07.SpringBoot整合Redis

SpringBoot整合Redis

一、起步依赖

<!-- 配置使用redis启动器 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

二、application.properties中配置连接信息

#Redis
spring.redis.host=127.0.0.1
spring.redis.port=6379

三、注入测试

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class RedisTemplateTest {

    @Autowired
    private UserRepository userRepository;

    @Autowired
    private RedisTemplate<String,String> redisTemplate;

    @Test
    public void test() throws Exception {

        String userStr = redisTemplate.boundValueOps("user.findAll").get();

        if (userStr == null) {
            List<User> list = userRepository.findAll();
            ObjectMapper om = new ObjectMapper();
            userStr = om.writeValueAsString(list);
            redisTemplate.boundValueOps("user.findAll").set(userStr);
            System.out.println("~~~~~~~~~~ 从数据库中获取数据 ~~~~~~~~~~~~");
        } else {
            System.out.println("~~~~~~~~~~ 从Redis中获取数据 ~~~~~~~~~~~~");
        }

        System.out.println(userStr);

    }
}
