spring中自动加上 SimpleKey [] 解决方案
一、自定义后缀名
1、定义类实现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) {
//返回后缀名
//return method.getName();
//注意，这里不能返回null,否则会报错
//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")
已经解决
二、自定义前缀：
@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();
}
