When SpringBoot integrates mybatis, when using Autowired to inject RedisTemplate, an error is reported: I don’t know which one to implement because there are multiple beans.

1. RedisTemplate cannot be injected using @Autowired

1.1 Error code

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

1.2 Error message

***************************
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. The reason for the error

After importing Redis dependencies in Spring Boot, SpringBoot will automatically help us generate a RedisTemplate and a StringRedisTemplate in the container, so it will report:

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
