Field redisTemplate in com.lzp.controller.test.RedisController required a bean of type 'org.springframework.data.redis.core.RedisTemplate' that could not be found.

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


Action:

Consider defining a bean of type 'org.springframework.data.redis.core.RedisTemplate' in your configuration.

报错代码

@ApiIgnore
@RestController
@RequestMapping("redis")
public class RedisController {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    @GetMapping("/get")
    public Object get(String key) {
        return redisTemplate.opsForValue().get(key);
    }
}

解决方法：删除RedisTemplate泛型指定。

No qualifying bean of type ‘org.springframework.data.redis.core.RedisTemplate< java.lang.String, java.lang.Object>。

官网，连接Redis一节有注释

If you add your own @Bean of any of the auto-configured types, it replaces the default (except in the case of RedisTemplate, when the exclusion is based on the bean name, redisTemplate, not its type). 

上面的RedisTemplate< String, Object>注入时用到了@Autowired，@Autowired默认按照类型装配的。也就是说，想要获取RedisTemplate< String, Object>的Bean，要根据名字装配。那么自然想到使用@Resource，它默认按照名字装配。因此修改成下面代码，能够正常启动应用。

@Resource
private RedisTemplate<String, Object> redisTemplate;

其次，StringRedisTemplate类的父类就是RedisTemplate< String, String>，而Bean默认是单例的，两个是自然是同一个对象了。因此，也可以使用下面的注入方式。

@Autowired
private RedisTemplate<String, String> redisTemplate;
