idea 集成redis 启动报错

Description:

Parameter 0 of method redisTemplate in org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration required a bean of type ‘org.springframework.data.redis.connection.RedisConnectionFactory‘ that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

The following candidates were found but could not be injected:
    - Bean method ‘redisConnectionFactory‘ in ‘JedisConnectionConfiguration‘ not loaded because @ConditionalOnClass did not find required classes ‘org.apache.commons.pool2.impl.GenericObjectPool‘, ‘redis.clients.jedis.Jedis‘
    - Bean method ‘redisConnectionFactory‘ in ‘LettuceConnectionConfiguration‘ not loaded because @ConditionalOnClass did not find required class ‘io.lettuce.core.RedisClient‘


Action:

Consider revisiting the entries above or defining a bean of type ‘org.springframework.data.redis.connection.RedisConnectionFactory‘ in your configuration.


1.redis引入jar版本是否过低
2. @Autowired改成@Resource

@Autowired

private RedisTemplate<String,Object>redisTemplate;

因为RedisTemplate这个bean的key默认是Object类型的,所以在依赖注入的时候,想将key改为String类型的,所以问题就出在了这里。@Autowired这个注解是根据类型来讲bean注入的,RedisTemplate这个bean在Spring容器中是下图这个样子的,RedisTemplate<object,object>,而我上面写的是RedisTemplate<string,object>,根据类型,Spring容器中没有找到,所以就会报错了;而如果用@Resource的话就可以,因为@Resource这个注解是根据名称在Spring容器中寻找bean的,所以没有问题,这个就是@Autowired和@Resource两个注解的区别

3. private RedisTemplate<String,Object>redisTemplate;  去除<String,Object>

 

重新启动
