+### Before Route Predicate Factory
+Before route predicate factory接收一个`datetime`参数，参数为ZonedDateTime类型，该predicate匹配发生在某时间之前的请求。
+```yml
+spring:
+  cloud:
+    gateway:
+      routes:
+      - id: before_route
+        uri: https://example.org
+        predicates:
+        - Before=2017-01-20T17:42:47.789-07:00[America/Denver]
+```
+该route匹配发生在2017-01-20T17:42:47.789-07:00[America/Denver]之前的任意请求
+### Between Route Predicate Factory
+Between Route Predicate Factory接收两个参数，都是ZonedDateTime类型，该predicate匹配发生在datetime1和datetime2之间的请求，其中第二个参数指定的时间必须位于第一个参数指定时间之后。如下指定了一个between predicate示例：
+```yml
+spring:
+  cloud:
+    gateway:
+      routes:
+      - id: between_route
+        uri: https://example.org
+        predicates:
+        - Between=2017-01-20T17:42:47.789-07:00[America/Denver], 2017-01-21T17:42:47.789-07:00[America/Denver]
+
+```
+### Cookie Route Predicate Factory
+Cookie Route Predicate Factory接收两个参数，`name`和`regexp`。该predicate匹配请求中含有指定名称，并且cookie值满足`regexp`正则表达式。如下展示了一个cookie predicate示例：
+```xml
+spring:
+  cloud:
+    gateway:
+      routes:
+      - id: cookie_route
+        uri: https://example.org
+        predicates:
+        - Cookie=chocolate, ch.p
+```
+上述cookie_route会匹配请求中含有name为chocolate的cookie，并且cookie值满足`ch.p`正则表达式的请求。  
+### Header Route Predicate Factory
+Header Route Predicate Factory接收两个参数，`header`和`regexp`。
