**Describe the question** Extract the function `getConnection(DbType` dbType, String parameter)` from the `DataSourceService.java` as a public function **What are the current deficiencies and the benefits of improvement** - The getConnection function, which can be used to read/write data in addition to testing the database connection, currently exists as a private function in the 'datasourceservice.java' class: 1. The function itself has nothing to do with the DataSource; its relationship to the function within the DataSourceService should be called/invoked rather than included. 2. Bad for function reuse. 3. When writing a test case for a DataSourceService, it is not easy to use the `mock` agent to mock its execution results because it is a private function **Which version of DolphinScheduler:** -[dev] ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
