How to use redis introduced by SpringBoot

1. Install the windows version of redis

Since the windows redis is only used for personal testing and play, here is a simple download of the zip decompression version

Use it in the directory where you decompress it Start the server with the following command: (Since the win10 powershell is used here, you need to add ./, or you can avoid using ./ by configuring environment variables)

./redis-server.exe redis.windows.conf

　　　 // It will not be registered as a windows service here. Now, close the window and close redis

Start the command terminal:

./redis-cli.exe -h 127.0.0.1 -p 6379

2. Introduce dependencies

 <!-- springboot整合redis -->  
        <dependency>  
            <groupId>org.springframework.boot</groupId>  
            <artifactId>spring-boot-starter-data-redis</artifactId>  
        </dependency>

You only need to introduce this one here Just rely on redis, and the other three will automatically depend on:

3. Configure redis in application.yml

spring.redis.host=127.0.0.1
#Redis server connection port
spring.redis.port=6379
#Redis server connection password (default is empty)
spring.redis.password=
#Maximum number of connections in the connection pool (use a negative value to indicate no limit)
spring.redis.pool.max-active=8
#Maximum blocking waiting time of the connection pool (use a negative value to indicate no limit)
spring.redis.pool.max-wait=-1
#Maximum idle connection in the connection pool
spring.redis.pool.max-idle=8
#Minimum idle connection in the connection pool
spring.redis.pool.min-idle=0
#Connection timeout (milliseconds)
spring.redis.timeout=30000

4. Register Redis as a local service

Normally we can start the redis service through redis-server.exe and the configuration file:

redis-server.exe redis.windows.conf

In addition Open a command line window redis-cli.exe to do some simple operations. Command line

But if we close the console, the Redis service will also be closed together, and we have to execute the command when we want to use it. Restarting the redis service is very inefficient and troublesome.

There is a concept of local service in Windows. Our goal is to register Redis as a service here, and then it will not be affected by console exit.

Register as a local service:

redis-server.exe –service-install redis.windows.conf

From the picture, we can see that the authorization and registration have been successful. Next, we go to the windows service (right-click the windows menu-"Computer Management-"Services and Applications-"Services) to see if there is a redis service:

Command rules

Register service redis-server –service-install redis.windows.conf

Delete service redis-server –service-uninstall

Start service redis-server –service-start

Stop service redis-server –service-stop

5.Usage of Redis

    @Autowiredprivate StringRedisTemplate redisTmp;

    @GetMapping("/api/setkey")public String setkey(String keyname,String keyvalue){
        String value = "Set Value OK";try{
            redisTmp.opsForValue().set(keyname,keyvalue);
        }catch (Exception ex){
            value = "Set Error :"+ex.getMessage();
        }return value;
    }
    @GetMapping("/api/getkey")public String getkey(String keyname){
        String str = "";try {
            Boolean isHas = redisTmp.hasKey(keyname);if (isHas){
                str = redisTmp.opsForValue().get(keyname).toString();
            }else {
                str = "抱歉！不存在key值为"+keyname;
            }
        } catch (Exception ex){
            str = ex.getMessage();
        }return str;
    }
