xue2lang opened a new issue #13405:
URL: https://github.com/apache/shardingsphere/issues/13405
## Question
why use not use Properties.put(key,value) instead of
Properties.setProperty(key,value), because setProperty() method only support
String value, when vlaue is Map , Map.toString() (result is k1=v1, k2=v2) have
the equal sign，when we use JSON parse the value from Properties in the
implementation class for SPI will occur error
```java
private static <T extends TypedSPI> void setProperties(final T service,
final Properties props) {
if (null == props) {
return;
}
Properties newProps = new Properties();
//why use not use Properties.put(key,value)
props.forEach((key, value) -> newProps.setProperty(key.toString(),
null == value ? null : value.toString()));
service.setProps(newProps);
}
```
