Sådan isoleres spring boot app redis og spring boot session global redis

Som standard er både spring-session og spring-cache faktisk konfigureret af spring-boot med en RedisConnectionFactory bean navngivet som connectionFactory .To måder at gøre dette på.

1. lav spring-session at bruge en anden connectionFactory bean-instans, og lad spring-cache være for at bruge standard connectionFactory . Og nedenfor er en prøveløsning:

   @Configuration
   public class RedisHttpSessionConfig {
   
       @Bean
       StringRedisSerializer stringRedisSerializer() {
           return new StringRedisSerializer();
       }
   
       @Bean
       RedisConnectionFactory redisHttpSessionConnectionFactory() {
           RedisConnectionFactory redisHttpSessionConnectionFactory = null;
           // ... add your codes here
           return redisHttpSessionConnectionFactory;
       }
   
       @Bean
       public RedisTemplate<Object, Object> sessionRedisTemplate(
               RedisConnectionFactory redisHttpSessionConnectionFactory) {
           RedisTemplate<Object, Object> template = new RedisTemplate<Object, Object>();
           template.setKeySerializer(new StringRedisSerializer());
           template.setHashKeySerializer(new StringRedisSerializer());
           template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
           template.setDefaultSerializer(GenericJackson2JsonRedisSerializer());
           template.setConnectionFactory(redisHttpSessionConnectionFactory);
           return template;
       }
   }
   

2. lav spring-cache at bruge en anden connectionFactory bean-instans, og forlad spring-session for at bruge standard connectionFactory . Og nedenfor er en prøveløsning:

   @Configuration
   public class RedisCacheConfig {
   
       @Bean
       StringRedisSerializer stringRedisSerializer() {
           return new StringRedisSerializer();
       }
   
       @Bean
       RedisConnectionFactory redisCacheConnectionFactory() {
            RedisConnectionFactory redisCacheConnectionFactory = null;
            // ... add your codes here
            return redisCacheConnectionFactory;
       }
   
       @Bean
       RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisCacheConnectionFactory) {
           RedisTemplate<Object, Object> redisTemplate = new RedisTemplate();
           redisTemplate.setConnectionFactory(redisCacheConnectionFactory);
           redisTemplate.setKeySerializer(this.stringRedisSerializer());
           redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
           return redisTemplate;
       }
   
       @Bean(name = "stringRedisTemplate")
       public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisCacheConnectionFactory) throws UnknownHostException {
           StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
           stringRedisTemplate.setConnectionFactory(redisCacheConnectionFactory);
           stringRedisTemplate.setKeySerializer(this.stringRedisSerializer());
           stringRedisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
           return stringRedisTemplate;
       }
   
       @Bean
       CacheManager cacheManager(RedisTemplate redisTemplate) {
           RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
           cacheManager.setDefaultExpiration(600l);
           cacheManager.setUsePrefix(true);
           return cacheManager;
       }
   }
