SpringBoot集成Spring Data Redis
实现步骤:
1. 添加Redis起步依赖
<!--spring data redis 依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
2. 在application.properties中配置redis端口、地址
# Redis 配置(不填也是可以的)
spring.redis.host=localhost
spring.redis.port=6379
3. 注入RedisTemplate操作Redis缓存查询所有用户数据
@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("==============从数据库中获取用户数据===================");
}else {
System.out.println("==============从Redis缓存中获取用户数据===================");
}
System.out.println(users);
}
