19、SpringBoot 使用Redis作为缓存

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

    @Autowired
    RedisTemplate redisTemplate;
    @Autowired
    StringRedisTemplate stringRedisTemplate;

    @Autowired
    RedisTemplate<Object, Object> myRedisTemplate;

    @Test
    void test() {
        //stringRedisTemplate.opsForValue().set("msg","hello,word");
        Employee empId = employeeService.getEmpId(1);
        myRedisTemplate.opsForValue().set("emp-01",empId);
    }

@Configuration
public class MyRedisConfig {

    @Bean
    public RedisTemplate<Object, Object> myRedisTemplate(RedisConnectionFactory redisConnectionFactory)
            throws UnknownHostException {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        Jackson2JsonRedisSerializer<Object> serializer = new Jackson2JsonRedisSerializer(Object.class);
        template.setDefaultSerializer(serializer);
        return template;
    }
}

public class Employee implements Serializable
