1. pom.xmlSpringBoot整合Activiti7需要与SpringSecurity整合。
SpringBoot整合Activiti7之后的所有数据库Id值都使用了类似于UUID样的值。
SpringBoot又封装了一套API来操作Activiti。

activiti:
#1.flase：默认值。activiti在启动时，对比数据库表中保存的版本，如果没有表或者版本不匹配，将抛出异常
#2.true： activiti会对数据库中所有表进行更新操作。如果表不存在，则自动创建
#3.create_drop： 在activiti启动时创建表，在关闭时删除表（必须手动关闭引擎，才能删除表）
#4.drop-create： 在activiti启动时删除原来的旧表，然后在创建新表（不需要手动关闭引擎）
database-schema-update: true
#检测历史表是否存在 activiti7默认没有开启数据库历史记录 启动数据库历史记录
db-history-used: true
#记录历史等级 可配置的历史级别有none, activity, audit, full
#none：不保存任何的历史数据，因此，在流程执行过程中，这是最高效的。
#activity：级别高于none，保存流程实例与流程行为，其他数据不保存。
#audit：除activity级别会保存的数据外，还会保存全部的流程任务及其属性。audit为history的默认值。
#full：保存历史数据的最高级别，除了会保存audit级别的数据外，还会保存其他全部流程相关的细节数据，包括一些流程参数等。
history-level: full
#校验流程文件，true表示自动部署resources下的processes文件夹里的流程文件

4. .bpmn
Candidate Groups候选组，只要是组里面的人都可以拾取任务，办理任务。
Candidate Groups中的内容与上面SpringSecurityConfiguration类中出现的用户组名称要保持一致，可以填写：group1 或者 group2。
