 ## 升级改造
+0.由于很多项目都使用若伊框架开发，如果放在同一个服务器上，那么cookies和redis的存储会重叠，因此这边做了处理
+```js
+// 前端在appjs把cookie存储的方法加上前缀
+import Cookies from 'js-cookie'
+
+let get_method = Cookies.get
+let set_method = Cookies.set
+let remove_method = Cookies.remove
+Cookies.get = (key) => {
+  return get_method('mz_' + key)
+}
+Cookies.set = (key, value, attributes) => {
+  return set_method('mz_' + key, value, attributes)
+}
+Cookies.remove = (key, attributes) => {
+  return remove_method('mz_' + key, attributes)
+}
+```
+
+```java
+// 后端在redis配置里添加key前缀
+@Component
+public class RedisKeySerializer implements RedisSerializer<String>
+{
+    private final Charset charset;
+    public final static String key = "mz";
+
+    public RedisKeySerializer()
+    {
+        this(Charset.forName("UTF8"));
+    }
+
+    public RedisKeySerializer(Charset charset)
+    {
+        Assert.notNull(charset, "字符集不允许为NULL");
+        this.charset = charset;
+    }
+
+    @Override
+    public byte[] serialize(String string) throws SerializationException
+    {
+        // 通过项目名称ruoyi.name来定义Redis前缀，用于区分项目缓存
+        return new StringBuilder(key).append(":").append(string).toString().getBytes(charset);

+        template.setValueSerializer(serializer);

+        // Hash的key也采用StringRedisSerializer的序列化方式
+        template.setHashKeySerializer(redisKeySerializer);//template.setHashKeySerializer(new StringRedisSerializer());
+        template.setHashValueSerializer(serializer);
+
+        template.afterPropertiesSet();
