项目基座需要将redis的链接实现，低代码引擎内置了redis对象，可用户操作redis数据库进行操作

Redis 增删改查操作

示例如下：

  1. // 以 String 值为例
  2. import java.util.UUID;
  3. import java.util.concurrent.TimeUnit;
  5. def TEST_KEY = "agent:aop:test:"
  7. def multiValue = [:];
  9. for(i in 1..9) {
  10.     multiValue[TEST_KEY + i] = "0" + i;
  11. }
  13. json {
  14.     // 判断KEY是否存在
  15.     hasKeyRund1       redis.string().hasKey(UUID.randomUUID().toString())
  16.     // 保存单个值
  17.     setValue0         redis.string().opsForValue().set(TEST_KEY + "0", "00")
  18.     // 判断KEY是否存在
  19.     hasKeyValue0      redis.string().hasKey(TEST_KEY + "0")
  20.     // 保存多个值
  21.     multiSetValue     redis.string().opsForValue().multiSet(multiValue)
  22.     // 检索 key 
  23.     keys              redis.string().keys(TEST_KEY + "*")
  24.     keysAll           redis.string().keys("*")
  25.     // 单个删除
  26.     deleteKey         redis.string().delete(TEST_KEY + "0") 
  27.     // 批量删除
  28.     multiDeleteKey    redis.string().delete(multiValue.keySet())
  29.     // 设置有效期（天）
  30.     setValue1         redis.string().opsForValue().set(TEST_KEY + "0", "00")
  31.     expire            redis.string().expire(TEST_KEY + "0", 1 , TimeUnit.DAYS)
  32.     // 获取有效期（秒）
  33.     getExpire         redis.string().getExpire(TEST_KEY + "0", TimeUnit.SECONDS)
  34.     // 移除有效期
  35.     persist           redis.string().persist(TEST_KEY + "0")
  36.     //  序列化
  37.     dump              redis.string().dump(TEST_KEY + "0")
  38.     //  改名
  39.     rename            redis.string().rename(TEST_KEY + "0", TEST_KEY + "0000000")
  40.     // 随机返回一个 Key
  41.     randomKey         redis.string().randomKey()
  42. }

运行结果：

  1. {"hasKeyRund1":false,"setValue0":null,"hasKeyValue0":true,"multiSetValue":null,"keys":["agent:aop:test:5","agent:aop:test:6","agent:aop:test:2","agent:aop:test:3","agent:aop:test:8","agent:aop:test:4","agent:aop:test:9","agent:aop:test:1","agent:aop:test:7","agent:aop:test:0"],"keysAll":["agent:aop:test:1","agent:aop:test:2","agent:aop:test:0","agent:aop:test:8","agent:aop:test:4","agent:aop:test:7","agent:aop:test:5","agent:aop:test:6","agent:aop:test:9","agent:aop:test:3"],"deleteKey":true,"multiDeleteKey":9,"setValue1":null,"expire":true,"getExpire":86399,"persist":true,"dump":[0,2,48,48,7,0,45,-41,81,124,53,-41,-70,74],"rename":null,"randomKey":"agent:aop:test:0000000"}
