|
|
- 全路径: `org.springframework.core.env.PropertiesPropertySource`
|
|
|
|
- Properties 是 map 结构。可以做类型转换.
|
|
- getPropertyNames 就转换成了父类 MapPropertySource 的方法了
|
|
- map.keySet()
|
|
|
|
```java
|
|
public class PropertiesPropertySource extends MapPropertySource {
|
|
|
|
@SuppressWarnings({"rawtypes", "unchecked"})
|
|
public PropertiesPropertySource(String name, Properties source) {
|
|
super(name, (Map) source);
|
|
}
|
|
|
|
protected PropertiesPropertySource(String name, Map<String, Object> source) {
|
|
super(name, source);
|
|
}
|
|
|
|
|
|
@Override
|
|
public String[] getPropertyNames() {
|
|
synchronized (this.source) {
|
|
return super.getPropertyNames();
|
|
}
|
|
}
|
|
|
|
}
|
|
```
