import org.springframework.beans.factory.config.YamlPropertiesFactoryBean; import org.springframework.core.env.PropertiesPropertySource; import org.springframework.core.env.PropertySource; import org.springframework.core.io.support.DefaultPropertySourceFactory; import org.springframework.core.io.support.EncodedResource; import java.io.IOException; import java.util.Properties; public class MixPropertySourceFactory extends DefaultPropertySourceFactory { @Override public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException { String sourceName = name != null ? name : resource.getResource().getFilename(); if (!resource.getResource().exists()) { return new PropertiesPropertySource(sourceName, new Properties()); } else if (sourceName.endsWith(".yml") || sourceName.endsWith(".yaml")) { Properties propertiesFromYaml = loadYml(resource); return new PropertiesPropertySource(sourceName, propertiesFromYaml); } else { return super.createPropertySource(name, resource); } } private Properties loadYml(EncodedResource resource) throws IOException { YamlPropertiesFactoryBean factory = new YamlPropertiesFactoryBean(); factory.setResources(resource.getResource()); factory.afterPropertiesSet(); return factory.getObject(); } }使用
