caffeine缓存后台如何获取对应的缓存

如下不同手机号取得不同的验证码我后台如何通过手机号如何取到对应的验证码来验证是否正确呢

package io.nutz.nutzsite.module.open.api;

import io.nutz.nutzsite.common.base.Result;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.nutz.boot.starter.caffeine.Cache;

import org.nutz.mvc.annotation.GET;
import org.nutz.mvc.annotation.Ok;

    public Object getVerificationCode(String phone) {
        if (Strings.isEmpty(phone)) {
            return Result.error("手机号为空");
        }
        log.debug("REST request to send sms : {}" + phone);
        String msg;
        String code = R.captchaNumber(6);;
        msg = "验证码发送成功" + code;
        return Result.success("system.success",msg);
    }
}

这caffeine是缓存页面的？不是通用缓存？

nutzboot caffeine缓存我要如何在程序内查询到呢

不晓得，读一下源码？

大概思路
1、封装一个iocbean 维护一个caffeine对象，配置好caffeine的过期策略
2、在OpenLoginController注入iocbean
3、每发一个验证码，以手机号为key，验证码为value，写入caffeine
4、验证时直接读取手机号key对应的value进行验证即可

近期打算封装一个应用缓存的starter

看了源码获取是这样


    @Override
    public void filter(InterceptorChain chain) throws Throwable {
        Method method = chain.getCallingMethod();
        if (method.getReturnType() == void.class) {
            log.warnf("method [%s] is void,should not use @Cache", method);
            chain.doChain();
            return;
        }
        String name = method.getAnnotation(org.nutz.boot.starter.caffeine.Cache.class).value();
        CacheStrategy strategy = cacheStrategyMap.get(name);
        if (strategy == null) {
            log.warnf("CacheStrategy[%s] on Method[%s] doesn't exist", name, method);
            chain.doChain();
            return;
        }
        Cache<String, Object> cache = getCache(strategy);
        String key = getKey(method, chain.getArgs());
        Object value = cache.getIfPresent(key);
        if (value == null) {
            chain.doChain();
            cache.put(key, chain.getReturn());
        } else {
            chain.setReturnValue(value);
        }
    }

    private String getKey(Method method, Object[] args) {
        String fullName = String.format("%s.%s", method.getDeclaringClass().getName(), method.getName());
        if (args == null || args.length == 0) {
            return fullName;
        }
        return fullName + Arrays.stream(args).map(stringifier::stringify).collect(Collectors.joining("$"));
    }

name=verificationCode
key=io.nutz.nutzsite.module.open.api.OpenLoginController.getVerificationCode18187119326
写了个方法获取对应的值
有没有方法可以获取到注解对应的路径

    public static Object getIfPresent(String name ,String path ,String key) {
        CacheStrategy strategy = cacheStrategyMap.get(name);
        Cache<String, Object> cache = getCache(strategy);
        Object value = cache.getIfPresent(path + key);
        return value;
    }

如何在 static 方法获取配置文件
public static boolean putValue(String name ,String key,Object data) {
CacheStrategy strategy = cacheStrategyMap.get(name);
if(Lang.isNotEmpty(strategy)){
Cache<String, Object> cache = getCache(strategy);
cache.put(name + key, data);
return true;
}
else {
// 获取name对应的配置文件的参数
}
return false;
}

 CacheStrategy strategy = cacheStrategyMap.get(name);
 if(Lang.isNotEmpty(strategy)){
 Cache<String, Object> cache = getCache(strategy);
 cache.put(name + key, data);
 return true;
 }
 else {
// 获取name对应的配置文件的参数
 }
 return false;
