一、说明

        1、查询增加缓存，使用@Cacheable注解

        2、项目中已经用到了ehcache，现在需求是两个都用

二、备份配置

1、redisConfig增加代码

@Bean("redisCacheManage")@Primarypublic CacheManager redisCacheManager(RedisConnectionFactory factory) {Map<String, RedisCacheConfiguration> configurationMap = MapUtil.newHashMap();RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig().entryTtl(Duration.ofMinutes(60)).serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(keySerializer())).serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(valueSerializer())).disableCachingNullValues();return RedisCacheManager.builder(factory).initialCacheNames(configurationMap.keySet()).withInitialCacheConfigurations(configurationMap).cacheDefaults(config).build();}private RedisSerializer<String> keySerializer() {return new StringRedisSerializer();}private RedisSerializer<Object> valueSerializer() {Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer =new Jackson2JsonRedisSerializer<>(Object.class);ObjectMapper objectMapper = new ObjectMapper();objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);// 此项必须配置，否则如果序列化的对象里边还有对象，会报如下错误：//     java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to XXXobjectMapper.activateDefaultTyping(objectMapper.getPolymorphicTypeValidator(),ObjectMapper.DefaultTyping.NON_FINAL,JsonTypeInfo.As.PROPERTY);// 旧版写法：// objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);jackson2JsonRedisSerializer.setObjectMapper(objectMapper);return jackson2JsonRedisSerializer;}

2、直接使用

1）缓存

@Cacheable(key ="'method_' + #tenantId + '_' + #bo.toString()", unless = "#result == null", cacheManager = "redisCacheManage", cacheNames = "api")

说明1：cacheNames其实是个前缀，也可以理解成分组的概念；方便手动删除时，根据前缀删除

2）示例截图

3）redis存储结果截图
