flowable工作流-多人会签
突然要用到工作流了，参考大家的博客做了一个小测试，都是自己简单的理解，小记一下。
需求
需求描述：
要求多个人顺序会签同一个任务，一旦有任意一个人审批不通过，则任务视为不通过；直到所有人全部审批通过，则任务才算通过。
需求的流程图设计如下：
要求3个人张三、李四、王五按照顺序审批【员工投票】任务，如果其中任意一个人不同意则流转到【人事审批】任务，如果3个人全部审批通过，则流转到【经理审批】任务。
实现思路分析：
会签任务是否完成主要在于【完成条件】，首先它是boolean值，也就是表达式结果为true时，会签任务结束；表达式结果为false时，会签任务继续（也就是让其他人继续审批）。那么最终网关的走向就是【完成条件】表达式的值再加上【流条件】表达式的值。
实现方式举例：
方式一：
比如【完成条件】表达式的值为${employeeVoteTaskCompleteConfig.completeTaskTo(execution)}，该表达式调用了一个类中的方法，如果要结束会签任务，则需要方法返回结果为true；如果要继续会签任务，则需要方法返回结果为false。
方式二：
比如【完成条件】表达式的值为${approvalStatus == 'finished'}，如果要结束会签任务，则需要设置一个流程变量approvalStatus并且设置为finished；如果要继续会签任务，则设置流程变量approvalStatus不要为finished，任意字符串xxx都可以，让表达式为false即可。
其他方式
略。
流程变量：
无论是哪种配置，核心思想就是控制【完成条件】的结果是true（结束会签任务）还是false（继续会签任务），需要根据实际的业务去写代码做判断。
关于本文档中描述的需求，需要对审批通过的人数进行计数，每有一个人审批通过则计数加1，而对审批通过的人数则不需要计数，因为只要有一个人审批不通过则直接结束会签任务，直接对审批的流条件的值进行判断即可。
方式一：【完成条件(多实例) 】条件表达式实现
1. 流程图
(1)【员工投票】任务配置：
其中【完成条件(多实例) 】的表达式为：${employeeVoteTaskCompleteConfig.completeTaskTo(execution)}

【员工投票】任务审批测试结果
测试用例如下：
- 张三不同意 -> 【人事审批】
- 张三同意，李四不同意 -> 【人事审批】
- 张三同意，李四同意，王五不同意 -> 【人事审批】
- 张三同意，李四同意，王五同意 -> 【经理审批】
同意：审批人完成任务时，设置流程变量result为1；
不同意：审批人完成任务时，设置流程变量result为0；
