I love the java series --- [springboot integration redis]

SpringBoot集成Spring Data Redis

Implementation steps:

1. Add start dependent Redis

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

Configuring redis port address in the application.properties

# Redis configuration (not fill are possible)
spring.redis.host=localhost
spring.redis.port=6379

3. Fill RedisTemplate operating Redis cache query all user data

@Autowired
private RedisTemplete redisTemplete

@Test
public void testRedis() throws JsonProcessingException {
String users = (String)redisTemplate.boundValueOps("user.findAll").get();
if (users == null) {
List<User> userList = userMapper.queryUserList();
ObjectMapper jsonFormat = new ObjectMapper();
users = jsonFormat.writeValueAsString(userList);
redisTemplate.boundValueOps("user.findAll").set(users);
System.out.println ( "Get ============== =================== user data from the database");
}else {
System.out.println ( "Get ============== =================== user data from the cache Redis");
 }
System.out.println(users);
}
