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
