot的过程，flowable与spring boot整合的问题。

1.项目工程的搭建。

2.application.properties文件的配置。

3.测试

4.效果

1.项目工程的搭建

我们直接新建一个普通的maven工程即可，其中pom.xml文件内容如下：

<parent>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-parent</artifactId>
   	<version>1.3.0.M1</version>
   	<relativePath /> <!-- lookup parent from repository -->
   	</parent>
   	<properties>
   	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   	<java.version>1.8</java.version>
   	</properties>
   	<dependencies>
   	<dependency>
   	<groupId>org.flowable</groupId>
   	<artifactId>flowable-spring-boot-starter-basic</artifactId>
   	<version>6.0.1</version>
   	</dependency>
   	<!-- <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring-boot-starter-basic</artifactId>
   	<version>5.21.0</version> </dependency> -->
   	<dependency>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-velocity</artifactId>
   	</dependency>
   	<dependency>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-web</artifactId>
   	</dependency>
   	<!-- https://mvnrepository.com/artifact/joda-time/joda-time -->
   	<dependency>
   	<groupId>joda-time</groupId>
   	<artifactId>joda-time</artifactId>
   	<version>2.8.2</version>
   	</dependency>
   	<dependency>
   	<groupId>mysql</groupId>
   	<artifactId>mysql-connector-java</artifactId>
   	</dependency>
   	<dependency>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-test</artifactId>
   	<scope>test</scope>
   	</dependency>
   	<dependency>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-data-jpa</artifactId>
   	</dependency>
   	</dependencies>

其中项目工程目录结构如下图所示：

2.application.properties文件的配置

application.properties文件的内容如下：

spring.jpa.hibernate.ddl-auto=update

spring.jpa.database=MYSQL

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/activiti_springboot

spring.datasource.username=root

spring.datasource.password=

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

flowable.check-process-definitions=false

3.Application.java

Application.java文件的内容如下：

@RestController
@SpringBootApplication()
public class Application {
   	@RequestMapping("/task")
   	String task() {
   	System.out.println("################################" + taskService);
   	return taskService.toString();
   	}
   	@Autowired
   	private TaskService taskService;
   	@Autowired
   	private ProcessEngine processEngine;
   	@RequestMapping("/")
   	String index() {
   	System.out.println("################################taskService" + taskService);
   	System.out.println("################################processEngine" + processEngine);
   	return "xxxxxxxxxxxxx";
   	}
   	public static void main(String[] args) {
   	SpringApplication springApplication = new SpringApplication(Application.class);
   	springApplication.run(args);
   	}
}

运行上述代码，数据库的变化如下所示，换言之我们已经成功flowable 集成spring boot，程序输出如下：

################################taskServiceorg.flowable.engine.impl.TaskServiceImpl@5a9827c7

################################processEngineorg.flowable.engine.impl.ProcessEngineImpl@6c154076
