 ## 后端springboot
+
+### 采用redis缓存
+
+#### 1.pom文件
+```java
+<dependency>
+    <groupId>com.anji-plus</groupId>
+    <artifactId>spring-boot-gaea</artifactId>
+    <version>2.0.3.RELEASE</version>
+    <exclusions>
+        <exclusion>
+            <groupId>org.springframework.boot</groupId>
+            <artifactId>spring-boot-starter-data-redis</artifactId>
+        </exclusion>
+    </exclusions>
+</dependency>
+```
+删除exclusions内容，因为底层默认支持redis
+删除ehcache相关依赖
+
+#### 2.删除 package com.anjiplus.template.gaea.business.cache
+CacheHelper底层默认实现为RedisCacheHelper。
+@ConditionalOnMissingBean 注解起到的作用
+```java
+package com.anji.plus.gaea;
+
+@Configuration
+@EnableConfigurationProperties({GaeaProperties.class})
+public class GaeaAutoConfiguration {
+    @Bean
+    @ConditionalOnClass({RedisAutoConfiguration.class})
+    @ConditionalOnMissingBean
+    public CacheHelper cacheHelper() {
+        return new RedisCacheHelper();
+    }
+}
+```
+
+#### 3.bootstrap.yml加上对应的redis配置即可
