Springboot2.x 集成redis

pom.xml 添加

1<dependency>
2           <groupId>org.springframework.boot</groupId>
3           <artifactId>spring-boot-starter-data-redis</artifactId>
4</dependency>

yml 配置

1spring: 
2  redis:
3    #数据库索引
4    database: 0
5    host: 118.24.11.111
6    port: 6379
7    password: 123456
8    jedis:
9      pool:
10        #最大连接数
11        max-active: 8
12        #最大阻塞等待时间(负数表示没限制)
13        max-wait: -1
14        #最大空闲
15        max-idle: 8
16        #最小空闲
17        min-idle: 0
18    #连接超时时间
19    timeout: 10000

21RedisTemplate 配置，重写key和value的序列化
22
23@Configuration
24public class RedisConfig {
25    @Bean
26    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
27        // 配置redisTemplate
28        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
29        redisTemplate.setConnectionFactory(redisConnectionFactory);
30        RedisSerializer stringSerializer = new StringRedisSerializer();
31        redisTemplate.setKeySerializer(stringSerializer); // key序列化
32        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer()); // value序列化
33        redisTemplate.setHashKeySerializer(stringSerializer); // Hash key序列化
34        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer()); // Hash value序列化
35        redisTemplate.afterPropertiesSet();
36        return redisTemplate;
37
38    }
39
40}
41
42public interface RedisService {
43
44    void setObj(String key, Object obj, long timeout);
45
46    Object getObj(String key);
47
48}
49
50@Service("redisService")
51public class RedisServiceImpl implements RedisService {
52    @Resource
53    private RedisTemplate redisTemplate;
54    @Override
55    public void setObj(final String key, Object obj, long timeout) {
56        ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
57        operations.set(key, obj, timeout, TimeUnit.SECONDS);
58    }
59    @Override
60    public Object getObj(final String key) {
61        Object o = redisTemplate.opsForValue().get(key);
62        return o;
63    }
64
65
66}

调用示例

1@Override
2    public User selectByPrimaryKey(Integer id) throws Exception {
3        User user1 = (User)redisService.getObj("user" + id);
4        if(user1 == null){
5            User user = userMapper.selectByPrimaryKey(id);
6            redisService.setObj("user" + id, user, 1000*60*2);
7            return user;
8        }
9        return user1;
10    }
