spring中自動加上?SimpleKey [] 解決方案

一、自定義后綴名

1、定義類實現KeyGenerator接口

MyKeyGenerator

package com.wbg.springRedis.service.impl;

import org.springframework.cache.interceptor.KeyGenerator;

import org.springframework.stereotype.Component;

import java.lang.reflect.Method;

@Component("myKeyGenerator")

public class MyKeyGenerator implements KeyGenerator {

@Override

public Object generate(Object target, Method method, Object... params) {

//返回后綴名

//return method.getName();

//注意，這里不能返回null,否則會報錯

//java.lang.IllegalArgumentException:

// Null key returned for cache operation (maybe you are using named params on classes without debug info?) Builder[public java.util.List com.wbg.springRedis.service.impl.RoleServiceImpl.listAll()] caches=[listAll] | key='' | keyGenerator='myKeyGenerator' | cacheManager='' | cacheResolver='' | condition='' | unless='' | sync='false'

return "";

}

}

2、注解使用:

@Cacheable(value = "listAll", keyGenerator = "myKeyGenerator")

已經解決

二、自定義前綴：

@Bean

RedisCacheManager cacheManager() {

RedisCacheConfiguration configuration = RedisCacheConfiguration

.defaultCacheConfig()

.computePrefixWith(cacheName -> "redis" + cacheName)

.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.string()))

.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer.java()));

return RedisCacheManager.builder(redisConnectionFactory()).cacheDefaults(configuration).build();

}
