### 本示例组件 ###

> 1.  Spring-Boot: (v2.0.1.RELEASE)
> 2.  Camunda BPM: (v7.10.0)
> 3.  Camunda BPM Spring Boot Starter: (v3.2.1)
> 4.  Spring Clound： (Finchley.RELEASE)
> 5.  JDK: (v1.8)
> 6.  Mysql: (v5.7)
> 7.  其他见pom.xml

### 项目启动步骤 ###

1、通过 git clone [https://gitee.com/camunda/CamundaSpringBootDemo.git][https_gitee.com_camunda_CamundaSpringBootDemo.git] 拉去camunda源码

通过git clone [https://gitee.com/camunda/eureka.git][https_gitee.com_camunda_eureka.git] 拉取 eureka 的源码

2、创建camunda数据库，修改application.yml中的mysql连接配置或应用服务的端口，默认为8089；

3、通过mvn spring-boot:run 启动应用，应用启动时会自动创建数据库表并进行初始化

4、打开浏览器并访问 [http://localhost:8089][http_localhost_8089]，使用kermit/superSecret登录Camunda Webapp，里边有Admin、Cockpit、TaskList应用，在Admin中添加用户

5、打开浏览器并访问 [http://localhost:8089/swagger-ui.html][http_localhost_8089_swagger-ui.html]

6、打开浏览器并访问 [http://localhost:8089/cmaunda-swagger-ui.html，查看原生Camunda][http_localhost_8089_cmaunda-swagger-ui.html_Camunda] REST API;

### 流程建模 ###

1、打开浏览器并访问  [http://localhost:8089/modeler.html][http_localhost_8089_modeler.html] ，这个是网页版的流程模型编辑器实例，编辑好流程放到[/src/main/resources/][src_main_resources]下，带自动重启好后，流程就可以使用了

2、PC端的请使用[Camunda Modeler][]，创建好模型后使用工具栏最右边的按钮打开部署窗口，URL中输入：[http://localhost:8089/engine-rest/engine/default/deployment/create，填写Name流程名称，和Authentication使用http][http_localhost_8089_engine-rest_engine_default_deployment_create_Name_Authentication_http] basic并输入kermit/superSecret，然后执行Deploy部署流程

3、登录Cockpit查看已部署的流程

### 测试接口 ###

1、SimpleProcessHandlerImpl 是使用Java API 实现的流程操作功能

2、SimpleRestProcessHandlerImpl 使用REST API 实现的流程操作功能

### 引擎配置 ###

在/src/main/resources/META-INF/的processes.xml，为空时,默认内容如下，详细请查看[Configure Process Engine in the processes.xml][]
