我的项目中需要同时使用oceanbase的mysql模式和oracle模式 在我配置了动态数据源并使用PageAutoDialect分别注册了oceanbase:oracle=OracleDialect，oceanbase=MysqlDialect后，PageAutoDialect的fromJdbcUrl在识别url时并没有优先匹配oracle，而是优先匹配了mysql，因为该方法对dialectAliasMap的keySet进行循环时，keySet并不是按照我添加的顺序进行循环的，导致在这种场景下无法正确对oracle和mysql双模式的数据源进行分页，恳请优化

如果和顺序有关，dialectAliasMap换LinkedHashMap能否解决？可以来个PR。

map的keySet返回的是Set 而java的Set接口并不保证排序 所以不应该用 需要单独建立一个List来存储key来循环
但不知道是否有更好的办法
