Spring 使用 @EnableCaching 报错

Question

我的项目是 SSM+Shiro+redis
今天要做redis的缓存,采用Spring data redis注解缓存.

redis配置如下:

@Configuration
@EnableCaching
public class CacheConfig {
    
    //缓存管理器
      @Bean  
        public CacheManager cacheManager(RedisTemplate redisTemplate) {  
            RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);  
      
            // Number of seconds before expiration. Defaults to unlimited (0)  
            cacheManager.setDefaultExpiration(3000); // Sets the default expire time (in seconds)  
            return cacheManager;  
        } 
    
      //连接工厂
    @Bean
    public RedisConnectionFactory redisCF(){
        JedisConnectionFactory cf = new JedisConnectionFactory();
        cf.setHostName("192.168.80.155");
        cf.setPort(6379);
        
        return cf;
    }
    
    //RedisTemplate
    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf){
        
        RedisTemplate<String,String> template = new RedisTemplate<String,String>();
        //key会被转换为String类型,非String类型会报错
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        //设置序列化为 json的对象类型,必须实现 serializable接口
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        
        
        
        template.setConnectionFactory(cf);
        template.setKeySerializer(stringRedisSerializer);
        template.setValueSerializer(jackson2JsonRedisSerializer);
        
        return template;
    }
    
//    @Bean
//    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory cf){
//        return new StringRedisTemplate();
//    }

}

然后启动就会报错,再去掉 @EnableCaching,启动正常,不知道什么原因,麻烦大家给分析一下

报错信息:

Register a CacheManager bean or remove the @EnableCaching annotation from your configuration.

最后一个异常信息:

exception is java.lang.IllegalStateException: No bean of type CacheManager could be found. Register a CacheManager bean or remove the @EnableCaching annotation from your configuration.

我在satckoverflow 上找到一个相似的问题,但是看不懂:地址:https://stackoverflow.com/que...

希望知情者解答一下,感激不尽

Answer 1

你的CacheConfig没有覆盖CachingConfigurerSupport
