+### 23.6.3. Multi-profile YAML文档
+
+你可以在单个文件中定义多个特定配置（profile-specific）的YAML文档，并通过一个spring.profiles key标示应用的文档。例如：
+```json
+server:
+    address: 192.168.1.100
+---
+spring:
+    profiles: development
+server:
+    address: 127.0.0.1
+---
+spring:
+    profiles: production
+server:
+    address: 192.168.1.120
+```
+在上面的例子中，如果development配置被激活，那server.address属性将是127.0.0.1。如果development和production配置（profiles）没有启用，则该属性的值将是192.168.1.100。
