Springboot using the Redis database

　(1) The Pom.xml file introduces the jar package as follows:

<dependency>    <groupId>org.springframework.boot</groupId>    <artifactId> Spring-boot-starter-data-redis</artifactid></dependency>

　(2) The Redis connection information is configured in the Application.properties file as follows:

# Redis Database index (default = 0) spring.redis.database=0# Redis server address spring.redis.host=172.31.19.222# Redis Server connection Port Spring.redis.port=6379# Redis Server connection password (default is empty) Spring.redis.password=# Connection pool Maximum number of connections (using negative values for No limit) Spring.redis.pool.max-active=8# Connection pool maximum blocking wait time (with negative values for No limit) Spring.redis.pool.max- Wait=-1# Maximum idle connection in connection pool Spring.redis.pool.max-idle=8# Minimum idle connection in connection pool spring.redis.pool.min-idle=0# Connection time-out (ms) Spring.redis.timeout=0

(3) Testing the Redis cache

Set ("K5", "Springboot Redis"); returnStringredistemplate.opsforvalue (). Get ("K5"); }}

　　(4) Start the project, call the Reidshandler method, query the Redis server information, as follows:
