# 方法缓存
|
||||
  @Cached注解在Service的方法上,实现对方法结果进行缓存。
|
||||
     1、返回类型不能是```void```/```CompletableFuture<Void>```<br>
|
||||
     2、返回类型必须是可json序列化的 <br>
|
||||
     3、修饰必须是```protected```/```public``` <br>
|
||||
     4、修饰不能是```final```/```static``` <br>
|
||||
|
||||
  将结果进行本地缓存30秒
|
||||
```java
|
||||
@Cached(key = "name", localExpire = "30")
|
||||
public String getName() {
|
||||
return "haha";
|
||||
}
|
||||
```
|
||||
|
||||
  以参数code为key将结果进行本地缓存(时长由环境变量```env.cache.expire```配置,没有配置采用默认值30秒)、远程缓存60秒
|
||||
```java
|
||||
@Cached(key = "#{code}", localExpire = "${env.cache.expire:30}", remoteExpire = "60")
|
||||
public CompletableFuture<String> getNameAsync(String code) {
|
||||
return CompletableFuture.completedFuture(code);
|
||||
}
|
||||
```
|
||||
|
||||
  以参数code+map.id为key将结果进行远程缓存60毫秒
|
||||
```java
|
||||
@Resource
|
||||
private CacheManager cacheManager;
|
||||
|
||||
//实时修改远程缓存的key值
|
||||
public void updateName(String code, Map<String, Long> map) {
|
||||
cacheManager.remoteSetString(code, code + "_" + map.get("id"), Duration.ofMillis(60));
|
||||
}
|
||||
|
||||
@Cached(key = "#{code}_#{map.id}", remoteExpire = "60", timeUnit = TimeUnit.MILLISECONDS)
|
||||
public String getName(String code, Map<String, Long> map) {
|
||||
return code + "-" + map;
|
||||
}
|
||||
```
