首先配置StringRedisTemplate使其支援事務

@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate template = new StringRedisTemplate(factory);
        //使其支援事務
        template.setEnableTransactionSupport
 
(true);
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.
 
NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        template.setValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }
}

其次，需要多個對redis的操作（如修改、刪除）使用同一個連線，可以使用stringRedisTemplate.excute(new SessionCallBack<Object>(){ @Override @SuppressWarnings(“unchecked”) public <K, V> Object execute(RedisOperations<K, V> redisOperations) throws DataAccessException { //將各種對redis的操作封裝成一個方法，呼叫即可; return null; } }); })

例如

 public void deleteApiUserTokenInRedis(ApiUser u){
        String apiUserNameKey = KeyUtil.getApiUsernameKey(u.getUserName());
        String apiUserTokenKey = KeyUtil.getApiUserTokenKey(redisService.getByApiUserNameKey(apiUserNameKey));
        redisTemplate.execute(new SessionCallback<String>() {
            @Override
            @SuppressWarnings("unchecked")
            public <K, V> String execute(RedisOperations<K, V> redisOperations) throws DataAccessException {
                //redisSession(list, (RedisOperations<String, String>) redisOperations, tbName);
                delKey(apiUserNameKey,(RedisOperations<String, String>)redisOperations,apiUserTokenKey);
                return null;
            }
        });

    }

     private void delKey(String apiUserNameKey, RedisOperations<String, String> redisOperations, String apiUserTokenKey){
        redisOperations.delete(apiUserNameKey);
        //測試回滾
       // int i = 1/0;
        redisOperations.delete(apiUserTokenKey);
    }
    ```
### 注意：delKey方法中的程式碼不要捕獲異常，否則回滾不會生效。
