上面这些已经在流程变量设置的时候学会了 ，这里略。

错别字：认领任务

![78b146e13ef24270a402251ed62ccb05.png][]![34e77f06c56d4033803400efec3f8b27.png][]

![ca0cf7cb2b7c4a48a41b7990914b9b8a.png][]

设计一个流程，设置候选人

![b22266937dd04987aba43f0e7a50aee9.png][]

错了，应该设置在候选人那里

![7eda303122d94da68cfc383cd0e151e3.png][]

由于修改了流程设计，需要重新部署流程，所以改成leave17.bpmn20.xml

![eabe7b6cd3cb44cdade04e89440d706c.png][]

后来又改成leave18.bpmn20.xml

部署流程：

![cda9fdfdd71449f5ba9c147f8b7bd72f.png][]

启动流程：

![03b8fbc5ab7a45868728b890c5f9aaca.png][]

张三提交申请：

![35307fbd62524051b052f7512fb0799b.png][]

查询任务：

![4d9ced35ff78450090d1a75bf8374cfd.png][]

奇怪，候选人都没有接受到任务，因为张三提交申请中if(task != null)做了判断，没有执行

taskService.complete(task.getId());

查询候选人任务：

![dc19326dc2ff498bb53c09f86d4334ae.png][]

任务责任人为null，所以需要候选人认领任务

候选人认领任务：

![a534249a53744c5ea339a8d3d69287cb.png][]

查询任务：

![f80c7f874ec24602950456d9fc9a7e71.png][]

wangwu已经收到了任务

查询组任务：

![f270c16f15d24ad5a202ea83225c6ff5.png][]

什么都没有，说明wangwu已经把组任务变成了个人任务

任务的归还：

![6476b44fd4a24c828c4fd21b94ca91ec.png][]

归还后查询组任务：

![b2f4787987d24452ab6326969485810a.png][]

候选人lisi认领任务：

![9aef0ceb4d2345d8ab35101dd85edc5d.png][]

查询任务：

![4bdef54189fe4425bc35c9345efa66b0.png][]

lisi完成任务：

![23db1115558b4d279f0be95c8caab5c0.png][]

查询任务：

![d298a863c97d4881bcb7e4fa3e130c2a.png][]

上面文档说的很明白，只要有一个候选人审批就可以

奇怪， 总经理的责任人id为null，想了下，原来是流程设计的时候忘记设置了

可以补充设置下：

map.put("assignee2","周总经理");

![660ada1ccac14a309a9bb375f99f66f9.png][]

这个后面再测试吧

还有任务的交接也后面再测试吧
