SpringBoot整合mybatis时，使用Autowired注入RedisTemplate时，报错：因有多个bean不知实现哪一个的问题

1、使用@Autowired无法注入RedisTemplate

1.1 报错代码

@RestController
public class StudentController {
     
 
    @Autowired
    private RedisTemplate redis;
    
    @PostMapping("set")
    @ResponseBody
    public void set(@RequestBody Student student){
     
        redis.opsForValue().set("student",student);
    }

1.2 报错信息

***************************
APPLICATION FAILED TO START
***************************
Description:
Field redis in com.springboot.demo.controller.StudentController required a single bean, but 2 were found:
	- redisTemplate: defined by method 'redisTemplate' in class path resource [org/springframework/boot/autoconfigure/data/redis/RedisAutoConfiguration.class]
	- stringRedisTemplate: defined by method 'stringRedisTemplate' in class path resource [org/springframework/boot/autoconfigure/data/redis/RedisAutoConfiguration.class]
Action:
Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
Process finished with exit code 1

2、报错原因

当在Spring Boot中导入Redis依赖后，SpringBoot会自动帮我们在容器中生成一个RedisTemplate和一个StringRedisTemplate，所以会报：

Consider marking one of the beans as @Primary, 
updating the consumer to accept multiple beans, 
or using @Qualifier to identify the bean that should be consumed
