springbootcache @cacheevict 无法模糊删除

用@cacheevict删除缓存只能删除指定key的缓存，有些情况需要根据前缀删除所有key的时候，用@cacheevict就做不到了，所以我们自定义一个@cacheremove来处理根据前缀模糊删除所有cache（支持spring el表达式）

以下代码适用于redis

添加依赖

<dependency>    <groupid>org.spri嘴唇起泡怎么办ngframework.boot</groupid>    <artifactid>spring-boot-starter-aop</artifactid></dependency>

启动类加上 @enableaspectjautoproxy

@cacheremove 代码

package com.marssvn.utils.annotation.cache; import java.lang.annotation.retention;import java.lang.annotation.retentionpolicy;import java.lang.annotation.target; import static java.lang.annotation.elementtype.method; @target({method})@retention(retentionpoli孔子的小故事cy.runtime)public @interface cacheremove {     string[] value() default {};}

cacheremoveaspect aop实现类代码

package com.marssvn.utils.annotation.cache.aspect; import com.marssvn.utils.annotation.cache.cacheremove;import org.aspectj.lang.joinpoint;import org.aspectj.lang.annotation.afterreturning;import org.aspectj.lang.annotation.aspect;import org.aspectj.lang.reflect.methodsignature;import org.slf4j.logger;import org.slf4j.loggerfactory;import org.springframework.core.localvariabletableparameternamediscoverer;import org.springframework.data.redis.core.stringredistemplate;import org.springframework.expression.expressionp晋级核潜艇arr;import org.springframework.expression.spel.standard.spelexpressionparr;import org.springframework.expression.spel.support.standardevaluationcontext;import org.springframework.stereotype.component; import javax.annotation.resource;import java.lang.reflect.method;import java.util.t; @aspect@componentpublic class cacheremoveaspect {     @resource    private strin柯达广告语gredistemplate stringredistemplate;     private logger logger = loggerfactory.getlogger(this.getclass());     @afterreturning("@annotation(com.marssvn.utils.annotation.cache.cacheremove)")    public void remove(joinpoint point) {        method method = ((methodsignature) point.getsignature()).getmethod();        cacheremove cacheremove = method.getannotation(cacheremove.class);        string[] keys = cacheremove.value();        for (string key : keys) {            if (key.contains("#"))                key = parkey(key, method, point.getargs());             t<string> deletekeys = stringredistemplate.keys(key);            stringredistemplate.delete(deletekeys);            logger.info("cache key: " + key + " deleted");        }    }     /**     * parkey from spel     */    private string parkey(string key, method method, object [] args){        localvariabletableparameternamediscoverer u =                new localvariabletableparameternamediscoverer();        string[] paranamearr = u.getparameternames(method);         expressionparr parr = new spelexpressionparr();        standardevaluationcontext context = new standardevaluationcontext();         for (int i = 0; i < paranamearr.length; i++) {            context.tvariable(paranamearr[i], args[i]);        }        return parr.parexpression(key).getvalue(context, string.class);    }}

rvice中的调用代码

 孔子见罗雀者翻译 /**     * delete repository     *     * @param id repositoryid     */    @override    @transactional    @cacheremove({"repository.list::*", "'repository::id=' + #id", "'repository.tree::id=' + #id + '*'"})    public void deleterepositorybyid(int id) {         //  business code    }

@cacheevict根据缓存名称模糊删除

@cacheevict(cachenames = "likename" ,allentries=true)

看源码可知
