Spring Boot2 整合Redis

Spring 版本爲  2.1.5.RELEASE

 

整合依賴

<!--redis的starter-->
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-redis</artifactId>
   <version>1.4.7.RELEASE</version>
</dependency>

 

在yml文件中配置redis

#TODO redis 配置
  redis:
    database: 0
    host: 127.0.0.1
    port: 6379
    timeout: 2000s
#    password: root

 

編寫  RedisConfig 配置類

 

@Configuration
public class RedisConfig {
    @Bean(name = "adminRedisTemplate")
    public RedisTemplate<String, Object> redisTemplate (RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String,Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(redisConnectionFactory);

        /*使用Jackson2JsonRedisSerializer來序列化和反序列化redis的value的值(默認使用的是JDK序列化方式)*/
        Jackson2JsonRedisSerializer<Object> json = new Jackson2JsonRedisSerializer<Object>(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        json.setObjectMapper(objectMapper);

        /*使用StringRedisSerializer來序列化和反序列化redis的key值*/
        RedisSerializer redisSerializer = new StringRedisSerializer();


        /*value*/
        template.setValueSerializer(json);
        template.setHashValueSerializer(json);
        /*key*/
        /*key的序列化採用StringRedisSerializer*/
        template.setKeySerializer(redisSerializer);
        template.setHashKeySerializer(new StringRedisSerializer());

        template.afterPropertiesSet();
        return template;
    }
    
}

 

 

編寫通用的RedisServcie （方便在其他的業務類中直接注入@Autowired）

@Service
public class RedisService<T> {

    @Autowired
    @Qualifier("adminRedisTemplate")
    private RedisTemplate<String, Object> redisTemplate;

    public void setObj(String key, T value) {
        redisTemplate.opsForValue().set(key, value);
    }


    public T getObj(String key) {
        return (T) redisTemplate.opsForValue().get(key);
    }


}

 

在業務controller中測試效果

@Autowired
private RedisService<Admin> redisService;






 @RequestMapping(value = "/testAdminRedis")
 public String testAdminRedis(){
        Admin admin = new Admin();
        admin.setAdmName("測試admin");
        admin.setAdmPsw("123");
        admin.setAdmLastLoginTime(new Date());
        redisService.setObj("admin01", admin);
        return admin.toString();
 }


@RequestMapping(value = "/getAdminMessage")
@ResponseBody
public String getAdminMessage() {
        Admin admin = redisService.getObj("admin01");
        return JSON.toJSONString(admin);
}
