Class AbstractPropertySourceLoader

java.lang.Object

com.alibaba.cloud.nacos.parser.AbstractPropertySourceLoader

All Implemented Interfaces:

org.springframework.boot.env.PropertySourceLoader

Direct Known Subclasses:

NacosJsonPropertySourceLoader, NacosXmlPropertySourceLoader

public abstract class AbstractPropertySourceLoader
extends Object
implements org.springframework.boot.env.PropertySourceLoader

Nacos-specific loader, If need to support other methods of parsing,you need to do the following steps:

1.inherit AbstractPropertySourceLoader;
2. define the filespring.factories and append org.springframework.boot.env.PropertySourceLoader=..;
