ConfigurationPropertyName (Spring Boot 2.6.4 API)

java.lang.Object
- org.springframework.boot.context.properties.source.ConfigurationPropertyName

All Implemented Interfaces:

Comparable<ConfigurationPropertyName>
```
public final class ConfigurationPropertyName
extends Object
implements Comparable<ConfigurationPropertyName>
```
A configuration property name composed of elements separated by dots. User created names may contain the characters "a-z" "0-9") and "-", they must be lower-case and must start with an alpha-numeric character. The "-" is used purely for formatting, i.e. "foo-bar" and "foobar" are considered equivalent.
The "[" and "]" characters may be used to indicate an associative index(i.e. a Map key or a Collection index). Indexes names are not restricted and are considered case-sensitive.
Here are some typical examples:
- spring.main.banner-mode
- server.hosts[0].name
- log[org.springboot].level
Since:

2.0.0
