snakeflow的springboot项目-编程知识

Gitee搜索“liuxz/snakerflow”，它是spring boot集成了一款国产工作流引擎snakerflow。

下面是安装步骤：

创建数据库snaker-web，字符集设置成utf8mb4和utf8mb4_generic。不然的话，中文插入不进去。
在这里插入图片描述
运行sql命令

修改resources/config/develop/application.properties文件

spring.datasource.url = jdbc:mysql://localhost:3306/snaker_web?useUnicode=true&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = root

password改成您的mysql密码。

启动项目。
用postman发送/deploy请求
在这里插入图片描述
将上面的processId替换TestController代码中的processId

@RequestMapping(value = "/getProcess", method = RequestMethod.GET)public ResponseData getProcess() {String processId = "ad69f85bc8be4391ab689060f0b024ce";String operator = "liuxzh_userId";Map<String, Object> args = new HashMap<String, Object>();args.put("quanju var", "全局变量");Order order = snakerEngineFacade.startInstanceById(processId, operator, args);if (StringUtils.isNotBlank(order.getId())) {System.out.println(order.getId());return ResponseData.ok().putDataValue("message","启动流程实例成功");} else {return ResponseData.notFound();}}
