获取数据源换行
String dataSources = propertyResolver.getProperty("names");


建议   OrchestrationSpringBootConfiguration文件

line77

String dataSources = propertyResolver.getProperty("names");

加一个去空格处理

改为  String dataSources = propertyResolver.getProperty("names").trim();

### Which version of Sharding-Jdbc do you using?

### Expected behavior

### Actual behavior

### Steps to reproduce the behavior

### Please provide the reproduce example codes (such as github link)

Code should based on https://github.com/shardingjdbc/sharding-jdbc-example
