因为mysql使用schema标识库名而不是catalog，因此mysql会扫描所有的库来找表，如果其他库中有相同名称的表，activiti就以为找到了，本质上这个表在当前数据库中并不存在。
设置nullCatalogMeansCurrent=true，表示mysql默认当前数据库操作，在mysql-connector-java 5.xxx该参数默认为true，在6.xxx以上默认为false，因此需要设置nullCatalogMeansCurrent=true
yml数据源配置：
url: jdbc:mysql://localhost:3306/ry-vue?useUnicode=true&characterEncoding=utf8&nullCatalogMeansCurrent=true&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
