SpringBoot integration Mybatis detailed process

Create a SpringBoot project

Add the Redis dependency package

<! -- Redis dependencies -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
Copy the code

Configure the Redis database connection

Configure the redis database connection information in application.properties as follows:

#Redis server address
spring.redis.host=127.0.0.1
#Redis server connection port
spring.redis.port=6379
#Redis database index (default 0)
spring.redis.database=0
# maximum number of connections in the pool (use negative values to indicate no limit)
spring.redis.jedis.pool.max-active=50
Maximum connection pool blocking wait time (negative value indicates no limit)
spring.redis.jedis.pool.max-wait=3000
The maximum number of free connections in the connection pool
spring.redis.jedis.pool.max-idle=20
Minimum free connection in connection pool
spring.redis.jedis.pool.min-idle=2
Connection timeout (ms)
spring.redis.timeout=5000
Copy the code

Write Redis operation utility classes

@Component
public class RedisUtils {

    @Autowired
    private RedisTemplate redisTemplate;

    /** * read cache **@param key
     * @return* /
    public Object get(final String key) {
        return redisTemplate.opsForValue().get(key);
    }

    /** * write cache */
    public boolean set( String key, Object value) {
        boolean result = false;
        try {
            redisTemplate.opsForValue().set(key, value,1, TimeUnit.DAYS);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    /** * update the cache */
    public boolean getAndSet(final String key, String value) {
        boolean result = false;
        try {
            redisTemplate.opsForValue().getAndSet(key, value);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    /** * delete cache */
    public boolean delete(final String key) {
        boolean result = false;
        try {
            redisTemplate.delete(key);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        returnresult; }}Copy the code
