修改配置

#关闭定时任务JOB
async-executor-activate: false
database-schema-update: true
server:
port: 8081配置说明：
> database-schema-update: true
数据库更新策略，其取值有四个：
flase： 默认值。activiti在启动时，会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。（生产环境常用）
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。（开发时常用）
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）。（单元测试常用）
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）。定义流程文件
这里还是用一个开源的流程文件
放在：resources/processes/ExpenseProcess.bpmn20.xml
