Redis整合SpringBoot

说明:在SpringBoot2.x之后,原来使用的jedis被替换为了lettuce?

测试连接

    @Test
    void contextLoads() {
        //获取连接对象
        RedisConnection connection = redisTemplate.getConnectionFactory().getConnection();
        System.out.println(connection.ping());

        redisTemplate.opsForValue().set("name","bzm");
        System.out.println(redisTemplate.opsForValue().get("name"));
    }

真实开发，一般使用json来传递对象

创建User对象

@Component
@AllArgsConstructor
@NoArgsConstructor
@Data
//在企业中所有的pojo对象都会序列化
public class User implements Serializable {
    private String name;
    private int age;
}

测试

@Test
    void test() throws JsonProcessingException {
        //真实开发，一般使用json来传递对象
        User user = new User("Bzm", 18);
        String jsonUser = new ObjectMapper().writeValueAsString(user);
        redisTemplate.opsForValue().set("user",jsonUser);
    }

{“name”:“Bzm”,“age”:18}

@Test
    void test() throws JsonProcessingException {
        //真实开发，一般使用json来传递对象
        User user = new User("Bzm", 18);
//        String jsonUser = new ObjectMapper().writeValueAsString(user);
        redisTemplate.opsForValue().set("user",user);
        System.out.println(redisTemplate.opsForValue().get("user"));
    }

User(name=Bzm, age=18)

	@Bean
    @SuppressWarnings("all")
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {
        //我们为了自己开发方便，- -般直接使用
        RedisTemplate template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);

        //Json序列化配置
        Jackson2JsonRedisSerializer
