   > You should use the same sourceDatasource configuartion in docs.
   
   It works, but another question floats out water. It's 
'java.lang.ClassCastException'.
   It happens in the first step--unmarshal the inline yaml to get 
DataSourceConfiguration
   Maybe It's a bug?  @kimmking 
   
   ### This is the debug picture
   _ConfigurationYamlConverter ,lines 48_
   
![classCastException](https://user-images.githubusercontent.com/43491115/91698574-87e0a880-eba5-11ea-9ffd-7cb1b4d5ba72.png)
   
   YamlEngine doesn't convert LinkedHashMap to YamlDataSourceConfiguration 
automatically, after I add the convertion, the problem go away

   ### param "data" of this method 
   
   
   ```java
   data = "ds_source: \n" +
                   "  dataSourceClassName: 
com.zaxxer.hikari.HikariDataSource\n" +
                   "  properties:\n" +
                   "    jdbcUrl: 
jdbc:mysql://10.16.10.42:33307/columbia_limadw?serverTimezone=UTC&useSSL=false\n"
 +
                   "    username: root\n" +
                   "    password: '''123456'''\n" +
                   "    connectionTimeout: 30000\n" +
                   "    idleTimeout: 60000\n" +
                   "    maxLifetime: 1800000\n" +
                   "    maxPoolSize: 50\n" +
                   "    minPoolSize: 1\n" +
                   "    maintenanceIntervalMilliseconds: 30000\n" +
                   "    readOnly: false\n";
   ```
